Microchip Technology Inc. rolled out a series within its PIC32MX1/2 32bit microcontroller (MCU) line-up that flaunts a 256KB Flash configuration and 16KB of RAM in small-footprint packages. According to the company, the latest devices offer 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 PIC32MX1/2 MCU series boasts up to 50MHz/83DMIPS performance for executing advanced control applications and mTouch capacitive touch sensing. Additional features include an enhanced 8bit Parallel Master Port (PMP) for graphics or external memory, a 10bit, 1Msps, 13-channel ADC, support for SPI and I2S serial communications interfaces and USB device/host/On-the-Go (OTG) functionality.


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), the company added. 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 geared for medical and industrial applications, which also include displays with touch-sensing capabilities, along with general-purpose embedded control and connectivity capabilities.


This latest PIC32MX1/MX2 series is supported by Microchip's free MPLAB X IDE and MPLAB XC32 compiler for PIC32. The MPLAB ICD 3 In-Circuit Debugger (part DV164035, $199.95) and MPLAB REAL ICE In-Circuit Emulation System (part DV244005, $499.98) are also available. Additionally, the following development board plug-in module supports this series: PIC32MX270F256D Plug-in-Module for Explorer 16 Development Board (part MA320014, $35).

These latest PIC32MX1/2 MCUs are available in 28-pin QFN, SPDIP and SSOP packages and 44-pin QFN, TQFP and VTLA packages. Pricing starts at $1.91 each, in 10,000-unit quantities.
