LC4064C-75T48I

Complex Programmable Logic Devices Overview

The LC4064C-75T48I is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000C family, manufactured by Lattice Semiconductor. It features 64 macrocells organized into 4 Logic Array Blocks (LABs) and provides 32 I/O pins within a 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It supports supply voltages ranging from 2.3 V to 2.7 V, typically 2.5 V, and functions within an industrial temperature range of -40°C to +105°C.

Complex Programmable Logic Devices Feature Summary

• High-performance architecture supporting up to 400 MHz operation with 7.5 ns propagation delay.
• Contains 64 macrocells distributed across 4 Logic Array Blocks for flexible logic implementation.
• Supports in-system programmability via JTAG interface using ispMACH technology.
• Industrial temperature rating (-40°C to +105°C) suitable for demanding environments.

Complex Programmable Logic Devices Applications

• High-speed data acquisition systems requiring fast logic processing.
• Address decoding and bus bridging in embedded computer architectures.
• State machine implementations for industrial control applications.
• Interface translation between different voltage domains or protocols.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors due to potential availability of refurbished units. Confirm RoHS compliance status as manufacturing processes may vary by production date. Check for moisture sensitivity level (MSL) handling requirements prior to soldering. Ensure design-in documentation matches the specific 'C' series revision for accurate timing parameters.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. Compare against the LC4064B series if lower power consumption is critical, noting that the C series offers improved performance characteristics. Verify pin compatibility with existing PCB footprints, as the TQFP-48 package dimensions must match the board layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C family, which succeeded the 4000B series. It utilizes Lattice's high-density PLD technology designed for replacing complex discrete logic gates. The family is characterized by non-volatile configuration memory, allowing the device to retain its program without external storage components upon power-up.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include the LC4064B-75T48I, though electrical specifications such as leakage current and speed grades may differ slightly. The LC4064Z-75T48I is an automotive-grade alternative but operates at a lower maximum frequency (168 MHz). Verify functional equivalence before substituting in safety-critical designs.
