 32-bit PIC32 MCU families with 128 KB RAM and connectivity options

Microchip has introduced the PIC32MX5/6/7, a new families with 80 MHz 32-bit PIC32 microcontroller (MCU) portfolio that provide up to 128 Kbytes of RAM and connectivity options, including 10/100 Mbps Ethernet, two CAN2.0b controllers, USB Host, Device and OTG, and 6 UART, 5 I2C and 4 SPI ports. These PIC32MX5/6/7 families are suitable for data-intensive applications.

Microchip's free software stacks, available in source-code form, complement these new MCU families making it easy for embedded designers to add connectivity to their applications.

"The level of integration on Microchip's new PIC32 32-bit MCU families will greatly reduce system costs for many embedded designs," said Tony Massimini, chief of technology at Semico Research Corporation. "Microchip has done a great job of integrating important connectivity peripherals with a large amount of system RAM, making them a serious contender for multi-protocol embedded networking applications."

Designers have full access to up to 128 KB of RAM for simultaneous use with the Ethernet, USB and CAN buffers. The integrated Ethernet, CAN and USB modules have a built-in DMA interface to maximize data throughput.

"These families couple the PIC32's leading performance with new connectivity features and all the integrated RAM needed for running multiple software stacks with ease," said Sumit Mitra vice president of Microchip's High Performance Microcontroller Division, "This enables innovative connectivity and human-interface applications at lower price points and with greater design simplicity. Benchmarks continue to show the best-in-class performance of the PIC32, as published in recent EEMBC CoreMark scores and established Dhrystone scores."

Each MCU has a unique, factory-preprogrammed Ethernet MAC address, which simplifies the manufacturing process.

CAN2.0b controllers have been added to the PIC32, which use system RAM for storing up to 1024 messages in 32 buffers. Advanced filtering capabilities include user selectable filter-to-buffer mapping with 32 filters and 4 filter masks. All of these functions adapt CAN communication schemes to their applications.

Microchip offers free TCP/IP and USB software stacks, including full source code, to further enable easy software development. Available software includes two TCP/IP software stacks, along with libraries for USB Host and Device, Advanced Encryption Standard (AES), multiple file systems, advanced graphics, audio, and many other software products.

Migrating software across Microchip's 600-plus 8-, 16- and 32-bit PIC microcontroller portfolio is easy, as its development tools, USB stacks and TCP/IP stacks span the entire range of PIC MCUs. Additionally, the new PIC32MX5/6/7 families are pin compatible with the existing PIC32 and 16-bit PIC24F USB MCU families.

The suggested applications for the new PIC32MX5/6/7 families include Communications (point-of-sale terminals, Web servers, CAN-to-Ethernet-to-USB bridges), Industrial/Medical (automation, controllers, medical devices, security monitoring), Consumer/Appliance (audio, MP3 decoders, displays, small appliances, fitness equipment) and automotive (aftermarket, car alarms, GPS).
