PMOD I3C Driver

Copyright (c) 2024 Antmicro

Overview

This project contains open hardware design files for a simple expansion PCB with two push-pull digital output drivers composed of discrete MOSFETs. This allows to use the board with FPGA-driven systems to implement I3C output stage driver which can act as open drain or push-pull. The driver topology is switchable via digital control signals from FPGA-side. A separate set of control signals allows to activate pull-up or pull-down resistors connected to the output signals. The design files were prepared in KiCad 9.x.

Key features

• Two independent digital output stages configurable as push-pull or open drain
• Switchable pull-up and pull-down resistors
• The board is compatible with PMOD (3.3V logic) expansion connector
• The board is compatible with a 24-pin proto header (J3) available on AMD (Xilinx) ZCU106 Evaluation Kit
