Delta39K™ ISR™

CPLD Family

CPLDs at FPGA Densities™

Features

• High density

— 30K to 200K usable gates

— 512 to 3072 macrocells

— 136 to 428 maximum I/O pins

— Twelve dedicated inputs including four clock pins,

four global I/O control signal pins and four JTAG

interface pins for boundary scan and reconfig-

urability

Embedded memory

— 80K to 480K bits embedded SRAM

• 16K to 96K bits of (dual-port) channel memory

High speed – 233-MHz in-system operation

AnyVolt™ interface

— 3.3V, 2.5V,1.8V, and 1.5V I/O capability

Low-power operation

— 0.18-mm six-layer metal SRAM-based logic process

— Full-CMOS implementation of product term array

— Standby current as low as 5mA

• Simple timing model

— No penalty for using full 16 product terms/macrocell

— No delay for single product term steering or sharing

• Flexible clocking

— Spread Aware™ PLL drives all four clock networks

• Allows 0.6% spread spectrum input clocks

• Several multiply, divide and phase shift options

— Four synchronous clock networks per device

— Locally generated product term clock

— Clock polarity control at each register

• Carry-chain logic for fast and efficient arithmetic opera-

tions

• Multiple I/O standards supported

— LVCMOS (3.3/3.0/2.5/1.8V), LVTTL, 3.3V PCI, SSTL2

(I-II), SSTL3 (I-II), HSTL (I-IV), and GTL+

• Compatible with NOBL™, ZBT™, and QDR™ SRAMs

• Programmable slew rate control on each I/O pin

• User-programmable Bus Hold capability on each I/O pin

• Fully 3.3V PCI-compliant (to 66-MHz 64-bit PCI spec,

rev. 2.2)

• CompactPCI hot swap ready

• Multiple package/pinout offering across all densities

— 208 to 676 pins in PQFP, BGA, and FBGA packages

— Simplifies design migration across density

— Self-Boot™ solution in BGA and FBGA packages

• In-System Reprogrammable™ (ISR™)

— JTAG-compliant on-board programming

— Design changes do not cause pinout changes

• IEEE1149.1 JTAG boundary scan

•

Development Software
