P89LPC921 Product details

Description

The P89LPC920/921/922 are single-chip microcontrollers designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements.

Features

2.1 Principal features s 2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable page size, and single byte erase. s 256-byte RAM data memory. s Two 16-bit counter/timers. Each timer may be conﬁgured to toggle a port output upon timer overﬂow or to become a PWM output. s Real-Time clock that can also be used as a system timer. s Two analog comparators with selectable inputs and reference source. s Enhanced UART with fractional baud rate generator, break detect, framing erro.
