General Description
The SM89S16R1 is a single-chip 8-bits micro- controller
manufactured in an advanced CMOS process with on chip
flash memory. It supports a derivative of the 80C51
microcontroller family. The SM89S16R1 has the same
instructions set as the 80C51.
The SM89S16R1 contains a 64K x 8 bits on chip program
flash, a volatile 1024 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
PWM clock outputs, one serial interfaces (UART bus). For
system that requires extra capability the SM89S16R1 can be
expanded using standard TTL and LVTTL compatible
memory and logic.
In addition, The SM89S16R1 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.
