Technical Specifications
Technical Summary
This Compal Electronics LS-3548P1.0 Fingerprint Board, issued September 15, 2006, is a dedicated peripheral module designed for fingerprint sensor integration. The board utilizes an M95256-WMW6TG SO8 SPI flash for firmware storage and a TC7WH123FK SSOP8 logic IC for control functions. Power management is handled by an SI2301BDS-T1-E3 SOT23-3 MOSFET, while the fingerprint sensor interface is managed by a TCS4BA-6A-0 BGA27 charging/interface IC. The design incorporates a 12MHz DSX840GA crystal oscillator for timing, PRTR5V0U2X SOT143 ESD protection diodes on the USB data lines, and an MBK1608301YZF 0603 ferrite bead for power filtering. The board communicates via a standard USB interface with SPI bus lines (MCS#, MCLK, MOSI, MISO) for sensor data transfer, and includes gold finger edge connector pads for mechanical and electrical connection to the host system.
