P89LPC934FDH
Description
The P89LPC933/934/935/936 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 P89LPC933/934/935/936 in order to reduce ponent count, board space, and system cost.
Key Features
- 256-byte RAM data memory. Both the P89LPC935 and P89LPC936 also include a 512-byte auxiliary on-chip RAM
- 512-byte customer data EEPROM on chip allows serialization of devices, storage of setup parameters, etc. (P89LPC935/936)
- 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)
- 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
- Low voltage reset (brownout detect) allows a graceful system shutdown when power fails. May optionally be configured as an interrupt
- Oscillator fail detect. The watchdog timer has a sep
