Product details
Overview
AT17C002-10CI from Atmel is a 2-Mbit (2,097,152 × 1-bit) serial EEPROM FPGA configuration memory designed for in-system programming of SRAM-based FPGAs. It operates at 5V ± 10% over -40°C to +85°C, supports cascading via CEO pin, and features programmable reset polarity and system-friendly READY output. Used in industrial FPGA configuration systems requiring reliable power-up sequencing and nonvolatile program storage.
For engineers reviewing the AT17C002-10CI datasheet, AT17C002-10CI pinout, AT17C002-10CI application, or AT17C002-10CI equivalent, key selection criteria include industrial temperature support, 5V operation with standby current <0.75 mA, cascading capability for multi-FPGA systems, and compatibility with Xilinx XC4000/XC5200, Altera FLEX®, and Atmel AT40K/AT94K devices.
Technical Context
The AT17C002-10CI implements a serial-access configuration memory architecture with synchronous clock-driven address counter and open-collector DATA output. Its RESET/OE pin serves dual function-active-Low reset and active-High output enable-with polarity programmable via EEPROM bytes.
It supports two operational modes: FPGA master serial mode (SER_EN = High) and 2-wire in-system programming mode (SER_EN = Low). In master mode, CLK is driven by the FPGA CCLK; CEO output enables daisy-chained configurators, and READY provides open-collector power-on reset status indication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2,097,152 × 1-bit - stores full bitstream for mid-density SRAM FPGAs like Xilinx XC4000 or Altera FLEX 10K. |
| Supply voltage | 5V ± 10% - supports industrial-grade 4.5–5.5 V rail; compatible with legacy 5V FPGA I/O domains. |
| Operating temperature | -40°C to +85°C - qualified for industrial embedded control, motor drives, and communications infrastructure. |
| Standby current | <0.75 mA at 5V - enables low-power hold during FPGA configuration pauses or system sleep states. |
| Max clock frequency | 15 MHz - supports fast configuration loading on high-speed FPGAs without external clock division. |
| Cascading support | CEO output with automatic tri-state on end-of-data - enables seamless daisy-chain of multiple AT17C002-10CI units for >2-Mbit configurations. |
| Reset polarity | Programmable - allows alignment with FPGA INIT pin logic (active-Low default) without hardware inversion. |
Pinout & Package
AT17C002-10CI 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. The package uses surface-mount land pads (no leads); pin 1 is marked by corner chamfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | I/O (open-collector) | Bi-directional configuration data bus; tri-stated when CE or RESET/OE inactive; requires external pull-up for FPGA DIN interface. |
| CLK | Input | Synchronous clock input from FPGA CCLK; increments internal address/bit counter; minimum pulse width 20 ns. |
| RESET/OE | Input | Dual-function: active-Low reset (resets address counter) and active-High output enable; polarity programmable in EEPROM. |
| CE | Input (active-Low) | Chip enable for read operations; forces low-power standby when High; ignored during 2-wire ISP (SER_EN = Low). |
| VCC | Power supply | +5V ± 10% supply; decoupling with 0.2 µF capacitor to GND required per datasheet layout guidance. |
| SER_EN | Input | Serial enable: High for FPGA master mode; Low to enter 2-wire ISP programming mode; tied to VCC in production. |
| CEO (A2) | Output (active-Low) | Chip Enable Output signals end-of-data; used to cascade next configurator; A2 is device-select input during ISP. |
| GND | Ground | Reference ground plane connection; critical for noise immunity in high-speed configuration clock paths. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | 2-wire serial interface (SER_EN = Low) enables field firmware updates without socket removal or dedicated programmers. |
| Cascadable architecture | CEO output automatically disables DATA driver at end-of-memory and enables next device's CE, enabling scalable multi-FPGA configs. |
| System-friendly READY pin | Open-collector output driven Low during power-on reset; released after VCC stabilization - synchronizes FPGA startup with supply integrity. |
| Programmable reset polarity | EEPROM-configurable RESET/OE behavior eliminates need for external inverters when interfacing with FPGAs having inverted INIT logic. |
| Low-power standby mode | CE = High reduces ICCS to <0.75 mA - extends system-level power budget in always-on industrial controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT17LV002-10CI | 3.3V ± 10% operation; lower ICCA (5 mA vs. 10 mA); reduced FMAX (10 MHz vs. 15 MHz in military temp range) | Required for 3.3V FPGA I/O domains; not suitable for 5V-only systems or mixed-voltage boards without level-shifting. | Select AT17LV002-10CI only when target FPGA uses 3.3V configuration interface and industrial temperature support is needed. |
| XCR3256XL-10TQ144I | Nonvolatile CPLD with integrated configuration logic; no external EEPROM needed; higher pin count (144-TQFP); different programming model | Replaces both FPGA and configurator in ultra-compact designs; eliminates serial configuration timing constraints but increases design complexity. | Choose XCR3256XL-10TQ144I only for new designs targeting CPLD-based configuration consolidation-not a drop-in replacement for AT17C002-10CI. |
Compared with AT17LV002-10CI, AT17C002-10CI delivers higher speed and 5V compatibility essential for legacy FPGA platforms; versus XCR3256XL-10TQ144I, it preserves modular architecture and simplifies bitstream updates without CPLD reprogramming.

FAQ
What is the operating voltage range for AT17C002-10CI?
The AT17C002-10CI operates at 5V ± 10%, supporting 4.5 V to 5.5 V across its industrial temperature range (-40°C to +85°C). This ensures compatibility with standard 5V FPGA configuration interfaces and eliminates need for voltage translation in legacy designs using AT17C002-10CI.
How does the READY pin function in AT17C002-10CI?
The READY pin on AT17C002-10CI is an open-collector output driven Low during power-on reset and released (tri-stated) once VCC stabilizes within specification. When used with a 4.7 kΩ pull-up resistor, it provides a clean reset synchronization signal to the FPGA's INIT pin, ensuring deterministic configuration startup in AT17C002-10CI-based systems.
Can AT17C002-10CI be used in cascaded FPGA configurations?
Yes, AT17C002-10CI supports cascading via its CEO (Chip Enable Output) pin, which goes Low upon reaching end-of-memory. This signal can directly drive the CE input of the next AT17C002-10CI in a daisy-chain, enabling seamless expansion beyond 2-Mbit total configuration capacity without external logic or controllers.
Is AT17C002-10CI pin-compatible with older Atmel configuration PROMs?
AT17C002-10CI is a direct replacement for AT17C/LV020 in 8-lead LAP packages and maintains functional and pinout compatibility with AT17C002-10CC/CI variants. However, it is not pin-compatible with XC17 or ATT17 series PROMs due to differing pin assignments and signaling conventions in AT17C002-10CI.
What programming methods does AT17C002-10CI support?
AT17C002-10CI supports both offline programming using industry-standard programmers (e.g., ATDH2200E) and in-system programming (ISP) via its 2-wire serial interface when SER_EN is pulled Low. Programming occurs at nominal VCC (5V), with internal charge pumps eliminating need for external high-voltage supplies in AT17C002-10CI applications.
