Programmable Logic/SPLD/CPLD


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 their 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 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.
