AT17C020数据手册集成电路（IC）的用于FPGA的配置PROM规格书PDF

描述 Description

The AT17C020 and AT17LV020 (high-density AT17 Series) FPGA Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The AT17 Series is packaged in the popular 20-pin PLCC. The AT17 Series family uses a simple serial-access procedure to configure one or more FPGA devices. The AT17 Series organization supplies enough memory to configure one or multiple smaller FPGAs. The user can select the polarity of the reset function by programming internal EEPROM bytes. These devices also support a system-friendly READY pin, which signifies a “good” power level to the FPGA and can be used to ensure reliable system power-up.
The AT17 Series Configurators can be programmed with industry-standard programmers or Atmel’s ATDH2200E Programming System.

简介

AT17C020属于集成电路（IC）的用于FPGA的配置PROM。由制造生产的AT17C020用于 FPGA 的配置 PROM配置 PROM（可编程只读存储器）是 FPGA 的配套器件，用于在设备断电期间为用户存储所需的 FPGA 配置。具体所用存储技术各不相同，包括可以电擦除和重写的类型，因此将这些器件的特征描述为“只读”有些过时。
