General Description
The M6759 is an 8032/8052 instruction compatible 8-
bit micro-controller with MTP Flash ROM for firmware
updating. By combining a versatile 8-bit CPU with
MTP-Flash, this device provides whole micro-
controller 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.

Description
Power supply for internal operation, 5V input.
Ground.
Port 0 is 8 bits bi-directional I/O port with internal pull high.
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.
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.
Crystal In, can be used as external clock input.
Crystal out, feedback of XTAL1.
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.
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.
Port 1 is 8 bits bi-directional I/O port with internal pull high. All pins have an
alternate function shown as below.
External timer/counter 2 trigger.
External timer/counter 2.
Port 2 is 8 bits bi-directional I/O port with internal pull high. The alternate
function is MSB 8 bit address bus
This bus emits the high-order address byte during fetches from external
Program Memory or during accesses to external Data Memory that use 16-
bit 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.
Port 3 is an 8-bit bi-directional I/O port with internal pull high. The reset
condition of this port is with all bits at a logic 1.
Port 3 also have alternate function list below
External data memory read strobe.
External data memory write strobe.
External timer/counter 1.
External timer/counter 0.
External interrupt 1 (Negative Edge Detect).
External interrupt 0 (Negative Edge Detect).
Serial port output.
Serial port input.
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.
These pins should not be connected for any purpose
