P89LPC9201
Description
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.
Key Features
- 2.1 Principal features
- 256-byte RAM data memory
- 4-input multiplexed 8-bit ADC/single DAC output (P89LPC9241/9251). Two analog parators 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 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
- 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V)
- Enhanced low voltage (brownout) detect allows a graceful system shutdown when power fails
- Serial flash In-System Programming (ISP) allows coding while the device is mounted in the end application
- In-Application Programming (IAP) of the flash code memory. This allows changing the code in a running application
