Rev. 08 — 15 December 2004
Product data
1. General description
The P89LPC920/921/922/9221 are single-chip microcontrollers designed for
applications demanding high-integration, low cost solutions over a wide range of
performance requirements. The P89LPC920/921/922/9221 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 P89LPC920/921/922/9221 in order to reduce component count,
board space, and system cost.
2. Features
2.1 Principal features
s 2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable
page size, and single byte erase.
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 Configurable on-chip oscillator with frequency range and RC oscillator options
(selected by user programmed Flash configuration bits). The RC oscillator (factory
calibrated to ±1 %) option allows operation without external oscillator
components. Oscillator options support frequencies from 20 kHz to the maximum
operating frequency of 18 MHz. The RC oscillator option is selectable and fine
tunable.
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 High drive current (20 mA) on eight I/O pins on the P89LPC9221 (P0.3 to P0.7,
P1.4, P1.6, P1.7).
