P87LPC778  
CMOS single-chip 8-bit 80C51 microcontroller with  
128-byte data RAM, 8 kB OTP  
Rev. 01 — 31 March 2004  
Product data  
1. General description  
The P87LPC778 is a 20-pin single-chip microcontroller designed for low pin count  
applications demanding high-integration, low cost solutions over a wide range of  
performance requirements. A member of the Philips low pin count family, the  
P87LPC778 offers a 4 channel, 8-bit A/D converter, programmable oscillator  
configurations for high and low speed crystals or RC operation, wide operating  
voltage range, programmable port output configurations, selectable Schmitt trigger  
inputs, LED drive outputs, and a built-in Watchdog timer. The P87LPC778 is based  
on an accelerated 80C51 processor architecture that executes instructions at twice  
the rate of standard 80C51 devices.  
2. Features  
An accelerated 80C51 CPU provides instruction cycle times of 300 ns to 600 ns  
for all instructions except multiply and divide when executing at 20 MHz.  
2.7 V to 5.5 V operating range for digital functions.  
Four channel, 10-bit Pulse Width Modulator.  
Four channel, 8-bit Analog to Digital Converter. Conversion time is 9.3 µs with a  
20 MHz crystal.  
I2C-bus communication port and Full duplex UART.  
Internal oscillator 2.5 %. The internal oscillator option allows operation with no  
external oscillator components.  
Two analog comparators.  
Eight keypad interrupt inputs, plus two additional external interrupt inputs.  
Watchdog timer with separate on-chip oscillator, requiring no external  
components. The Watchdog time-out time is selectable from 8 values.  
20-pin TSSOP package.
