The 8-bit CMOS EPROM microcontroller integrates a multichannel analog-to-digital converter in the PIC16CXX mid-range architecture. It provides 4096 x 14 words of program memory, 192 bytes of user RAM, and up to 5 MIPS performance at a 20 MHz clock. The core uses 35 single-word instructions, an eight-level hardware stack, separate instruction and data buses, and direct, indirect, and relative addressing modes. Peripheral functions include Timer0, Timer1, Timer2, capture/compare/PWM support, SSP for SPI and I2C, and a USART/SCI serial interface. The device supports a 2.5 V to 6.0 V operating range, sleep mode, watchdog timer, oscillator options, and 25 mA sink/source drive capability.
