Description

The LC4256V-75TN144-10 is an electronic component model in the IC Chips product category. It belongs to the ispMACH 4000 family from Lattice, which offers a SuperFAST CPLD solution. This family combines the best features of Lattice's two most popular architectures, the ispLSI® 2000 and ispMACH 4A, to provide high performance and low power consumption in a flexible CPLD family.

Specifications and features

The LC4256V-75TN144-10 has the following specifications and features:

• High performance with a maximum operating frequency (fMAX) of 400MHz and a propagation delay (tPD) of 2.5ns.
• Up to four global clock pins with programmable clock polarity control.
• Up to 80 programmable term (PT) per output.
• Enhanced macrocells with individual clock, reset, preset, and clock enable controls.
• Fast path, SpeedLockingTM Path, and wide-PT path for efficient design.
• Low power consumption with typical static current of 10µA (ispMACH 4000Z) and 1.3mA (ispMACH 4000C).
• Support for multiple temperature ranges (-40 to 130°C junction) and various supply voltages (3.3V, 2.5V, or 1.8V).
• Easy system integration with 5V tolerant I/O, hot-socketing, open-drain capability, and input pull-up/pull-down/bus-keeper options.
• Support for IEEE 1149.1 boundary scan testing and 3.3V/2.5V/1.8V In-System Programmability (ISP™) using IEEE 1532 compliant interface.
• Lead-free package options.

Application Scenarios

The LC4256V-75TN144-10 is an ideal electronic component for power-sensitive consumer applications, thanks to its low power consumption and superior performance. It can operate with 3.3V, 2.5V, or 1.8V LVCMOS I/O and supports LVCMOS 3.3, LVTTL, and PCI interfaces. It is also suitable for applications requiring fast counters, state machines, and address decoders due to its wide input gating.
