Product details
Overview
AT17LV002-10JC from Atmel is a 2-Mbit (2,097,152 × 1-bit) serial EEPROM FPGA configuration memory supporting both 3.3V and 5.0V operation, featuring in-system programmability via two-wire bus, programmable reset polarity, and cascading capability via CEO output for multi-FPGA systems. It targets SRAM-based FPGA configuration in industrial and commercial embedded systems.
For engineers reviewing the AT17LV002-10JC datasheet, AT17LV002-10JC pinout, AT17LV002-10JC application, or AT17LV002-10JC equivalent, key selection criteria include its 2-Mbit density, 20-lead PLCC package, -40°C to +85°C industrial temperature range, CEO-driven daisy-chain support, and compatibility with Xilinx XC4000/XC5200/Spartan/Virtex and Altera FLEX/APEX FPGAs.
Technical Context
The AT17LV002-10JC implements a serial master-mode configuration interface synchronized to FPGA CCLK, using CE, RESET/OE, and CEO signals to coordinate data streaming and address counter control. Its internal architecture supports automatic power-on reset, tri-state DATA output, and programmable reset polarity stored in EEPROM bytes.
It operates in two distinct modes: FPGA loading mode (SER_EN = High), where CLK drives sequential readout, and ISP programming mode (SER_EN = Low), enabling two-wire serial write access. The CEO output enables cascaded configurations by asserting CE of the next device upon completion of its own data stream.
Key Specifications

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; 3.3 V only; no CEO output; no ISP capability; requires external programmer. | Fixed configuration only; unsuitable for field updates or daisy-chain topologies. | Select when cost-sensitive, single-use, non-upgradable FPGA designs require Xilinx-qualified memory. |
| Microchip 25LC020 | 2-Mbit SPI EEPROM; 3.3 V only; no FPGA-specific control logic (no CEO, no RESET/OE); slower max clock (5 MHz). | Lacks native FPGA interface signaling; requires FPGA-side logic to emulate configuration protocol. | Select only if existing SPI infrastructure exists and FPGA logic resources permit custom configuration controller implementation. |

FAQ
What is the memory organization of the AT17LV002-10JC?
The AT17LV002-10JC contains 2,097,152 bits organized as 2,097,152 × 1-bit. It does not support byte-wide or word-wide addressing; data is streamed serially under FPGA clock control. This linear bitstream format matches the native configuration requirements of Xilinx and Altera SRAM FPGAs, eliminating address translation logic.
Does the AT17LV002-10JC support in-system programming (ISP)?
Yes, the AT17LV002-10JC supports ISP via its two-wire serial interface when SER_EN is driven low. Programming occurs at standard VCC voltage (3.3 V or 5.0 V); no external high-voltage supply is needed. Internal charge pumps generate required programming voltages, enabling field updates without device removal.
Which FPGA families is the AT17LV002-10JC compatible with?
The AT17LV002-10JC is explicitly compatible with Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex families, as well as Altera FLEX and APEX devices. Compatibility is achieved through direct pin mapping to FPGA CCLK, DIN, and configuration control signals-no FPGA-side IP core or firmware modification is required.
What is the function of the CEO pin on the AT17LV002-10JC?
The CEO (Chip Enable Output) pin on the AT17LV002-10JC goes active-low after the final configuration bit is output, signaling completion to the next device in a daisy chain. It connects directly to the CE input of the subsequent AT17LV002-10JC (or compatible device), enabling seamless cascaded configuration without external timing logic or FPGA intervention.
Can the AT17LV002-10JC operate at both 3.3 V and 5.0 V?
Yes, the AT17LV002-10JC supports dual-voltage operation: 3.3 V ±10% and 5.0 V ±10% (industrial). Voltage selection is automatic-no mode pins or configuration registers are required. This allows one AT17LV002-10JC variant to serve both legacy 5 V and modern 3.3 V FPGA platforms, simplifying inventory and design reuse.
