Product details
Overview
AT17LV002-10CU from Microchip Technology (formerly Atmel) is a 2-Mbit FPGA configuration EEPROM designed to store and serially load bitstream data into SRAM-based FPGAs during power-up. It supports both 3.3V and 5.0V systems, features in-system programmability via 2-wire bus, and includes programmable reset polarity and cascading CEO output for multi-device daisy chains. Used in industrial embedded FPGA platforms requiring reliable, low-power nonvolatile configuration storage.
For engineers reviewing the AT17LV002-10CU datasheet, AT17LV002-10CU pinout, AT17LV002-10CU application, or AT17LV002-10CU equivalent, key selection criteria include its 2-Mbit density, 8-lead LAP package compatibility with SOIC footprints, dual-voltage support, cascading capability via CEO, and industrial temperature range (–40°C to +85°C).
Technical Context
The AT17LV002-10CU implements a serial EEPROM architecture optimized for FPGA master serial mode loading, using CLK-driven address incrementing and tri-state DATA output synchronized to CE/RESET/OE control. Its internal logic enables automatic counter reset on power-up and supports configurable active-low RESET/OE polarity.
It operates in two distinct modes: FPGA configuration mode (SER_EN = High), where it streams stored bitstream data to the FPGA's DIN pin under CCLK control; and ISP programming mode (SER_EN = Low), where it accepts new configuration data via 2-wire serial interface at VCC only-no external high-voltage programming required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2,097,152 × 1-bit (2 Mbit) - stores full configuration image for mid-size SRAM FPGAs like Xilinx Spartan or Altera Cyclone families. |
| Supply Voltage | 3.0 V to 5.5 V - supports mixed-voltage system integration without level-shifting for 3.3V or 5V FPGA I/O domains. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and outdoor communications equipment. |
| Max Clock Frequency | 10 MHz at 3.3V / 15 MHz at 5.0V - determines maximum FPGA configuration speed; higher frequency enables faster boot times. |
| Standby Current | 200 μA at 3.3V / 350 μA at 5.0V - enables ultra-low-power hold state when CE is high, critical for battery-backed or energy-sensitive systems. |
| Data Retention | 90 years at 85°C - ensures long-term reliability of FPGA configuration data without refresh, meeting industrial lifecycle requirements. |
| Write Endurance | 100,000 write cycles - supports field firmware updates and reconfiguration during development and maintenance phases. |
Pinout & Package
AT17LV002-10CU is packaged in an 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1.04 mm body, pin-compatible with standard 8-lead SOIC footprints. This RoHS-compliant, green (Pb/Halide-free) package uses CuNiAu finish and supports reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Three-state bidirectional data I/O | Open-collector output during FPGA configuration; used for serial data transfer to FPGA DIN; also serves as bidirectional programming data line in ISP mode. |
| CLK | Input clock | Synchronizes internal address counter and bitstream output; driven by FPGA CCLK signal; defines timing for data valid window (TCAC = 60 ns min at 3.3V). |
| WP1 | Write protect input #1 | Disables programming of protected memory blocks when pulled high; internal pull-down defaults to disabled; not used during FPGA loading. |
| RESET/OE | Programmable active-low reset / output enable | Resets address counter and tri-states DATA when low; enables DATA driver when high and CE is low; polarity is user-programmable. |
| CE | Chip enable input (active low) | Enables address counter and DATA output when low; forces device into low-power standby (200 μA) when high; does not affect 2-wire ISP mode. |
| GND | Ground reference | 0 V reference for all signals; requires 0.2 μF decoupling capacitor between VCC and GND per datasheet recommendation. |
| CEO | Chip enable output (active low) | Signals end-of-data to next device in daisy chain; drives CE of downstream AT17LV; enables seamless cascading of multiple configuration memories. |
| SER_EN | Serial enable input | Must be tied to VCC for normal FPGA configuration; pulling low enters 2-wire ISP programming mode; no external programming voltage needed. |
