ispLSI 5000VE Description

• 100% IEEE 1149.1 BOUNDARY SCAN TESTABLE AND

3.3V IN-SYSTEM PROGRAMMABLE

The ispLSI 5000VE Family of In-System Programmable

High Density Logic Devices is based on Generic Logic

Blocks (GLBs) of 32 registered macrocells and a single

Global Routing Pool (GRP) structure interconnecting the

GLBs.

• ARCHITECTURE FEATURES

— Enhanced Pin-Locking Architecture with Single-

Level Global Routing Pool and SuperWIDE GLBs

— Wrap Around Product Term Sharing Array Supports

up to 35 Product Terms Per Macrocell

Outputs from the GLBs drive the Global Routing Pool

(GRP) between the GLBs. Switching resources are pro-

vided to allow signals in the Global Routing Pool to drive

any or all the GLBs in the device. This mechanism allows

fast, efficient connections across the entire device.

— Macrocells Support Concurrent Combinatorial and

Registered Functions

— Macrocell Registers Feature Multiple Control

Options Including Set, Reset and Clock Enable

— Four Dedicated Clock Input Pins Plus Macrocell

Product Term Clocks

— Programmable I/O Supports Programmable Bus

Hold, Pull-up, Open Drain and Slew Rate Options

— Four Global Product Term Output Enables, Two

Global OE Pins and One Product Term OE per

Macrocell

Each GLB contains 32 macrocells and a fully populated,

programmable AND-array with 160 logic product terms

and three extra control product terms. The GLB has 68

inputs from the Global Routing Pool which are available

in both true and complement form for every product term.

The 160 product terms are grouped in 32 sets of five and

sent into a Product Term Sharing Array (PTSA) which

allows sharing up to a maximum of 35 product terms for

a single function. Alternatively, the PTSA can be by-

passed for functions of five product terms or less. The

three extra product terms are used for shared controls:

reset, clock, clock enable and output enable.

to change without notice.
