General description
The P89LPC970/971/972 is a single-chip microcontroller, available in low cost packages,
based on a high performance processor architecture that executes instructions in two to
four clocks, six times the rate of standard 80C51 devices. Many system-level functions
have been incorporated into the P89LPC970/971/972 in order to reduce component
count, board space, and system cost.

Features and benefits
2.1 Principal features
2 kB/4 kB/8 kB byte-erasable flash code memory organized into 1 kB sectors and
64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data
storage.
256-byte RAM data memory.
Two analog comparators with selectable inputs and reference source.
Five 16-bit counter/timers (each may be configured to toggle a port output upon timer
overflow or to become a PWM output).
A 23-bit system timer that can also be used as real-time clock consisting of a 7-bit
prescaler and a programmable and readable 16-bit timer.
Enhanced UART with a fractional baud rate generator, break detect, framing error
detection, and automatic address detection; 400 kHz byte-wide I2C-bus
communication port.
SPI communication port (pin remap).
High-accuracy internal RC oscillator option 7.373 MHz calibrated to
±1 %, with clock
doubler option, allows operation without external oscillator components. The RC
oscillator option is selectable and fine tunable.
Watchdog timer with separate on-chip oscillator, nominal 400 kHz/25 kHz, calibrated to
±10 % at 400 kHz, requiring no external components. The watchdog prescaler is
selectable from eight values.
Pin remap for UART, I2C-bus and SPI.
2.4 V to 5.5 V VDD operating range.
Enhanced low voltage (brownout) detect allows a graceful system shutdown when
power fails.
20-pin TSSOP and DIP packages with 15 I/O pins minimum and up to 18 I/O pins
while using on-chip oscillator and reset options.
