lenovo n200 n440 a-note-fingerprint schematic 1
Technical Specifications
Technical Summary
This Wistron Corporation Finger Print board, revision A3, dated September 22, 2006, is a dedicated sub-board designed for fingerprint authentication. The board is controlled by an AES1610-CDFTR-GP microcontroller in a 71.A1610.B0U package. It utilizes a 4Mbit S25FL004A0LNFI-GP SPI flash memory for firmware storage. Power management is handled by an AAT3221IGV-3D3-1GP charging IC and an AAT4610AIGV-GP power switch. The design incorporates a 12MHz crystal oscillator and an SR05-1-GP USB hub IC for interface connectivity. The board features a USB header connector and includes critical layout nodes such as DRIVE_RING#, FDRV, CL33, and VDD_3.3.
