Product details
Overview
AT17LV65-10PC from Microchip Technology (formerly Atmel) is a 64-Kbit serial EEPROM FPGA configuration memory designed for master-serial mode loading of SRAM-based FPGAs. It supports dual-voltage operation (3.3V ±10% or 5.0V ±5%/±10%), delivers ≤50 µA standby current at 3.3V, features programmable reset polarity, and operates across -40°C to +85°C industrial temperature range. It interfaces directly with Xilinx XC3000/XC4000/Spartan, Altera FLEX/APEX, and Atmel AT40K/AT94K devices.
For engineers reviewing the AT17LV65-10PC datasheet, AT17LV65-10PC pinout, AT17LV65-10PC application, or AT17LV65-10PC equivalent, key selection criteria include its 8-lead PDIP/SOIC/LAP package compatibility, in-system programmability via two-wire bus, cascading limitations (no CEO pin), and verified interoperability with legacy FPGA configuration chains requiring 64-Kbit density and industrial-grade reliability.
Technical Context
The AT17LV65-10PC implements a serial-access architecture synchronized to an external FPGA-provided CCLK signal, enabling direct bitstream loading without host controller intervention. Its address counter auto-resets on power-up and is controlled by RESET/OE (active-low reset, active-high output enable) and CE (active-low chip enable) signals.
It uses a low-power CMOS EEPROM process with 100,000 write cycles endurance and 90-year data retention at 85°C. Programming occurs in two-wire serial mode when SER_EN is pulled low, while SER_EN tied to VCC enables standard FPGA master-serial operation - a critical distinction from ISP-only devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 65,536 × 1-bit (64 Kbit); sufficient for mid-complexity FPGA configuration bitstreams like Xilinx XC4000E or Altera FLEX6000 families. |
| Supply voltage | 3.3V ±10% or 5.0V ±5% (commercial) / ±10% (industrial); enables drop-in replacement in mixed-voltage legacy systems. |
| Standby current | <50 µA at 3.3V; reduces system-level quiescent power in always-on FPGA-based controllers. |
| Operating temperature | -40°C to +85°C (industrial grade); qualified for deployment in factory automation, motor drives, and outdoor telecom equipment. |
| Endurance | 100,000 write cycles; supports field firmware updates and reconfiguration during product lifecycle. |
| Data retention | 90 years at 85°C; ensures long-term configuration integrity in unattended embedded deployments. |
| Max clock frequency | 10 MHz (3.3V, industrial); sets upper bound on configuration speed for time-critical FPGA boot sequences. |
Pinout & Package
AT17LV65-10PC is available in 8-lead PDIP (8P3), 8-lead SOIC (8S1), and 8-lead LAP (8CN4) packages - all pin-compatible footprints. The device lacks CEO and READY pins, distinguishing it from higher-density AT17LV variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Bi-directional open-collector I/O | Drives FPGA DIN during configuration; tri-stated when RESET/OE high or CE high; used for two-wire programming when SER_EN low. |
| CLK | Input | Edge-triggered clock input synchronized to FPGA CCLK; increments internal address/bit counter for read or program operations. |
| RESET/OE | Input | Active-low reset (resets address counter) and active-high output enable (enables DATA driver); polarity programmable in EEPROM. |
| CE | Input | Active-low chip enable; disables counters and forces high-impedance DATA when high; does not affect two-wire programming mode. |
| WP | Input | Write protect (active-high); blocks writes to lowest memory block when asserted; present only on AT17LV65/128/256 variants. |
| SER_EN | Input | Serial enable; must be tied to VCC for FPGA master-serial operation; pulled low to enter two-wire ISP programming mode. |
| VCC | Power supply | Accepts 3.3V ±10% or 5.0V ±5%/±10%; requires 0.2 µF decoupling capacitor to GND per datasheet recommendation. |
| GND | Ground reference | Primary ground return path; essential for noise immunity in high-speed configuration clocking. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enables field firmware updates via two-wire bus without removing device from PCB - critical for remote maintenance of deployed FPGA systems. |
