Description

— 100% Tested at Time of Manufacture

• IN-SYSTEM PROGRAMMABLE

The ispLSI 1048E is a High Density Programmable Logic

Device containing 288 Registers, 96 Universal I/O pins,

12 Dedicated Input pins, four Dedicated Clock Input pins,

twodedicatedGlobalOEinputpins,andaGlobalRouting

Pool(GRP).TheGRPprovidescompleteinterconnectivity

between all of these elements. The ispLSI 1048E offers

5Vnon-volatilein-systemprogrammabilityofthelogic,as

well as the interconnect to provide truly reconfigurable

systems. A functional superset of the ispLSI 1048 archi-

tecture, the ispLSI 1048E device adds two new global

output enable pins and two additional dedicated inputs.

— In-System Programmable (ISP™) 5V Only

— Increased Manufacturing Yields, Reduced Time-to-

Market and Improved Product Quality

— Reprogram Soldered Devices for Faster Prototyping

• OFFERS THE EASE OF USE AND FAST SYSTEM

SPEED OF PLDs WITH THE DENSITY AND FLEXIBILITY

OF FIELD PROGRAMMABLE GATE ARRAYS

— Complete Programmable Device Can Combine Glue

Logic and Structured Designs

— Enhanced Pin Locking Capability

— Four Dedicated Clock Input Pins

— Synchronous and Asynchronous Clocks

— Programmable Output Slew Rate Control to

Minimize Switching Noise

— Flexible Pin Placement

— Optimized Global Routing Pool Provides Global

Interconnectivity

The basic unit of logic on the ispLSI 1048E device is the

Generic Logic Block (GLB). The GLBs are labeled A0,

A1…F7(seeFigure1). Thereareatotalof48GLBsinthe

ispLSI 1048E device. Each GLB has 18 inputs, a pro-

grammableAND/OR/ExclusiveORarray,andfouroutputs

which can be configured to be either combinatorial or

registered. Inputs to the GLB come from the GRP and

dedicated inputs. All of the GLB outputs are brought back

into the GRP so that they can be connected to the inputs

of any other GLB on the device.

Notes: Configuration of twelve 16-bit counters,

Typical current at 5V, 25°C

I

can be estimated for the ispLSI 1048E using the following equation:

= 20 + (# of PTs * 0.42) + (# of nets * Max. freq * 0.010)

CC

Where:

# of PTs = Number of Product Terms used in design

# of nets = Number of Signals used in device

Max. freq = Highest Clock Frequency to the device

The I

CC

estimate is based on typical conditions (V

= 5.0V, room temperature) and an assumption of 4 GLB loads on

CC

average exists. These values are for estimates only. Since the value of I

is sensitive to operating conditions and the

CC

program in the device, the actual I

should be verified.

Package Thermal Characteristics

For the ispLSI 1048E-125LT, it is strongly recommended

that the actual Icc be verified to ensure that the maximum

Please refer to the Thermal Management section of the

Lattice Semiconductor Data Book or CD-ROM for addi-

J

junction temperature (T ) with power supplied is not

exceeded. Depending on the specific logic design and

clock speed, airflow may be required to satisfy the maxi-
