P89LPC970/971/972  
8-bit microcontroller with accelerated two-clock 80C51 core  
2 kB/4 kB/8 kB wide-voltage byte-erasable flash  
Rev. 02 — 27 April 2010  
Product data sheet  
1. General description  
The P89LPC970/971/972 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 P89LPC970/971/972 in order to reduce component  
count, board space, and system cost.  
2. Features and benefits  
2.1 Principal features  
„ 2 kB/4 kB/8 kB byte-erasable flash code memory organized into 1 kB sectors and  
64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data  
storage.  
„ 256-byte RAM data memory.  
„ Two analog comparators with selectable inputs and reference source.  
„ Five 16-bit counter/timers (each 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 (pin remap).  
„ High-accuracy internal RC oscillator option 7.373 MHz calibrated to ±1 %, with clock  
doubler option, allows operation without external oscillator components. The RC  
oscillator option is selectable and fine tunable.  
„ Watchdog timer with separate on-chip oscillator, nominal 400 kHz/25 kHz, calibrated to  
±10 % at 400 kHz, requiring no external components. The watchdog prescaler is  
selectable from eight values.  
„ Pin remap for UART, I2C-bus and SPI.  
„ 2.4 V to 5.5 V VDD operating range.  
„ Enhanced low voltage (brownout) detect allows a graceful system shutdown when  
power fails.  
„ 20-pin TSSOP and DIP packages with 15 I/O pins minimum and up to 18 I/O pins  
while using on-chip oscillator and reset options.
