Summary
The PIC32MX3/MX4 microcontrollers oer the perfect combination of 32-bit per-
formance, memory and integrated peripherals at a low cost. These devices run up
to 120 MHz/150 DMIPS and provide 64/16K, 128/32K, 256/64K, and 512/128K
Flash/RAM options. The PIC32MX3/MX4 family boasts a rich set of integrated
peripherals including two SPI/I
2
S™ interfaces for audio codecs, capacitive touch-
sensing, an 8-bit Parallel Master Port (PMP) for graphics or external memory,
an on-board 28 channel, 1 Msps Analog-to-Digital Converter (ADC), as well as
full-speed USB 2.0 Device/Host/OTG. These devices are coupled with software
and tools support to launch products in connectivity, graphics, Bluetooth-enabled
digital audio and general purpose embedded control.
