INTRODUCTION
The SF1000 is a serial-interfaced flash memory card designed to work with
Rabbit Semiconductor’s single-board computers and RabbitCore modules.
All Rabbit-based boards can use the SF1000 with either a synchronous
serial peripheral interface (SPI) or an emulated SPI via parallel I/O ports.
Zilog Z180-based single-board computers must use the emulated SPI
method.
Two SF1000 models are presently offered, as shown in Table 1.
Larger memories may be possible in the future when parts become available.
Throughout this manual, the term SF1000 refers to all the models shown in
Table 1; specific models are identified according to their name in Table 1.
These serial flash cards are ideal for applications that require the temporary
storage of large amounts of data. This data can be retrieved or downloaded
to another system via the controlling single-board computer using TCP/IP
or serial communication, or the card itself may be removed to facilitate
transferring the data to another location.
The Dynamic C implementation of the FAT file system can be used with
the SF1000 serial flash cards to store and access the data via a directory
structure that can be accessed through Unix or DOS style paths. The
standard directory structure allows for monitoring, logging, Web browsing,
and FTP updates of the files.

GETTING STARTED
Headers
The SF1000 comes with a 10-pin, 2 mm, 5×2 header located at J1 as shown
in Figure 1. Headers, either plugs or sockets, SMT or through-hole, may
also be installed at J2 or J3. The pinouts for these positions are identical,
and allow for a connecting cable to be hooked up in different ways. There
is also a location at J4 for a 7-pin in-line header or socket with 0.1" spacing.
Position 6 at J4 is not used, which allows this connection to be keyed.

Pinout
Only six connections are required to interface the SF1000 with a Rabbit
Semiconductor board:
• +5 V
• Ground
• Chip Select input
• Serial Clock Input
• Serial Data Input
• Serial Data Output. This output is inverted because the serial flash is a
3 V part and the signal is converted to 5 V via an inverting transistor
buffer.
Figure 2 shows the pinouts for the SF1000 header locations.

Connections
Rabbit 2000 and Rabbit 3000 Boards
Serial Port B on all the Rabbit-based boards (except the BL2000 and the
BL2500) is the recommended port to use to connect the SF1000 serial flash
card. Table 2 lists the connections.
Refer to the user’s manual for you Rabbit-based single-board
computer for the locations of these connection pins.
While Serial Port B is the recommended port for connecting the SF1000
serial flash card, the programming port (Serial Port A), which is compatible
with the header pinout on header J1 on the SF1000, or a parallel I/O port
may also be used. A connector cable is available from Rabbit Semiconduc-
tor if you wish to connect the SF1000 to the programming port (Serial Port
A) on your Rabbit-based board.
Note that the programming port (Serial Port A) will not be
available for application development and debugging if it is
used to connect the SF1000 serial flash card.
Refer to the “Programming Information” section of the
“Software” chapter for details of the software associated with
your choice of connections.
The RCM3300 Prototyping Board, which can be used with RCM3000,
RCM3100, RCM3200, RCM3300/RCM3310, and RCM3360/RCM3370
RabbitCore modules, has a built-in header socket at J11 that allows an
SF1000 serial flash card to be plugged in directly to the Prototyping Board
to interface with Serial Port B on the RabbitCore module.

Asynchronous Serial Port B is not available on the BL2000, and so the
following parallel-port connections are recommended instead.
All three BL2000 outputs need to be pulled up to +5 V with a pull-up
resistor of 1 kΩ to 2 kΩ. The following additional modifications need to be
made.
• Remove R161 (removes GND from J9/J11 pin 12).
• Install R160 (adds VCC to J9/J11 pin 12).
• Remove C46, C47, and C48 (removes filter capacitors, which slow down
the output signals).
• Remove C31 (removes filter capacitor, which slows down the input
signal).

Only standard factory BL1700 models with digital inputs on
Bank A can be connected as shown since the SER_OUT signal
from the SF1000 must be connected to a digital input.
Note that a capacitor must be removed on the BL1700 as
indicated in Figure 5(d) to keep the SER_OUT signal from
getting slowed down too much by the capacitor.
Remove the high-voltage driver chip at U17 when using the
BL1700 with an SF1000. After you remove the chip, connect
jumper wires between pins 1–18, 2–17, and 3–16 of the socket
the high-voltage driver chip was plugged in to. This makes the
digital outputs TTL/CMOS compatible.

