Description

EPM7256AETC100-10 is an Altera (now Intel) CPLD from the MAX 7000A family. It’s a 5V, non-volatile programmable logic device designed for glue logic, simple state machines, and control logic.
Key points:
- Density/capacity: 256 macrocells (macrocell-based logic blocks).
- Package: 100-pin TQFP (ETC indicates the package type).
- Speed grade: -10 ns.
- I/O: Comes with on-chip I/O pins suitable for a 5V system.
- Configuration: Configured at power-up from an external PROM/EEPROM or via in-system programming with appropriate tools.
- Use cases: Implementing combinational/sequential logic, decoders, counters, simple controllers.
Note: This is a legacy CPLD; verify current availability and tool support with Intel/ suppliers if you’re starting a new design.

Features

Key features of EPM7256AETC100-10 (MAX II CPLD):
- 256 macrocells in a 100-pin TQFP package
- MAX II CPLD architecture with fast carry and distributed RAM
- On-chip clock management with PLLs and global clock routing
- Flexible I/O banks with multiple voltage I/O options (3.3V I/O with 2.5V-tolerant options; some banks 1.8V-tolerant)
- Programmable I/O standards (LVTTL/LVCMOS, etc.)
- In-system reprogrammable via JTAG (external config memory options supported)
- Low-power operation with efficient standby modes
- Speed grade: -10 (typical timing specification for this device)
Notes: Always verify exact I/O counts and bank tolerances in the specific datasheet revision for your package and speed grade.

Pinout

- Pin count: 100 pins (100-pin package)
- Function: Altera EPM7256A CPLD (256-macrocell EPLD) used for programmable logic, glue logic, state machines, and I/O interfacing.

Manufacturer

Manufacturer: Altera Corporation (now part of Intel).
What kind of company: A semiconductor company that designs and sells programmable logic devices (PLDs), including CPLDs and FPGAs (e.g., the MAX 7000A series).

Application
