Description

The ispLSI 2128VE is a High Density Programmable

Logic Device available in 128 and 64 I/O-pin versions.

The device contains 128 Registers, eight Dedicated

Input pins, three Dedicated Clock Input pins, two dedi-

cated Global OE input pins and a Global Routing Pool

(GRP). The GRP provides complete interconnectivity

between all of these elements. The ispLSI 2128VE

features in-system programmability through the Bound-

ary Scan Test Access Port (TAP) and is 100% IEEE

1149.1 Boundary Scan Testable. The ispLSI 2128VE

offers non-volatile reprogrammability of the logic, as well

as the interconnect to provide truly reconfigurable sys-

tems.

The basic unit of logic on the ispLSI 2128VE device is the

Generic Logic Block (GLB). The GLBs are labeled A0, A1

.. D7 (see Figure 1). There are a total of 32 GLBs in the

ispLSI 2128VE device. 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.

Functional Block Diagram

Figure 1. ispLSI 2128VE Functional Block Diagram (128-I/O and 64-I/O Versions)

The 128-I/O 2128VE contains 128 I/O cells, while the 64-

I/O version contains 64 I/O cells. Each I/O cell is directly

connected to an I/O pin and can be individually pro-

grammed 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 4mA or sink 8mA. Each output can be

programmed independently for fast or slow output slew

rate to minimize overall output switching noise. Device

pins can be safely driven to 5V signal levels to support

mixed-voltage systems.

Eight GLBs, 32 or 16 I/O cells, two dedicated inputs and

two or one ORPs are connected together to make a

Megablock (see Figure 1). The outputs of the eight GLBs

are connected to a set of 32 or 16 universal I/O cells by

the two or one ORPs. Each ispLSI 2128VE device

contains four 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 2128VE device 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.

Programmable Open-Drain Outputs

In addition to the standard output configuration, the

outputs of the ispLSI 2128VE 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 Lattice software tools.
