P89LPC920/921/922  
8-bit microcontrollers with two-clock 80C51 core  
2 kB/4 kB/8 kB 3 V low-power Flash with 256-byte data RAM  
Rev. 06 — 21 November 2003  
Product data  
1. General description  
The P89LPC920/921/922 are single-chip microcontrollers designed for applications  
demanding high-integration, low cost solutions over a wide range of performance  
requirements. The P89LPC920/921/922 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 in order to reduce component count, board space, and  
system cost.  
2. Features  
2.1 Principal features  
■ 2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable  
page size, and single byte erase.  
■ 256-byte RAM data memory.  
■ Two 16-bit counter/timers. Each timer may be configured to toggle a port output  
upon timer overflow or to become a PWM output.  
■ Real-Time clock that can also be used as a system timer.  
■ Two analog comparators with selectable inputs and reference source.  
■ Enhanced UART with fractional baud rate generator, break detect, framing error  
detection, automatic address detection and versatile interrupt capabilities.  
■ 400 kHz byte-wide I2C-bus communication port.  
■ Configurable on-chip oscillator with frequency range and RC oscillator options  
(selected by user programmed Flash configuration bits). The RC oscillator option  
allows operation without external oscillator components. Oscillator options  
support frequencies from 20 kHz to the maximum operating frequency of 12 MHz.  
The RC oscillator option is selectable and fine tunable.  
■ 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).  
■ 15 I/O pins minimum. Up to 18 I/O pins while using on-chip oscillator and reset  
options.  
2.2 Additional features  
■ 20-pin TSSOP and DIP packages.  
■ A high performance 80C51 CPU provides instruction cycle times of 167 ns to  
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.
