Altera EPM7512AEBI256-10 Datasheet
The EPM7512AEBI256-10 (often referenced alongside the core MAX 7000B architecture series) is a high-density, 2.5V EEPROM-based Complex Programmable Logic Device (CPLD) engineered for high-performance, low-power industrial and communications infrastructure applications. Featuring 512 macrocells and 10,000 usable gates, this CPLD delivers predictable pin-to-pin logic delays (tPD = 5.5 ns) and internal counter frequencies reaching up to 163.9 MHz.
Designed with MultiVolt I/O capabilities, it operates with a 2.5V core voltage while interfacing seamlessly across 1.8V, 2.5V, and 3.3V logic levels. Its advanced In-System Programmability (ISP) via an IEEE 1149.1 JTAG interface makes it an optimal choice for complex glue logic, bus management, and legacy system maintenance
The EPM7512AEBI256-10 is currently In Stock and ready for immediate shipping at ICHOME. As a leading independent distributor, we ensure 100% authenticity and rapid global delivery.

Supply Chain & Procurement Insights
As a mature MAX 7000B series CPLD, primary factory lead times through direct franchised distribution channels often extend past 20–26 weeks or face End-of-Life (EOL) constraints. Demand remains steady in legacy industrial and telecommunication control systems.
Through ICHOME, global buyers can bypass standard factory lead times. We maintain a verified network of qualified inventory, conducting strict visual, electrical, and anti-counterfeiting testing protocols to ensure immediate shipping with zero risk.
Alternative & Equivalent Parts of EPM7512AEBI256-10
When facing production line stoppages or localized shortages, consider these functional or drop-in alternatives:
EPM7512BBC256-10 / EPM7512BFC256-10: Same MAX 7000B device family in a 256-pin package, differing primarily in commercial vs. industrial temperature ratings or packaging pitch.
EPM7512AEFC256-10 (MAX 7000A Family Equivalent): A 3.3V-core variant of the 512-macrocell architecture. While board power rails must be evaluated, pin layout and logic structures offer a close functional equivalent.
Applications of EPM7512AEBI256-10
Telecommunications Equipment: High-speed protocol logic mapping, line-card interface control, and bus bridging.
Industrial Automation & Control: Legacy PLC backplane expansion, motor control sequencing, and I/O logic aggregation requiring industrial temperature compliance ( -40°C to +85°C).
PCI System Integration: Expansion boards utilizing 3.3V PCI Local Bus interfaces (33MHz / 66MHz)
Medical & Test Measurement: Complex timing generator logic and multi-voltage signal translation.
What Is the Difference Between the Altera MAX 7000B Series (e.g., EPM7512B) and MAX 7000A series (e.g., EPM7512A)?
The main distinction lies in the core supply voltage (VCCINT). The MAX 7000B family operates on a 2.5V core voltage, lowering internal power consumption, whereas the MAX 7000A family operates on a 3.3V core voltage. Both families support MultiVolt I/O flexible interfacing (1.8V, 2.5V, and 3.3V) and share similar macrocell architectures, but power supply rails on the PCB must be verified before interchanging.
