General description

The P89LPC9151/9161/9171 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 device in order to reduce component count,

board space, and system cost.

Features

2.1 Principal features

2 kB byte-erasable flash code memory organized into 256-byte sectors and 16-byte

pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.

256-byte RAM data memory.

4-input multiplexed 8-bit ADC/single DAC output. Two analog comparators with

selectable inputs and reference source.

Two 16-bit counter/timers. Timer 0 (and Timer 1 - P89LPC9171) 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 (P89LPC9161).

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).

Enhanced low voltage (brownout) detect allows a graceful system shutdown when

power fails.

16-pin TSSOP with 12 I/O pins minimum and up to 14 I/O pins while using on-chip

oscillator and reset options (P89LPC9161/9171), and 14-pin TSSOP packages with 10

I/O pins minimum and up to 12 I/O pins while using on-chip oscillator and reset options

(P89LPC9151).
