SM5964A 8-Bit Micro-controller With 64KB ISP Flash & TWSI & PWM & 1KB RAM embedded Product List SM5964AL25, 25MHz 64KB internal flash MCU Feature z z z Working Voltage:3.0V through 3.6V 80C51 Central Processor Unit (CPU) 64K x 8 on chip flash memory with InSystem-Programming(ISP) capability and it can be programmed at VCC = 3.3V 1024 x 8 RAM, expandable externally to 64KB Two standard 16-bits timers/counters An additional 16-bits timer/counter coupled to a capture and compare register. Two 8-bits / 5-bits resolution Pulse-Width-Modulation (PWM) outputs Four 8-bits I/O ports.(For PDIP package) Four 8-bits I/O ports plus one 4-bits I/O port. (For PLCC or QFP package) TWSI-bus serial I/O port with master and slave functions Full-duplex UART 7 interrupt sources with 2 priority levels Temperature range (0℃ to +70℃) Software enable/disable ALE output pulse Wake-up from POWER-DOWN mode by external interrupt or H/W RESET. ISP service program space configurable in N*512 byte (N=0 to 8) size General Description The SM5964A is a single-chip 8-bits microcontroller manufactured in an advanced CMOS process with on chip flash memory. It supports InSystem 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...
