1.1 General Description

The M6759 is an 8032/8052 instruction compatible

8-bit microcontroller 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. Furthermore, user-defined security

registers can protect the firmware after the code is

ready.

The 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.
