Microchip Technology introduced the PIC32MX5, PIC32MX6, and PIC32MX7 32-bit PIC32 microcontroller (MCU) families. The PIC32MX5/6/7 MCUs are ideal for 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). The three new PIC32MX5/6/7 microcontroller families are available today for sampling and volume production. 10,000 unit pricing ranges from $4.73 each for the PIC32MX575F256H, up to $6.55 each for the PIC32MX795F512L. Packaging options include 100-pin TQFP and BGA packages, and 64-pin TQFP and QFN packages.
The new PIC32 32-bit microcontrollers feature up to 128 Kbytes of RAM, 10/100 Mbps Ethernet, two CAN2.0b controllers, USB Host, OTG, 6 UART, 5 I2C, and 4 SPI ports. The PIC32MX5/6/7 MCU families are complemented by Microchip’s free software stacks, available in source-code form, making it easier for embedded designers to add connectivity to their applications.
The new PIC32MX5/6/7 families are designed specifically for the data-intensive 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.
The integrated 100 Mbps Ethernet MAC uses an industry-standard RMII/MIII interface to low-cost, commodity Physical Interface chips (PHYs). Additionally, each MCU has a unique, factory-preprogrammed Ethernet MAC address, which simplifies the manufacturing process.
Flexible, easy-to-use 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 allow designers to easily 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, quicker time to market and lower overall costs. 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.
