P87LPC779
CMOS single-chip 8-bit 80C51 microcontroller with
128-byte data RAM, 8 kB OTP
Rev. 02 鈥?03 May 2004
Product data
1. General description
The P87LPC779 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
P87LPC779 offers a four channel, 8-bit A/D converter, two DAC outputs,
programmable oscillator con鏗乬urations for high and low speed crystals or RC
operation, wide operating voltage range, programmable port output con鏗乬urations,
selectable Schmitt trigger inputs, LED drive outputs, and a built-in Watchdog timer.
The P87LPC779 is based on an accelerated 80C51 processor architecture that
executes instructions at twice the rate of standard 80C51 devices.
2. Features
s
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.
