lenovo 410m quanta le4 schematic 1
Technical Specifications
Technical Summary
The Quanta LE4 project is a notebook motherboard platform designed around the Intel Yonah/Merom CPU in a 478 Micro-FCPGA socket, paired with the Calistoga northbridge and ICH7-M southbridge. Graphics are handled by an integrated VGA function with options for 945PM, 945GM, or 940GML chipsets, alongside a discrete NVIDIA G72M GPU. System memory consists of two DDRII SODIMM slots supporting DDRII 266 and 333 MHz modules. Power management is handled by a MAX8771 CPU core controller, MAX8734 and MAX1993 system power regulators, and a MAX8632 for 1.8VSUS and 0.9V SMDDR_VREF. The embedded controller is a PC87551, and the audio subsystem uses a Conexant CX20549-12 codec with a MAX9755 amplifier. Networking is provided by either a BCM4401 10/100M or BCM5788 1G LAN controller. The charging IC is a MAX8724, and the card reader is controlled by a TI 8412.
