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 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.
