PIC16C55-LPI/P Equivalent & Substitute Parts Reference

Part Overview

The PIC16C55-LPI/P is an 8-bit microcontroller from Microchip Technology within the PIC® 16C series. It offers 768B (512 x 12) of OTP program memory, operates at speeds up to 40MHz, and is housed in a 28-pin PDIP package. The part accommodates applications requiring up to 20 I/O and operates within a voltage range of 2.5V to 6.25V. The device is currently active and compliant with RoHS3 and REACH environmental standards. In situations where the PIC16C55-LPI/P is unavailable or a different memory type is required, it is necessary to identify alternative models with equivalent electrical, mechanical, and compliance characteristics.
