SM89T16R1 8-Bits Micro-controller With 64KB Flash ROM & IKB RAM & Two UART & RTC & ADC & PWM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. SM89T16R1 V1.0 JANUARY 2005 1 Product List SM89T16R1L16, 16MHz 64KB internal flash MCU SM89T16R1C25, 25MHz 64KB internal flash MCU General Description The SM89T16R1 is a high speed (4 clocks / machine cycle) single-chip 8-bits microcontroller manufactured in an advanced CMOS process with on chip flash memory. It supports a derivative of the 80C51 microcontroller family. The SM89T16R1 has the same instructions set as the 80C51. The SM89T16R1 contains a 64KB on chip program flash, a volatile 1280 x 8 bits 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 outputs, two UART and two DPTR, an on-chip oscillator and timing circuit. For system that requires extra capability the SM89T16R1 can be expanded using standard TTL compatible memory and logic. In addition, The SM89T16R1 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 Power Management Mode (PMM) is useful for portable or battery-powered applications. This feature allows software to select a lower speed clock as the main time base.
