PIC16F1516-E/SS

Updated: 2026-09-11

Overview

The PIC16F1516-E/SS is part of Microchip's PIC16F family, designed for embedded control applications requiring low power and high integration. It combines an 8-bit RISC CPU core with 14 KB of Flash memory, enabling flexible firmware updates. The MCU operates at up to 32 MHz and includes peripherals like ADC, PWM, and communication modules (UART, SPI, I2C). The SSOP-28 package (5.3mm × 10.2mm) suits space-constrained designs. Its extended temperature range (-40°C to +125°C) and robust ESD protection make it suitable for industrial and automotive environments. The Enhanced Mid-Range Core (EMC) improves performance over baseline PIC architectures.

Structure and Working Principle

The microcontroller integrates a Harvard architecture CPU with 49 instructions and 8 stack levels. It uses a 14-bit wide instruction set for efficient code execution. Clock sources include internal oscillators (up to 32 MHz) and external crystals, with a fail-safe clock monitor for reliability. Peripherals are mapped via data memory and controlled through Special Function Registers (SFRs). Analog modules include a 10-bit ADC with 12 channels and two comparators. Digital features encompass 25 I/O pins with interrupt-on-change capability and enhanced PWM modules for motor control.

Key Features

Low-power modes (Sleep, Idle) reduce consumption to under 1 µA, critical for battery-operated devices. The nanoWatt XLP technology extends battery life further. Integrated CRC/SCAN functions enhance data integrity checks. The Configurable Logic Cell (CLC) allows hardware-based custom logic without CPU intervention, offloading real-time tasks. Peripheral Pin Select (PPS) enables flexible pin mapping, simplifying PCB layout. On-chip debug support speeds up development cycles.

Application Areas

Industrial: Sensor interfaces, PLCs, and HMI controllers leverage the ADC and communication peripherals. Automotive: Body control modules (BCM) use its robustness for lighting and actuator management. Consumer: Appliances and IoT edge devices benefit from low power and compact size. Medical: Portable diagnostic equipment employs its analog capabilities for signal conditioning. The MCU also suits LED lighting control and power management systems.

Maintenance and Precautions

Ensure power supply decoupling with 0.1 µF capacitors near VDD pins to minimize noise. Avoid exceeding absolute maximum ratings (e.g., 5.5V input) to prevent latch-up. Use ESD straps during handling. Firmware should include watchdog timer (WDT) routines to recover from crashes. For EMI-sensitive designs, enable clock switching and filter options. Regularly update development tools to access latest libraries and bug fixes.

B2B Procurement Guide

Order from authorized distributors like Digi-Key or Mouser to guarantee authenticity. Lead times vary; bulk orders (1,000+ units) may qualify for discounts. Verify packaging (tray, tube, or tape-and-reel) aligns with assembly workflows. Evaluate alternative part numbers (e.g., PIC16F1517 for more memory) if requirements change. Request samples for prototyping. Check for end-of-life (EOL) notices; Microchip typically offers migration paths to newer MCUs.
