General Description
The M6759 is an 8032/8052 instruction compatible 8bit micro-controller with MTP Flash ROM for firmware updating. By combining a versatile 8-bit CPU with MTP-Flash, this device provides whole microcontroller system on one chip and still remains the feasibility for general control systems in a variety of applications. Further more, the firmware can be protected by user-defined security registers after the code is ready. ALi M6759 contains the following: a) a non-volatile 64K bytes Multiple Times Programmable ROM program memory. b) a volatile 512 bytes read/write data memory c) four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51). d) a 16-bit timer (identical to the Timer 2 of the 8052). e) a multi-source two-priority-level nested interrupt structure. f) one serial interface (UART) and g) an on-chip oscillator.

Pin Description
Pin assignments shown below are listed based on 44-pin PLCC package. And if not additionally specified, further pin number reference throughout this document is, by default, referred to 44-pin PLCC package. As for QFP package, the pin number assignment should be shifted accordingly, as shown in Pinout Configuration. Pin Name VDD GND P0.7-P0.0 No. (PLCC) Type Description 44 IN Power supply for internal operation, 5V input. 22 IN Ground. 36,37,38,39, I/O Port 0 is 8 bits bi-directional I/O port with internal pull high. 40,41,42, 43 AD7-0 Multiplexed address/data bus. During the time when ALE is high, the LSB of a memory address is presented. When ALE falls, the port transitions to a bi-directional data bus. This bus is used to read external ROM and read/write external RAM memory or peripherals. RST 10 IN Reset signal of internal circuit, it must be kept 4 clocks to ensure being recognized by internal circuit. This signal will not affect internal SRAM. XTAL1 21 IN Crystal In, can be used as external clock input. XTAL2 20 OUT Crystal out, feedback of XTAL1. /PSEN 32 OUT Program Store Enable Output, commonly connected to external ROM memory as a chip enable during fetching and MOVC operation. /PSEN goes high during a reset condition. ALE 33 OUT Address Latch Enable, used to latch external LSB 8 bit address bus from multiplexed address/data bus, commonly connect to the latch enable of 373 family. This signal will be forced high when the device is in a reset condition. P1.7-P1.0 9,8,7,6,5,4,3, I/O Port 1 is 8 bits bi-directional I/O port with internal pull high. All pins have an 2 alternate function shown as below. T2EX (P1.1) IN External timer/counter 2 trigger. T2 (P1.0) IN External timer/counter 2. P2.7-P2.0 31,30,29,28, I/O Port 2 is 8 bits bi-directional I/O port with internal pull high. The alternate 27,26,25, 24 function is MSB 8 bit address bus A15-A8 OUT This bus emits the high-order address byte during fetches from external Program Memory or during accesses to external Data Memory that use 16bit addresses (MOVX @ DPTR). During accesses to external Data Memory that use 8-bit addresses (MOVX @ Ri), Port 2 emits the contents of the P2 Special Function Register. P3.7-P3.0 19,18,17,16, I/O Port 3 is an 8-bit bi-directional I/O port with internal pull high. The reset 15,14,13, 11 condition of this port is with all bits at a logic 1. Port 3 also have alternate function list below /RD (P3.7) OUT External data memory read strobe. /WR (P3.6) OUT External data memory write strobe. T1 (P3.5) IN External timer/counter 1. T0 (P3.4) IN External timer/counter 0. /INT1 (P3.3) IN External interrupt 1 (Negative Edge Detect). /INT0 (P3.2) IN External interrupt 0 (Negative Edge Detect). TXD (P3.1) OUT Serial port output. RXD (P3.0) IN Serial port input. /EAVPP 35 IN The pin must be externally held low to enable the device to fetch code from external program memory. If /EAVPP is held high, the device executes from internal program memory. /EAVPP is internal latched on reset. This pin also receives the 12V programming voltage (VPP) during FLASH programming. NC 1,12,23,34 NC These pins should not be connected for any purpose