| Dual-voltage support | Eliminates need for level-shifting circuitry when interfacing with both 3.3V and 5V FPGA families, reducing BOM count and layout complexity. |
| Programmable reset polarity | Allows alignment with FPGA-specific reset timing requirements (e.g., active-low vs. active-high) without hardware modification. |
| Low-power standby mode | Draws <50 µA at 3.3V when CE is high, supporting energy-sensitive applications such as battery-backed industrial controllers. |
| Emulation of AT24CXXX EEPROMs | Permits reuse of existing serial EEPROM programming infrastructure and software drivers in FPGA configuration workflows. |

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, 3.3V-only, no 5V support; includes CEO pin for daisy-chaining; different pinout (20-pin PLCC). | Supports larger FPGAs (e.g., Virtex-E) requiring >64-Kbit configuration; unsuitable for space-constrained 8-pin layouts. | Select when higher density and cascading capability are required; not a pin-compatible replacement for AT17LV65-10PC. |
| Microchip AT17LV128-10PC | 128-Kbit density, identical 8-lead PDIP/SOIC/LAP packages, same pinout and electrical specs; adds no new functionality beyond capacity. | Direct upgrade path for FPGA designs needing expanded bitstream storage without layout changes. | Choose if future FPGA upgrades demand more configuration memory while retaining mechanical and electrical compatibility. |
Compared with XC18V02 and AT17LV128-10PC, the AT17LV65-10PC offers optimal balance of industrial temperature support, dual-voltage operation, and compact 8-pin packaging - making it ideal for cost-sensitive, space-constrained FPGA configurations where 64-Kbit capacity suffices and cascading is unnecessary.

FAQ
What is the primary function of the AT17LV65-10PC in an FPGA system?
The AT17LV65-10PC serves as a dedicated serial configuration memory that stores and delivers the bitstream to SRAM-based FPGAs during power-up or reset. It operates in master-serial mode, receiving clocking from the FPGA's CCLK pin and driving the FPGA's DIN pin directly. The AT17LV65-10PC eliminates the need for external microcontrollers in configuration sequencing, enabling autonomous FPGA initialization.
Does the AT17LV65-10PC support in-system programming (ISP)?
Yes, the AT17LV65-10PC supports in-system programming via a two-wire serial interface when the SER_EN pin is pulled low. This allows field updates of the FPGA configuration bitstream without removing the device from the PCB. During normal FPGA operation, SER_EN must be tied to VCC to enable master-serial mode - a key design constraint confirmed in the official datasheet.
Can the AT17LV65-10PC be used in cascaded configurations with other AT17LV devices?
No, the AT17LV65-10PC does not support cascading because it lacks the CEO (Chip Enable Output) pin, which is required to daisy-chain multiple configuration EEPROMs. This limitation is explicitly documented: "The CEO feature is not available on the AT17LV65 device." For cascaded applications, higher-density variants like AT17LV512 or AT17LV010 must be selected instead.
What package options are available for the AT17LV65-10PC, and are they interchangeable?
The AT17LV65-10PC is offered in 8-lead PDIP (8P3), 8-lead SOIC (8S1), and 8-lead LAP (8CN4) packages - all with identical pinouts and fully interchangeable footprints. The LAP package measures 6 mm × 6 mm × 1 mm and is pin-compatible with standard 8-lead SOIC, enabling migration to smaller form factors without PCB redesign.
How does the programmable reset polarity feature work in the AT17LV65-10PC?
The AT17LV65-10PC allows users to configure the RESET/OE pin's logic polarity via EEPROM programming - selecting between active-low reset with active-high output enable (default) or alternate polarity. This is implemented by programming four specific EEPROM bytes and is supported by industry-standard programmers like the ATDH2200E. The setting persists across power cycles and ensures compatibility with diverse FPGA reset architectures.
