The Microchip PIC32MX440F512H-80I/PT represents a high-performance member of the widely adopted PIC32MX family of 32-bit microcontrollers. Engineered for applications demanding robust computational power, extensive memory, and a rich set of peripherals, this MCU is a cornerstone for complex embedded designs in industrial, medical, and consumer markets.
At the heart of this device lies the MIPS32® M4K® core, capable of operating at up to 80 MHz, delivering a performance of 1.56 DMIPS/MHz. This processing power is essential for handling real-time control algorithms, data processing, and multi-tasking operations efficiently. The core is supported by a sophisticated memory architecture, featuring 512 KB of Flash program memory and 128 KB of RAM. This substantial memory space is critical for storing large application code and managing complex data sets without external memory components.
A key strength of the PIC32MX440F512H is its extensive and diverse peripheral set, designed to interface with a vast array of sensors, actuators, and communication modules. It includes multiple serial communication channels such as UART, SPI, and I²C modules, facilitating easy connection to other ICs and systems. For analog needs, it incorporates a 10-bit Analog-to-Digital Converter (ADC) with up to 16 channels, enabling precise measurement of analog signals. Furthermore, it is equipped with 5x 16-bit timers/counters and 5x Capture/Compare/PWM (CCP) modules, providing flexible control for motor drives, power conversion, and waveform generation.
Connectivity is a standout feature. The microcontroller includes a USB 2.0 Full-Speed OTG (On-The-Go) module, allowing the device to act as either a host or a peripheral, which is invaluable for creating data loggers, human interface devices (HID), or communication gateways. It also features a 10/100 Ethernet MAC controller, enabling robust wired network connectivity for IoT and industrial networking applications.
The part number suffix 80I/PT provides vital package and temperature range information. The "80I" denotes an industrial temperature range (-40°C to +85°C), making it suitable for harsh environments. The "PT" specifies a 100-pin TQFP package, which offers a compact form factor while providing ample I/O pins for complex projects.
Development is supported by a mature ecosystem, including the MPLAB X IDE and the Harmony v3 framework, which provides integrated software libraries and drivers to accelerate development and ensure code reliability.
