1. 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.
2. Features
s 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.
s 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
s 4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size.
s Byte-erase allowing code memory to be used for data storage.
s Flash program operation completes in 2 ms.
s Flash erase operation completes in 2 ms.
s 256-byte RAM data memory.
s Two 16-bit counter/timers. Each timer may be configured to toggle a port output
upon timer overflow or to become a PWM output.
s Real-Time clock that can also be used as a system timer.
s Two analog comparators with selectable inputs and reference source.
s Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities.
s 400 kHz byte-wide I2C-bus communication port.
s SPI communication port.
s Eight keypad interrupt inputs, plus two additional external interrupt inputs.
s Four interrupt priority levels.
s Watchdog timer with separate on-chip oscillator, requiring no external
components. The Watchdog time-out time is selectable from 8 values.
s 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.

7. Special function registers
Remark: Special Function Registers (SFRs) accesses are restricted in the following
ways:
• User must not attempt to access any SFR locations not defined.
• Accesses to any defined SFR locations must be strictly for the functions for the
SFRs.
• SFR bits labeled ‘-’, ‘0’ or ‘1’ can only be written and read as follows:
– ‘-’ Unless otherwise specified, must be written with ‘0’, but can return any value
when read (even if it was written with ‘0’). It is a reserved bit and may be used in
future derivatives.
– ‘0’ must be written with ‘0’, and will return a ‘0’ when read.
– ‘1’ must be written with ‘1’, and will return a ‘1’ when read.
