Product details
Overview
AT17LV002-10JI 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 industrial-grade FPGA configuration in SRAM-based logic designs.
For engineers reviewing the AT17LV002-10JI datasheet, AT17LV002-10JI pinout, AT17LV002-10JI application, or AT17LV002-10JI equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), 20-lead PLCC package compatibility, CEO-driven daisy-chain support, standby current of 150 µA (industrial), and verified interoperability with Xilinx XC4000/XC5200, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
Technical Context
The AT17LV002-10JI implements a serial master-configuration interface synchronized to an external FPGA CCLK signal, using CE, RESET/OE, and CEO signals to manage address counter enablement, reset behavior, and inter-device chaining. Its internal architecture supports automatic power-on reset and tri-state DATA output control without external logic.
It operates in two distinct modes: FPGA loading mode (SER_EN = High) for direct configuration readout, and two-wire ISP programming mode (SER_EN = Low) enabling field updates. The device uses on-chip charge pumps for internal programming voltage generation, eliminating need for external VPP.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Xilinx XC18V02 | 2-Mbit serial PROM; supports only 3.3V operation; no CEO pin; requires external pull-ups on DATA/CLK; not ISP-capable | Limited to Xilinx-only ecosystems; no cascading support; incompatible with 5V systems | Select when targeting Xilinx-only designs with strict 3.3V rail and no field update requirement |

FAQ
What is the memory capacity and organization of the AT17LV002-10JI?
The AT17LV002-10JI provides 2,097,152 × 1-bit (2 Mbit) serial EEPROM memory organized as a single linear array. This capacity is optimized to store full configuration bitstreams for mid-range SRAM FPGAs such as Xilinx XC5200 or Altera FLEX 10K devices. The device does not support byte-wide access or partial reconfiguration-its architecture is strictly serial, bit-sequential, and FPGA-master-mode oriented.
Does the AT17LV002-10JI support in-system programming (ISP), and how is it enabled?
Yes, the AT17LV002-10JI supports in-system programming via its two-wire serial interface. ISP is activated by driving the SER_EN pin Low while applying valid VCC (3.3V or 5V). During ISP mode, the device accepts programming commands through the DATA and CLK pins using industry-standard protocols compatible with Atmel's ATDH2225 ISP Cable or third-party programmers. The AT17LV002-10JI does not require external VPP voltage-the internal charge pump generates all necessary programming voltages.
What package type and pin count does the AT17LV002-10JI use, and is it RoHS-compliant?
The AT17LV002-10JI uses a 20-lead PLCC (Plastic Leaded Chip Carrier) package (JEDEC MS-018, Variation AA), with 1.27 mm lead pitch and body dimensions of 10.0 mm × 10.0 mm × 3.9 mm. It is RoHS-compliant and halide-free, meeting Pb-free and green packaging requirements per Atmel's ordering code suffix 'J' (industrial) and 'I' (temperature grade). Lead finish is matte tin over nickel underplate.
How does the CEO pin function in daisy-chained AT17LV002-10JI configurations?
In daisy-chained configurations, the CEO (Chip Enable Output) pin of one AT17LV002-10JI goes Low when its internal address counter reaches the final memory location. This CEO signal drives the CE (Chip Enable) input of the next AT17LV002-10JI in the chain, automatically enabling its DATA output to continue bitstream delivery. This hardware-level handoff eliminates timing-critical FPGA logic or external sequencing circuitry, enabling scalable multi-FPGA systems with deterministic startup behavior.
What are the key electrical differences between AT17LV002-10JI and the lower-density AT17LV512-10JI?
The AT17LV002-10JI draws 150 µA standby current (5V industrial), versus 100 µA for AT17LV512-10JI; it supports higher maximum clock frequency (15 MHz vs. 12.5 MHz at 3.3V industrial); and includes both WP1 and WP2 write-protect inputs (AT17LV512-10JI has only WP1). Both share identical 20-lead PLCC packaging, CEO functionality, and industrial temperature rating, but AT17LV002-10JI's larger memory enables configuration of more complex FPGAs without external memory expansion.
