M4A3-512/192-10FAI

Complex Programmable Logic Devices Overview

The M4A3-512/192-10FAI is a member of the Lattice ispMACH 4A family, a high-performance E2CMOS Complex Programmable Logic Device (CPLD). It features 512 macrocells and supports up to 192 user I/Os. The device operates at a maximum frequency of 125 MHz with a propagation delay of 7.5 ns. It utilizes EEPROM storage technology for non-volatile configuration. The component is designed for commercial temperature ranges and offers flexible architecture with guaranteed fixed timing through SpeedLocking technology.

Complex Programmable Logic Devices Feature Summary

• High-density logic: 512 macrocells with 192 available I/O pins.
• Speed performance: 7.5 ns maximum propagation delay and 125 MHz operating frequency.
• Architecture: Central switch matrix ensures 100% routability and pin-out retention.
• In-system programmability: Supports JTAG (IEEE 1149.1) programming via 3.3-V or 5-V interfaces.

Complex Programmable Logic Devices Applications

• Complex digital logic replacement in industrial control systems.
• Address decoding and bus bridging in mixed-voltage environments.
• State machine implementation requiring guaranteed fixed timing delays.
• Prototyping and design verification using JTAG boundary scan testing.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix '10FAI' against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm availability status as older CPLD families may have limited supply or end-of-life notifications. Ensure compatibility with existing PCB footprints for the fpBGA package option.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require high I/O counts (up to 192) within a single CPLD. The 7.5 ns speed grade is suitable for moderate-speed synchronous applications. Consider the 1:1 macrocell-to-I/O ratio for efficient resource utilization compared to lower-density variants. Verify that the system voltage requirements align with the 3.3-V core operation.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A family, which bridges the gap between traditional PAL devices and FPGAs. The family emphasizes ease of use with First-Time-Fit capabilities. The M4A3-512 variant represents the highest density in the standard 3.3-V series, offering significant logic capacity for complex embedded applications.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 512 macrocell count and 192 I/O limit. Check for updated speed grades (e.g., -12 or -14) if higher performance is needed. Verify package compatibility if substituting with other fpBGA or BGA options from the same family.