| VCC | Power supply | Accepts 3.0–5.5 V; powers internal EEPROM array, logic, and charge pumps; supports dual-voltage system interoperability. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability (ISP) | Enables field updates of FPGA configuration bitstreams via 2-wire serial interface without removing the device from the PCB. |
| Cascadable CEO output | Allows daisy-chaining multiple AT17LV devices to support FPGAs requiring >2 Mbit configuration memory or multi-FPGA systems. |
| Programmable reset polarity | User-configurable RESET/OE active state ensures compatibility with diverse FPGA reset architectures (e.g., Xilinx vs. Altera default behavior). |
| Dual-voltage operation | Single part supports both 3.3V and 5.0V FPGA platforms, reducing BOM count and simplifying design reuse across product generations. |
| Low-power standby mode | 200 μA max ICCS at 3.3V enables energy-efficient hold states in always-on or battery-operated FPGA-based edge devices. |

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 XC18V02 | 2-Mbit serial PROM; 3.3V-only supply; no 5.0V support; lacks WP1 and READY pins; CEO functionality limited to specific variants. | Designed exclusively for Xilinx FPGAs; less flexible for multi-vendor FPGA designs or mixed-voltage systems. | Select when targeting Xilinx-only platforms and 3.3V-only power rails; verify CEO compatibility with target FPGA family. |
| Microchip (Atmel) AT17LV002-10JU | Same 2-Mbit density and feature set; differs only in 20-lead PLCC package (20J) instead of 8-lead LAP (8CN4); identical electrical specs and timing. | Used where through-hole or larger surface-mount footprint is acceptable; PLCC offers easier prototyping and rework but higher board area cost. | Choose for manual assembly, legacy PLCC-compatible designs, or thermal dissipation needs where θJA = 90°C/W improves margin over LAP's 159.6°C/W. |
Compared with XC18V02 and AT17LV002-10JU, the AT17LV002-10CU uniquely combines dual-voltage operation, 8-lead SOIC-compatible LAP packaging, and full CEO/WP1/READY feature set-making it optimal for space-constrained, multi-vendor industrial FPGA systems requiring field programmability and long-term data integrity.

FAQ
What is the memory capacity of the AT17LV002-10CU?
The AT17LV002-10CU provides 2,097,152 × 1-bit (2 Mbit) of EEPROM storage, sufficient to configure mid-range SRAM-based FPGAs such as Xilinx Spartan-3, Altera Cyclone II, or Microsemi (Actel) IGLOO devices. This density supports typical gate counts up to ~1 million system gates with full bitstream redundancy.
Which package type does the AT17LV002-10CU use?
The AT17LV002-10CU uses an 8-lead Leadless Array Package (LAP), designated 8CN4, measuring 6 mm × 6 mm × 1.04 mm. It is pin-compatible with standard 8-lead SOIC footprints, enabling drop-in replacement in existing layouts while offering improved thermal performance and smaller footprint than PDIP or PLCC alternatives.
Does the AT17LV002-10CU support both 3.3V and 5.0V operation?
Yes, the AT17LV002-10CU supports a wide supply range of 3.0 V to 5.5 V, making it compatible with both 3.3V and 5.0V FPGA I/O standards. Electrical specifications-including VIH/VIL thresholds, VOH/VOL levels, and timing parameters-are guaranteed across this range, eliminating need for external level shifters in mixed-voltage designs.
How does cascading work with the AT17LV002-10CU?
Cascading is enabled via the CEO (Chip Enable Output) pin: when the AT17LV002-10CU completes its data stream, CEO goes low to assert CE on the next device in the chain. This allows daisy-chaining multiple AT17LV devices-e.g., two AT17LV002-10CU units provide 4 Mbit total-to support larger FPGAs or multi-FPGA configurations without external logic.
Is the AT17LV002-10CU still in active production and supported?
Yes, the AT17LV002-10CU remains in active production and is fully supported by Microchip Technology, including datasheets, application notes, and technical assistance. Unlike the NRND AT17LV65/128 variants, the AT17LV002-10CU is recommended for new designs and benefits from Microchip's long-term product longevity program.
