The basic unit of logic on these devices is the Generic
Logic Block (GLB). The GLBs are labeled A0, A1 .. D7
(Figure 1). There are a total of 32 GLBs in the ispLSI 2128
and 2128A devices. Each GLB is made up of four
macrocells. Each GLB has 18 inputs, a programmable
AND/OR/Exclusive OR 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
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.
SE
is
The device also has 128 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,
output or bi-directional I/O pin with 3-state control. The
signal levels are TTL compatible voltages and the output
drivers can source 4 mA or sink 8 mA. Each output can
be programmed independently for fast or slow output
slew rate to minimize overall output switching noise.
U
Clocks in the ispLSI 2128 and 2128A devices are selected using the dedicated clock pins. Three dedicated
clock pins (Y0, Y1, Y2) or an asynchronous clock can be
selected on a GLB basis. The asynchronous or Product
Term clock can be generated in any GLB for its own clock.
Eight GLBs, 32 I/O cells, two dedicated inputs and two
ORPs are connected together to make a Megablock
(Figure 1). The outputs of the eight GLBs are connected
to a set of 32 universal I/O cells by the two ORPs. Each
ispLSI 2128 and 2128A device contains four 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 eight 16-bit counters.
3. Typical values are at VCC = 5V and TA = 25°C.
4. Maximum I CC varies widely with specific device configuration and operating frequency. Refer to the Power Consumption
section of this data sheet and the Thermal Management section of the Lattice Semiconductor Data Book or CD-ROM

ICC can be estimated for the ispLSI 2128/A using the following equation:
FO
ICC (mA) = 20 + (# of PTs * 0.48) + (# of nets * Max freq * 0.009)
28
E
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)
21
The ICC estimate is based on typical conditions (VCC = 5.0V, room temperature) and an assumption of two 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.

Active Low (0) Reset pin which resets all of the GLB
registers in the device.
Dedicated Clock inputs. These clock inputs are connected
to one of the clock inputs of all the GLBs on the device.
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. When ispEN is logic
low, it functions as an input pin to load programming data
into the device. SDI is also used as one of the two control
pins for the isp state machine. When ispEN is high, it
functions as a dedicated input pin.
Input - This pin performs two functions. When ispEN is logic
low, it functions as a clock pin for the Serial Shift Register.
When ispEN is high, it functions as a dedicated input pin.
Input - This pin performs two functions. When ispEN is logic
low, it functions as pin to control the operation of the isp
state machine. When ispEN is high, it functions as a
dedicated input pin.
Output/Input - This pin performs two functions. When ispEN
is logic low, it functions as the pin to read the isp data.
When ispEN is high, it functions as a dedicated input pin.
