GENERAL DESCRIPTION
The P87LPC764 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 P87LPC764 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
P87LPC764 is based on an accelerated 80C51 processor
architecture that

供应NXP P89LPC922 单片机
信息内容：The P89LPC920/921/922/9221 are single-chip microcontrollers designed forapplications demanding high-integration, low cost solutions over a wide range ofperformance requirements. The P89LPC920/921/922/9221 is based on a highperformance processor architecture that executes instructions in two to four clocks,six times the rate of standard 80C51 devices. Many system-level functions have beenincorporated into the P89LPC920/921/922/9221 in order to reduce component count,board space, and system cost. 2.1 Principal featuresn 2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasablepage size, and single byte erase.n 256-byte RAM data memory.n Two 16-bit counter/timers. Each timer may be configured to toggle a port outputupon timer overflow or to become a PWM output.n Real-Time clock that can also be used as a system timer.n Two analog comparators with selectable inputs and reference source.n Enhanced UART with fractional baud rate generator, break detect, framing error...
