AT17C010A

Features Serial EEPROM Family for Configuring Altera FLEX® 10K Devices Simple, Easy-to-use 4-pin Interface E2 Programmable 1M Bit Serial Memories Designed To Store Configuration Programs For Programmable Gate Arrays Cascadable To Support Additional Configurations or Future Higher-density Arrays Low-power CMOS EEPROM Process Programmable Reset Polarity Available in the Space-efficient Surface-mount PLCC Package In-System Programmable Via 2-Wire Bus Emulation of 24CXX Serial EPROMs Available in 3.3V ± 10% LV and 5V ± 5% C Versions Description The AT17C512/010A and AT17LV512/010A (AT17A Series) FPGA Configuration EEPROMs (Configurators) provide and easy-to-use, cost-effective configuration memory for programming Altera FLEX Field Programmable Gate Arrays, FPGA, (the “devices”). The AT17A Series is packaged in the popular 20-pin PLCC package. The AT17A Series family uses a simple serial-access procedure to configure one or more FPGA devices. The AT17A Series organization supplies enough memory to configure one or multiple smaller FPGAs. Using a special feature of the AT17A Series, the user can select the polarity of the reset function by programming an EEPROM byte. The AT17C/LV512/010A parts generate their own internal clock and can be used as a system “master” for loading the FPGA devices. The Atmel devices also supports a system friendly READY pin and a write protect mechanism. The READY pin is used to simplify system power-up considerations. The WP1 pin is...
