Product details
Overview
AT17LV002-10SC from Microchip Technology (formerly Atmel) is a 2-Mbit serial FPGA configuration EEPROM designed to store and load bitstream data for SRAM-based FPGAs in master serial mode. It supports both 3.3V and 5.0V operation, features programmable reset polarity, cascading via CEO output, and offers 100,000 write cycles with 90-year data retention at 85°C (industrial grade). It interfaces directly with Xilinx XC3000/XC4000/Spartan/Virtex, Altera FLEX/APEX, and Atmel AT40K/AT94K devices.
For engineers reviewing the AT17LV002-10SC datasheet, AT17LV002-10SC pinout, AT17LV002-10SC application, or AT17LV002-10SC equivalent, key selection criteria include its 2-Mbit density, 20-lead SOIC package, industrial temperature range (–40°C to +85°C), cascading capability via CEO, and dual-voltage support - all critical for reliable FPGA configuration in embedded control, industrial automation, and telecom infrastructure designs.
Technical Context
The AT17LV002-10SC implements a serial address counter driven by an external FPGA-provided clock (CLK), with tri-state DATA output controlled by CE and RESET/OE. Its CEO output enables daisy-chain configuration of multiple EEPROMs, where the completion signal from one device triggers the next in sequence.
It operates in two distinct modes: FPGA loading mode (SER_EN = High) and ISP programming mode (SER_EN = Low), using a two-wire bus. The device supports programmable reset polarity and includes dedicated write-protect inputs (WP1, WP2) active only during programming, not during FPGA configuration.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect | Reserved; must be left floating or tied to GND per layout guidelines - no internal connection. |
| 2 (DATA) | Bi-directional I/O | Open-collector output during FPGA load; bidirectional for ISP programming - requires external pull-up for proper logic levels. |
| 3 (NC) | No-connect | Unused pin; electrically isolated - no routing or termination required. |
| 4 (CLK) | Input | Driven by FPGA CCLK; increments internal address counter on rising edge - timing-critical path requiring controlled impedance trace. |
| 5 (NC) | No-connect | Not bonded; no internal function - leave unconnected. |
| 6 (RESET/OE) | Input | Active-Low reset / active-High output enable; polarity programmable - determines FPGA initialization behavior and DATA driver activation. |
| 7 (NC) | No-connect | Unused; no internal circuitry - omit from PCB layout. |
| 8 (CE) | Input | Active-Low chip enable; disables address counter and forces DATA into high-Z when high - used for power management and multi-device selection. |
| 9 (GND) | Power | Digital ground reference; requires local 0.2 µF decoupling capacitor to VCC for noise suppression. |
| 10 (CEO) | Output | Active-Low cascade enable; goes low when last bit is read - drives CE of next EEPROM in daisy chain to enable sequential loading. |

| 16 (SER_EN) | Input | Serial enable; high for FPGA load mode, low for ISP programming - must be tied to VCC unless in-system programming is required. |
| 17 (NC) | No-connect | No internal connection - leave unconnected. |
| 18 (NC) | No-connect | Unused; no function - exclude from design. |
| 19 (VCC) | Power | 3.3V or 5.0V supply input; requires local 0.2 µF ceramic decoupling capacitor to GND for stable operation. |
| 20 (NC) | No-connect | Not connected internally - no routing needed. |

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 density, 3.3V-only operation, 8-pin SOIC package, no CEO output or cascading support. | Lacks daisy-chain capability and dual-voltage flexibility; limited to Xilinx-only ecosystems. | Select when designing exclusively for Xilinx platforms with fixed 3.3V rails and no requirement for multi-device configuration chains. |
| Microchip (Atmel) AT17LV002-10JI | Same 2-Mbit density and functionality, but in 20-lead PLCC package instead of SOIC - different footprint and thermal resistance (θJA = 90°C/W vs. 150°C/W for SOIC). | PLCC offers better mechanical robustness and thermal dissipation in high-vibration environments but requires larger PCB area. | Choose for industrial applications where vibration resistance and higher thermal margin outweigh space constraints. |
Compared with XC18V02 and AT17LV002-10JI, the AT17LV002-10SC provides unique value through its 20-lead SOIC footprint (space-efficient yet hand-solderable), dual-voltage compatibility, and integrated CEO for seamless FPGA daisy chaining - making it optimal for compact, multi-FPGA industrial control systems requiring field-upgradable configuration.

FAQ
What is the maximum clock frequency supported by the AT17LV002-10SC during FPGA configuration?
The AT17LV002-10SC supports up to 15 MHz at 3.3V (commercial) and 10 MHz at 3.3V (industrial), or 15 MHz at 5V (industrial). This allows full 2-Mbit configuration in under 133 ms at 15 MHz, meeting fast-boot requirements for real-time industrial systems. Timing margins must be verified against the specific FPGA's CCLK specification and PCB trace length.
Does the AT17LV002-10SC require external pull-up resistors on its DATA and READY pins?
Yes - the AT17LV002-10SC's DATA pin is open-collector and requires an external pull-up resistor (typically 4.7 kΩ to VCC) to ensure valid logic-high levels during FPGA read operations. Similarly, the READY pin is open-collector and needs a 4.7 kΩ pull-up to monitor power-on reset completion before enabling downstream logic.
Can the AT17LV002-10SC be used to configure Xilinx Virtex-II FPGAs?
Yes - the AT17LV002-10SC is explicitly listed as compatible with Xilinx Virtex™ FPGAs in its datasheet. It supports Virtex-II master serial mode via standard CLK/DATA/CE/RESET/OE signaling, and its 2-Mbit capacity matches typical Virtex-II configuration requirements for medium-complexity designs.
How does the CEO pin function in a daisy-chain configuration with multiple AT17LV002-10SC devices?
In a daisy chain, the CEO pin of the first AT17LV002-10SC goes low upon reading its final bit, enabling the CE input of the second AT17LV002-10SC. This ensures sequential, glitch-free loading without external sequencing logic. All devices share the same CLK and DATA lines, with CEO-to-CE interconnection forming the control backbone of the chain.
Is the AT17LV002-10SC pin-compatible with earlier Atmel AT17LV series devices like the AT17LV512?
No - the AT17LV002-10SC uses a 20-lead SOIC package (20S2) with pin assignments distinct from the 8-lead packages of AT17LV65/128/256/512. While functionally similar, pin mapping differs significantly (e.g., CEO appears on pin 10 in 20S2 but is absent in 8-lead variants), requiring dedicated PCB layout.
