Technical Specifications
Technical Summary
The Wistron JEDI 13" (Project Code HELLCAT 13", Board Number 19721, Revision DVT1) is a Comet Lake-U based platform documented under schematic number A31106. The system uses UMA-only graphics with LPDDR3 memory configured as 2Rx16 memory down across two channels. The EC/KBC is a Microchip MEC1515, and the BIOS is stored on a 16MB+8MB Quad Read Flash ROM. Audio is handled by a Realtek ALC3254 codec. The charging solution uses a Cypress CCG5 C controller. Thermal monitoring is provided by a Nuvoton NCT7718W sensor. The card reader is a Realtak RTS5144, and the HDMI interface uses a Parade PS186 level shifter. The system also integrates a Parade PS8762D USB hub and a TPM solution combining Nuvoton NPCT750 and ST ST33HT.
