AT17C512A-10JC

Overview

The AT17C512A-10JC is a 512-Kbit serial EEPROM configurator designed for Altera FLEX devices. It operates at 5V nominal supply voltage and supports commercial temperature range (0°C to +70°C). The device is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package. It features an internal oscillator for master mode configuration, programmable reset polarity, and a READY pin for power-up status indication.

Feature Summary

• Serial interface for direct FPGA configuration without external controllers
• Internal clock generation for master mode operation
• Programmable reset polarity via EEPROM bytes
• READY pin indicates power-on reset completion

Applications

• Configuration of Altera FLEX devices
• In-system programming via 2-wire bus
• Cascadable read-back for higher-density arrays

Procurement Notes

Verify the specific ordering suffix matches the required package and temperature grade. Confirm the manufacturer origin as Atmel or Microchip Technology depending on the production era. Ensure the component meets the intended voltage and environmental specifications for the target application design.

Selection Notes

Select this part for Altera FLEX FPGA configuration needs requiring 512-Kbit capacity. Choose the PLCC package for surface-mount assembly compatibility. Consider the LV variant if 3.3V operation is required instead of the standard 5V version.

Part Context

This component belongs to the high-density AT17A Series of FPGA Configuration EEPROMs. It provides a cost-effective solution for storing configuration programs for Field Programmable Gate Arrays. The series supports simple serial-access procedures and is compatible with industry-standard programmers.

Replacement Considerations

AT17LV512A-10JC for 3.3V operation. AT17C010A-10JC for 1-Mbit capacity. Altera EPC1441 is a functional equivalent for 512-Kbit density applications.
