Product details
Overview
AT17C010-10JI from Atmel is a 1-Mbit (1,048,576 × 1-bit) serial EEPROM FPGA configuration memory with 5V ± 10% industrial supply support, programmable reset polarity, and cascading CEO output for multi-FPGA systems. It operates across –40°C to +85°C, features a system-friendly READY pin, and supports in-system programming via 2-wire bus for Xilinx XC4000/Virtex, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
For engineers reviewing the AT17C010-10JI datasheet, AT17C010-10JI pinout, AT17C010-10JI application, or AT17C010-10JI equivalent, key selection criteria include industrial temperature rating, 5V operation compatibility, cascading capability via CEO, READY pin availability, and pin-compatible packaging across LAP/PDIP/PLCC footprints.
Technical Context
The AT17C010-10JI implements a serial-access configuration memory architecture with tri-state DATA output controlled by CE and RESET/OE, internal address/bit counters auto-reset on power-up, and programmable reset polarity stored in EEPROM. Its CEO output enables daisy-chain cascading, while SER_EN selects between FPGA loading mode (High) and 2-wire ISP mode (Low).
It interfaces directly with SRAM-based FPGA master serial mode: CLK driven by FPGA CCLK, DATA fed to FPGA DIN, CEO of one device drives CE of the next, and READY provides open-collector power-good indication. Standby current is <0.5 mA at 5V when CE is high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576 × 1-bit (1-Mbit) nonvolatile EEPROM storage for full FPGA bitstream |
| Supply Voltage | 5V ± 10% - supports industrial-grade operation from –40°C to +85°C |
| Max Clock Frequency | 15 MHz - enables fast configuration loading compatible with XC4000/Virtex CCLK timing |
| Standby Current | <0.5 mA at 5V - reduces system power during FPGA idle or hold states |
| CEO Output | Active-Low chip enable output - synchronizes cascaded configuration sequencing without external logic |
| READY Pin | Open-collector power-on reset indicator - signals stable VCC to FPGA INIT or system controller |
| Reset Polarity | Programmable (RESET active Low / OE active High default) - matches Xilinx/Altera/Atmel FPGA reset conventions |
Pinout & Package
AT17C010-10JI is packaged in an 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1 mm body, pin-compatible with 8-lead SOIC/VOIC footprints. Thermal resistance θJA = 135.71°C/W (0 ft/min airflow).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DATA | Three-state bidirectional I/O - outputs configuration data to FPGA DIN; open-collector for 2-wire ISP |
| 2 | CLK | Input clock - synchronized to FPGA CCLK to increment internal address counter |
| 3 | RESET/OE | Combined input - resets address counter (active Low) and enables DATA output (active High) |
| 4 | CE | Chip Enable (active Low) - disables counters and enters standby mode when high |
| 5 | VCC | +5V power supply - supports 5V ± 10% industrial voltage range |
| 6 | SER_EN | Serial Enable - must be tied to VCC for FPGA loading; pulled low to enter 2-wire ISP mode |
| 7 | CEO (A2) | Chip Enable Output (active Low) - asserts when final bit is read; enables next cascaded device |
| 8 | GND | Ground reference - requires 0.2 µF decoupling capacitor between VCC and GND |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | 2-wire serial interface (SER_EN = Low) eliminates need for dedicated programmers during board-level rework |
| Cascadable CEO output | Enables seamless daisy-chain configuration of multiple FPGAs or higher-density bitstreams without glue logic |
| System-friendly READY pin | Open-collector signal released after power stabilization - used to gate FPGA INIT or delay system boot |
| Programmable reset polarity | EEPROM-stored setting allows field adaptation to FPGA-specific reset timing requirements (e.g., Xilinx vs. Altera) |
| Low-power standby mode | CE = High reduces current to <0.5 mA - critical for battery-backed or energy-sensitive embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Xilinx XC17V010 | 5V-only, 1-Mbit PROM; no READY pin, no programmable reset polarity, no CEO cascading | Limited to Xilinx-only ecosystems; requires external reset management and lacks daisy-chain support | Select when legacy Xilinx toolchain compatibility is mandatory and cascading is unnecessary |
| Microchip (Atmel) AT17LV010-10JI | 3.3V ± 10% operation; lower ICCA (5 mA vs. 10 mA); reduced FMAX (10 MHz vs. 15 MHz) | Targets low-voltage FPGA platforms (e.g., Virtex-E, Spartan-II); incompatible with 5V systems | Select only for 3.3V designs where power efficiency outweighs speed and voltage margin requirements |
Compared with XC17V010 and AT17LV010-10JI, the AT17C010-10JI uniquely delivers industrial 5V operation, integrated READY signaling, programmable reset, and hardware-supported cascading - making it the optimal choice for robust, multi-FPGA industrial and telecom systems requiring field-programmability and thermal resilience.

FAQ
What is the operating temperature range for the AT17C010-10JI?
The AT17C010-10JI is rated for industrial operation from –40°C to +85°C. This specification is confirmed in the "Operating Conditions" table of the official Atmel datasheet (Rev. 0944E–12/01), where VCC = 5V ± 10% is defined for the industrial grade. The device uses standard CMOS EEPROM process technology qualified across this full range.
Does the AT17C010-10JI support in-system programming (ISP)?
Yes, the AT17C010-10JI supports in-system programming via its 2-wire serial interface. When SER_EN is driven low, the device enters ISP mode and accepts programming commands on DATA and CLK pins. This capability is documented in the "Programming Mode" section and verified in Figures 3–4 of the datasheet, enabling field updates without removing the AT17C010-10JI from the board.
What is the function of the CEO pin on the AT17C010-10JI?
The CEO (Chip Enable Output) pin on the AT17C010-10JI is an active-Low signal that goes Low when the internal address counter reaches its maximum value (i.e., after the last bit is read). In cascaded configurations, CEO of one AT17C010-10JI drives the CE input of the next device, enabling automatic daisy-chain sequencing without external control logic or timing constraints.
Can the AT17C010-10JI be used with Xilinx Virtex FPGAs?
Yes, the AT17C010-10JI is explicitly listed as compatible with Xilinx Virtex FPGAs in the "Features" section of the datasheet. It supports Master Serial Mode configuration, interfaces directly with Virtex CCLK and DIN pins, and meets timing requirements including 15 MHz max clock frequency and CEO-driven cascading - all validated in Xilinx application notes referenced by Atmel.
Is the READY pin available on the AT17C010-10JI in all package types?
Yes, the READY pin is present and functional on the AT17C010-10JI in all supported packages - 8-lead LAP (8CN4), 8-lead PDIP (8P3), and 20-lead PLCC (20J). The datasheet confirms READY is available on the 20-lead PLCC (Pin 15) and notes its omission only applies to lower-density variants (AT17C/LV65/128/256), not the AT17C010-10JI.
