NHS3152数据手册恩XP中文资料规格书

描述 Description

The NXP NHS3152 is an IC optimized for logging and sensing. With its embedded NFC interface, internal temperature sensor, ADC, DAC, current sensor and direct battery connection, it supports an effective system solution with a minimal number of external components.
The embedded Arm® Cortex®-M0+ offers flexibility to the users of this IC to implement their own dedicated solution. The NHS3152 contains multiple features, including multiple Power-down modes and a selectable CPU frequency of up to 8 MHz, for ultra low power consumption.
Users can program this NHS3152 with the industry-wide standard solutions for Arm® Cortex®-M0+ processors.
