LC4032ZE-5TN48I

Overview

The LC4032ZE-5TN48I is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000ZE family, manufactured by Lattice Semiconductor. It features 32 macrocells and operates with a maximum frequency of 400 MHz. The device utilizes a 3.3V supply voltage and offers a typical standby current of approximately 12 µA. It supports 5V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. The component is housed in a 48-pin TQFP package and is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• ispMACH 4000ZE architecture with SuperFAST performance up to 400 MHz
• 32 macrocells with individual clock, reset, preset, and clock enable controls
• 5V tolerant I/Os supporting LVCMOS 3.3, LVTTL, and PCI standards
• Industrial temperature range (-40°C to +85°C) availability

Applications

• Interface bridging between 5V and 3.3V logic domains
• Address/data bus buffering and protocol conversion
• Glue logic for system integration and control sequencing
• Simple state machine implementations in industrial equipment

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package type is TQFP-48. Check for RoHS compliance status as per current manufacturer specifications. Ensure JTAG programming compatibility with standard ispLever or Diamond software tools.

Selection Notes

Select this model when 32 macrocells are sufficient for the design logic. The 5ns speed grade provides adequate timing margins for most interface applications. Consider the TN48 package size constraints. Compare against the V-series if lower power consumption is critical, noting potential differences in I/O drive strength or standby current.

Part Context

This part is part of the ispMACH 4000ZE family, which blends ispLSI 2000 and ispMACH 4A architectures. It serves as a drop-in replacement for older GAL and PAL devices while offering higher density and reprogrammability. The ZE series specifically targets cost-sensitive applications requiring moderate performance and low power.

Replacement Considerations

Direct pin-compatible replacements within the same family include LC4032Z-5TN48I (commercial grade) or LC4032V-5TN48I (if voltage/power specs align). Verify temperature range requirements before substituting commercial grade parts for industrial environments.
