GENERAL DESCRIPTION
The P87LPC761 is a 16-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 P87LPC761 offers 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 P87LPC761 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 300–600ns for all instructions except multiply and divide when executing at 20 MHz. Execution at up to 20 MHz when VDD = 4.5 V to 6.0 V, 10 MHz when VDD = 2.7 V to 6.0 V
• 2.7 V to 6.0 V operating range for digital functions
• 2 kbytes EPROM code memory
• 128 byte RAM data memory
• 32-byte customer code EPROM allows serialization of devices, storage of setup parameters, etc
• Two 16-bit counter/timers. One timer may be configured to toggle a port output upon timer overflow
• Two analog comparators
• Full duplex UART
• I2C communication port
