Microchip Technology recently announced a new series of low pin count 32-bit PIC32 microcontrollers that provide 61 DMIPS of performance in packages as small as 5 mm x 5 mm for space- and cost- constrained designs. The PIC32 “MX1” and “MX2” MCUs are the smallest and lowest-cost PIC32 microcontrollers, and are the first PIC32s to feature dedicated audio and capacitive-sensing peripherals. These new MCUs are targeted for the automotive, consumer, industrial, and medical markets.
Rated for operation up to 105°C, the PIC32 MX1 and MX2 MCUs include up to 32 KB of Flash, and 8 KB of SRAM; two I2S interfaces for audio processing; Microchip’s Charge Time Measurement Unit (CTMU) peripheral for adding mTouch™ capacitive touch buttons or advanced sensors; and an 8-bit Parallel Master Port (PMP) interface for graphics or external memory. The new devices also feature an on-chip 10-bit, 1 Msps, 13-channel Analog-to-Digital Converter (ADC), as well as USB 2.0, and serial-communications peripherals.
Further easing the design effort is Microchip’s Peripheral Pin Select feature, which allows developers to “remap” most digital-function pins in the chip, making layout and design modifications significantly simpler. The PIC32 MX1 and MX2 devices are compatible with Microchip’s 16-bit PIC24F product line for easy migration, and are supported by the MPLAB® X IDE, the single development environment for all of Microchip’s 8-, 16- and 32-bit MCUs.
Microchip also unveiled the MPLAB Starter Kit for PIC32MX1XX/2XX MCUs (part # DM320013, $109.99), today. The USB-powered kit features a PIC32MX220F032 with 32 KB of Flash and 8 KB RAM, as well as a 2” color TFT display (220 x 176 pixel), capacitive-touch slider and buttons, SD-card storage, and 24-bit audio playback. Additionally, the new PIC32MX CTMU Evaluation Board (part # AC323027, $24.95) is available, as well as the new PIC32MX220F032D Plug-In Module (part # MA320011, $24.95) for the Explorer 16 Development Board.
Pricing and availability
The PIC32MX110F016B and PIC32MX220F032 MCUs are available in 28-pin SPDIP, SSOP, SOIC and QFN packages; and in 44-pin QFN, VTLA and TQFP packages. Pricing starts at $1.58 each, in 10,000-unit quantities. Samples can be ordered today, at http://www.microchip.com/get/EA7A. Volume-production quantities of the MCUs can be purchased today, at http://www.microchip.com/get/99H0.
A 36-pin VTLA package option with a .5 mm pin pitch is available for limited sampling, today. Industrial temperature range products with operation up to 85°C are available today, with 105°C options expected in late CQ4 2011. Pricing for all of these devices starts at $1.58 each, in 10,000-unit quantities, as well.
