EPM570GF100C5N

EPM570GF100C5N is a CPLD (complex programmable logic device) from Altera, part of the MAX 7000S family.
- Key idea: A mid‑range programmable logic device used for glue logic, simple state machines, and small interface/controllers.
- Capacity: Roughly 570 logic elements (macrocells) with programmable I/O and small built-in memory options.
- Reprogrammable: Configured and reconfigured in-system (usually via JTAG) or from an external PROM/flash.
- Packaging/Voltage: Typically offered in a multi‑pin ceramic/plastic package suitable for 5V logic environments (exact packaging is denoted by the suffix in the model).
- Tooling: Supported by legacy Altera tools (MAX+Plus II) and older Quartus II flows for design, synthesis, and programming.
Use cases: glue logic, simple peripheral interfaces, state machines, and other small digital logic tasks where a full microcontroller or FPGA would be overkill. Note: as a legacy part, newer families (e.g., Intel/Altera MAX series successors) may offer better performance and support.

Here are the typical features of Altera EPM570GF100C5N (MAX II CPLD):
- 570 logic elements (LEs) for glue logic and small-state machines
- 100-pin FineLine BGA package (GF, RoHS-compliant)
