Technical Specifications
Technical Summary
The Quanta CW4 project motherboard is built around an Intel Merom 478P (uPGA) CPU platform paired with a Crestline Northbridge and ICH-8M Southbridge. System management is handled by an ITE 8512 EC/KBC. The board features an NVIDIA NB8M GPU with Azalia graphics architecture, supporting dual DDRII SODIMM slots. Audio is provided by a Realtek ALC 268 codec, while networking is managed by a Broadcom BCM5787/5906 LAN IC. Storage connectivity includes a Ricoh 832 card reader. Power management is distributed across multiple ICs including the ISL6236 system power controller, MAX1993ETG VGA core regulator, MAX8770 CPU core regulator, MAX8724 system charger, MAX8632ETI+ DDR II SM DDR_VTERM regulator, and ISL6269A for +1.05V/+1.5V rails. Clock generation is handled by an ICS9LPRS365AGLF in a 64-pin TSSOP package.
