MIPS-core, PIC32MX 32-bit MCU range gains larger-memory options

August 21, 2015 // By Graham Prophet
With up to 256 kB flash and performance up to 83 DMIPS, Microchip has added ‘cost-optimised’ variants to its PIC32MX1/2 32-bit microcontroller (MCU) family. Larger memory and smart peripheral mix lowers development costs: low-cost touch sensing and embedded control enables consumer, industrial and medical designs

Microchip’s latest parts have 256 kB Flash configuration and 16 kB of RAM in small-footprint packages, for low-cost applications that need complex algorithms and application code: they can be used with with Microchip’s software and tools for designs in graphics, touch sensing and general-purpose embedded control.

The PIC32MX1/2 MCU – based, as with others in the family, on the MIPS M4K core ( Imagination Technologies IP) – series features include an enhanced 8-bit Parallel Master Port (PMP) for graphics or external memory; a 10-bit, 1 Msample/sec, 13-channel Analogue-to-Digital Converter (ADC), support for SPI and I ²S serial communications interfaces and USB device/host/On-the-Go (OTG) functionality.

Microchip’s MPLAB Harmony software development framework integrates the licence, resale and support of Microchip and third-party middleware, drivers, libraries and Real-Time Operating Systems (RTOS). 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.

This PIC32MX1/2 series is supported by Microchip’s free MPLAB X Integrated Development Environment (IDE) and MPLAB XC32 Compiler for PIC32. The MPLAB ICD 3 In-Circuit Debugger (DV164035) priced at $199.95; and MPLAB REAL ICE In-Circuit Emulation System (DV244005) priced at $499.98, are also available. In addition, the following development board plug-in module supports this series: PIC32MX270F256D Plug-in-Module for Explorer 16 Development Board (MA320014), which is priced at $35.

These latest PIC32MX1/2 MCUs are available now in 28-pin QFN, SPDIP and SSOP packages and

44-pin QFN, TQFP and VTLA packages.