SOFTWARE
The SF1000 serial flash expansion card implements a flash memory chip
with a single, large, linear address space. It is up to the user to maintain
appropriate information within the program in order to store and retrieve
data in the flash memory.
The flash memory chip consists of a series of “sectors.” The size of each
sector is the same within a given chip, but can vary from one chip to
another. A sector also contains extra bytes that are not made available to
the user. Some of these bytes are used by the driver as follows:
• a fixed sync value, indicating that the sector has been written to at least
once,
• a version number, and
• a long integer value for the number of times the sector has been written.
The user should keep in mind that a flash memory chip has a limited
number of write cycles per sector, and that an entire sector must be written
at a time. The chips used in the SF1000 serial flash cards are specified at
50,000 write cycles typical. The most efficient usage dictates that the user
“block” all writing to the flash memory so that only full sectors are written.
More than one SF1000 serial flash card may be used in the control system
built around the Rabbit Semiconductor single-board computer. Users have
to write their own CS_enable/CS_disable functions to control the chip
select signals on the SF1000 serial flash cards. The only restriction is that all
the SF1000 serial flash cards have the same size of flash memory chip, i.e.,
4M or 8M.
SF100018
Dynamic C
Rabbit Semiconductor’s Dynamic C integrated development software is
used to add function calls from the SF1000.LIB or the SF1000_Z.LIB
library to your program. The SF1000.LIB library is available in Dynamic C
for Rabbit-based boards and the SF1000_Z.LIB library is available in DC
32 for selected Z180-based boards.
SF1000.LIB and SF1000_Z.LIB Library Functions
The following function calls are available in the Dynamic C SF1000.LIB
and in the SF1000_Z.LIB libraries. These functions are blocking func-
tions, but do not disable interrupts. The functions are not re-entrant.
• int SF1000Init ( void );
Minimum setup needed to verify correct flash operation.
PARAMETERS: None.

• int SF1000Write ( long FlashAddrDest,
void *SrcAddr, int ByteCount );
Write a block of data to the flash.
PARAMETERS:
FlashAddrDest is the data block’s initial address in the flash
SrcAddr is a pointer to the block’s source in root memory RAM
ByteCount is the number of bytes to write
RETURN VALUES:
0 = success
-1 = illegal byte count
-2 = illegal flash address

• int SF1000Read ( long FlashAddrSource,
void *DestAddr, int ByteCount );
Read a block of data from the flash.
PARAMETERS:
FlashAddrSource is the data block’s initial address in the flash
DestAddr is a pointer to the block’s destination in root memory
RAM
ByteCount is the number of bytes to read
RETURN VALUES:
0 = success
-1 = illegal byte count
-2 = illegal flash address
• long SF1000CheckWrites ( int Block );
Reads the number of times that a block has been written.
PARAMETER:
Block is the number of the flash block relative to 0 to check
RETURN VALUE: the number of times the block has been written.
• int SF1000EraseBlock ( int Block );
Erases a single block, including the sector prefix area, sync byte, library
software version number and sector writes count. The flash block's
previous prefix area information is lost permanently.
PARAMETER:
Block is the number of the flash block relative to 0 to check
RETURN VALUES:
0 = success
-1 = error reading device status
-2 = error erasing the block

Programming Information
Rabbit 2000 and Rabbit 3000 Boards
Define the following values before the #use SF1000.LIB statement.
1. Interface (default is SF1000_SER_B)
SPI
_
SER
_
A use Serial Port A
SPI
_
SER
_
B use Serial Port B
SPI
_
PARALLEL use a parallel I/O port
2. SPI bit rate (if using a serial port—default is 5)
SPI
_
CLK
_
DIVISOR
This is the divisor for the appropriate Timer A register.
3. I/O bit to be used for Chip Select (default is PB7)
SF1000_CS_PORT
SF1000_CS_PORTSHADOW
SF1000_CS_BIT
4. I/O bits for parallel interface
SPI
_
TX
_
REG register for clock and Tx data (default is PDDR)
SPI
_
TXD
_
BIT bit number for Tx data (default is bit 1)
SPI
_
CLK
_
BIT bit number for clock (default is bit 0)
SPI
_
RX
_
REG register for Rx data (default is PDDR)
SPI
_
RXD
_
MASK mask for Rx bit (default is 8, bit 3)
The default values will be used if SPI
_
TX
_
REG is not defined. If
SPI
_
TX
_
REG is defined, then all the values must be defined.
The transmit data and clock bits must be in the same register.
The I/O port must be initialized for proper operation of the
input and output!
If you are using the alternate Serial Port B I/O pins, you need
to define SERB
_
USEPORTD.
