Wafer-Level Chip Scale Package （WLCSP） is one of the most cost-effective and space-efficient packaging options. The die size of Puya products has leading competitiveness, so Puya WLCSP is a true chip-scale package.  Puya provides WLCSP SPI NOR Flash, IIC EEPROM & VCM Driver products for mobile or portable form facotr applications, such as 3D-CCM, digital cameras , smart watches, GPS navigation devices, etc.

SPI NOR Flash

Base on the chip size, Puya develops a series of SPI NOR Flash WLCSP products. All of Puya's  WLCSP products are manufactured and tested in SMIC to ensure the quality and reliability.
