Electrical and Environmental Specifications

Operating Characteristics

Electrical Operating Characteristics

Power supply Nominal 5.00 V

Minimum 4.75 V

Maximum 5.25 V

Power consumption Typical <6 W

Backup Battery Characteristics

There is no configuration data saved by the BIOS for the CMOS Real Time Clock. Therefore, the CPU module does not

need a battery except for applications that need to retain date and time data at power-off.

Battery Voltage Nominal 3.6 V

Minimum 3.0 V

Maximum 3.9 V

Note:

Setup data is stored in the BIOS Flash EPROM; it is therefore impossible to lose the setup

data due to a lack of power.

Operating Temperature Range

For correct operation of the module, the ambient air temperature must remain within the following range:

Standard Minimum +0 °C

Maximum +60 °C

Extended Minimum -40 °C

Maximum +85 °C

Absolute Maximum Ratings

Supply Voltage Minimum 0.00 V

Maximum 5.25 V

Storage Temperature Range Minimum -40 °C

Maximum +85 °C

Non-Condensing Relative Humidity <95% at 40°C

Warning:

Stressing the module beyond the “Absolute Maximum Ratings” may cause permanent damage.

These are stress ratings only. Operation beyond the “Operating Conditions” is not recommended.

Extended exposure beyond the “Operating Conditions” may affect device reliability

How to connect the CPU-1433 with other PC/104 & PC/104-Plus

devices: the stack assembly

The ISA and PCI bus connectors of the module are designed to allow it to be connected with other PC/104 and/or

PC/104-Plus devices, we recommend users to follow this procedure to ensure that stacked modules are not damaged.

Warning:

Appropriate ESD (Electro Static Discharge) precautions should be used for the following

procedure.

1. Turn off the power to the PC/104 (or PC/104-Plus) system or stack.

2. Select and install standoffs as required to correctly position the module on the PC/104 stack.

3. Remove the module from its anti-static bag.

4. Check that keying pins in the bus connector are correctly positioned.

5. Check the stacking order; make sure an XT bus card will not be placed between two AT bus cards or it will

interrupt the AT bus signals.

6. Hold the module by its edges and orient it so that the bus connector pins line up with the matching connector on

the stack.

7. Press the module evenly onto the PC/104 stack.

Figure 4 shows a typical module stack with two PC/104 modules, one PC/104 1

6-BIT module, and one PC/104 8-BIT

module.

The maximum number of modules is four in addition to the Host Board.

Figure 4. The Module Stack

Warning:

Do not force the module onto the stack! Wiggling the module or applying too much pressure may

damage it. If the module does not readily press into place, remove it, check for bent pins or out-of-

place keying pins, and try again.

J1 and J2: the ISA Bus

Connectors J1 and J2 carry the signals for the ISA Bus.

These signals match the definitions of the IEEE P996 standard.

Figure 5. ISA BUS layout

According to the PC/104 specifications, these connectors include KEY pins; these are filled holes in the upper side and

missing pins in the lower side of the bus. This is done to avoid the wrong insertion in/of another module.

Note:

If the Serial port is used in RS485 mode, the bi-directional line must be controlled via

software, using the Data Terminal Ready (DTR) signal of the serial controller.

This signal is defined by bit 0 of the UART Modem Control Register (MCR) and the bi-

directional line is controlled as follows:

• Bit 0 of the MCR register = 0 means RS485 line receiving

• Bit 0 of the MCR register = 1 means RS485 line transmitting

The I/O address of the MCR is "Serial port Base address" +4H.
