This allows you to choose between two different generations of Altera/Intel CPLD chips in the TQFP-100 package: +2. **Multi-CPLD:** The board is designed for universal power supply and logic level tolerance. Two types of FPGA chips in TQFP-100 packages are supported: * **Altera MAX 7000S:** EPM7128STC100 / EPM7160STC100. *** ## CPLD Firmware Programming -Thanks to the universal power distribution layout, this project natively supports firmware code targeting different Altera/Intel CPLD generations. - This repository includes custom modifications and provides full, seamless integration with the **alternative firmware repository by [andykarpov/zx-eq-firmware](https://github.com/andykarpov/zx-eq-firmware)**. This third-party code branch vastly broadens the choice of compatible LED bar components and pin polarities. ### Available Firmware Binaries
