Product details
Overview
AT17LV002-10JU 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, includes programmable reset polarity, and operates across -40°C to +85°C industrial temperature range.
For engineers reviewing the AT17LV002-10JU datasheet, AT17LV002-10JU pinout, AT17LV002-10JU application, or AT17LV002-10JU equivalent, key selection criteria include cascading capability via CEO output, low-power standby current (200 µA at 3.3V), WP1 write protection, READY reset indicator, and compatibility with Xilinx Virtex®, Spartan®, and Altera APEX™ FPGAs.
Technical Context
The AT17LV002-10JU implements a serial master configuration interface for SRAM FPGAs, using CLK-driven address incrementing and tri-state DATA output synchronized to CE/RESET/OE control. Its internal EEPROM matrix stores 2,097,152 × 1-bit configuration data, accessed in strict sequential order without random addressing.
It supports daisy-chained configurations via CEO output driving CE of the next device, enables in-system programming when SER_EN is pulled low, and provides dual write protection (WP1 and RESET/OE polarity programming) - all while maintaining compatibility with industry-standard FPGA master serial mode timing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2,097,152 × 1-bit (2 Mbit) - sufficient for mid-complexity FPGA bitstreams such as Xilinx Spartan-3 or Altera Cyclone II devices. |
| 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-grade embedded FPGA applications requiring thermal robustness. |
| Standby Current | 200 µA at 3.3V - enables low-quiescent-power hold state during FPGA idle or sleep modes. |
| Max Clock Frequency | 10 MHz at 3.3V - ensures reliable configuration loading within typical FPGA CCLK timing budgets. |
| Data Retention | 90 years at 85°C - guarantees long-term bitstream integrity in thermally stressed environments. |
| Write Endurance | 100,000 cycles - supports field reprogramming for design iteration or firmware updates over product lifetime. |

AT17LV002-10JU is packaged in a 20-lead PLCC (Plastic Leaded Chip Carrier) with 1.27 mm lead pitch, JEDEC MS-018 compliant, footprint size 9.78 mm × 9.78 mm × 3.68 mm, and green (Pb/Halide-free/RoHS-compliant) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Three-state bidirectional data I/O | Open-collector output during FPGA configuration; used for serial data readback and ISP programming. |
| CLK | Configuration clock input | Synchronizes bitstream transfer; drives internal address counter and bit shift register on rising edge. |
| WP1 | Write protect input #1 | Disables write access to protected memory blocks when asserted high; internal pull-down defaults to disabled. |
| RESET/OE | Programmable active-low reset / output enable | Resets address counter and tri-states DATA when low; polarity configurable during programming. |
| CE | Chip enable input (active low) | Enables configuration readout and DATA driver when low; forces standby mode when high. |
| GND | Ground reference | Reference for all digital and analog circuitry; requires 0.2 µF decoupling capacitor to VCC. |
| CEO | Chip enable output (active low) | Signals end-of-data to cascade next EEPROM in daisy chain; driven low after final bit is read. |
| A2 | Device selection input | Used during 2-wire ISP programming to select target device; internal pull-down defaults to inactive. |
| READY | Power-on reset indicator | Open-collector output driven low during internal POR; released (high-Z) when initialization completes. |
| SER_EN | Serial enable input | Must be tied high for FPGA configuration; pulled low to enter 2-wire ISP programming mode. |
| VCC | Power supply | Accepts 3.0–5.5 V; powers EEPROM core and I/O buffers; requires local decoupling per datasheet. |

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; identical pinout and timing for Xilinx FPGA master serial mode; no WP1 or READY pins; no cascading CEO output. | Limited to Xilinx ecosystems; lacks hardware write protection and daisy-chain capability. | Select when targeting only Xilinx FPGAs and requiring minimal external components - but verify absence of WP1/CEO does not compromise system security or scalability. |
| Microchip AT17LV002-10CU | Same 2-Mbit density and functionality; differs only in package (8-lead LAP vs. 20-lead PLCC) and lead finish (CuNiAu vs. Sn). | Requires PCB redesign due to different footprint and thermal profile; LAP offers smaller area but higher soldering precision. | Choose for space-constrained designs where 6 mm × 6 mm LAP footprint is preferred and thermal management allows lower θJA (159.6°C/W vs. 90°C/W for PLCC). |
Compared with XC18V02 and AT17LV002-10CU, the AT17LV002-10JU uniquely combines industrial-temperature operation, cascading CEO, WP1 protection, and READY signaling in a rugged 20-lead PLCC package - making it optimal for multi-vendor FPGA systems requiring field update capability and robust configuration sequencing.

FAQ
What is the memory capacity and organization of the AT17LV002-10JU?
The AT17LV002-10JU contains 2,097,152 bits of EEPROM memory organized as 2,097,152 × 1-bit. It is optimized for sequential serial readout during FPGA configuration and does not support random-access addressing. This density supports mid-range FPGAs such as Xilinx Spartan-3 or Altera Cyclone II without requiring external buffering or compression.
Does the AT17LV002-10JU support daisy-chaining with other configuration EEPROMs?
Yes, the AT17LV002-10JU supports daisy-chaining via its CEO (Chip Enable Output) pin, which goes low after the final bit is read and enables the CE input of the next AT17LV device in the chain. This feature is confirmed in the datasheet for AT17LV512/010/002/040 variants and is implemented in the 20-lead PLCC package of the AT17LV002-10JU.
What is the function of the READY pin on the AT17LV002-10JU?
READY is an open-collector output that is driven low during the internal power-on reset cycle and released (tri-stated) once initialization completes. It provides a hardware-synchronized signal to the FPGA or system controller to delay configuration start until the AT17LV002-10JU is fully ready - preventing timing violations or corrupted bitstream reads during early power ramp.
Can the AT17LV002-10JU be programmed in-circuit without removal from the PCB?
Yes, the AT17LV002-10JU supports in-system programming (ISP) via its 2-wire serial interface when SER_EN is pulled low. Programming occurs at the same VCC supply voltage used for operation (3.3V or 5.0V), with internal charge pumps generating required programming voltages - eliminating need for external high-voltage sources or socketing.
What are the supported operating voltage ranges and temperature grades for the AT17LV002-10JU?
The AT17LV002-10JU operates across 3.0 V to 5.5 V supply voltage and is rated for the industrial temperature range of -40°C to +85°C. The "-10JU" suffix confirms the 20-lead PLCC package (J), industrial grade (U), and default speed grade (10). These specifications are validated per datasheet Table 10-1 and Table 10-2.
