P87LPC778
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.
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 us with a 20 MHz crystal.
- I2C-bus communication port and Full duplex UART.
- Internal oscillator 2.5 pct. 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.
