Mingjiada Offers INTEL EPM3512AQC208-10N in Stock: Analysis of Specifications and Features of the MAX 3000A Series 512-Macrocell CPLD

In the maintenance and mass production of industrial control systems, communication equipment, and embedded systems, discontinued CPLD models that are still in service often face procurement challenges where “they cannot be ordered from the original manufacturer and are unavailable in stock.” The Intel (formerly Altera) EPM3512AQC208-10N is precisely such a MAX 3000A series complex programmable logic device that continues to be in demand for legacy projects. Shenzhen Mingjiada Electronics Co., Ltd., as a professional supplier with extensive experience in the electronic component distribution sector, currently stocks genuine, in-stock units of this model, providing engineers and procurement professionals with a traceable and verifiable supply channel.

I. What Is the EPM3512AQC208-10N?

The EPM3512AQC208-10N belongs to the Intel/Altera MAX® 3000A series and is a complex programmable logic device (CPLD) based on EEPROM technology. This device provides 10,000 usable gates, 512 macrocells, and 172 user I/O pins. It is housed in a 208-pin PQFP package, supports in-system programming (ISP), and has a speed grade of 10 ns. Designed with non-volatile storage and “plug-and-play” functionality in mind, the MAX 3000A series is suitable for production designs with specific requirements for startup timing and configuration reliability.

III. Key Features and Design Benefits

1. EEPROM Non-Volatile Configuration, Ready to Run Upon Power-On

The MAX 3000A series utilizes EEPROM storage cells, ensuring that configuration data is retained even after power is removed. There is no need to load configuration data from external memory upon power-up, eliminating the need for a configuration chip and reducing startup wait time. For industrial field devices and communications infrastructure where equipment must enter operational status immediately upon power-up, this feature reduces uncertainties in the system startup sequence.

2. In-System Programmability (ISP), Supporting Field Updates

The device supports in-system programming via the JTAG interface, allowing logic modifications or version upgrades without removing the chip from the circuit board. For equipment already deployed in the field, ISP capability means that functional adjustments or defect fixes can be implemented through firmware updates, significantly reducing maintenance costs.

3. 3.3 V Low-Voltage CMOS Process, Balancing Speed and Power Consumption

The 3.3 V core voltage, combined with the CMOS process, achieves a maximum operating frequency of 116.3 MHz at a 10 ns latency, making it suitable for board-level designs with power consumption and switching noise constraints. The wide supply voltage range of 3 V to 3.6 V also enhances tolerance to power supply fluctuations.

4. 172 I/Os and 208-pin PQFP Pin Configuration

The 172 user I/Os in the 208-pin package provide ample signal connectivity, making it suitable for logic designs involving multi-bus interfaces, multi-channel control, and medium-scale protocol conversion. The PQFP package is compatible with the soldering processes used on most SMT production lines and facilitates rework and visual inspection.

IV. Typical Application Scenarios

The density and I/O configuration of the EPM3512AQC208-10N make it practical for use in the following scenarios:

Industrial Control and Motor Drives: As an integrated platform for logic interface bridging, PWM signal generation, and protection logic, existing engineering cases have utilized CPLDs from the same series in the design of three-phase motor control interface boards.

Communication Equipment and Base Stations: Used for address decoding, bus arbitration, interface level conversion, and timing control logic.

Embedded system glue logic: It performs functions such as chip select generation, interrupt consolidation, and peripheral interface expansion in the peripherals of MCUs or processors.

Maintenance of existing equipment and spare parts supply: For production line equipment and test instruments that have been in use for many years, this model serves as a direct replacement option while maintaining the original design.
