Microchip’s new low-cost 32-bit MCUs feature large, scalable memory config

Microchip Technology Inc. has added a new series to its low-cost, high pin count 32-bit PIC32 microcontrollers (MCUs). By blending the key features of Microchip’s existing PIC32MX1/2 and PIC32MX5 MCU families, the new PIC32MX1/2/5 MCU series delivers designers the benefits of a rich peripheral set for a wide range of cost-sensitive applications that require complex code and higher feature integration at a lower cost.

With up to 83 DMIPS performance and large, scalable memory options from 64/8 KB to 512/64 KB Flash/RAM, the new MCUs are designed for executing the Bluetooth audio software required for low-cost Bluetooth audio applications, such as speakers, consumer music-player docks, noise-cancelling headsets and clock radios. Flexible, easy-to-use CAN2.0B controllers are also integrated into these MCUs, with DeviceNet addressing support and programmable bit rates up to 1 Mbps, along with system RAM for storing up to 1024 messages in 32 buffers. This feature allows designers to easily employ CAN communication schemes for industrial and automotive applications.

The new series boasts four SPI/I2S interfaces for audio processing and playback, a Parallel Master Port (PMP) and capacitive touch sensing hardware for graphics and touch-sensing interfaces; a 10-bit, 1 Msps, 48-channel Analog-to-Digital Converter (ADC); as well as a full-speed USB 2.0 Device/Host/OTG peripheral. To maximize data throughput, each MCU includes four general-purpose direct memory access controllers (DMAs) and two dedicated DMAs on each CAN and USB module.

The PIC32MX1/2/5 series is also supported by Microchip’s free MPLAB X integrated development environment (IDE), the MPLAB XC32 compiler for PIC32, the MPLAB ICD3 in-circuit debugger and the MPLAB REAL ICE in-circuit emulation system. New development tools that were created to support this PIC32MX1/2/5 series include the PIC32MX1/2/5 Starter Kit (part # DM320100, $69.99), PIC32MX570F512L Plug-in-Module for Explorer 16 Development Board (part # MA320015, $25) and PIC32MX270F512L Plug-in-Module for Bluetooth Audio Development Kit (part # MA320017, $25).

The new PIC32MX1/2/5 MCUs with the 40 MHz/66 DMIPS speed option are available now, in 64-pin TQFP and QFN packages and 100-pin TQFP packages. The 50 MHz/83 DMIPS speed option for this PIC32MX1/2/5 series is expected to be available starting in late January 2015. Pricing starts at $2.75 each, in 10,000-unit quantities.
