PIC16F887-I/P

Datasheet

  • Factory calibrated to ±1%
  • Software selectable frequency range of 8 MHz to 32 kHz
  • Software tunable
  • Two-Speed Start-Up mode
  • Fail-safe clock monitoring for critical applications
  • Clock mode switching during operation for low-power operation

This powerful yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip’s powerful PIC® architecture into an 40- or 44-pin package.The PIC16F887 features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 14 channels of 10-bit Analog-to-Digital (A/D) converter, 1 capture/compare/PWM and 1 Enhanced capture/compare/PWM functions, a synchronous serial port that can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and an Enhanced Universal Asynchronous Receiver Transmitter (EUSART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances or consumer applications.
