Microchip PIC16F628-04/P 8-bit Flash Microcontroller, DIP18

The Microchip PIC16F628-04/P is an 8-bit fully-static Flash-based CMOS microcontroller from the high-performance PIC16F62X family. This advanced device features an enhanced core with an eight-level deep stack and multiple internal and external interrupt sources, enabling robust and responsive control for a wide range of applications.

Utilising a Harvard architecture with separate instruction and data buses, it allows a 14-bit wide instruction word alongside an 8-bit wide data path. The two-stage instruction pipeline ensures most instructions execute in a single cycle, significantly boosting processing efficiency. With a total of 35 instructions in its reduced instruction set and a large register set, this microcontroller delivers superior performance, typically achieving a 2:1 code compression and a 4:1 speed improvement over comparable 8-bit microcontrollers.

Designed for reliability and low power consumption, the PIC16F628 integrates several special features to minimise external components. These include a 128-byte EEPROM data memory, programmable weak pull-ups on Port-B, a watchdog timer with its own on-chip RC oscillator, and both power-up and oscillator start-up timers. It supports In-Circuit Serial Programming™ (ICSP) via just two pins for easy updates and features low-voltage programming capability.

This component is built to operate in demanding environments, with an industrial and extended temperature range. It is ideal for power management systems and sensing instrumentation. Please note: this is an ESD-sensitive device; proper handling precautions are essential.
