Microchip Technology PIC32CM GC 32-Bit Arm® Cortex®-M23 MCUs

Microchip Technology PIC32CM GC 32-Bit Arm® Cortex®-M23 Microcontrollers (MCUs) are a family of low-power 32-bit Arm-based MCUs that offer safety, CAN-FD, SERCOMs (USART, SPI, I2C, LIN, etc.), full-speed USB, enhanced touch, and advanced analog features. The Arm Cortex-M23 CPU can run up to 72MHz and has a 2.64 CoreMark/MHz and 1.03 DMIPS/MHz rating. The Microchip Technology PIC32CM GC advanced analog features include a 12-bit Analog-to-Digital Converter (ADC) module with up to 4.5Msps, up to 12 single-ended channels, or three differential and six single-ended channels. The enhanced peripheral touch controller features up to 324 (18 x 18) mutual-capacitance channels and up to 36 self-capacitance channels, with Driven Shield+ technology. These devices are available in TQFP-48, VQFN-48, TQFP-64, VQFN-64, or TQFP-100 packages.
