LC4032B-75T48I

Overview

The LC4032B-75T48I is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000B family, manufactured by Lattice Semiconductor. It features 32 macrocells and 36 logic blocks, housed in a 48-pin Thin Quad Flat Package (TQFP). The device supports In-System Programmability (ISP) via JTAG and offers a maximum operating frequency of 111 MHz with a propagation delay of 7.5 ns. It operates on a single 3.3V supply voltage and includes EEPROM memory for non-volatile configuration storage.

Feature Summary

• 32 Macrocells and 36 Logic Blocks for high-density logic implementation
• In-System Programmability (ISP) support via JTAG interface
• Maximum operating frequency of 111 MHz
• EEPROM-based non-volatile configuration memory

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• State machine implementation
• Interface translation between different voltage domains

Procurement Notes

Verify RoHS compliance status as source data indicates non-compliance for this specific part number. Confirm package integrity for TQFP-48 housing. Ensure design tools support the ispMACH 4000B family architecture. Check for lead-free alternatives if environmental regulations require it.

Selection Notes

Select this component when 32 macrocells are sufficient for the design logic. The 75 speed grade provides a 7.5 ns propagation delay suitable for moderate-speed applications. Consider the TQFP-48 package constraints regarding pin count and board space compared to BGA options.

Part Context

This part belongs to the ispMACH 4000B series, which succeeded the original ispMACH 4000A family. It utilizes Lattice's SuperFast technology to optimize performance per milliwatt. The 'B' suffix denotes the specific generation within the 4000 family, offering enhanced features over earlier variants while maintaining pin compatibility.

Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the ispMACH 4000B family such as LC4032B-75VN48 or LC4032B-10T48I, provided timing requirements are met.
