Description
• IN-SYSTEM PROGRAMMABLE
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 Ac-
cess 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 intercon-
nect, to provide truly reconfigurable systems.
— 2.5V In-System Programmability (ISP™) Using
Boundary Scan Test Access Port (TAP)
— Open-Drain Output Option for Flexible Bus Interface
Capability, Allowing Easy Implementation of Wired-OR
or Bus Arbitration Logic
— Increased Manufacturing Yields, Reduced Time-to-
Market and Improved Product Quality
— Reprogram Soldered Devices for Faster Prototyping
• 100% IEEE 1149.1 BOUNDARY SCAN TESTABLE
• THE EASE OF USE AND FAST SYSTEM SPEED OF
PLDs WITH THE DENSITY AND FLEXIBILITY OF FPGAs
— Enhanced Pin Locking Capability
— Three Dedicated Clock Input Pins
— Synchronous and Asynchronous Clocks
— Programmable Output Slew Rate Control
— Flexible Pin Placement
The basic unit of logic on the ispLSI 2064VL device is the
Generic Logic Block (GLB). The GLBs are labeled A0,
A1…B7(seeFigure1). Thereareatotalof16GLBsinthe
ispLSI 2064VL device. Each GLB is made up of four
macrocells. Each GLB has 18 inputs, a programmable
AND/OR/ExclusiveORarray, andfouroutputswhichcan
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.
