LC4512B-75TN176C

Complex Programmable Logic Devices Overview

The LC4512B-75TN176C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000BV family manufactured by Lattice Semiconductor Corporation. It features 32 macrocells and 512 usable macrocells for logic implementation, supporting up to 128 I/O pins. The device operates within a supply voltage range of 3V to 3.6V and offers a maximum propagation delay of 7.5 ns. It is housed in a 176-LQFP package with dimensions of 24x24 mm and supports system-in-programmability. The component is rated for an operating temperature range of 0°C to 90°C (TJ).

• Supports System-In-Programmability (SIP) for flexible updates.
• High-density I/O capability with up to 128 input/output pins.
• Operates on a single 3.0V to 3.6V power supply.

Complex Programmable Logic Devices Applications

• Protocol conversion and bridging between different data standards.
• Address decoding and bus interfacing in embedded systems.
• State machine implementation for control logic.
• Glue logic replacement in legacy system designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'B' against official Lattice documentation to confirm it denotes the commercial temperature grade variant within the 4000BV family. Ensure the ordering part number matches the exact package type (176-TQFP) and speed grade (-75) required for the design timeline. Cross-reference with the manufacturer's current product selector guide as older series may have end-of-life notifications or pin-compatible alternatives available.

Complex Programmable Logic Devices Selection Notes

Select this component when a design requires moderate logic density (512 macrocells) with a high number of I/Os (up to 128) in a standard surface-mount package. The 7.5 ns speed grade is suitable for mid-frequency applications where lower power consumption than FPGAs is preferred. Compare against the LC4512V series if industrial temperature ranges (-40°C to +85°C) are required instead of the commercial range specified here.

Complex Programmable Logic Devices Part Context

This CPLD is part of the Lattice ispMACH 4000 family, designed to replace complex discrete logic gates. The 4000BV series specifically targets cost-sensitive applications requiring non-volatile configuration and low standby power. It serves as a bridge between high-performance FPGAs and simple GAL devices, offering reprogrammability without the complexity of FPGA bitstream management.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package include other members of the LC4512 family such as the LC4512V-75TN176C, provided the temperature grade difference is acceptable. Verify electrical characteristics and timing parameters before substitution.
