SM5964A 8-Bit Micro-controller With 64KB ISP Flash & TWSI & PWM & 1KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.3 SM5964A 10/2006 1 Product List SM5964AL25, 25MHz 64KB internal flash MCU General Description The SM5964A is a single-chip 8-bits micro- controller manufactured in an advanced CMOS process with on chip flash memory. It supports In- System Programming (ISP) function and is a derivative of the 8052 microcontroller family. The SM5964A has the same instructions set as the 80C51. The SM5964A contains a 64KB 3.3V on chip program flash, a volatile 1024 x 8 data RAM, four 8-bits I/O ports, one 4-bits I/O port, two 16-bits timer/event counters, and an additional 16-bits timer coupled to capture and compare latches, a two-priority-level, nested interrupt structure, two pulse-width- modulation (PWM) outputs, two serial interfaces (UART and TWSI bus). For system that requires extra capability the SM5964A can be expanded using standard LVTTL compatible memory and logic. In addition, The SM5964A has two software selectable modes of power saving – IDLE mode and POWER-DOWN mode. The IDLE mode freezes the CPU while allowing the RAM, timer, serial ports, and interrupt system to continue functioning. The POWER-DOWN mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative. The SM5964A is designed for 3.3V applications. The on chip flash memory can store data while the program is running. It also can upgrade the user program by down-load new code form PC or other devices. The chip is considered as a small integrated system.
