Product details
Overview
AT17LV65-10SI from Microchip Technology (formerly Atmel) is a 64-Kbit serial EEPROM FPGA configuration memory, supporting 3.3V and 5.0V operation, programmable reset polarity, in-system programming via two-wire bus, and low-power standby mode (<100 µA at 3.3V industrial). It interfaces directly with SRAM-based FPGAs including Xilinx XC3000/XC4000 and Altera FLEX® in Master Serial mode.
For engineers reviewing the AT17LV65-10SI datasheet, AT17LV65-10SI pinout, AT17LV65-10SI application, or AT17LV65-10SI equivalent, key selection criteria include its 8-lead SOIC package compatibility, 65,536 × 1-bit density, industrial temperature range (–40°C to +85°C), and absence of CEO pin for cascading-critical when designing single-FPGA systems requiring reliable, low-pin-count configuration storage.
Technical Context
The AT17LV65-10SI operates as a dedicated serial configuration memory for SRAM-based FPGAs, using a simple clocked read protocol where CLK increments an internal address counter and DATA outputs configuration bits synchronously. Its RESET/OE pin serves dual function-active-Low reset and active-High output enable-with programmable polarity stored in EEPROM.
It supports two operational modes: FPGA loading (SER_EN = High) and two-wire ISP programming (SER_EN = Low). In loading mode, CE and RESET/OE jointly control data output tri-state and counter reset; no CEO output is available, precluding daisy-chain configurations. Standby current is <100 µA at 3.3V/industrial conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 65,536 × 1-bit (64 Kbit) - sufficient for mid-complexity SRAM FPGAs like Xilinx XC4000E or Altera FLEX 10K series. |
| Supply voltage | 3.0–3.6 V or 4.5–5.5 V - dual-voltage support enables drop-in replacement across legacy 5V and modern 3.3V FPGA systems. |
| Operating temperature | –40°C to +85°C - qualified for industrial environments without derating. |
| Standby current | <100 µA at 3.3V - enables low-power hold during FPGA sleep or system suspend states. |
| Write endurance | 100,000 cycles - supports field reconfiguration and firmware updates over product lifetime. |
| Data retention | 90 years at 85°C - ensures configuration integrity over full industrial lifecycle without refresh. |
| Max clock frequency | 10 MHz (3.3V industrial) - matches typical FPGA CCLK timing budgets for reliable serial loading. |
Pinout & Package
AT17LV65-10SI is supplied in an 8-lead SOIC (8S1) package, 0.150" wide, with standard JEDEC SOIC footprint and 1.27 mm pitch. Pin 1 is marked by notch or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DATA | I/O (open-collector) | Bi-directional serial data line; drives FPGA DIN during configuration; pulled up externally. |
| 2 CLK | Input | Master clock input from FPGA CCLK; increments internal address counter on rising edge. |
| 3 RESET/OE | Input | Programmable polarity pin: active-Low reset / active-High output enable; resets counter and controls DATA driver. |
| 4 CE | Input | Chip enable (active-Low); enables counter and DATA output when LOW and RESET/OE is HIGH. |
| 5 GND | Power | Ground reference; requires 0.2 µF decoupling capacitor near VCC pin. |
| 6 SER_EN | Input | Serial enable (High = FPGA load mode; Low = two-wire ISP programming mode). |
| 7 VCC | Power | 3.3V ±10% or 5.0V ±10% supply; must be stable before releasing RESET/OE. |
| 8 CEO (A2) | Not connected | CEO function not implemented on AT17LV65; pin is NC (no connection) per datasheet Figure 2-2 and Note 3. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Two-wire serial interface (SER_EN = Low) enables field firmware updates without socket removal or UV erasure. |
| Programmable reset polarity | EEPROM-stored configuration allows RESET/OE logic polarity to match FPGA requirements (e.g., active-Low reset for Xilinx, active-High OE for Altera). |
| Low-power standby | CE = High disables counters and forces DATA into high-impedance state, drawing <100 µA - ideal for battery-backed or energy-sensitive systems. |
| Emulation of AT24CXXX | Compatible with industry-standard serial EEPROM programmers and protocols, simplifying integration into existing programming workflows. |
| Green packaging | RoHS-compliant, Pb/halide-free construction meets global environmental compliance requirements for industrial electronics. |

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 density, 8-pin SOIC, supports only 3.3V; no 5V operation; includes CEO for cascading. | Higher density suitable for larger FPGAs; lacks dual-voltage flexibility and industrial-grade 5V support. | Select when >64 Kbit is required and system operates exclusively at 3.3V with cascaded configuration needs. |
| Microchip AT17LV128-10SI | 128-Kbit density, identical pinout/package, same 3.3V/5V and industrial temp support; includes WP pin. | Direct upgrade path offering double memory capacity while maintaining PCB layout and firmware compatibility. | Choose when future FPGA bitstream growth is anticipated and board space/layout reuse is critical. |
Compared with XC18V02 and AT17LV128-10SI, the AT17LV65-10SI provides optimal balance of industrial temperature operation, dual-voltage compatibility, and minimal pin count for cost-sensitive, single-FPGA systems-without requiring CEO-driven daisy-chaining or over-provisioned memory.

FAQ
What is the memory organization of the AT17LV65-10SI?
The AT17LV65-10SI contains 65,536 × 1-bit (64 Kbit) of EEPROM memory organized as a linear serial array. It is not byte-addressable like standard I²C EEPROMs; instead, it streams configuration data sequentially upon clocking, starting from address 0x0000 and wrapping automatically after the final bit. This architecture is optimized for FPGA bitstream loading rather than random-access data storage.
Does the AT17LV65-10SI support cascading with other configuration EEPROMs?
No, the AT17LV65-10SI does not support cascading. As explicitly stated in the datasheet (Section 7 and Figure 2-4 note), the CEO (Chip Enable Output) feature is not available on the AT17LV65 device. Therefore, AT17LV65-10SI cannot drive the CE input of a subsequent configurator in a daisy chain. For cascaded configurations, higher-density variants such as AT17LV512-10SI must be used.
Can the AT17LV65-10SI operate at both 3.3V and 5.0V simultaneously?
No, the AT17LV65-10SI operates at either 3.3V (±10%) or 5.0V (±10% for industrial grade), but not both simultaneously. The VCC pin accepts one supply voltage only. DC and AC specifications are separately characterized for each voltage; mixing voltages risks violating absolute maximum ratings and invalidates timing parameters. Designers must select one operating voltage and ensure compatible FPGA I/O levels.
What is the purpose of the SER_EN pin on the AT17LV65-10SI?
The SER_EN pin on the AT17LV65-10SI selects operational mode: when held HIGH, the device operates in FPGA configuration mode (serial readout); when driven LOW, it enters two-wire in-system programming mode. For standard FPGA boot applications, SER_EN must be tied to VCC. Leaving it floating or improperly biased may cause unpredictable behavior during power-up or configuration.
Is the AT17LV65-10SI pin-compatible with other AT17LV variants in SOIC packages?
Yes, the AT17LV65-10SI is pin-compatible with AT17LV128-10SI and AT17LV256-10SI in the 8-lead SOIC (8S1) package. All three share identical pin assignments and electrical characteristics for pins 1–8. However, AT17LV512-10SI and higher-density variants use different pinouts and are not pin-compatible - they require PCB redesign even in the same package type.
