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.
