EPM9320ARI208-10

Complex Programmable Logic Devices Overview

The Altera EPM9320ARI208-10 is a high-performance Complex Programmable Logic Device (CPLD) belonging to the MAX 9000 family. It features 9,320 system gates and utilizes an advanced EEPROM non-volatile configuration technology. The device operates with a single 5V supply voltage and supports in-system programmability via JTAG or parallel programming interfaces. Housed in a 208-pin Thin Quad Flat Package (TQFP), it offers robust I/O capabilities suitable for complex logic applications requiring persistent configuration without external memory.

Complex Programmable Logic Devices Feature Summary

• Utilizes MAX 9000 architecture with 9,320 system gates and 46 macrocells.
• Features non-volatile EEPROM configuration technology for instant-on operation.
• Supports In-System Programmability (ISP) via JTAG interface.
• Operates on a single 5V power supply with industrial temperature range options.

Complex Programmable Logic Devices Applications

• High-density logic replacement for legacy PLDs and PALs.
• Address decoding and bus bridging in embedded systems.
• Interface translation between different voltage domains or protocols.
• Control logic for industrial automation and instrumentation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'A' indicates the commercial temperature grade (0°C to +70°C). Confirm package integrity as the TQFP-208 form factor is sensitive to mechanical stress during handling. Check for RoHS compliance status relative to manufacturing date, as older EEPROM-based devices may have varying environmental certifications.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required to eliminate external PROMs. Ensure the design fits within the 46 macrocell limit and available I/O pins. Verify that the 5V I/O levels match the target system requirements, as mixing with lower voltage logic may require level shifting.

Complex Programmable Logic Devices Part Context

The EPM9320 is part of Altera's MAX 9000 series, designed to bridge the gap between low-density CPLDs and FPGAs. It combines the ease of use of CPLDs with the density of early FPGAs, using EEPROM for reprogrammability. This series was widely adopted before the dominance of Flash-based FPGA technologies.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to proprietary architecture. Consider Intel/Altera MAX 10 or MAX V series for modern equivalents, though these typically operate at lower voltages (1.2V/2.5V) and may require voltage translation circuits.
