Product Description

            The HC32F460 series is a high-performance MCU based on the ARM®Cortex®-M4 32-bit RISC CPU with a maximum operating frequency of 200MHz. The Cortex-M4 core integrates a floating-point unit (FPU) and a DSP, enabling single-precision floating-point arithmetic operations. It supports all ARM single-precision data processing instructions and data types, as well as a complete DSP instruction set. The kernel integrates an MPU unit and superimposes a dedicated MPU unit for DMAC to ensure the security of system operation.

             The HC32F460 series integrates high-speed on-chip memory, including MAX512KB Flash and MAX192KB SRAM. It integrates a Flash access acceleration unit to enable single-cycle program execution of the CPU on Flash. The polling bus matrix supports multiple bus hosts to access memory and peripherals simultaneously, improving operational performance. The bus host includes CPU, DMA, USB-specific DMA, etc. In addition to the bus matrix, it supports data transfer between peripheral devices, basic arithmetic operations and mutual triggering of events, which can significantly reduce the transaction processing load of the CPU.

             The HC32F460 series integrates a wealth of peripheral functions. It includes 2 independent 12-bit 2.5MSPS ADCs, 1 gain-adjustable PGA, 3 voltage comparators (CMP), and 3 multi-functional 16-bit PWM timers (Timer 6) supporting 6 complementary PWM outputs. The 3 motor PWM timers (Timer 4) support 18 complementary PWM outputs, and the 6 16-bit universal timers (Timer A) support 3 three-phase orthogonal encoding inputs and 48 independent Duty configurable PWM outputs. 11 serial communication interfaces (I2C/UART/SPI),1 QSPI interface,1 CAN,4 I2S supporting audio PLL,2 SDIO,1 USB FS Controller with on-chip FS PHY supporting Device/Host.

              The HC32F460 series supports a wide voltage range (1.8-3.6V), a wide temperature range (-40-105°C), and various low-power modes. In Run mode and Sleep mode, you can switch between ultra-high-speed mode (≤200MHz), high-speed mode (≤168MHz), and ultra-low-speed mode (≤8MHz). Supports fast wake-up in low-power mode, with the fastest wake-up in STOP mode reaching 2μs and in Power Down mode reaching 20μs.

Product application
