The PIC12C67X devices are low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers with integrated analog-to-digital (A/D) converter and EEPROM data memory (EEPROM on PIC12CE67X versions only). All PIC® microcontrollers employ an advanced RISC architecture. The PIC12C67X microcontrollers have enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches, which require two cycles. A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance.

The PIC18F26K20 is a 28/40/44-Pin Flash Microcontrollers with XLP Technology. The following are the features:- • Up to 35 I/O Pins plus 1 Input-only Pin: - High-Current Sink/Source 25 mA/25 mA - Three programmable external interrupts - Four programmable interrupt-on-change - Eight programmable weak pull-ups - Programmable slew rate • Capture/Compare/PWM (CCP) Module • Enhanced CCP (ECCP) module: - One, two or four PWM outputs - Selectable polarity - Programmable dead time - Auto-shutdown and auto-restart
