Product details
Overview
AT17LV65-10JI from Atmel (now Microchip) is a 65,536 × 1-bit serial EEPROM FPGA configuration memory designed for industrial-temperature (-40°C to +85°C) applications. It supports both 3.3V and 5.0V operation, features in-system programmability via two-wire bus, and provides simple master-serial interface compatibility with Xilinx XC3000/XC4000, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
For engineers reviewing the AT17LV65-10JI datasheet, AT17LV65-10JI pinout, AT17LV65-10JI application, or AT17LV65-10JI equivalent, key selection considerations include its 20-lead PLCC industrial-grade package, programmable reset polarity, cascading limitations (no CEO pin), low-power standby mode (<100 µA at 3.3V), and EEPROM endurance of 100,000 write cycles with 90-year data retention at 85°C.
Technical Context
The AT17LV65-10JI operates in FPGA master-serial configuration mode, where the FPGA's CCLK drives the device's CLK input and DIN receives DATA output. Its RESET/OE pin serves dual function-active-Low reset and active-High output enable-with polarity programmable via EEPROM bytes.
It lacks the CEO (Chip Enable Output) pin, meaning it cannot support daisy-chain cascading with other AT17LV devices. Programming occurs in two-wire serial mode when SER_EN is pulled Low, while SER_EN must be tied to VCC during normal FPGA configuration loading.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DATA | Three-state bidirectional I/O; open-collector during programming, drives FPGA DIN during configuration |
| 2 | CLK | Input clock synchronized to FPGA CCLK; increments internal address counter on rising edge |
| 3 | RESET/OE | Programmable dual-function pin: active-Low reset (resets address counter) and active-High output enable |
| 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, 19 | NC | No-connect pins; electrically isolated and must remain unconnected per design |
| 7 | GND | Ground reference; requires 0.2 µF decoupling capacitor between VCC and GND |
| 8 | SER_EN | Serial enable input; must be tied to VCC for FPGA loading; pulled Low to enter two-wire ISP mode |
| 11 | VCC | Power supply input; accepts 3.3V ±10% or 5.0V ±10% (industrial); not internally regulated |
| 14 | CEO | Not available on AT17LV65-10JI; omitted from this variant - prevents cascading with other AT17LV devices |
| 17–18, 20 | NC | No-connect pins; no internal connection; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT17LV128-10JI | 128-Kbit capacity (2× density); identical 20-lead PLCC package, pinout, and AC/DC specs; includes same industrial temp and voltage support | Supports larger FPGA bitstreams (e.g., XC4010E, FLEX 10KA); no change required for board layout or FPGA interface logic | Select when future FPGA upgrades demand higher configuration memory - same footprint and timing, zero redesign effort |
| Xilinx XC18V02 | 2-Mbit serial PROM; 20-lead SOIC package (not PLCC); different pinout (no SER_EN, CEO present); requires PCB layout change | Enables cascading and supports Virtex-II/Virtex-E families; higher density but incompatible pin mapping and programming protocol | Choose only if migrating to Xilinx-only platforms with larger FPGAs and willingness to modify PCB and firmware |
Compared with AT17LV128-10JI and XC18V02, the AT17LV65-10JI offers optimal balance of industrial reliability, PLCC socket compatibility, and minimal system integration overhead for mid-size SRAM FPGAs - avoiding over-provisioning memory or committing to vendor-specific toolchains.

FAQ
What is the maximum clock frequency supported by the AT17LV65-10JI during FPGA configuration?
The AT17LV65-10JI supports a maximum clock frequency of 10 MHz under industrial conditions (3.3V ±10%, -40°C to +85°C). This timing is validated per AC characteristics Table 17, ensuring reliable data delivery to FPGAs such as Xilinx XC4000 or Altera FLEX 10K without setup/hold violations. The AT17LV65-10JI achieves this using internal CMOS EEPROM architecture optimized for synchronous serial readout.
Does the AT17LV65-10JI support cascading with other AT17LV devices for expanded configuration memory?
No, the AT17LV65-10JI does not support cascading because it lacks the CEO (Chip Enable Output) pin - explicitly noted in the datasheet Figures 2-4 through 2-7 and Section 7. This omission prevents daisy-chaining with other AT17LV series devices. For cascaded configurations, engineers must select AT17LV512-10JI or higher-density variants that include the CEO pin and validated timing (e.g., TOCK ≤ 60 ns).
What package type and footprint does the AT17LV65-10JI use, and is it socket-compatible?
The AT17LV65-10JI uses a 20-lead Plastic Leaded Chip Carrier (PLCC) package per JEDEC MS-018, Variation AA, with 1.27 mm lead pitch and 9.78 mm × 9.78 mm body. It is fully socket-compatible with standard 20-pin PLCC sockets used in industrial PCBs, enabling field replacement and prototyping flexibility without solder-level rework.
Can the AT17LV65-10JI be programmed in-system, and what interface is required?
Yes, the AT17LV65-10JI supports in-system programming (ISP) via a two-wire serial bus. This requires pulling the SER_EN pin Low while applying valid clock and data signals on CLK and DATA pins. Programming occurs at the same VCC supply voltage (3.3V or 5.0V) - no external high-voltage generator is needed, as internal charge pumps handle programming voltages.
What is the data retention and endurance specification for the AT17LV65-10JI at industrial temperature?
The AT17LV65-10JI guarantees 90 years of data retention at 85°C and 100,000 write/erase cycles under industrial operating conditions (-40°C to +85°C). These values are measured per JEDEC standards and reflect the device's EEPROM process technology - making it suitable for applications where FPGA configuration must remain intact over decades without maintenance or refresh.
