AT18F002中文资料FPGA Configuration Flash Memory数据手册Microchip规格书

描述 Description

The AT18F Series of JTAG In-System Programmable Configuration PROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The AT18F Series device is packaged in a 20-lead TSSOP. The AT18F Series Configurator uses a simple serial-access procedure to
configure one or more FPGA devices.
The AT18F Series Configurators can be programmed with Atmel or industry-standard, third-party, stand-alone programmers such as BP, Data I/O, Hi-Lo, etc.

简介

AT18F002属于集成电路（IC）的用于FPGA的配置PROM。由Microchip制造生产的AT18F002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。
