The P89LPC9201/9211/922A1/9241/9251 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 device in order to reduce component count, board sp.
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.
4-input multiplexed 8-bit ADC/single DAC output (P89LPC9241/9251). Two analog
comparators with selectable inputs and reference source.
On-chip temperature sensor integrated with ADC module (P89LPC9241/9251).
Two 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.
