M6759: 8 bit MTP Micro-controller --Proprietary, Confidential, Preliminary-- Product Brief M6759 : 8 Bit MTP Micro-controller Features l 8051 instruction set compatible 8 bit micro- controller l 8051/8052 compatible pin out l Complete static design, wide range of operation frequency from 1 ~ 40 MHz l Large on-chip memory ² 64K bytes build-in Multiple Times Programming ROM (MTP-ROM) program memory ² 512 bytes on-chip SRAM, expandable external 64K bytes address space l Four 8-bit bi-directional I/O ports l 13 interrupts including 6 external source l One full-duplex serial UART ports compatible with standard 8052 l Two 16 bit timer/counter l One 16 bit timer l On chip oscillator for crystal l Software power-down mode, support IDLE mode and STOP mode for less power consumption l ROM Code Protection l 4.5V~5.5V operation voltage, 12V programming l 44 pin PLCC or QFP package 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.
