Microchip PIC16F15355T-I/SO 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC16F15355T-I/SO is a versatile 8-bit microcontroller unit (MCU) from Microchip Technology’s enhanced mid-range PIC16F family. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this device is engineered for a broad spectrum of embedded control applications, offering a compelling blend of core independent peripherals (CIPs), analog integration, and low-power operation.

Built around an enhanced 8-bit RISC CPU core operating at up to 32 MHz, the PIC16F15355T-I/SO delivers a robust 16 MIPS performance. It features 14 KB of Flash program memory and 1024 bytes of RAM, providing ample space for complex firmware. A key strength of this MCU lies in its rich set of integrated peripherals designed to minimize CPU intervention and boost system efficiency. These include multiple communication interfaces such as EUSART, I2C, and SPI, alongside advanced PWM outputs and timers.

A standout feature is its suite of Core Independent Peripherals (CIPs). These include:

Configurable Logic Cells (CLC): Allow the creation of custom logic functions without code, enabling hardware-based decision-making.

Complementary Waveform Generator (CWG): Ideal for driving power conversion circuits like half-bridge and full-bridge drivers with dead-band control.

Windowed Watchdog Timer (WWDT) & Programmable Brown-Out Reset (BOR): Enhance system reliability and safety in noisy environments.

The analog capabilities are equally impressive. The MCU integrates a 10-bit ADC with up to 35 channels, a 5-bit Digital-to-Analog Converter (DAC), and two comparators. This high level of analog integration makes it perfectly suited for sensor interface, data acquisition, and real-time control systems.

Target applications for the PIC16F15355T-I/SO are diverse, spanning:

Automotive: Body electronics, lighting control, and sensors.

Industrial: Motor control systems, power supplies, and industrial automation.

Consumer Electronics: Appliances, power tools, and user interface control.

Internet of Things (IoT): Smart sensors and edge nodes, facilitated by its low-power modes.

ICGOODFIND: The PIC16F15355T-I/SO is a highly integrated and flexible 8-bit MCU. Its powerful combination of CIPs, extensive analog features, and robust communication options makes it an exceptional choice for designers seeking to create efficient, reliable, and cost-effective embedded systems for automotive, industrial, and consumer markets.
