Overview
The AT17C010A-10JI is a 1-Mbit serial EEPROM configurator designed for Altera FLEX devices. It operates at 5V with an industrial temperature range of -40°C to +85°C. The device supports 2-wire in-system programming and features a READY pin for power-up status indication. Available in a 20-lead PLCC package, it provides low-power CMOS operation and programmable reset polarity.
Feature Summary
- Stores configuration programs for Altera FLEX field programmable gate arrays
- Supports cascading for multiple configurations or higher-density arrays
- Features a system-friendly READY pin for simplified power-up considerations
- Allows programmable reset polarity via four EEPROM bytes
Applications
- Configuring Altera FLEX devices
- Simple interface to SRAM FPGAs
- In-system programming via 2-wire bus
Procurement Notes
Verify the specific suffix 'JI' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 20-lead PLCC package format. Confirm that the 5V supply voltage requirement aligns with your system design, as LV versions exist for 3.3V applications. Ensure compatibility with Altera FLEX device protocols before procurement.
Selection Notes
Select this component when configuring Altera FLEX devices requiring 1-Mbit storage capacity. Choose the 5V version over the LV variant if the system operates at nominal 5V. The PLCC package is suitable for surface-mount assembly where space efficiency is required. Consider cascading capabilities if single-device memory is insufficient.
Part Context
This part belongs to the AT17A Series FPGA Configuration EEPROMs, originally developed by Atmel. These devices serve as cost-effective configurators for loading field programmable gate arrays. The series includes both 512-Kbit and 1-Mbit densities with various package options including PDIP, PLCC, and TQFP.

FAQ
What is the function of the READY pin?
The READY pin is an open-collector indicator driven Low during the power-on reset cycle and released when complete.
How is the device programmed?
Programming is performed via a 2-wire serial interface by bringing the SER_EN pin Low.
