P89LPC970
description
The P89LPC970/971/972 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC970/971/972 in order to reduce ponent count, board space, and system cost.
2. Features and benefits
2.1 Principal features
- 2 k B/4 k B/8 k B byte-erasable flash code memory organized into 1 k B sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
- 256-byte RAM data memory.
- Two analog parators with selectable inputs and reference source.
- Five 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or to bee a PWM output).
- A 23-bit system timer that can also be used as real-time clock consisting of a 7-bit prescaler and a programmable and readable 16-bit timer.
- Enhanced UART with a...
