LC4032ZC-35T48C

Overview

The LC4032ZC-35T48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000Z family, manufactured by Lattice Semiconductor. This automotive-grade component integrates 32 macrocells and supports up to 32 I/O pins within a TQFP-48 package. It operates with a core voltage of 1.8V for low dynamic power consumption while providing 5V-tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces. The device features JTAG In-System Programmability (ISP) and offers a maximum operating frequency (fMAX) of 400 MHz with a propagation delay (tpd) of 3.5 ns.

Feature Summary

• Automotive-grade qualification supporting junction temperatures up to +130°C
• SuperFAST performance with fMAX of 400 MHz and tpd of 3.5 ns
• 5V tolerant I/Os supporting LVCMOS 3.3, LVTTL, and PCI standards
• JTAG In-System Programmability (ISP) for flexible design updates

Applications

• Automotive electronic systems requiring high reliability and temperature stability
• Interface bridging between 5V legacy logic and 3.3V/1.8V modern components
• General-purpose digital logic implementation in industrial control environments

Procurement Notes

Verify that the specific suffix 'Z' denotes the automotive grade variant, as standard commercial versions lack the extended temperature range certification. Confirm package integrity for the TQFP-48 form factor upon receipt. Ensure ESD protection protocols are followed during handling due to the sensitivity of CMOS structures. Cross-reference the manufacturer's latest datasheet for any potential pinout or electrical specification updates prior to final board integration.

Selection Notes

Select this part when an automotive-qualified CPLD is required for designs operating in high-temperature environments. The 32 macrocell density is suitable for moderate complexity logic functions. Choose this over the standard 'V' or 'C' variants if the application demands compliance with automotive thermal specifications. Verify that the 3.5 ns speed grade meets the timing requirements of the target system architecture.

Part Context

This component is part of the ispMACH 4000Z family, which extends the capabilities of the standard ispMACH 4000 series to meet automotive industry standards. The 'Z' designation specifically indicates automotive qualification, distinguishing it from commercial counterparts like the LC4032VC or LC4032BC. It shares architectural similarities with other members of the 4000 family but is optimized for reliability under harsh thermal conditions.

Replacement Considerations

Direct functional replacements include other parts within the ispMACH 4000Z family, such as the LC4032ZC-35TN48C, provided the package type matches. For non-automotive applications, the LC4032VC-35T48C may serve as a substitute if thermal constraints allow. Verify pin compatibility and electrical characteristics before substituting with devices from other manufacturers.
