SX-A Family FPGAs
General Description
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.
