Microchip PIC32MX564F128H-I/MR: A Comprehensive Technical Overview

The Microchip PIC32MX564F128H-I/MR represents a powerful and versatile member of the PIC32MX family of 32-bit microcontrollers. Built around the high-performance MIPS32® M4K® core, this MCU operates at up to 80 MHz, delivering a robust 1.56 DMIPS/MHz, making it suitable for a wide range of demanding embedded applications, from industrial control and automation to advanced consumer devices.

A key feature of this microcontroller is its 128 KB of integrated Flash memory and 32 KB of SRAM. This substantial memory allocation provides ample space for complex application code and data handling, supporting sophisticated algorithms and communication protocols. The core is further enhanced with a 5-stage pipeline, allowing for efficient execution of instructions and maximizing processing throughput.

The peripheral set of the PIC32MX564F128H is exceptionally rich, designed to minimize external component count and simplify system design. It features a 10-bit Analog-to-Digital Converter (ADC) capable of 1 Msps conversion rates with up to 16 input channels, enabling precise acquisition of analog sensor data. For connectivity, it includes multiple serial communication modules, such as UART, SPI, and I2C™ ports, alongside two I2S modules for digital audio applications. A dedicated CAN 2.0b module is also integrated, which is critical for automotive and industrial networking.

Furthermore, this MCU includes a Parallel Master Port (PMP) for easy interfacing with parallel LCDs and other external memory-mapped devices, and a hardware crypto engine for accelerated AES, DES, and 3DES encryption, adding a critical layer of security for connected applications. Its operational flexibility is extended with support for 2.3V to 3.6V operation, making it compatible with a broad spectrum of power supplies.

Housed in a compact 64-QFN (7x7mm) package with the ‘-I’ suffix denoting an industrial temperature range (-40°C to +85°C), the PIC32MX564F128H-I/MR is engineered for reliability in harsh environments. Its combination of processing power, extensive peripherals, and robust packaging makes it a compelling choice for developers.
