Features

The EPM7256AETI144-7N is a MAX 7000AE series CPLD from Intel (formerly Altera). Key features:
- 256 macrocells, 5,000 usable gates
- 7.5 ns pin-to-pin logic delay (speed grade -7N)
- 144-pin TQFP package
- 3.3V operation with 5V-tolerant I/O
- In-system programmable (ISP) via JTAG
- High-density PLD with EEPROM-based configuration
- Advanced architecture: MultiArray Matrix (MAX) with fast parallel expanders
- Low power: 0.5–1.5 mA standby current
- Security bit for design protection
Ideal for high-speed logic integration, glue logic, and control applications.

Pinout

The EPM7256AETI144-7N is an Altera MAX 7000AE series CPLD with:
- Pin Count: 144 (TQFP package)
- Functions:
- Logic Elements: 256
- Macrocells: 256
- I/O Pins: 100 (bidirectional, 5V tolerant)
- Speed Grade: -7N (7ns pin-to-pin delay)
- Features: In-system programmability (ISP), JTAG support, and non-volatile EEPROM storage.
It is used for glue logic, interface bridging, and control applications.

Application

The EPM7256AETI144-7N, a CPLD from Altera (now Intel), is used in:
- Digital Logic Design – Glue logic, bus interfacing.
- Embedded Systems – Control logic, state machines.
- Communications – Protocol bridging, signal conditioning.
- Industrial Automation – Motor control, I/O expansion.
- Consumer Electronics – Interface management, timing control.
Its 144-pin TQFP package and 5V tolerance make it suitable for legacy systems requiring moderate logic density and fast response times.

Package

The EPM7256AETI144-7N is a CPLD (Complex Programmable Logic Device) from Altera's MAX 7000S series. It comes in a 144-pin TQFP (Thin Quad Flat Package). The package type is TQFP144, which is a surface-mount design with a 20mm x 20mm body and 0.5mm pin pitch. The "-7N" suffix indicates a 7ns speed grade.
