Lenovo Thinkpad E14 Gen 4 AMD NM-E501 Schematic
Technical Specifications
Technical Summary
This LCFC NM-E501 Rev0.3 motherboard is designed for the Lenovo ThinkPad E14/E15 GEN4 N-1 platform, built around the AMD Barcelo FP6 processor with integrated Radeon graphics. The board features dual-channel DDR4 memory architecture combining onboard memory-down with one DDR4 SO-DIMM slot. System firmware is stored on a 256Mbit SPI flash IC. Embedded controller functions are handled by an ITE8227E. Audio processing is managed by a Realtek ALC3287 codec. The charging subsystem uses a TI SN1702001 AOU charger IC. USB-C connectivity and card reader functions are supported by a Realtek RTS5457 controller. The board includes an HDMI 1.4 connector, M.2 WLAN/BT slot, and multiple USB 2.0 and USB 3.0 Gen 1 ports. The design date is November 2, 2021, with revision 0.3.
