AT18F040集成电路（IC）的用于FPGA的配置PROM规格书PDF中文资料

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.
