General description
The P89LPC930/931 is a single-chip microcontroller designed for applications
demanding high-integration, low cost solutions over a wide range of performance
requirements. The P89LPC930/931 is 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 P89LPC930/931 in order to reduce component count, board space, and system
cost.

Features
I
A high performance 80C51 CPU provides instruction cycle times of 167-333 ns for
all instructions except multiply and divide when executing at 12 MHz. This is
6 times the performance of the standard 80C51 running at the same clock
frequency. A lower clock frequency for the same performance results in power
savings and reduced EMI.
I
2.4 V to 3.6 V V
DD
operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
I
4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size.
I
Byte-erase allowing code memory to be used for data storage.
I
Flash program operation completes in 2 ms.
I
Flash erase operation completes in 2 ms.
I
256-byte RAM data memory.
I
Two 16-bit counter/timers. Each timer may be configured to toggle a port output
upon timer overflow or to become a PWM output.
I
Real-Time clock that can also be used as a system timer.
I
Two analog comparators with selectable inputs and reference source.
I
Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities.
I
400 kHz byte-wide I
2
C-bus communication port.
I
SPI communication port.
I
Eight keypad interrupt inputs, plus two additional external interrupt inputs.
I
Four interrupt priority levels.
I
Watchdog timer with separate on-chip oscillator, requiring no external
components. The Watchdog time-out time is selectable from 8 values.
I
Active-LOW reset. On-chip power-on reset allows operation without external reset
components. A reset counter and reset glitch suppression circuitry prevent
spurious and incomplete resets. A software reset function is also available.
