New PIC32MX1/2 32-bit Microcontrollers with 256KB Flash Memory


Large Memory and Smart Peripheral Mix Lowers Development Costs for Touch-Sensing and Embedded-Control Applications


Microchip have released a new series within its PIC32MX1/2 32-bit microcontroller (MCU) family that features a large 256 KB Flash configuration and 16 KB of RAM in small-footprint packages. These latest additions to this popular MCU family provide flexibility to low-cost applications that need complex algorithms and application code, and they are coupled with Microchip's comprehensive software and tools for designs in graphics, touch sensing and general-purpose embedded control.

The new PIC32MX1/2 MCU series boasts a wide variety of rich features, including up to 50 MHz/83 DMIPS performance for executing advanced control applications and mTouch® capacitive touch sensing. Additional features include an enhanced 8-bit Parallel Master Port (PMP) for graphics or external memory, a 10-bit, 1 Msps, 13-channel Analog-to-Digital Converter (ADC), support for SPI and I2S serial communications interfaces and USB device/host/On-the-Go (OTG) functionality.

“This new 32-bit MCU series is ideal for the designers of embedded-control and touch applications who are looking for low-cost and smaller package options,” said Rod Drake, vice president of Microchip's MCU32 Division. “With their cost-optimized Flash configuration, performance up to 83 DMIPS, package sizes down to 6x6 mm and 0.5mm pitch and feature-packed peripherals, these MCUs offer increased flexibility to a broad range of applications while keeping design size and cost low.”

Microchip’s MPLAB® Harmony software development framework further simplifies designs, by integrating the license, resale and support of Microchip and third-party middleware, drivers, libraries and Real-Time Operating Systems (RTOS). Specifically, Microchip's readily available software packages-including USB stacks and Graphics and Touch libraries-can greatly reduce the development time of applications such as consumer, industrial and general-purpose embedded control.

Designers seeking to launch consumer products with capacitive touch screens, touch buttons or sliders, as well as USB device/host/OTG connectivity, can benefit from the functionality of the PIC32MX1/2 series of MCUs. The feature-rich peripherals of these MCUs are also ideal for medical and industrial applications, which also include displays with touch-sensing capabilities, along with general-purpose embedded control and connectivity capabilities.
