AT17LV020-10JC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 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.
