Product List
SM89S16R1L25, 25MHz 64KB internal flash MCU
Feature
SM89S16R1C25, 25MHz 64KB internal flash MCU
SM89S16R1C40, 40MHz 64KB internal flash MCU
z Working Voltage: 3.3V or 5.0V.
z 80C51 Central Processor Unit (CPU).
General Description
The SM89S16R1 is a single-chip 8-bits micro-
z 64K x 8 bits on chip flash memory.
z 1024 x 8 bits RAM, expandable externally to
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
64KB.
z Two standard 16-bits timers/counters
z An additional 16-bits timer/counter coupled to
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
a capture and compare register.
z Two 8-bits / 5-bits resolution
Pulse-Width-Modulation (PWM) outputs
z Four 8-bits I/O ports.(For PDIP package)
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
z Four 8-bits I/O ports plus one 4-bits I/O port.
(For PLCC or QFP package)
z Full-duplex UART
extra capability the SM89S16R1 can be expanded
using standard TTL and LVTTL compatible
memory and logic.
In addition, The SM89S16R1 has two software
z 8 interrupt sources with 2 priority levels
z Extended temperature range (-40℃ to +85℃)
z Software enable/disable ALE output pulse
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
z Wake-up from POWER-DOWN mode by
INT0/INT1, RTCI or H/W RESET.
z RTC (Real Time Clock) function.
z Four channels 6-bits Analog to Digital
RAM contents but freezes the oscillator, causing all
other chip functions to be inoperative.
Converter (ADC).
