LC4128ZE-7TN100C

Complex Programmable Logic Devices Overview

The LC4128ZE-7TN100C is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000ZE family. It features 128 macrocells organized into 8 Logic Array Blocks (LABs) and provides 64 I/O pins in a 100-pin TQFP package. The device operates on a 1.8V supply voltage with a maximum propagation delay of 7.5 ns and a maximum operating frequency of 260 MHz. It supports system-in-programmability via IEEE 1532 and functions within a temperature range of 0°C to 90°C.

Complex Programmable Logic Devices Feature Summary

• Enhanced routing architecture with Global Routing Pool and Output Routing Pool for improved timing predictability and first-time-fit success.
• Supports multiple interface voltages including 3.3V, 2.5V, 1.8V, and 1.5V alongside the core 1.8V supply.
• Includes advanced I/O features such as slew rate control, PCI compatibility, bus-keeper latches, and hot socketing capability.

Complex Programmable Logic Devices Applications

• High-speed digital signal processing interfaces requiring low latency.
• Bridge applications between different voltage domains or protocol converters.
• General-purpose logic replacement in industrial control systems.
• Consumer electronics requiring low power consumption and small form factor.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix codes against official Lattice documentation to confirm package type and temperature grade. Ensure compliance with RoHS directives if required by your manufacturing standards. Check for moisture sensitivity level requirements during storage and handling. Confirm availability status as product lifecycles may vary by region.

Complex Programmable Logic Devices Selection Notes

Select this component when a balance of moderate density and high speed is required. The 128 macrocell count suits simple state machines and glue logic. Consider the 7.5 ns delay for clock speeds up to 260 MHz. Evaluate pin count constraints as the 100-TQFP offers 64 usable I/Os. Compare against the standard 4000Z series if enhanced I/O features are not needed.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000ZE family, which builds upon the established 4000Z architecture. It offers improved performance and flexibility over previous generations while maintaining pin-out compatibility for many designs. The family targets applications needing reliable, low-power programmable logic with robust routing resources.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other members of the ispMACH 4000ZE family with similar macrocell counts, such as the LC4064ZE or LC4256ZE, provided pin compatibility is verified. Cross-family replacements require careful review of I/O voltage levels and timing characteristics.
