Descriptions:

The PIC16C55-XT/P is an 8-bit microcontroller based on Microchip’s PIC architecture. It features a 12-bit instruction set and is designed for low-power, cost-sensitive applications. The device is OTP-based, meaning the program memory can be written only once. It operates at a maximum speed of 5 MIPS and includes basic peripherals such as I/O ports and an 8-bit timer.

Features:

• Low-power consumption
• High-performance RISC CPU
• Only 33 single-word instructions
• 12-bit wide instructions
• 8-bit timer with prescaler
• Power-on Reset (POR)
• Watchdog Timer (WDT)
• Wide operating voltage range (2.5V–6.25V)
• Industrial temperature range (-40°C to +85°C)

This microcontroller is commonly used in simple control applications, embedded systems, and consumer electronics where low cost and basic functionality are required.
