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.
Features
- 2.1 Principal features.
- 2 kB/4 kB/8 kB byte-erasable flash code memory organized into 1 kB 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 comparators 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 become a PWM output).
- A 23-bit system timer that can also.
