LC4032ZC-35M56C

Overview

The LC4032ZC-35M56C is a high-density, high-performance CPLD from the ispMACH 4000V/Z family by Lattice Semiconductor. It integrates 32 macrocells with a maximum operating frequency (fMAX) of 322 MHz and a propagation delay (tpd) of 3.5 ns. The device features a 1.8 V core voltage for low dynamic power consumption and supports 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. It utilizes JTAG In-System Programmability (ISP) and is available in a 56-pin CSBGA package with a 0.8 mm pin pitch.

Feature Summary

• High performance: fMAX up to 322 MHz and tpd of 3.5 ns
• Low power architecture: 1.8 V core voltage with typical standby current of 12 µA
• Flexible I/O: 5 V tolerant inputs supporting LVCMOS 3.3, LVTTL, and PCI standards
• In-system programmability via JTAG interface

Applications

• Industrial control systems requiring density migration
• Automotive applications supporting -40°C to +130°C junction temperature range
• Address decoding and state machine implementations using wide input gating
• Interface bridging between 5 V and 3.3 V logic domains

Procurement Notes

Verify the specific suffix 'ZC' against the manufacturer's latest datasheet to confirm the exact speed grade and temperature rating. Ensure the programming toolchain supports the ispMACH 4000V/Z family. Confirm package availability as distribution stocks vary. Check for any recent Product Change Notices regarding marking or packaging updates.

Selection Notes

Select this component when 32 macrocells are sufficient for the design logic. The 3.5 ns speed grade suits moderate-speed synchronous designs. Compare against the LC4032VC or LC4032BC variants if different voltage levels (3.3 V or 2.5 V) or higher speeds are required. Consider the CSBGA package constraints for PCB layout and thermal management.

Part Context

This part belongs to the ispMACH 4000V/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The 'Z' suffix typically denotes automotive-grade temperature ranges (-40°C to +130°C Tj). The 'C' indicates the commercial/industrial temperature range variant within that family. The '35' specifies the 3.5 ns speed bin.

Replacement Considerations

Direct functional replacements include other devices from the ispMACH 4000V/Z family with equal or greater macrocell counts, such as LC4064ZC. For lower density needs, LC4016ZC may be suitable. Verify pin compatibility if migrating between different package types like TQFP or FTBGA.
