Features

* High current sink/source 25 mA/25 mA
* Three external interrupt pins
* Timer0 module: 8-bit/16-bit timer/counter with 8-bit programmable prescaler
* Timer1 module: 16-bit timer/counter
* Timer2 module: 8-bit timer/counter with 8-bit period register (time-base for PWM)
* Timer3 module: 16-bit timer/counter
* Secondary oscillator clock option – Timer1/Timer3
* Two Capture/Compare/PWM (CCP) modules. CCP pins that can be configured as:
– Capture input: capture is 16-bit, max. resolution 6.25 ns (TCY/16)
– Compare is 16-bit, max. resolution 100 ns (TCY)
– PWM output: PWM resolution is 1- to 10-bit, max. PWM freq. @: 8-bit resolution = 156 kHz 10-bit resolution = 39 kHz
* Master Synchronous Serial Port (MSSP) module, Two modes of operation:
– 3-wire SPI (supports all 4 SPI modes)
– I2C Master and Slave mode
* Addressable USART module:
– Supports RS-485 and RS-232
