Description
The ispLSI 1048 is a High-Density Programmable Logic
Device which contain 288 Registers, 96 Universal I/O
pins, ten Dedicated Input pins, four Dedicated Clock
Input pins and a Global Routing Pool (GRP). The GRP
provides complete interconnectivity between all of these
elements. The ispLSI 1048 features 5-Volt in-system
programming and in-system diagnostic capabilities. It is
the first device which offers non-volatile reprogrammability
of the logic, as well as the interconnect to provide truly
reconfigurable systems.
The basic unit of logic on the ispLSI 1048 devices 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 1048 device. Each GLB has 18 inputs, a programmable AND/OR/XOR array, and four outputs 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.

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.
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. Additionally, all outputs are
polarity selectable, active high or active low. The signal
levels are TTL compatible voltages and the output drivers
can source 4 mA or sink 8 mA.
Clocks in the ispLSI 1048 device are selected using the
Clock Distribution Network. Four dedicated clockpins
(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 on the
ispLSI 1048 device). The logic of this GLB allows the user
to create an internal clock from a combination of internal
signals within the device.
Eight GLBs, 16 I/O cells, two dedicated inputs (one
dedicated input in Megablock B and E) and one ORP are
connected together to make a Megablock (see figure 1).
The outputs of the eight GLBs are connected to a set of
16 universal I/O cells by the ORP. The ispLSI 1048
device contains six of these Megablocks.

1. One output at a time for a maximum duration of one second. Vout = 0.5V was selected to avoid test problems by tester ground
degradation. Characterized but not 100% tested.
2. Measured using twelve 16-bit counters.
3. Typical values are at VCC = 5V and TA = 25oC.
4. Maximum ICC varies widely with specific device configuration and operating frequency. Refer to the Power Consumption section of this datasheet and Thermal Management section of this Lattice Semiconductor Data Book or CD-ROM to estimate maximum

Power Consumption
Power consumption in the ispLSI 1048 device depends
on two primary factors: the speed at which the device is
operating, and the number of Product Terms used. Fig-
ure 3 shows the relationship between power and operating speed.

Notes: Configuration of Twelve 16-bit Counters
Typical Current at 5V, 25¡C
ICC can be estimated for the ispLSI 1048 using the following equation:
ICC = 73 + (# of PTs * 0.23) + (# of nets * Max. freq * 0.010) 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 ICC estimate is based on typical conditions (VCC = 5.0V, room temperature) and an assumption of 2 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.

Dedicated input pins to the device. (IN 2 and IN 9 not available)
Input – Dedicated in-system programming enable input pin. This pin
is brought low to enable the programming mode. The MODE, SDI,
SDO and SCLK options become active.
Input – This pin performs two functions. It is a dedicated input pin when
ispEN is logic high. When ispEN is logic low, it functions as an input
pin to load programming data into the device. SDI/IN 0 also is used as
one of the two control pins for the isp state machine.
Input – This pin performs two functions. It is a dedicated input pin when
ispEN is logic high. When ispEN is logic low, it functions as a pin to
control the operation of the isp state machine.
Input/Output – This pin performs two functions. It is a dedicated input
pin when ispEN is logic high. When ispEN is logic low, it functions as
an output pin to read serial shift register data.
Input – This pin performs two functions. It is a dedicated input when
ispEN is logic high. When ispEN is logic low, it functions as a clock pin
for the Serial Shift Register.
Active Low (0) Reset pin which resets all of the GLB and I/O registers
in the device.
Dedicated Clock input. This clock input is connected to one of the
clock inputs of all of the GLBs on the device.
Dedicated clock input. This clock input is brought into the clock
distribution network, and can optionally be routed to any GLB on the
device.
Dedicated clock input. This clock input is brought into the clock
distribution network, and can optionally be routed to any GLB and/or
any I/O cell on the device.
