描述 Description

A high-performance, high-density complex programmable logic device (CPLD) with Atmel's proven electrically-erasable technology. With 32 logic macrocells and up to 36 inputs, the device easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. Enhanced routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications.The device has up to 32 bi-directional I/O pins and four dedicated input pins, depending on the type of device package selected. Each dedicated pin can also serve as a global control signal, register clock, register reset or output enable. Each of these control signals can be selected individually within each macrocell.

簡(jiǎn)介

ATF1502ASV屬于集成電路（IC）的CPLD（復(fù)雜可編程邏輯器件）。由制造生產(chǎn)的ATF1502ASVCPLD（復(fù)雜可編程邏輯器件）CPLD 是用于執(zhí)行邏輯運(yùn)算和信息處理的用戶可配置集成電路產(chǎn)品；與 PLD 或 PAL 器件相比，這些器件具有更高級(jí)別的功能（即更多的邏輯門），但低于 FPGA。CPLD 通常包含非易失性配置存儲(chǔ)器，支持直接在器件上存儲(chǔ)和保留用戶所需的配置，并在器件斷電時(shí)仍可保留這些信息。
