XHSC HC32F4A2SITB-LQFP176

The HC32F4A2 series is a 32-bit microcontroller based on the ARM Cortex-M4 core, integrating a floating-point unit (FPU) with a maximum operating frequency of 240MHz, delivering up to 300 DMIPS of computational performance. The series features up to 2MB of dual-bank flash memory and 516KB of SRAM, including 128KB of single-cycle access high-speed RAM. The supply voltage range is 1.8V to 3.6V, with support for multiple reset sources including power-on reset and low-voltage detection reset. The device offers low-power characteristics with sleep, stop, and power-down modes, and supports independent power supply via the VBAT pin for RTC, backup registers, and backup SRAM to enable ultra-low-power operation. A rich set of peripherals significantly reduces CPU load, including a 16-channel DMAC, dedicated DMA for USB and Ethernet MAC, 8 data computing units (DCU), a math acceleration unit (MAU), a filter math accelerator (FMAC) supporting 16th-order FIR filtering, and an automatic output system (AOS) enabling mutual triggering between peripherals. Analog features include 3 independent 12-bit 2.5MSPS ADCs, 4 independent 12-bit 15MSPS DACs, 4 PGAs, 4 independent voltage comparators (CMP), and 1 on-chip temperature sensor. Timer resources include 8 multi-function 32/16-bit advanced control timers, 16 50ps high-resolution PWM (HRPWM) units, 3 16-bit motor control timers, 12 16-bit general-purpose timers (TimerA), 4 16-bit general-purpose timers (Timer2), 2 16-bit basic timers (Timer0), 1 RTC, and 2 watchdog timers (WDT). The MCU provides up to 142 GPIO pins, of which 134 are 5V-tolerant. Communication interfaces include 10 USARTs, 6 SPIs, 6 I2Cs, 4 I2Ss, 2 SDIO controllers, 1 QSPI, 2 CAN modules supporting CAN FD, 2 USB 2.0 interfaces supporting high-speed and full-speed respectively (with built-in full-speed PHY), and 1 10/100M Ethernet MAC. Additional features include an EXMC, data encryption (AES, SHA256/HMAC, TRNG), and a CRC calculation unit.
