Description

The ispLSI 1048EA is a High Density Programmable
Logic Device containing 288 Registers, 96 Universal I/O
pins, eight Dedicated Input pins, four Dedicated Clock
Input pins, two dedicated Global OE input pins, and a
Global Routing Pool (GRP). The GRP provides complete
interconnectivity between all of these elements. The
ispLSI 1048EA features 5V in-system programmability
and in-system diagnostic capabilities via IEEE 1149.1
Test Access Port. The ispLSI 1048EA offers non-volatile
reprogrammability of the logic, as well as the intercon-
nect to provide truly reconfigurable systems. A functional
superset of the ispLSI 1048 architecture, the ispLSI
1048EA device adds user selectable 3.3V or 5V I/O and
open-drain output options.

The basic unit of logic on the ispLSI 1048EA device is the
Generic Logic Block (GLB). The GLBs are labeled A0,
A1...F7 (see Figure 1). There are a total of 48 GLBs in the
ispLSI 1048EA device. Each GLB has 18 inputs, a
programmable AND/OR/Exclusive OR array, and four
outputs which can be configured to be either combinato-
rial 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.

Functional Block Diagram

Figure 1. ispLSI 1048EA Functional Block Diagram

The device also has 96 I/O cells, each of which is directly
connected to an I/O pin. Each I/O cell can be individually
programmed to be a combinatorial input, registered
input, latched input, output or bi-directional
I/O pin with 3-state control. The signal levels are TTL
compatible voltages and the output drivers can source
2mA or sink 8mA. Each output can be programmed
independently for fast or slow output slew rate to
minimize overall output switching noise. By connecting
the VCCIO pin to a common 5V or 3.3V power supply,
I/O output levels can be matched to 5V or 3.3V compat-
ible voltages.

Eight GLBs, 16 I/O cells, dedicated inputs (if available)
and one ORP are connected together to make a
Megablock (Figure 1). The outputs of the eight GLBs are
connected to a set of 16 universal I/O cells by the ORP.
Each ispLSI 1048EA device contains six Megablocks.

The GRP has, as its inputs, the outputs from all of the
GLBs and all of the inputs from the bi-directional I/O cells.
All of these signals are made available to the inputs of the
GLBs. Delays through the GRP have been equalized to
minimize timing skew.

Clocks in the ispLSI 1048EA device are selected using
the Clock Distribution Network. Four dedicated clock pins
(Y0, Y1, Y2 and Y3) are brought into the distribution
network, and five clock outputs (CLK 0, CLK 1, CLK 2,
IOCLK 0 and IOCLK 1) are provided to route clocks to the
GLBs and I/O cells. The Clock Distribution Network can
also be driven from a special clock GLB (D0). The logic
of this GLB allows the user to create an internal clock
from a combination of internal signals within the device.

Programmable Open-Drain Outputs

In addition to the standard output configuration, the
outputs of the ispLSI 1048EA are individually program-
mable, either as a standard totem-pole output or an
open-drain output. The totem-pole output drives the
specified Voh and Vol levels, whereas the open-drain
output drives only the specified Vol. The Voh level on the
open-drain output depends on the external loading and
pull-up. This output configuration is controlled by a pro-
grammable fuse. The default configuration when the
device is in bulk erased state is totem-pole configuration.
The open-drain/totem-pole option is selectable through
the ispDesignEXPERT software tools.

ispLSI 1048EA Timing Model

Specifications

ispLSI 1048EA

0127/1048EA

Icc can be estimated for the ispLSI 1048EA using the following equation:

Icc = 20mA + (# of PTs * .45) + (# of nets * Max Freq * .0087)

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 (in MHz)

The Icc estimate is based on typical conditions (Vcc = 5.0V, room temperature) and an assumption of four GLB
loads on average exists. These values are for estimates only. Since the value of Icc is sensitive to operating
conditions and the program in the device, the actual Icc should be verified.

Power Consumption

Power consumption in the ispLSI 1048EA device de-
pends on two primary factors: the speed at which the
device is operating and the number of Product Terms

used. Figure 4 shows the relationship between power
and operating speed.

Package Thermal Characteristics

For the ispLSI 1048EA-170, it is strongly recommended
that the actual Icc be verified to ensure that the maximum
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-

mum allowable junction temperature (T

) specification.

Please refer to the Thermal Management section of the
Lattice Semiconductor Data Book or CD-ROM for addi-
tional information on calculating T
