Product details
Overview
AT17LV65-10NI from Microchip Technology (formerly Atmel) is a 64-Kbit serial EEPROM FPGA configuration memory designed for reliable, in-system programmable storage of SRAM-based FPGA bitstreams. It supports dual-voltage operation (3.3V ±10% or 5.0V ±5%/±10%), features programmable reset polarity, and delivers 100,000 write cycles with 90-year data retention at 85°C industrial temperature range.
For engineers reviewing the AT17LV65-10NI datasheet, AT17LV65-10NI pinout, AT17LV65-10NI application, or AT17LV65-10NI equivalent, this device is selected for FPGA master serial mode boot reliability, low-power standby (<100 µA at 3.3V), cascading compatibility (via CE/RESET/OE control), and drop-in replacement for legacy AT17LV65 variants in industrial-grade embedded reconfigurable systems.
Technical Context
The AT17LV65-10NI implements a simple serial-access interface synchronized to an external FPGA CCLK signal, with direct CE, RESET/OE, and DATA pin mapping to standard SRAM FPGA configuration control logic. Its internal address counter auto-resets on power-up and responds to active-Low RESET/OE pulses to synchronize bitstream loading.
It operates exclusively in Master Serial mode - no external controller required - and uses a two-wire ISP programming interface (SER_EN low) compatible with industry-standard programmers. The device lacks CEO output and READY pin, distinguishing it from higher-density AT17LV family members and limiting it to single-device configuration chains.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – DATA | I/O (Open-collector, bi-directional) | Serial data path for FPGA DIN input during configuration; tri-stated when RESET/OE high or CE high |
| 2 – CLK | Input | FPGA CCLK-synchronized clock input that increments internal address/bit counter; requires clean edge timing |
| 3 – RESET/OE | Input | Active-Low reset + active-High output enable; polarity programmable; resets address counter and controls DATA driver state |
| 4 – CE | Input (active Low) | Chip enable that gates CLK-driven counting and DATA output; high level forces low-power standby mode |
| 5 – GND | Power ground | Reference for all I/O and internal logic; requires local 0.2 µF decoupling capacitor to VCC |
| 6 – SER_EN | Input | Serial programming enable; must be tied to VCC for normal FPGA boot; pulled low only during ISP programming |
| 7 – VCC | Power supply | Single-supply input supporting 3.3V or 5V operation; tolerates ±10% variation at industrial temp |
| 8 – WP | Input (active High) | Write protect for lowest memory block during ISP; disabled by default (internal pull-down); unused during FPGA load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT17LV65-10NC | Same 64-Kbit density, identical pinout and electrical specs, but rated for Commercial (0°C to +70°C) temperature range | Not suitable for industrial environments requiring extended temperature operation | Select AT17LV65-10NI when operating ambient exceeds 70°C or requires full industrial qualification |
| AT17LV128-10NI | 128-Kbit capacity, same 8-lead SOIC package and industrial rating, but adds CEO output and supports cascading | Enables daisy-chained multi-FPGA configurations; not pin-compatible due to CEO pin presence on AT17LV128 | Choose AT17LV128-10NI only if system requires >64 Kbit or multi-device chaining; AT17LV65-10NI remains optimal for single-FPGA cost-sensitive designs |
Compared with AT17LV65-10NC, the AT17LV65-10NI provides guaranteed operation down to –40°C and longer data retention at elevated temperatures. Against AT17LV128-10NI, it offers lower cost and simpler layout for single-FPGA systems but lacks CEO-driven cascading capability.

FAQ
What is the primary function of the AT17LV65-10NI in an FPGA system?
The AT17LV65-10NI serves as a dedicated serial configuration memory that stores and delivers bitstream data to SRAM-based FPGAs (e.g., Xilinx XC4000, Altera FLEX) during power-up or reset. It operates in Master Serial mode, eliminating the need for an external controller, and interfaces directly with FPGA control pins (CCLK, DIN, INIT) using its DATA, CLK, and RESET/OE signals. The AT17LV65-10NI ensures deterministic, repeatable FPGA initialization in industrial environments.
Does the AT17LV65-10NI support cascading with other configuration EEPROMs?
No, the AT17LV65-10NI does not support cascading. As explicitly stated in the datasheet, "The CEO feature is not available on the AT17LV65 device," and Figure 2-4 notes that CEO is absent on AT17LV65/128/256 devices. Cascading requires the CEO output to drive the CE input of the next device in chain - a capability reserved for AT17LV512 and higher-density variants. Therefore, AT17LV65-10NI is strictly limited to single-device configuration applications.
What is the significance of the "-10NI" suffix in AT17LV65-10NI?
The "-10NI" suffix denotes three key specifications: "-10" indicates a 10 MHz maximum clock frequency rating; "N" specifies the 8-lead SOIC (8S1) package; and "I" designates Industrial temperature grade (–40°C to +85°C). This distinguishes AT17LV65-10NI from commercial-grade variants like AT17LV65-10NC and confirms its suitability for demanding environments where thermal stability and long-term data retention are essential - critical attributes for the AT17LV65-10NI's target applications.
Can the AT17LV65-10NI be used with both 3.3V and 5V FPGAs?
Yes, the AT17LV65-10NI supports dual-voltage operation: 3.3V ±10% and 5.0V ±5% (Commercial) or ±10% (Industrial). Its VIH/VIL thresholds (2.0V min high, 0.8V max low) and output drive strength (VOH ≥2.4V at 3.3V, ≥3.7V at 5V) ensure interoperability with both 3.3V and 5V FPGA I/O standards without level shifters. This flexibility allows the AT17LV65-10NI to serve as a universal configuration memory across mixed-voltage FPGA platforms, including legacy Xilinx XC3000 and newer XC4000 families.
How is in-system programming (ISP) performed on the AT17LV65-10NI?
In-system programming of the AT17LV65-10NI is enabled by pulling the SER_EN pin Low, which activates its two-wire serial programming interface. Programming is performed at the same VCC supply voltage (3.3V or 5V) - no external high-voltage source is needed, as internal charge pumps generate required programming voltages. Industry-standard programmers (e.g., Atmel ATDH2225 ISP Cable) or compatible third-party tools can be used. During normal FPGA operation, SER_EN must be tied to VCC; misconfiguring SER_EN causes boot failure, so correct handling is essential for reliable AT17LV65-10NI deployment.
