PIC18C252-I/SP

These device PIC18C252 come in 28-pin and 40-pin packages. The 28-pin devices do not have a Parallel Slave Port (PSP) implemented and the number of Analog-toDigital (A/D) converter input channels is reduced to 5.

• 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 interrupt on Address bit
• Parallel Slave Port (PSP) module Pin Diagrams A
