LC4032ZC-35MN56C

Overview

The LC4032ZC-35MN56C is a high-performance Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V family manufactured by Lattice Semiconductor. This device integrates 32 macrocells and supports SuperFAST™ operation with a maximum frequency of 400 MHz. It features a 1.8 V core voltage for low dynamic power consumption while maintaining 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. The component utilizes JTAG In-System Programmability and is housed in a 56-pin MiniMiniQFP package.

Feature Summary

• Integrates 32 macrocells with a propagation delay (tpd) of 2.5 ns and setup time (ts) of 1.8 ns.
• Supports SuperFAST™ performance up to 400 MHz with enhanced macrocell controls for clock, reset, preset, and enable.
• Features 5 V tolerant I/Os allowing compatibility with LVCMOS 3.3, LVTTL, and PCI standards.
• Operates with a 1.8 V core voltage and includes JTAG In-System Programmability (ISP).

Applications

• High-speed interface bridging and protocol conversion.
• Address decoding and state machine implementation.
• General-purpose logic replacement in industrial and consumer electronics.

Procurement Notes

Verify the specific speed grade suffix '35' against official datasheets to confirm timing characteristics. Ensure the package designation 'MN56' corresponds to the MiniMiniQFP form factor. Confirm that the 'C' temperature grade meets the operational requirements of the target environment before procurement.

Selection Notes

Select this model when 32 macrocells are sufficient for the design complexity. The 400 MHz fmax capability suits applications requiring fast combinatorial or registered logic paths. Consider the 5 V tolerant I/O feature if interfacing directly with legacy 5 V systems without level shifting.

Part Context

This part belongs to the ispMACH 4000V family, which blends ispLSI 2000 and ispMACH 4A architectures. The family offers Global Routing Pool and Output Routing Pool structures to ensure excellent first-time-fit rates and timing predictability. It serves as a drop-in replacement for older GAL devices in many designs.

Replacement Considerations

Within the same density class, the LC4032 variants offer different speed grades and packages. For pin-compatible alternatives, compare LC4032 models with different suffixes. Higher density options in the family include LC4064, LC4128, and LC4256.
