Maxim公司的MAX32625/MAX32626是基于ARM® Cortex®-M4F核的32位微控制器(MCU),具有超低功耗和高效率信号处理功能以及容易使用.内部96MHz的振荡器提供了高性能,而4MHz振荡器支持需要常开监视的最低功耗.器件集成了512KB闪存和160KB SRAM,1.2V核电压,1.8V - 3.3V I/O电压.主要用在健身监视器,手持医疗设备,传感器集线器,运动手表以及可穿戴医疗贴件.本文介绍了MAX32625/MAX32626主要特性,简化框图以及MAX32625评估板主要特性,框图,电路图,材料清单和PCB元件布局图.

The MAX32625/MAX32626 is an ARM® Cortex®-M4F 32-bit microcontroller with an unconnected point unit, ideal for the emerging category of wearable medical and fitness applications. The architecture combines ultra-low power, high-efficiency signal processing functionality and ease of use. An internal 96MHz oscillator provides high-performance capability, and the internal 4MHz oscillator supports minimal power consumption for applications requiring always-on monitoring. The device provides 512kB of flash and 160kB of SRAM.

The device features four powerful and flexible power modes. A peripheral management unit (PMU) enables intelligent peripheral control with up to six channels to significantly reduce power consumption. Built-in dynamic clock gating and firmware-controlled power gating allows the user to optimize power for the specific application.

Multiple SPI, UART, and I2C serial interfaces are provided, as well as a 1-Wire® master and USB, allowing for interconnection to a wide variety of external sensors. A four-input, 10-bit delta-sigma ADC monitors analog input from external sensors. The MAX32625L is a lower-cost version of the MAX32625, providing 256kB of flash and 128kB of SRAM.

The MAX32626 is a secure version of the MAX32625. It incorporates a trust protection unit (TPU) with encryption and advanced security features. These features include a modular arithmetic accelerator (MAA) for ECDSA, a hardware PRNG entropy generator, and a secure boot loader. Both the MAX32626 and the MAX32625 provide a hardware AES engine.
