AT17C010-10CI

Overview

The AT17C010-10CI is a 1-Mbit (1,048,576 x 1-bit) serial EEPROM configurator designed for FPGA configuration. It operates at 5V nominal with an industrial temperature range of -40°C to +85°C. The device supports In-System Programming via a 2-wire bus and interfaces directly with SRAM FPGAs using a simple serial access procedure. Key features include programmable reset polarity, a system-friendly READY pin for power-up indication, and low-power standby mode consuming less than 0.5 mA. It is available in 8-lead LAP, 8-lead PDIP, and 20-lead PLCC packages.

Feature Summary

• Supports In-System Programming via 2-wire serial bus
• Provides direct interface to SRAM-based FPGA devices
• Features programmable reset polarity for system flexibility
• Includes open-collector READY pin for power status indication

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT40K and AT94K FPGAs
• Drop-in replacement for legacy PROMs in Lucent ORCA applications

Procurement Notes

Verify the specific package variant required, as the 'CI' suffix denotes the Industrial temperature range (-40°C to +85°C). Confirm whether the 8-lead LAP, PDIP, or 20-lead PLCC form factor matches the target PCB footprint. Ensure the design utilizes a 5V supply rail, as this part is not compatible with 3.3V logic levels unlike the LV series. Check for availability of programming tools if ISP functionality is needed.

Selection Notes

Select this component when a high-density 1-Mbit configuration memory is required for SRAM-based FPGAs. Choose the AT17C010-10CI over the 512-kbit version if the FPGA bitstream exceeds 512 kilobits. Opt for the 'C' (5V) variant over 'LV' (3.3V) if the system operates on standard 5V rails. Consider cascading capabilities if larger memory arrays are necessary beyond the single-device capacity.

Part Context

This device belongs to the AT17 Series of FPGA Configuration EEPROMs, also known as Configurators. It is functionally compatible with earlier Atmel AT6000, AT40K, and AT94K devices, as well as emulation of Atmel's AT24CXXX serial EEPROMs. The series allows for flexible integration into various FPGA ecosystems by supporting master serial mode and daisy-chaining for expanded memory requirements.

Replacement Considerations

AT17C010-10PC (PDIP package), AT17C010-10JC (PLCC package), AT17LV010-10CI (3.3V version).
