EPM9320ALI84-10

EPM9320ALI84-10 is an Altera CPLD (EPM9320AL family) in an 84-pin package with speed grade -10. It provides a fixed array of programmable macrocells and interconnects to implement glue logic, finite-state machines, decoders, and simple interfaces. It is a non-volatile logic device (configuration memory retained after power-down) and does not include embedded RAM. Features typically include multiple I/O pins with programmable drive and I/O standards (varies by variant), and a straightforward clocking/topology suitable for timing-critical logic. Programming is done with Altera/Intel tools (Quartus II or older MAX+PLUS II) using Verilog/VHDL or schematic entry; configuration via standard programmers or JTAG. Common application areas are interface bridging, control logic, and other small, deterministic digital circuits. For exact electrical specs, I/O standards, power, and timing, consult the official EPM9320AL datasheet and package documentation.
