Detailed Description

512-macrocell CPLD from the ispMACH 4000B series. In-system programmable. 176-pin TQFP/LQFP package (24 x 24 mm). 7.5 ns max pin-to-pin delay. 2.3 V to 2.7 V internal supply. 128 user I/O. 32 logic blocks. Commercial junction temperature 0 to 90°C. Surface-mount. Base product number LC4512.

Key Features

In-system programmable non-volatile CPLD

512 macrocells and 32 logic blocks for complex control and glue logic

128 I/O for broad interface coverage

7.5 ns max tpd for fast deterministic timing

Low internal core voltage 2.3 V to 2.7 V for reduced power

176-pin TQFP/LQFP package, 24 x 24 mm body

Surface-mount, tray packaging

Part of the proven ispMACH 4000B family

Key Advantages

Fast CPLD timing for tight control loops and interface logic

High density enables consolidation of multiple small PLDs into one device

In-system programmability simplifies updates and reduces time-to-market

Predictable timing vs. small FPGAs for easier verification

Low core voltage helps lower total system power

Large I/O count reduces the need for expander ICs

Lifecycle

Current lifecycle status is subject to change. This ispMACH 4000B family is mature but widely used. Contact Y-IC to confirm latest status

Equivalent or alternative models:

- Same family, different density: LC4128B (128 macrocells), LC4256B (256 macrocells) for smaller designs

- Same density, different grades/packages: LC4512B variants with different speed grades or temperature grades and alternate packages within the 4000B portfolio

- Newer alternatives: Lattice MachXO and MachXO2 families for designs needing modern features while retaining non-volatile, instant-on behavior
