Introduction and Overview
Introduction
The Actel Fusion Programmable System Chip (PSC)
satisfies the demand from system architects for a device
that simplifies design and unleashes their creativity. As
the world’s first mixed-signal programmable logic family,
Fusion integrates mixed-signal analog, flash memory,
and FPGA fabric in a monolithic PSC. Actel Fusion devices
enable designers to quickly move from concept to
completed design and then deliver feature-rich systems
to market. This new technology takes advantage of the
unique properties of Actel flash-based FPGAs, including a
high-isolation, triple-well process and the ability to
support high-voltage transistors to meet the demanding
requirements of mixed-signal system design.
Actel Fusion PSCs bring the benefits of programmable
logic to many application areas, including power
management, smart battery charging, clock generation
and management, and motor control. Until now, these
applications have only been implemented with costly
and space-consuming discrete analog components or
mixed-signal ASIC solutions. Actel Fusion PSCs present
new capabilities for system development by allowing
designers to integrate a wide range of functionality into
a single device, while at the same time offering the
flexibility of upgrades late in the manufacturing process
or after the device is in the field. Actel Fusion devices
provide an excellent alternative to costly and time-
consuming mixed-signal ASIC designs. In addition, when
used in conjunction with the Actel 8051 core or
ARM-based soft MCU core, Actel Fusion technology
represents the definitive PSC platform.
Flash-based Fusion devices are live at power-up. As soon
as system power is applied and within normal operating
specifications, Fusion devices are working. Fusion devices
have a 128-bit flash-based lock and industry-leading AES
decryption, used to secure programmed intellectual
property (IP) and configuration data. Actel Fusion
devices are the most comprehensive single-chip analog
and digital programmable logic solution available today.
To support this new ground-breaking technology, Actel
has developed a series of major tool innovations to help
maximize
extensions to the popular Actel Libero
Design Environment (IDE), these new tools allow
designers to easily instantiate and configure peripherals
within a design, establish links between peripherals,
create or import building blocks or reference designs,
and perform hardware verification. This tool suite will

General Description
The Actel Fusion family, based on the highly successful
ProASIC
been designed as a high-performance, programmable,
mixed-signal platform. By combining an advanced flash
FPGA core with flash memory blocks and analog
peripherals, Fusion devices dramatically simplify system
design and, as a result, dramatically reduce overall
system cost and board space.
The state-of-the-art flash memory technology offers
high-density integrated flash memory blocks, enabling
savings in cost, power, and board area relative to
external flash solutions, while providing increased
flexibility and performance. The flash memory blocks
and integrated analog peripherals enable true mixed-
mode programmable logic designs. Two examples are
using an on-chip soft processor to implement a fully
functional Flash MCU and using high-speed FPGA logic
to offer system and power supervisory capabilities. Live
at power-up and capable of operating from a single
3.3 V supply, the Fusion family is ideally suited for system
management and control applications.
The devices in the Fusion family are categorized by FPGA
core density. Each family member contains many
peripherals, including flash memory blocks, an analog-
to-digital-converter (ADC), high-drive outputs, both RC
and crystal oscillators, and a real-time counter (RTC). This
provides the user with a high level of flexibility and
integration to support a wide variety of mixed-signal
applications. The flash memory block capacity ranges
from 2 Mbits to 8 Mbits. The integrated 12-bit ADC
supports up to 30 independently configurable input
channels. The on-chip crystal and RC oscillators work in
conjunction with the integrated phase-locked loops
(PLLs) to provide clocking support to the FPGA array and
on-chip resources. In addition to supporting typical RTC
uses such as watchdog timer, the Fusion RTC can control
the on-chip voltage regulator to power down the device
(FPGA fabric, flash memory block, and ADC), enabling a
low-power standby mode.
