Lattice LC4064V75TN100-10I: A Comprehensive Technical Overview of the CPLD

The Lattice LC4064V75TN100-10I is a high-performance, low-power Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's mature ispMACH® 4000V family. Designed for a wide array of general-purpose logic integration applications, this device effectively bridges the gap between discrete logic and larger FPGAs, offering an optimal blend of density, speed, and power efficiency.

At its core, this CPLD features 64 macrocells, organized into four Function Blocks, providing ample resources for integrating numerous glue logic functions, state machines, and I/O expansion tasks. The device is built on a non-volatile, in-system programmable (ISP) architecture based on E²CMOS® technology. This foundation allows the device to be reprogrammable even after being soldered onto a circuit board, significantly accelerating development cycles and enabling field updates.

A key attribute of the -10I speed grade is its impressive timing performance. It boasts a pin-to-pin logic delay as low as 10 ns, enabling the support of high-speed logic operations and clock frequencies. This makes it suitable for applications requiring rapid signal processing and deterministic timing.

The device operates with a 1.8V core voltage, contributing to its notably low power consumption, a critical factor in modern electronic design. It also features 3.3V or 2.5V I/O banks, offering flexibility to interface with a wide range of other components in a system. The TN100 package denotes a 100-pin Thin Quad Flat Pack (TQFP), which is a surface-mount package offering a compact footprint suitable for space-constrained designs.

With 75 user I/O pins, the LC4064V75TN100-10I provides substantial connectivity for interfacing with peripherals, memory, processors, and other system components. Its I/O supports various standards like LVCMOS and LVTTL.

Target applications for this robust CPLD are extensive, including:

Power Management Sequencing and Control

System Configuration and Initialization (e.g., for FPGAs or ASICs)

I/O Expansion and Interfacing

Bus Bridging and Protocol Translation

General-Purpose Logic Consolidation
