Product details
Overview
AT17LV65-10PI from Atmel is a 64-Kbit (65,536 × 1-bit) serial EEPROM FPGA configuration memory designed for industrial-temperature (-40°C to +85°C) operation at 3.3V or 5.0V. It supports Master Serial mode loading of SRAM-based FPGAs including Xilinx XC3000/XC4000 and Altera FLEX devices, features programmable reset polarity, and delivers ≤100 µA standby current at 3.3V. Its primary role is nonvolatile storage and sequential delivery of FPGA bitstreams during power-up.
For engineers reviewing the AT17LV65-10PI datasheet, AT17LV65-10PI pinout, AT17LV65-10PI application, or AT17LV65-10PI equivalent, key selection criteria include industrial-grade temperature support, dual-voltage compatibility (3.3V/5V), in-system programmability via two-wire bus, cascading limitations (no CEO pin), and 8-lead PDIP package footprint with verified timing parameters for FPGA clock rates up to 10 MHz.
Technical Context
The AT17LV65-10PI operates in Master Serial mode, interfacing directly with FPGA CCLK and DIN pins using a simple synchronous serial protocol. Its internal address counter advances on CLK edges, with RESET/OE controlling counter reset and DATA output enable/disable. SER_EN must be tied high during FPGA configuration and pulled low only for ISP programming.
Unlike higher-density AT17LV variants, the AT17LV65-10PI lacks CEO, READY, WP1, WP2, and A2 pins-limiting it to single-device configurations without daisy-chaining or advanced write protection. Its pinout is shared across AT17LV65/128/256 family members but incompatible with AT17LV512+ devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 65,536 × 1-bit (64 Kbit) - stores full configuration bitstream for mid-complexity SRAM FPGAs like Xilinx XC4005 or Altera EPF10K10. |
| Supply voltage | 3.3V ±10% or 5.0V ±10% - supports legacy 5V and modern 3.3V FPGA systems without level-shifting. |
| Operating temperature | -40°C to +85°C - qualified for industrial environments including factory automation and outdoor telecom equipment. |
| Standby current | ≤100 µA at 3.3V - enables low-power hold states during FPGA reconfiguration or system sleep modes. |
| Max clock frequency | 10 MHz (3.3V, industrial) - sets upper limit on FPGA configuration speed; matches typical XC4000-series CCLK requirements. |
| Endurance | 100,000 write cycles - sufficient for field firmware updates and design iteration during prototyping and production validation. |
| Data retention | 90 years at 85°C - ensures long-term reliability in unattended embedded deployments without battery backup. |
Pinout & Package
AT17LV65-10PI is supplied in an 8-lead plastic dual-inline package (PDIP), 0.300" wide, with JEDEC-standard pin spacing and thermal characteristics θJA = 107°C/W (industrial).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DATA) | Bi-directional I/O | Open-collector output during FPGA read; input during ISP programming - requires external pull-up for proper logic levels. |
| 2 (CLK) | Input | Drives internal address/bit counter on rising edge - synchronized to FPGA CCLK for deterministic bitstream delivery. |
| 3 (RESET/OE) | Input | Active-low reset + active-high output enable - programmable polarity allows matching FPGA reset architecture (e.g., Xilinx vs. Altera defaults). |
| 4 (CE) | Input | Active-low chip enable - disables counter and tri-states DATA when high, entering low-power standby mode. |
| 5 (GND) | Power reference | Ground return path - requires 0.2 µF decoupling capacitor near VCC pin per datasheet recommendation. |
| 6 (CEO) | Output | Not available on AT17LV65-10PI - omission prevents cascaded multi-device configurations. |
| 7 (SER_EN) | Input | Serial enable - must be tied to VCC during FPGA operation; pulled low only to enter two-wire ISP mode. |
| 8 (VCC) | Power supply | 3.3V or 5.0V main supply - tolerates ±10% variation; supports mixed-voltage board designs. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Two-wire serial interface enables field firmware updates without socket removal or dedicated programmers. |
| Programmable reset polarity | Four EEPROM bytes configure RESET/OE as active-low reset or active-high output enable - eliminates need for external inverters. |
| Low-power standby mode | CE-driven state draws ≤100 µA at 3.3V - reduces system-level quiescent power in always-on FPGA applications. |
| Industrial temperature rating | Validated operation from -40°C to +85°C - suitable for deployment in harsh environments without derating. |
| Emulation of AT24CXXX EEPROMs | Compatible with standard I²C-compatible programmers and test infrastructure - simplifies integration into existing manufacturing flows. |

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 capacity; supports cascading via CEO; requires 3.3V only; no 5V operation. | Enables larger FPGA configurations and daisy-chain topologies; unsuitable for 5V legacy systems. | Select when upgrading to higher-density FPGAs or requiring multi-device chaining; verify voltage compatibility. |
| Microchip 25LC640 | 64-Kbit SPI EEPROM; no built-in FPGA timing control; no RESET/OE or SER_EN pins; requires external controller for configuration sequencing. | Needs MCU or CPLD to manage bitstream delivery; not plug-and-play with FPGA Master Serial mode. | Select only if adding microcontroller-based configuration management; avoid for direct FPGA boot. |
Compared with XC18V02 and 25LC640, the AT17LV65-10PI uniquely combines industrial temperature rating, dual-voltage support, and native Master Serial interface - making it optimal for drop-in replacement in legacy 5V/3.3V FPGA systems without redesign.

FAQ
What is the maximum clock frequency supported by the AT17LV65-10PI during FPGA configuration?
The AT17LV65-10PI supports a maximum clock frequency of 10 MHz under industrial conditions (3.3V ±10%, -40°C to +85°C). This timing aligns with the CCLK requirements of Xilinx XC4000 and Altera FLEX10K FPGAs. Exceeding this limit may cause bitstream corruption due to insufficient setup/hold margins on DATA output.
Does the AT17LV65-10PI support cascading with other configuration EEPROMs?
No, the AT17LV65-10PI does not support cascading. The CEO (Chip Enable Output) pin is explicitly omitted from this device, as confirmed in the datasheet notes for Figures 2-4 through 2-8 and Section 7. Cascading requires CEO functionality to chain multiple devices, which is only available on AT17LV512 and higher-density variants.
Can the AT17LV65-10PI be used with both 3.3V and 5.0V FPGA systems?
Yes, the AT17LV65-10PI is fully compatible with both 3.3V and 5.0V operating voltages, supporting ±10% tolerance in each case. Its I/O thresholds (VIH ≥2.0V, VIL ≤0.8V) ensure interoperability with mixed-voltage FPGA families, eliminating level-shifters in transitional designs.
How is the reset polarity programmed on the AT17LV65-10PI?
The reset polarity of the AT17LV65-10PI is programmed by writing to four specific EEPROM bytes using an industry-standard programmer or Atmel's ATDH2200E kit. This allows configuration of the RESET/OE pin as either active-low reset or active-high output enable - matching the default behavior of target FPGAs such as Xilinx or Altera devices.
What package types are available for the AT17LV65-10PI, and which one does the "-PI" suffix indicate?
The "-PI" suffix in AT17LV65-10PI specifies the 8-lead plastic dual-inline package (PDIP) with industrial temperature rating. Other package options for the AT17LV65 include 8-lead SOIC ("-NI") and 20-lead PLCC ("-JI"), but the "-PI" variant is exclusively PDIP, offering through-hole mounting and proven reliability in vibration-prone industrial assemblies.
