Microchip Technology Inc


The Microchip EPLD product line comprises two major categories: simple programmable logic devices (SPLDs) and the higher density complex programmable logic devices (CPLDs).

Microchip SPLDs: Industry Standard

The Microchip SPLD products consist of industry standard 16V8 and 22V10s in a variety of voltage and power-saving options. Microchip offers low-voltage, zero-power and quarter power versions as well as our proprietary "L" automatic power down low-power devices including the Battery Friendly ATF22LV10CQZ. All popular packages are supported in addition to the Microchip-only, TSSOP package -- the smallest package offered for any SPLD device. All versions are EE-based for high-reliability and easy re-programming and are supported by all popular third party programmers.


Microchip CPLDs: Industry Standard Compatible

The ATF15xxAS/ASL/ASV/ASVL CPLD family offers pin-compatible supersets of the popular Altera 7000 and 3000 series devices ranging from 32 to 128 macrocells with propagation delays from 7.5 to 15 ns for 5V standard power versions and 15 ns for 3.3V versions. Microchip's proprietary low-power ("L") versions use Input Transition Detection (ITD) to power down the device automatically when nothing is switching. All devices also support JTAG in-system programming (ISP).

The Logic Doubling™ features of the ATF15xx family make these products ideal for new designs. The ATF15xx family offers the most powerful switch matrix and routing resources of any CPLD while also supporting multiple independent feedbacks, individual output enable, global clear and D/T/latch configurable flip-flops. More global clock pins, a programmable pin-keeper and the ability to realize two latches per macrocell are further examples of the enhanced features available from this CPLD product family.

Microchip CPLDs can be used for I/O expansion as well as for memory, control and Interfacing with different types of memories such as compact Flash or mobile SDRAM.

Converting an Altera EPM7000 series design is easy with Microchip's push button POF2JED software utility that will generate an industry standard JEDEC programming file from an Altera POF file. An Application note "ATF15xx Product Family Conversion" provides details of the conversion process. The POF2JED software is available at no charge.


Proprietary CPLDs

Microchip also offers the ATF750C/CL and ATF2500C CPLDs which have unique architecture that enables one to pack in more logic in a fully interconnected manner. The ATF750C has twice the logic of a standard 22V10 in a pin-out compatible 24- or 28-pin package. The ATF750C is ideal for those 22V10 designs that need a bit more logic than is offered in a 22V10 device, but need to maintain the 22V10 pin-out. The ATF2500C is a very high-density (2500 usable gates) 44-pin CPLD, ideally suitable for the most difficult 44-pin designs. The ATF2500C (electrically erasable) replaced the ATV2500B/BQ/BQL/BL in commercial, industrial and military temperature grade offerings.

Software Tools

WinCUPL - A complete, easy-to-use, Windows based design software for all Microchip SPLDs and CPLDs. It supports CUPL design entry, functional simulation, and includes the latest Fitter technologies.
CPLD - Industry Standard Compatible

ProChip Design - A full-featured EDA suite with state-of-the-art, Mentor Graphics synthesis and simulation tools integrated into a user-friendly design environment. The software supports VHDL and Verilog design flows for the ATF15xx family of complex programmable logic devices. This suite also includes a JTAG in-system programming utility and fitter technologies to enable logic doubling in ATF15xx CPLDs. Optional add-on tools support schematic and CUPL design flows.

ATMISP - In-System Programming (ISP) software for the ATF15xx family of CPLDs with JTAG support. It is to be used with the ATDH1150PC/VPC/USB or compatible programming cable to program the target CPLDs. It can also be used to generate SVF files needed by an ATE to program the ATF15xx on a circuit board.

POF2JED - The ATF15xx Conversion Utility helps in converting POF files to JEDEC files.

BSDL - Boundary scan description language (BSDL) files for the ATF15xx CPLDs with IEEE Std. 1149.1 JTAG support.

Hardware Tools
CPLD - Industry Standard Compatible

ATF15xx-DK3-U - The development/programmer kit supports the ATF15xxAS/ASL/ASV/ASVL family of 3.3V, and 5.0V industry-standard, pin-compatible CPLDs with Logic Doubling™. This kit includes a USB Based ISP cable (ATDH1150USB), a 44-TQFP adapter module, and ATF15xxAS/ASV samples in a 44-TQFP package. Adapter modules that support the 44-PLCC, 84-PLCC, and 100-TQFP packages are available separately and the 44-TQFP adapter module can also be purchased separately.

ATDH1150USB- The Microchip ATF15xx CPLD USB-based JTAG ISP Download Cable connects to a standard USB port on a PC and to a 10-pin or 14-pin JTAG header on the programming circuit board. It transfers the JTAG instructions and data generated by the ATMISP software running on a PC to the Microchip ATF15xx series CPLDs on the target circuit board. With this In-System Programming (ISP) download cable, design changes can easily be downloaded directly to the ATF15xx JTAG devices, resulting in easy prototyping of designs.
