Overview
The AT17LV010A-10JC is a 1-Mbit (1,048,576-bit) serial EEPROM configurator designed for FPGA configuration. It operates on a 3.3V supply with ±10% tolerance or a 5.0V supply with ±5% commercial and ±10% industrial tolerances. The device features a maximum access time of 10 ns and supports In-System Programming via a 2-wire bus. It is housed in a 20-lead Plastic Leaded Chip Carrier package.
Feature Summary
- Designed to store configuration programs for Altera FLEX and APEX FPGAs
- Supports In-System Programming via a 2-wire bus
- Features programmable reset polarity and cascadable read-back capabilities
- Emulates Atmel’s AT24CXXX serial EEPROMs
Applications
- Configuration memory for Altera FLEX and APEX FPGAs
- Configuration memory for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs
- Configuration memory for Lucent ORCA and Motorola MPA1000 FPGAs
Procurement Notes
Verify the specific voltage variant and temperature range required for your application. Confirm that the 20-lead PLCC package matches your PCB footprint. Ensure programming equipment supports the 2-wire serial interface for ISP operations if applicable.
Selection Notes
Select this part when a 1-Mbit capacity is needed for FPGA configuration. Choose the JC suffix for commercial temperature ranges and the 20-lead PLCC package. Consider cascading multiple units if larger configuration arrays are required.
Part Context
This component belongs to the AT17A series of FPGA configuration EEPROMs. These devices provide cost-effective configuration memory solutions. The series includes various densities from 64-Kbit to 2-Mbit, all sharing pin compatibility across the product family.

FAQ
How is the reset polarity configured?
The user can program the polarity of the RESET/OE function by writing to four specific EEPROM bytes during the programming process.
What is the purpose of the nCASC pin?
The nCASC pin goes Low when the address counter reaches its maximum value, allowing it to drive the nCS input of the next configurator in a daisy-chain sequence.
