ISPLSI2064VL-100LT100 FPGAs Overview

The ispLSI 2064VL is a High Density Programmable Logic Device available in 64 and 32 I/O-pin versions. The device contains 64 Registers, four Dedicated Input pins, three 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 2064VL features in-system programmability through the Boundary Scan Test Access Port (TAP) and is 100% IEEE 1149.1 Boundary Scan Testable. The ispLSI 2064VL 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 2064VL device is the Generic Logic Block (GLB). The GLBs are labeled A0, A1…B7 (see ISPLSI2064VL-100LT100 Datasheet). There are a total of 16 GLBs in the ispLSI 2064VL 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.

The 64-I/O 2064VL contains 64 I/O cells, while the 32- I/O version contains 32 I/O cells. Each I/O cell is directly connected to an I/O pin and can be individually programmed to be a combinatorial input, output or bi-directional I/O pin with 3-state control 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. Device pins can be safely driven to 3.3V 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 ISPLSI2064VL-100LT100 Datasheet). The outputs of the eight GLBs are connected to a set of 32 or 16 universal I/O cells by two or one ORPs. Each ispLSI 2064VL device contains two 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 2064VL 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.
