Overview

The PIC16F13255-I/3LW is an 8-bit microcontroller based on the Enhanced Mid-Range PIC16 architecture, operating at up to 32MHz with 14KB of Flash memory. It features a rich set of Core Independent Peripherals (CIPs), including a Configurable Logic Block (CLB) and Configurable Logic Cells (CLC), which allow for hardware-level logic implementation without CPU overhead. This MCU is designed for low-power operation, featuring specialized sleep modes and a 256-byte EEPROM for non-volatile data storage.

Why Choose This Part

The inclusion of a Configurable Logic Block (CLB) allows for complex hardware-based state machines and logic gating that operates independently of the core. Its low-power performance is excellent, with sleep currents as low as 0.4uA and a power-optimized RISC architecture. The device offers a high degree of flexibility with 24 I/O pins and a wide array of communication peripherals in a compact 4x4mm VQFN package.

Applications

Custom Logic Integration
Utilizing the Configurable Logic Block (CLB) and CLC to replace external discrete logic components or offload timing-critical tasks from the CPU.
Sensor Interface
Interfacing with analog sensors using the integrated 10-bit ADC, 10-bit DAC, and Fixed Voltage Reference (FVR) for precise measurements.
Industrial Control
Implementing small-scale industrial automation tasks using LINbus, I2C, and SPI connectivity alongside hardware PWM and CCP modules.
Battery-Powered Devices
Taking advantage of the ultra-low sleep current and power-saving modes like Doze and Idle for extended battery life in portable applications.
