Product details
Overview
AT17LV002A-10JU from Microchip Technology (formerly Atmel) is a 2-Mbit serial EEPROM FPGA configuration memory designed to store and load bitstreams into SRAM-based FPGAs including Altera FLEX/APEX, Xilinx Spartan/Virtex, and ORCA devices. It supports dual-voltage operation (3.3V ±10% or 5.0V ±10%), features in-system programmability via 2-wire interface, and delivers 90-year data retention at 85°C. Its primary role is master-serial mode bootloading in industrial embedded systems.
For engineers reviewing the AT17LV002A-10JU datasheet, AT17LV002A-10JU pinout, AT17LV002A-10JU application, or AT17LV002A-10JU equivalent, key selection criteria include cascading capability via nCASC, programmable reset polarity, WP1-enabled partial write protection, low-power standby current (≤150 µA @ 3.3V), and PLCC-20 package compatibility with legacy FPGA design flows.
Technical Context
The AT17LV002A-10JU operates as a dedicated serial configuration memory in master-serial mode, interfacing directly with FPGA control pins (DCLK, nCS, RESET/OE) without external controller intervention. Its internal address counter advances on DCLK rising edges only when nCS is low and RESET/OE is high, enabling deterministic bitstream delivery.
Cascading is supported through the nCASC output, which asserts low upon completion of its 2,097,152-bit sequence to enable the next device in chain; this feature is confirmed for AT17LV002A and absent in NRND variants. SER_EN must be tied high during FPGA loading and pulled low only for ISP programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2,097,152 × 1-bit (2-Mbit); sufficient to configure mid-range FPGAs like Altera EPC2 or Xilinx XC4000XL families. |
| Supply Voltage | 3.0–5.5 V; enables drop-in use in both 3.3V and 5V legacy industrial systems without level-shifting. |
| Standby Current | ≤150 µA @ 3.3V; minimizes system power budget during FPGA configuration idle states. |
| Data Retention | 90 years at 85°C; validated for long-life industrial deployments requiring unattended operation. |
| Write Endurance | 100,000 cycles; supports field firmware updates and reconfiguration in maintenance workflows. |
| Max Clock Frequency | 10 MHz @ 3.3V; ensures reliable timing margin for FPGA DCLK-driven configuration across temperature range. |
| Operating Temp | −40°C to +85°C; qualified for extended industrial environments without derating. |
Pinout & Package
AT17LV002A-10JU is packaged in a 20-lead Plastic Leaded Chip Carrier (PLCC-20), RoHS-compliant, with 1.27 mm pitch and JEDEC MS-018 AA compliance. Thermal resistance θJA = 90°C/W enables passive cooling in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Three-state bidirectional I/O | Drives FPGA DIN during configuration; open-collector for wired-OR daisy-chain support. |
| DCLK | Input/Output clock | Rising edge increments address counter; driven low by device when reset or cascade complete. |
| WP1 | Input (write protect) | Enables block-level write protection; internal pull-down defaults to unprotected state. |
| RESET/OE | Input (dual-function) | Programmable polarity: active-low reset or active-high output enable; controls DATA tristate and counter reset. |
| nCS | Input (chip select) | Active-low enable for counter and DATA; determines master/slave role in cascaded chains. |
| nCASC | Output (cascade select) | Active-low signal indicating end-of-data; connects to nCS of next device in daisy-chain. |
| A2 | Input (device select) | Used during ISP programming to select device; internal pull-down ensures default disable. |
| READY | Output (power-on indicator) | Open-collector low during power-up reset; released after VCC stabilization (requires 4.7kΩ pull-up). |
| SER_EN | Input (serial enable) | High = FPGA loading mode; Low = 2-wire ISP programming mode; tie to VCC for normal operation. |
| VCC / GND | Power / reference | Supports 3.3V or 5V supply; 0.2 µF decoupling capacitor recommended between VCC and GND. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | 2-wire serial interface (SER_EN-controlled) enables field reprogramming without socket removal. |
