Description

PIC16F628A-I/P 3.5KB 3V~5.5V PIC 224Byte 20MHz FLASH 16 PDIP-18 Microcontroller Unit The PIC16F628A-I/P 3.5KB 3V~5.5V PIC 224Byte 20MHz FLASH 16 PDIP-18 Microcontroller Unit is a high-performance, yet power-efficient, 8-bit microcontroller from Microchip’s widely adopted mid-range PIC® family. Utilizing advanced CMOS FLASH technology and offered in a through-hole 18-pin Dual In-line Package (PDIP) , this device is explicitly designed for industrial, educational, and general-purpose embedded applications where a balance of robustness, functionality, and cost-effectiveness is critical. The core architecture is optimized for execution speed, employing a sophisticated, reduced instruction set (RISC) that supports efficient control and data processing tasks. The architecture permits clock frequencies up to 20MHz, which translates to an execution speed of up to 5 Millions of Instructions Per Second (MIPS), providing substantial processing capability for a wide array of time-sensitive embedded systems. Features: PIC16F628A-I/P High-performance Mid-Range 8-bit RISC CPU architecture with 35 single-word instructions. Maximum clock speed of 20MHz, translating to an execution speed of 5 MIPS. Integrated 3.5KB FLASH Program Memory for reliable firmware storage. Non-volatile 128 bytes of data EEPROM for persistent data storage. 224 bytes of high-speed Data SRAM.
