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.