| Cascadable architecture | nCASC output allows daisy-chaining multiple AT17LV002A-10JU units to support >2-Mbit FPGA configurations. |
| Programmable reset polarity | User-configurable RESET/OE logic polarity via EEPROM bytes-critical for Altera vs. Xilinx FPGA compatibility. |
| Partial write protection | WP1 pin enables hardware-level protection of lower memory blocks during partial reconfiguration sequences. |
| Low-power standby | Consumes ≤150 µA @ 3.3V when nCS is high-reduces quiescent power in always-on industrial controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT17LV010A-10JU | 1-Mbit density (half capacity); identical pinout, voltage, timing, and feature set. | Targeted at smaller FPGAs (e.g., Xilinx XC3000, Altera EPC1); insufficient for Virtex or large APEX devices. | Select when configuration image size is <1 Mbit and cost optimization is prioritized over future scalability. |
| Xilinx XC18V02 | 2-Mbit density, 3.3V-only operation, JTAG-compatible programming interface, different pinout (20-pin SOIC). | Designed specifically for Xilinx FPGA ecosystems; lacks nCASC and WP1; requires JTAG programmer instead of 2-wire ISP. | Choose only for Xilinx-only designs where JTAG infrastructure exists and cascading is unnecessary. |
Compared with AT17LV010A-10JU, the AT17LV002A-10JU doubles configuration capacity while maintaining full pin and functional compatibility; versus XC18V02, it offers broader FPGA vendor support, cascading, and simpler 2-wire ISP-but requires PLCC-20 footprint and dual-voltage design allowance.

FAQ
What is the maximum clock frequency supported by AT17LV002A-10JU during FPGA configuration?
The AT17LV002A-10JU supports a maximum input clock frequency of 10 MHz when operating at 3.3V ±10%, and 15 MHz at 5.0V ±10%. These values are specified in Table 10-6 of the datasheet and ensure setup/hold timing margins for reliable bitstream transfer to SRAM-based FPGAs. Exceeding these frequencies may cause configuration errors or data corruption in the AT17LV002A-10JU.
Does AT17LV002A-10JU support JTAG programming?
No, the AT17LV002A-10JU does not support JTAG programming. It uses a dedicated 2-wire serial interface activated by pulling SER_EN low. This is explicitly stated in Note 4 of Section 11.2 of the datasheet. JTAG-capable alternatives like Xilinx XC18V02 require different programming infrastructure and are not functionally interchangeable with AT17LV002A-10JU.
Can AT17LV002A-10JU be used in a daisy-chain configuration with other AT17LVxxxA devices?
Yes, AT17LV002A-10JU supports cascading via its nCASC output pin, which goes low upon completion of its 2-Mbit sequence to enable the next device in chain. This feature is confirmed in Tables 1-1 and 1-2 and Sections 6 and 10-5 of the datasheet. It is compatible with other AT17LV512A/010A/002A devices but not with NRND variants (AT17LV65A/128A/256A) which lack nCASC.
What is the purpose of the WP1 pin on AT17LV002A-10JU?
The WP1 pin on AT17LV002A-10JU provides hardware-level write protection for designated memory blocks during ISP programming. When asserted high, it prevents writes to the lowest memory segment; it is disabled by default due to an internal pull-down resistor. Unlike the WP pin on smaller variants, WP1 is present only on AT17LV512A/010A/002A and enables selective reconfiguration without risking corruption of critical boot code stored in lower addresses.
Is AT17LV002A-10JU compatible with both 3.3V and 5V FPGA systems?
Yes, AT17LV002A-10JU is fully compatible with both 3.3V and 5V systems, supporting supply voltages from 3.0V to 5.5V. Its I/O thresholds (VIH ≥2.0V, VIL ≤0.8V) and output drive strength (VOH ≥2.4V @ 3.3V, ≥3.6V @ 5.0V) ensure interoperability with mixed-voltage FPGA interfaces. This dual-voltage capability is highlighted in the Features section and Table 10-1 of the AT17LV002A-10JU datasheet.
