Microchip PIC32MX350F128L-I/PT: A Comprehensive Technical Overview

The Microchip PIC32MX350F128L-I/PT stands as a prominent member of the widely adopted PIC32MX family of 32-bit microcontrollers. This device is engineered to deliver a robust combination of processing performance, peripheral integration, and power efficiency, making it a versatile solution for a broad spectrum of embedded applications, from industrial control and automotive systems to consumer and Internet of Things (IoT) devices.

At the core of this microcontroller lies the high-performance MIPS32® M4K® processor core, capable of operating at up to 80 MHz. This provides a significant computational boost over traditional 8-bit and 16-bit architectures, enabling the handling of complex algorithms and real-time processing tasks with ease. The core is supported by a 128 KB of high-speed Flash program memory and 32 KB of RAM, offering ample space for sophisticated application code and data manipulation.

A key strength of the PIC32MX350F128L-I/PT is its rich set of integrated peripherals, designed to minimize external component count and simplify system design. It features a powerful 10-bit Analog-to-Digital Converter (ADC) with a throughput of up to 1 Msps, capable of simultaneously sampling multiple channels. For communication, it is exceptionally well-equipped, including:

Dual UART modules for serial communication.

Dual I²C™ modules for interfacing with sensors and other ICs.

Dual SPI modules for high-speed synchronous communication.

A CAN 2.0b module, which is critical for robust automotive and industrial network applications.

Furthermore, it incorporates a 16-bit Parallel Master Port (PMP) for easy interfacing with parallel LCDs, external memory, and other devices. The controller also includes five 16-bit timers/counters and a real-time clock and calendar (RTCC), providing essential timing and control functions.

The "PT" suffix in its part number denotes a 44-pin TQFP (Thin Quad Flat Pack) package. This surface-mount package offers a compact footprint while providing a sufficient number of I/O pins for connecting to various external components. The device is characterized for an industrial temperature range of -40°C to +85°C, ensuring reliable operation in harsh environments.

In terms of development support, designers benefit from Microchip's comprehensive ecosystem, including the free MPLAB® X Integrated Development Environment (IDE) and the powerful MPLAB Harmony v3 software framework. These tools drastically accelerate development time by providing libraries, drivers, and code examples for the microcontroller's extensive peripheral set.

ICGOODFIND: The PIC32MX350F128L-I/PT is a highly capable 32-bit microcontroller that strikes an excellent balance between processing power, a rich array of integrated peripherals (including CAN and a high-speed ADC), and power efficiency. Its strong support within a mature development ecosystem makes it a compelling and reliable choice for developers tackling complex embedded design challenges across multiple industries.
