EPM9320RC208-15

Complex Programmable Logic Devices Overview

The EPM9320RC208-15 is a high-density programmable logic device from the Altera MAX 9000 family. It utilizes second-generation MAX architecture with EEPROM-based non-volatile configuration, eliminating the need for external configuration memory. The device offers 640 usable macrocells and supports up to 208 pins in an RQFP package. It features 5.0-V in-system programmability via JTAG and operates within a commercial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based non-volatile configuration for instant-on operation without external PROM
• 5.0-V In-System Programmability (ISP) through IEEE Std. 1149.1 JTAG interface
• Built-in JTAG boundary-scan test circuitry for manufacturing and field testing
• Programmable macrocells with individual clear, preset, clock, and clock enable controls

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Complex address decoding and bus interfacing
• State machine implementation for communication protocols
• General-purpose digital logic integration requiring non-volatile storage

Complex Programmable Logic Devices Procurement Notes

This component is classified as a legacy or discontinued product by Altera. Availability is restricted to surplus distributors or secondary markets. Verification of authenticity and physical condition is critical due to the age of the inventory. Ensure that the specific speed grade (-15) matches the timing requirements of the target design before procurement.

Complex Programmable Logic Devices Selection Notes

Select this device when a high pin count (up to 208) and significant logic density (640 macrocells) are required in a single package. It is suitable for designs needing immediate power-up functionality without external configuration chips. Compare against the MAX 7000S series if lower gate counts suffice, or consider Cyclone devices for newer SRAM-based FPGA architectures with embedded memory.

Complex Programmable Logic Devices Part Context

The EPM9320RC208-15 belongs to the MAX 9000 family, which succeeded the MAX 7000 series. It provides higher density and improved performance while maintaining the benefits of EEPROM technology. This family bridges the gap between low-density CPLDs and complex FPGAs, offering a robust solution for mid-range logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary MAX architecture. Potential alternatives include other MAX 9000 variants with compatible I/O counts or modern Cyclone IV/V devices, though these require SRAM configuration memory and different programming flows.
