描述 Description

The ATF20V8B is a high-performance CMOS (electrically erasable) programmable logic device (PLD) that utilizes Atmel’s proven electrically-erasable Flash memory technology. Speeds down to 7.5 ns and power dissipation as low as 10 mA are offered. All speed ranges are specified over the full 5V ± 10% range for industrial temperature ranges, and 5V ± 5% for commercial temperature ranges.
Several low-power options allow selection of the best solution for various types of power-limited applications. Each of these options significantly reduces total system power and enhances system reliability.
The ATF20V8Bs incorporate a superset of the generic architectures, which allows direct replacement of the 20R8 family and most 24-pin combinatorial PLDs. Eight outputs are each allocated eight product terms. Three different modes of operation, configured automatically with software, allow highly complex logic functions to be realized.

簡介

ATF20V8B-10JC屬于集成電路（IC）的PLD（可編程邏輯器件）。由制造生產的ATF20V8B-10JCPLD（可編程邏輯器件）可編程邏輯器件 (PLD) 是集成電路，其中包含能提供用戶可配置邏輯功能（AND、OR等）的相對少量功能性元件以及設備內各元件之間的可配置互連器件，從而允許實現(xiàn)適當復雜度的邏輯功能，與單獨使用各個邏輯器件相比，所需使用的元器件更少，并且還簡化了對實現(xiàn)的功能進行更改的過程。這種類型的器件通常會集成非易失性配置存儲器，從而允許在設備斷電時保留已編程的功能。
