AT17C010-10PI

Overview

The AT17C010-10PI is a 1-megabit (1,048,576 x 1-bit) serial EEPROM designed for FPGA configuration. It operates at a nominal 5V supply voltage with a range of 4.5V to 5.5V in the industrial temperature range (-40°C to +85°C). The device features a simple 2-wire serial interface compatible with SRAM-based FPGAs like Xilinx XC3000/4000 and Atmel AT40K series. It supports In-System Programming (ISP) via a 2-wire bus and includes a system-friendly READY pin to indicate power stability. The part is housed in an 8-lead Plastic Dual Inline Package (PDIP).

Feature Summary

• Provides non-volatile storage for FPGA configuration programs with automatic loading upon power-up.
• Supports In-System Programming using a standard 2-wire serial bus interface.
• Includes a programmable reset polarity feature to match specific FPGA requirements.
• Features a READY output pin that signals valid power levels during system startup.

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration memory for Atmel AT40K and AT94K devices
• In-System Programming (ISP) of FPGA configuration data

Procurement Notes

Verify the package type corresponds to the 8-lead PDIP variant as indicated by the 'P' suffix. Confirm the operating temperature range matches the Industrial specification (-40°C to +85°C) required by the 'I' suffix. Ensure the supply voltage aligns with the 5V CMOS process characteristics defined for the AT17C series. Cross-reference the ordering code AT17C010-10PI against current manufacturer documentation to confirm availability and revision status.

Selection Notes

Select this component when a 1-megabit capacity is required for single or cascaded FPGA configuration. Choose the AT17C010-10PI over LV variants if the system design utilizes a 5V logic environment rather than 3.3V. Consider the PDIP package only if through-hole mounting is necessary; otherwise, LAP or PLCC options may be more suitable for surface mount designs. Verify compatibility with the target FPGA's master serial mode timing requirements.

Part Context

This device belongs to the AT17 Series high-density FPGA Configuration EEPROMs, which also includes the 512-kbit AT17C512 model. The series is designed to replace older PROMs and provides a cost-effective solution for programming Field Programmable Gate Arrays. The AT17C010 specifically offers double the density of the 512-kbit counterpart, supporting larger configuration arrays or daisy-chained setups.

Replacement Considerations

The AT17LV010-10PI serves as a low-voltage (3.3V) functional substitute within the same package, provided the system voltage is adjusted accordingly. Direct replacements for legacy configurations include the AT17C512 for smaller designs, though capacity differs. Verify pin compatibility across the AT17 family, as LAP, PDIP, and PLCC packages are pin-compatible within the series.
