CL8452A Laser-Configured ASIC

Description

The Clear Logic CL8000 Laser-Configured ASIC (LASIC®) family

offers the ultimate combination of performance, flexibility, and

cost. This family is a system level second source to Altera

FLEX® 8000 products. For designs not requiring in-system

reprogrammability, design verification can be performed using

the programmable Altera devices, and Clear Logic LASICs can be

used for low cost, high volume production.

Clear Logic’s innovative laser ASIC technology eliminates NRE

costs, test vector development, ordering minimums and long lead

times. No re-simulation or re-layout is required, as the device is

engineered using a cell-based, PLD-like architecture. Clear

Logic’s TestCell technology ensures complete test coverage

through the use of specialized testing modes which are

transparent to the user.

The Clear Logic CL8000 Laser-Configured ASIC family is based

upon a large array of logic elements. Each logic element contains

a configurable look up table for combinatorial functions and a

register for sequential operations. A group of eight logic

elements forms a block. Laser-configured metal fuses implement

logical functions and control signal routing

Laser configuration provides reduced cost and enhanced

performance. These inherent performance benefits include

extremely consistent propagation delays, reduced power

consumption, and improved immunity to noise and upset events.

Configuration

Clear Logic’s CL8000 LASIC® family is compatible with all six

configuration modes defined for the FLEX® 8000 product family.

These configuration modes include the following:

u Active Serial

u Active Parallel Up

u Active Parallel Down

u Passive Parallel Synchronous

u Passive Parallel Asynchronous
