Product details
Overview
AT17LV65-10JC from Atmel is a 64-Kbit (65,536 × 1-bit) serial EEPROM FPGA configuration memory designed for master-serial mode loading of SRAM-based FPGAs. It operates at 3.3V or 5.0V, supports in-system programming via two-wire bus, features programmable reset polarity, and delivers ≤50 µA standby current at 3.3V. Used in industrial embedded systems requiring reliable, low-power configuration storage.
For engineers reviewing the AT17LV65-10JC datasheet, AT17LV65-10JC pinout, AT17LV65-10JC application, or AT17LV65-10JC equivalent, key selection criteria include its 20-lead PLCC package, 10 MHz max clock frequency at 3.3V, cascading limitations (no CEO pin), industrial temperature range (–40°C to +85°C), and compatibility with Xilinx XC3000/XC4000, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
Technical Context
The AT17LV65-10JC implements a serial-access configuration memory architecture with synchronous read-out controlled by FPGA-generated CLK and CE signals. Its internal address counter auto-resets on power-up and on active-low RESET/OE assertion, enabling deterministic initialization without external logic.
It uses a CMOS EEPROM process with 100,000 write cycles endurance and 90-year data retention at 85°C. The device lacks CEO output and READY pin-distinguishing it from higher-density AT17LV variants-and relies solely on CE and RESET/OE for tri-state control and counter management during daisy-chain operation.
Key Specifications

| 2 | CLK | Input clock synchronizing address increment and bit output; driven by FPGA CCLK |
| 3 | RESET/OE | Combined active-low reset and active-high output enable; resets address counter and controls DATA driver state |
| 4 | CE | Active-low chip enable; disables address counter and forces DATA into high-impedance when high |
| 5–6, 9–10, 12–13, 15–16, 18–19 | NC | No-connect pins - unused in AT17LV65; must remain unconnected per design |
| 7 | SER_EN | Serial enable input; must be tied to VCC for FPGA loading, pulled low only during ISP programming |
| 8 | GND | Ground reference; requires 0.2 µF decoupling capacitor to VCC |
| 11 | VCC | Power supply input; accepts 3.3V or 5.0V with specified tolerances |
| 14 | CEO | Not available on AT17LV65 - omitted from this variant; prevents cascading with other AT17LV devices |
| 17 | SER_EN | Duplicate SER_EN pin (pin 7); electrically identical, used for layout routing flexibility |
| 20 | GND | Second ground connection - improves noise immunity and thermal dissipation |

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, 20-lead PLCC, no SER_EN pin, requires external programmer; not ISP-capable | Supports larger FPGAs but lacks in-system update capability | Select when higher density is required and field updates are unnecessary |
| Microchip 25LC640A-I/P | 64-Kbit SPI EEPROM, 8-lead PDIP/SOIC, 5V-only, no FPGA-specific timing or RESET/OE dual function | Requires FPGA-side logic to emulate configuration protocol; no native master-serial support | Select only for custom configuration controllers where standard SPI suffices |

FAQ
What is the maximum clock frequency supported by the AT17LV65-10JC at 3.3V?
The AT17LV65-10JC supports a maximum clock frequency of 10 MHz at 3.3V under industrial conditions (–40°C to +85°C). This value is specified in the AC Characteristics table (Section 17) and defines the upper limit for reliable configuration data transfer speed when interfacing with FPGAs such as Xilinx XC4000 or Altera FLEX devices. Exceeding this frequency may result in timing violations and incomplete bitstream loading.
Does the AT17LV65-10JC support cascading with other AT17LV devices?
No, the AT17LV65-10JC does not support cascading because it lacks the CEO (Chip Enable Output) pin, which is explicitly noted as "not available on the AT17LV65 device" in the datasheet (Section 4.9 and Figure 2-4 notes). Cascading requires CEO to drive the CE input of the next device in the chain, so AT17LV65-10JC must be used as a standalone configuration memory. Higher-density variants like AT17LV512-10JC include CEO and support daisy-chaining.
What package type is used for the AT17LV65-10JC?
The AT17LV65-10JC uses a 20-lead Plastic Leaded Chip Carrier (PLCC) package, designated as 20J in Atmel's ordering nomenclature. This JEDEC MS-018 compliant package has a 9.78 mm × 9.78 mm body, 1.27 mm lead pitch, and J-shaped leads. It is distinct from the 8-lead LAP/SOIC/PDIP packages used for lower-pin-count variants and provides robust thermal and mechanical performance for industrial applications.
Can the AT17LV65-10JC be programmed in-system (ISP)?
Yes, the AT17LV65-10JC supports in-system programming via its two-wire serial interface. This is enabled by pulling the SER_EN pin low, which activates the ISP mode. Programming occurs at the same VCC supply voltage (3.3V or 5.0V) without requiring external high-voltage sources-the device generates necessary programming voltages internally. Industry-standard programmers and Atmel's ATDH2225 ISP Cable are compatible.
What is the data retention specification for the AT17LV65-10JC at industrial temperature?
The AT17LV65-10JC guarantees 90 years of data retention at 85°C for industrial-grade operation. This specification is explicitly stated in the Features section and confirmed in Section 1, "Description." It reflects the EEPROM process reliability under worst-case thermal stress and ensures long-term bitstream integrity in applications such as factory automation controllers and outdoor telecom equipment where field replacement is impractical.
