LC4032V-10TN48I

Overview

The LC4032V-10TN48I is a complex programmable logic device (CPLD) from the Lattice ispMACH 4000V family. It contains 32 macrocells and supports up to 48 I/O pins in a TQFP-48 package. The device operates with a 3.3 V supply voltage and features SuperFAST architecture for high performance, achieving a maximum frequency of 400 MHz. Key electrical parameters include a maximum propagation delay of 10 ns, a setup time of 1.8 ns, and a typical standby current of 11.3 µA. It offers 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces.

• 5 V tolerant I/Os for LVCMOS 3.3, LVTTL, and PCI interface compatibility
• JTAG In-System Programmable (ISP) capability

Applications

• High-speed data acquisition systems
• Protocol conversion and bridging applications
• Complex glue logic replacement
• Industrial control system interfaces

Procurement Notes

Verify the specific suffix 'TN48I' corresponds to the TQFP-48 package, commercial temperature grade (-0 to +70 °C), and industrial speed grade (-10). Confirm RoHS compliance status via the manufacturer's latest documentation before procurement.

Selection Notes

Select this component when a low-power CPLD with 32 macrocells and 48 I/Os is required. Ensure the design utilizes a 3.3 V core voltage. Verify that the 10 ns propagation delay meets the timing requirements of the target application compared to faster variants like the -7 or -5 speed grades.

Part Context

This part belongs to the ispMACH 4000V family, which blends ispLSI 2000 and ispMACH 4A architectures. It is designed for applications requiring high density, low power consumption, and excellent timing predictability through Global Routing Pool technology.

Replacement Considerations

Direct replacements within the same family include LC4032V-7TN48I (faster speed) or LC4032Z-10TN48I (different voltage options). Cross-family migration to MachXO series requires re-evaluation of architecture differences.
