Microchip PIC32MX440F128HT-80I/MR 32-bit Microcontroller Product Overview and Technical Specifications
The Microchip PIC32MX440F128HT-80I/MR is a high-performance member of the PIC32MX family of 32-bit microcontrollers (MCUs), built around the industry-standard MIPS32® M4K® core. This MCU is engineered to deliver a powerful combination of processing performance, advanced peripherals, and connectivity options, making it an ideal solution for a wide range of demanding embedded applications, including industrial control, automotive, consumer, and general-purpose markets.
At the heart of this device is a 80 MHz CPU capable of delivering up to 1.56 DMIPS/MHz (Dhrystone 2.1), resulting in a total performance of 125 DMIPS. This computational power is supported by a large integrated memory configuration, featuring 128 KB of Flash memory and 32 KB of RAM, providing ample space for complex application code and data handling.
A key strength of the PIC32MX440F128HT lies in its rich set of integrated peripherals. It includes a powerful 10-bit Analog-to-Digital Converter (ADC) with a throughput of up to 1 Msps, multiple UART, SPI, and I2C™ serial communication modules for interfacing with a vast array of sensors and other components, and two CAN (Controller Area Network) 2.0B modules, which are critical for robust automotive and industrial network communications. Furthermore, it features 5x 16-bit timers/counters and 5x capture/compare/PWM (CCP) modules for precise timing and motor control applications.
The device is housed in a 64-pin QFN (MR) package, which offers a compact footprint suitable for space-constrained designs. The "HT" suffix in the part number denotes the extended temperature range of -40°C to +150°C, ensuring reliable operation in harsh environments. Its operating voltage ranges from 2.3V to 3.6V, contributing to lower power consumption.
