Microchip expands 32-bit PIC microcontroller portfolio with additional memory options for cost-effective ethernet, CAN and USB connectivity
New six-member PIC32 family also features lower power consumption and
Higherflash endurance
Bangalore, January 28, 2011: Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, has announced a new, six-member family of that provides the same integrated Ethernet, CAN, USB and serial connectivity peripherals with new, more cost-effective memory options. Additionally, design enhancements have been made that provide lower power consumption of 0.5 mA/MHz active current, higher Flash memory endurance of 20k read/write cycles and better EEPROM emulation capability. And, by maintaining common pin outs, the portfolio provides designers with a seamless migration path to achieve the correct balance of memory and cost for their high-performance applications.
Embedded designers are constantly looking for ways to lower their costs without sacrificing performance or functionality. Microchip's newest 80 MHz PIC32 microcontroller family meets these needs by maintaining best-in-class performance of 1.56 DMIPS/MHz, and integrating Ethernet, CAN, USB and multiple serial communication channels, while offering more cost-effective memory options. Specifically, the family offers 32 Kbytes of RAM and up to 140 Kbytes of Flash.
"We are committed to building upon the success of the PIC32 portfolio by offering six new microcontrollers, each available in five different pin-compatible packages," said Sumit Mitra, vice president of Microchip's High Performance Microcontroller Division. "These new high-performance, connectivity-rich MCUs give our customers lower-cost memory options that support scalability and seamless migration with the rest of our growing 3product line."
"Microchip has maximized the raw performance of the MIPS32 M4K core, while taking advantage of its high flexibility, to create a architecture that exceeds the requirements of demanding embedded designs," said Art Swift, vice president of marketing and business development, MIPS Technologies, Inc. "Microchip is offering great value to designers through the price to performance ratio of this new PIC32 family, combined with its extensive set of integrated peripherals."
Example applications for this new PIC32 family include: Communications (point-of-sale terminals, Web servers, multi-protocol bridges); Industrial/Medical (automation controllers, medical devices, security monitoring); Consumer/Appliance (audio, MP3 decoders, displays, small appliances, fitness equipment); Automotive (aftermarket, car alarms, GPS).

Adding memory to PIC microcontroller? Interface type?
I would like to add some EEPROM memory to my PIC16F84A microcontroller. I was wondering what the interface type is for this PIC (1-wire, 2-wire, 12C, etc...)?
What's the interface type for the PIC18F2585, and the PIC32MX340F512H-80I/MR? I know that I would NEVER need extra memory for the PIC32, but I would just like to know the interface type. Thanks!

I've perused the PIC16F84A datasheet. Usually any interface capability would be noted on the Features page or the Block Diagram or sometimes in the Pinout Description. But I saw no interfaces except ICSP (in-circuit serial programming) and GPIO (general purpose I/O). Its doubtful the ICSP could be a general serial port, at least without giving up the original function. I've seen people bit-bang a GPIO to make a serial interface, which you could use a last resort. External serial memory usually works with SPI or I2C ports. Check out this Digikey link for PIC interfaces:
