General Description

SX-A Family FPGAs

Introduction

The Actel SX-A family of FPGAs offers a cost-effective,

single-chip solution for low-power, high-performance

designs. Fabricated on 0.22 μm / 0.25 μm CMOS

antifuse technology and with the support of 2.5 V,

3.3 V and 5 V I/Os, the SX-A is a versatile platform to

integrate designs while significantly reducing time-

to-market.

SX-A Family Architecture

The SX-A family’s device architecture provides a unique

approach to module organization and chip routing that

satisfies performance requirements and delivers the most

optimal register/logic mix for a wide variety of

applications.

Interconnection between these logic modules is achieved

using Actel’s patented metal-to-metal programmable

antifuse interconnect elements (Figure 1-1). The

antifuses are normally open circuit and, when

programmed, form a permanent low-impedance

connection.

Note: The A54SX72A device has four layers of metal with the antifuse between Metal 3 and Metal 4. The A54SX08A, A54SX16A, and

A54SX32A devices have three layers of metal with the antifuse between Metal 2 and Metal 3.
