ISPGDX240VA-4B388

Overview

The ISPGDX240VA-4B388 is a high-density, high-performance Complex Programmable Logic Device (CPLD) belonging to the ispXDP family. It integrates 240 macrocells capable of operating at SuperFAST frequencies up to 400 MHz. The device features a 1.8V core voltage for low dynamic power consumption and supports 5V tolerant I/O standards including LVCMOS 3.3, LVTTL, and PCI interfaces. It utilizes JTAG In-System Programmability (ISP) for flexible configuration and is available in a 388-pin FineLine BGA package.

Feature Summary

• Integrates 240 macrocells with individual clock, reset, preset, and enable controls for complex logic implementation
• Supports SuperFAST performance with maximum operating frequencies reaching 400 MHz
• Features 5V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interface standards
• Utilizes a 1.8V core voltage architecture to minimize dynamic power consumption

Applications

• High-speed data acquisition systems requiring precise timing control
• PCI bus interface adapters and protocol converters
• Industrial automation controllers and programmable logic gateways
• Test and measurement equipment signal processing modules

Procurement Notes

Verify that the specific suffix 'VA' corresponds to the required automotive or extended temperature grade if operating conditions demand it. Confirm the '4' speed grade meets the target system frequency requirements of 400 MHz. Ensure the 388-pin FineLine BGA footprint matches the PCB layout constraints. Validate supply chain authenticity through authorized distributors to prevent counterfeit components.

Selection Notes

Select this component when design requirements exceed the capacity of lower-density CPLDs but do not necessitate the complexity of an FPGA. The 240 macrocell count provides sufficient resources for glue logic replacement and state machine implementation. The 388-pin package offers extensive I/O availability for systems requiring broad connectivity. Consider the 1.8V core voltage implications for power budgeting compared to older 3.3V-only devices.

Part Context

This device is part of the ispXDP family, representing a significant evolution from the legacy ispDX series. It combines the density of the ispMACH 4000 family with advanced process technology. The family targets applications needing high pin counts and reliable non-volatile configuration without the overhead of FPGA routing resources.

Replacement Considerations

Direct replacements include other members of the ispXDP family such as the ISPGDX160VA or ISPGDX512VA depending on macrocell density needs. Legacy equivalents may be found in the ispMACH 4000V/Z series, though pinouts and feature sets differ significantly.
