Product Overview
Favorites
CSA37F71
Supports MEMS and bridge resistor sensor detection Built-in 60K Flash. All structural problems can be easily solved by algorithms Single-channel pressure detection: 20 uA@10Hz

CSA37F71 integrates a high-performance, low-power MCU and an analog front-end for pressure sensor signal detection. Based on changes in force, it can detect pressure or multi-level forces, and control the corresponding human-machine interaction interface. Utilizing CHIPSEA’s independently developed algorithm, the chip can achieve a high signal-to-noise ratio and accurately identify pressing or multi-level forces.
