This application note describes the differences between the ATV750B/BL PLD and the ATF750C/CL PLD, including features, packages, temperature grades, etc.

This document describes how to use the features of the ATV750 and ATV750B in the ABEL and CUPL high level description languages. The ATV750 and ATV750B are easy upgrades from a 22V10, offering twice the logic density and more flexibility in the same footprint. Both devices have 20 registers and individual clock and AR product terms for each register. Each I/O pin has a programmable polarity control and an individual output enable product term. Independent feedback paths from each register allow all of the registers to be buried without wasting the I/O pins. For the ATV750B, the registers can also be configured as D- or T-type and the clock can be selected as either a synchronous clock pin or a clock product term.

This document introduces how to use programmable logic devices as system controllers based on I/O buses

This document introduces the low-power features of Atmel PLDs, including the various density classes of Atmel PLDs and Atmel PLD's Input Transition Detection (ITD) technology. Atmel PLD's Input Transition Detection technology can significantly reduce power consumption.

This document describes how to use the features of the ATV2500 and ATV2500B in the ABEL (and Atmel- ABEL) and CUPL (and Atmel-CUPL) high level description languages. The ATV2500 and ATV2500B are the most powerful programmable logic devices available in a 40/44-pin package. They combine high density and global routing, making them easy to use and understand. Both devices have 24 macrocells, each with three sum terms, two regis- ters, and 17 product terms. Each register has individual clock and AR product terms. Each I/O pin has a programmable polarity control and an individual output enable product term. Independent feed- back paths from each register allow all of the registers to be buried without wasting the I/O pins. A universal bus routes all input and feedback signals to all product terms on all macrocells. The ATV2500B has the additional features of D- or T-type configurable registers, three dif- ferent clock options, and buried combinatorial nodes.

Atmel announced the availability of the ATF2500C, the highest density CPLD available in a 40-pin or 44-pin package. The ATF2500C is reprogrammable using Atmel's proven EE-based technology and is pin-compatible with the ATV2500B/BQ/BQL/BL which were OTP devices. The ATV2500B/BQ will be replaced by ATF2500C for commercial and industrial grade devices.

This document is an application note for ATV2500, which introduces how ATV2500 is used to incorporate multiple control or logic functions into a single programmable logic device

This article introduces the architecture of Atmel PLD products and the timing calculation methods. It also mentions the tools and software packages that design engineers can use. Atmel PLDs have deterministic and path-independent delays, which greatly simplify timing calculation.
