ispLSI 5000V Description

The ispLSI 5000V 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

— 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

— Slew and Skew Programmable I/O (SASPI/O™)

Supports Programmable Bus Hold, Pull-up, Open

Drain and Slew and Skew Rate Options

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.

Each GLB contains 32 macrocells and a fully populated,

programmable AND-array with 160 logic product terms

and five extra control product terms. The GLB has 68

inputs from the Global Routing Pool which are available

— Six Global Output Enable Terms, Two Global OE

Pins and One Product Term OE per Macrocell
