NUTINY-ML51EB USER MANUAL
1 OVERVIEW
NuTiny-ML51EB is the specific development tool for 8-bit high performance 1T 8051-based
microcontroller ML51 16K Flash size series. User can use NuTiny-ML51EB to develop and verify
the application program easily.
The ML51 runs up to 24 MHz at a wide voltage range from 1.8V to 5.5V, and contains up to
64/32/16/8 Kbytes Flash called APROM for programming code. The ML51 Flash supports In-
Application-Programming (IAP) function, which enables on-chip firmware updates. Partial Flash
can be optionally configured as Data Flash programmed by IAP and read by IAP or MOVC
instruction. The ML51 includes an additional configurable up to 4/3/2/1 Kbytes Flash area called
LDROM, in which the Boot Code normally resides for carrying out the In-System-Programming
(ISP). To facilitate mass production programming and verification, the Flash is allowed to be
programmed and read electronically by parallel Writer/Programmer or In-Circuit-Programming
(ICP) with Nu-Link. Once programmed and verified, the programmed code can be protected by
the Flash lock mechanism for not being read out by any external programming tool.
The ML51 provides rich peripherals including 256 bytes of SRAM, 4/2/1 Kbytes of auxiliary RAM
(XRAM), up to 43 general purpose I/O, two 16-bit Timers/Counters 0/1, one 16-bit Timer2 with
three-channel input capture module, one Watchdog Timer (WDT), one Self Wake-up Timer
(WKT), one 16-bit auto-reload Timer3 for general purpose or baud rate generator, two UARTs
with frame error detection and automatic address recognition, two ISO7816 Smartcard interface,
two SPI, two I
2
C, 12 enhanced PWM output channels with dead zone control, two analog
comparators, eight-channel shared pin interrupt for all I/O ports, and one 12-bit ADC at 500 ksps.
There are a total of 30 sources with 4-level-priority interrupts capability.
The ML51 is equipped with four clock sources and supports on-the-fly clock switching via
software control. The four clock sources include two sets of external crystal inputs (HXT, LXT),
38.4 kHz internal oscillator, and one 24 MHz internal high-precision ±2% oscillator. The ML51
provides additional power monitoring detection such as power-on reset and 7-level brown-out
detection, which stabilizes the power-on/off sequence for a high reliability system design.
Through the high performance of 1T 8051 core, low power performance of ML51 and rich well-
designed peripherals, the ML51 benefits for low-power, battery powered devices, general
purpose, home appliances, or motor control system.

NUTINY-ML51EB USER MANUAL
2 NUTINY-ML51EB INTRODUCTION
NuTiny-ML51EB uses the ML51EB9AE as the target microcontroller. Figure 2.1-1 is NuTiny-
ML51EB for the ML51 16K Flash size series, the left portion is called NuTiny-EVB-ML51 and the
right portion is Debug Adaptor called Nu-Link-Me.
NuTiny-EVB-ML51 is similar to other development boards. User can use it to develop and verify
applications to emulate the real behavior. The on-board chip covers ML51 series features. The
NuTiny-EVB-ML51 can be a real system controller to design user’s target systems.
Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC's USB port to
the user’s target system (via Serial Wired Debug Port) and allows user to program and debug
embedded programs on the target hardware. To use Nu-Link-Me Debug adaptor with Keil
,
please
refer to “Nuvoton Nu-Link debug adapter user manual” in detail. This document will be stored in
the local hard disk when user installs each driver. Nu-Link-Me also supports virtual COM port
function. User can use Nu-Link-Me as a USB to UART virtual COM port, which connects to on-
board ML51EB9AE UART0.

Virtual COM Port Switch Description 2.1
The switch in Nu-Link-Me, SW3, determines that the virtual COM port function is enabled or
disabled. When user turns on all of the positions of switch, the virtual COM port function will be
enabled. By using virtual COM port function, user can access the USB device in the same way as
it would access a standard COM port to ML51EB9AE UART0 (P3.1 and P3.0) . To use this
function, user needs to install “VCOM Driver” at first. User can get “Nuvoton USB driver” from
NuMicroDVD www.nuvoton.com\NuMicroDVD in folder “Software Utilities” or from website:
