ACEX 1K device package types include thin quad flat pack (TQFP), plastic quad flat pack (PQFP), and FineLine
BGA packages.
Devices in the same package are pin-compatible, although some devices have more I/O pins than others. When
planning device migration, use the I/O pins that are common to all devices.
This option is supported with a 256-pin FineLine BGA package. By using SameFrame
TM
pin migration, all FineLine
BGA packages are pin-compatible. For example, a board can be designed to support 256-pin and 484-pin FineLine
BGA packages.

General
Description
Altera
®
ACEX 1K devices provide a die-efficient, low-cost architecture by
combining look-up table (LUT) architecture with EABs. LUT-based logic
provides optimized performance and efficiency for data-path, register
intensive, mathematical, or digital signal processing (DSP) designs, while
EABs implement RAM, ROM, dual-port RAM, or first-in first-out (FIFO)
functions. These elements make ACEX 1K suitable for complex logic
functions and memory functions such as digital signal processing, wide
data-path manipulation, data transformation and microcontrollers, as
required in high-performance communications applications. Based on
reconfigurable CMOS SRAM elements, the ACEX 1K architecture
incorporates all features necessary to implement common gate array
megafunctions, along with a high pin count to enable an effective interface
with system components. The advanced process and the low voltage
requirement of the 2.5-V core allow ACEX 1K devices to meet the
requirements of low-cost, high-volume applications ranging from DSL
modems to low-cost switches.
The ability to reconfigure ACEX 1K devices enables complete testing prior
to shipment and allows the designer to focus on simulation and design
verification. ACEX 1K device reconfigurability eliminates inventory
management for gate array designs and test vector generation for fault
coverage.
Table 4
shows ACEX 1K device performance for some common designs.
All performance results were obtained with Synopsys DesignWare or
LPM functions. Special design techniques are not required to implement
the applications; the designer simply infers or instantiates a function in a
Verilog HDL, VHDL, Altera Hardware Description Language (AHDL), or
schematic design file.

Each ACEX 1K device contains an embedded array and a logic array. The
embedded array is used to implement a variety of memory functions or
complex logic functions, such as digital signal processing (DSP), wide
data-path manipulation, microcontroller applications, and data-
transformation functions. The logic array performs the same function as
the sea-of-gates in the gate array and is used to implement general logic
such as counters, adders, state machines, and multiplexers. The
combination of embedded and logic arrays provides the high
performance and high density of embedded gate arrays, enabling
designers to implement an entire system on a single device.
ACEX 1K devices are configured at system power-up with data stored in
an Altera serial configuration device or provided by a system controller.
Altera offers EPC16, EPC2, EPC1, and EPC1441 configuration devices,
which configure ACEX 1K devices via a serial data stream. Configuration
data can also be downloaded from system RAM or via the Altera
MasterBlaster
TM
, ByteBlasterMV
TM
, or BitBlaster
TM
download cables.
After an ACEX 1K device has been configured, it can be reconfigured in-
circuit by resetting the device and loading new data. Because
reconfiguration requires less than 40 ms, real-time changes can be made
during system operation.
ACEX 1K devices contain an interface that permits microprocessors to
configure ACEX 1K devices serially or in parallel, and synchronously or
asynchronously. The interface also enables microprocessors to treat an
ACEX 1K device as memory and configure it by writing to a virtual
memory location, simplifying device reconfiguration.
