lenovo g430 le6 mb d3b 0423 rev 1a schematic 1
Technical Specifications
Technical Summary
The Quanta LE6 project is a laptop motherboard designed around the Intel Penryn 478P (uPGA)/35W CPU platform, paired with the Cantiga northbridge and ICH-9M southbridge. Graphics are handled by a GM T G9931 P1UX3J Micro 385X1 GPU. The system memory architecture consists of two DDRII-SODIMM slots supporting DDRII 667/800 MHz modules. Networking is provided by a Broadcom BCM 5906M 10/100 LAN controller. Audio processing is managed by a CX20561-12Z audio codec with a TPA6017A2 audio amplifier. The charging subsystem uses an ISL6251AHAZ-T charger IC, while system power regulation is handled by an ISL6237IRZ-T IC and CPU core power by an ISL6266A IC. The system discharge controller is an ITE8502E-L. A card reader is implemented using an ALPS RS355B MLF64PIN controller. The motherboard utilizes a 6-layer PCB stack-up.
