Dell 3420 11282-1 Schematic
Technical Specifications
Technical Summary
This Wistron-manufactured motherboard, designated Enrico Caruso 14 MLK DIS with document number A31104 revision X02, supports Intel Ivy Bridge and Sandy Bridge CPU platforms paired with an Intel HM75 Panther Point PCH in a BGA989 package. The graphics architecture supports multiple configurations including Muxless, UMA ONLY, and Optimus solution with discrete gDDR3 900MHz VRAM. The system is managed by a Nuvoton NPCE885P EC/KBC and utilizes an 8MB Flash ROM for BIOS storage. Audio is handled by a Cirrus CS4213 codec. Power management includes a BQ24707 TI charger and multiple DC/DC converters from ADP3211, TPS51216, TPS51125, TPS51219, RT8068, APL5916, and VT1318+1323. Memory configuration supports DDRIII 1333/1600 across two slots on Channel A and a Channel B. Networking is provided by Realtek RTL8111F Gigabit LAN and Realtek RTL8105E-VD Fast Ethernet, with 802.11a/b/g Mini-Card WLAN+BT wireless connectivity. Thermal monitoring is handled by an NCT7718W sensor, and a Realtek RTS5138 card reader is integrated.
