Customer: A battery supplier to CRRC
Integrated Devices: 4 chips (32-bit MCU, DCDC chip, NorFlash memory chip, operational amplifier) + 38 passive components
① MCU: Replaced ST 32-bit MCU with Shenzhen Hangshun 103 series MCU
② DC/DC chip: Texas Instruments (TI)
③ NorFlash: GigaDevice
④ Operational amplifier: Beijing SG Micro
⑤ Passive components: Domestic passive components
Addressing Customer Pain Points:
① Reduce system size/volume (by more than 60%) – size constraints due to mounting on top of batteries
② Resolve ST MCU shortage and pricing issues – at least 15% lower than ST's normal price
③ Confidentiality and anti-copy protection, with ease of subsequent installation
Annual Shipment: 1.5kk pcs/year
