MICROCHIP PIC32CX1025SG41128-E/Z2X

This microcontroller integrates 1 MB Flash and 256 KB SRAM, with an optional Hardware Security Module supporting cryptographic functions, and features a 1 MSPS 12-bit ADC, QSPI, USB, Ethernet, and PTC. Operating conditions span 1.71V to 3.63V, with a maximum operating frequency of 120 MHz over the -40°C to +85°C temperature range and 100 MHz over the -40°C to +125°C range. The core features an Arm Cortex-M4F CPU running at up to 120 MHz, with 4 KB instruction and data caches, an 8-region MPU, FPU, and ETM. The memory system supports self-programmable Flash with ECC and dual-bank read-while-write, SRAM with ECC option, tightly coupled memory, and additional SRAM retainable in backup mode. Multiple low-power modes, sleep-wakeup peripherals, and an embedded buck/LDO regulator are provided. Up to 99 programmable I/O pins are available. Security features include a 256-bit AES engine supporting multiple modes, TRNG, Public Key Cryptography Controller, SHA-based Integrity Check Module, and an optional Hardware Security Module supporting secure boot, secure update, X.509 certificate handling, and various cryptographic algorithms such as ECDSA and RSA. The peripheral set is rich, including an event system, eight serial communication interfaces configurable as USART/I2C/SPI and more, multiple timer/counters, RTC, watchdog, CRC, I2S, position decoder, frequency meter, configurable custom logic, dual-channel 12-bit 1 Msps ADC and DAC, analog comparators, Parallel Capture Controller, and PTC supporting both self-capacitance and mutual-capacitance touch sensing. High-performance peripherals include a 32-channel DMA controller, two SD/MMC host controllers, one QSPI with XIP support, one Ethernet MAC with dedicated DMA and IEEE 1588 support, and two CAN controllers supporting CAN-FD.
