LC4512V-35T176C

Complex Programmable Logic Devices Overview

The LC4512V-35T176C is a complex programmable logic device from the ispMACH 4000V family, manufactured by Lattice Semiconductor. It features 512 macrocells and supports JTAG in-system programming. The device operates with a core voltage of 1.8 V and includes 5 V tolerant I/Os for LVCMOS 3.3, LVTTL, and PCI interfaces. It is housed in a 176-LQFP package and supports an operating temperature range of 0°C to 90°C (TJ).

Complex Programmable Logic Devices Feature Summary

• Integrates 512 macrocells with individual clock, reset, preset, and clock enable controls.
• Supports SuperFAST performance frequencies up to 400 MHz.
• Features Global Routing Pool and Output Routing Pool for timing predictability and pin-out retention.
• Enables density migration across the ispMACH 4000 family.

Complex Programmable Logic Devices Applications

• System control and glue logic in computing platforms.
• Interface bridging between different voltage domains.
• Sequencing and side-channel logic in data center switches.
• Platform firmware resilience functions.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix against the required timing constraints, as the part number indicates a 35 ns delay variant. Confirm the commercial temperature grade suitability for the target environment. Ensure the design utilizes the correct 1.8 V core supply while maintaining 5 V tolerance on I/O pins. Cross-reference the 176-LQFP footprint with the manufacturer's package diagram for accurate PCB layout.

Complex Programmable Logic Devices Selection Notes

Select this component when high-density CPLD functionality is required within a small form factor. The 512 macrocell count suits moderate complexity designs needing reliable in-system reprogrammability. Consider the 5 V tolerant I/O capability if interfacing with legacy 5 V systems without level shifters. The SuperFAST architecture ensures predictable timing for synchronous designs requiring high throughput.

Complex Programmable Logic Devices Part Context

This device belongs to the ispMACH 4000V family, which blends ispLSI 2000 and ispMACH 4A architectures. It offers low dynamic power consumption due to its 1.8 V core voltage. The family provides excellent first-time-fit characteristics and supports automotive temperature ranges in specific variants, though this commercial grade unit covers standard industrial applications.

Complex Programmable Logic Devices Replacement Considerations

Devices within the same ispMACH 4000V family with compatible pinouts and higher or equal speed grades may serve as direct replacements. Verify that alternative parts maintain the 176-LQFP package dimensions and electrical specifications. Ensure any substitute supports JTAG in-system programming if field updates are required.
