AT17LV512-10JU 概要
A configuration EEPROM is a non-volatile serial memory that stores FPGA bitstream images and serially shifts them into the FPGA during power-up via a dedicated configuration interface. Within the broader taxonomy, configuration EEPROMs belong to memory ICs (specifically the EEPROM sub-family), then to programmable configuration PROMs, and ultimately to FPGA configuration devices. They sit at the boundary between the system MCU/flash storage and the FPGA, providing instant-on bitstream delivery without external flash controllers. The AT17LV family specifically targets FPGAs whose configuration interface uses the Altera (now Intel/Altera) pinout convention, making the AT17LV512-10JU a drop-in for that pinout.
Key features include 512 Kbit of user-programmable storage organized as 64K×8, in-system programmability (ISP) over a two-wire bus, three-state DATA output for bus sharing, and a RESET/OE + nCS control pair. The RESET/OE pin drives the address counter and tri-states the DATA pin when low, while nCS enables the device. Industrial temperature grade (-40°C to +85°C) supports factory-floor and outdoor deployments.
Architecturally, the device uses a simple counter-driven serial-read architecture: an internal oscillator clocks a 17-bit address counter that sequentially presents bitstream bytes on the DATA pin. The 10 MHz speed grade (the "-10" suffix) provides ~10 Mbit/s configuration throughput. The -JU suffix designates the 20-lead PLCC J-lead package, the standard surface-mount form for industrial FPGA configuration sockets.
Typical applications include industrial FPGA configuration storage on legacy 5V buses, factory automation controllers using Altera-pinout FPGAs, telecommunications line cards, and embedded computing modules.

Altera-Pinout FPGA Configuration Storage
The AT17LV512-10JU is purpose-built to store and serially deliver configuration bitstreams to Altera-pinout FPGAs on power-on, eliminating external flash controllers. Its 512 Kbit capacity matches mid-density Altera devices (Cyclone, APEX 20K, FLEX 10K), while the dual 3.3V/5.0V supply range (3.0V–3.6V / 4.5V–5.5V) lets the EEPROM sit directly on either rail without level shifting. The 10 MHz DCLK input yields full ~50 ms configuration time, and the RESET/OE + nCS control pair allows bus sharing with secondary PROMs. Placed adjacent to the FPGA with VCC decoupled by 0.1 µF ceramic, it provides deterministic cold-boot configuration.
おすすめ
Factory Automation Controllers
Industrial PLCs and machine controllers built around mid-density Altera FPGAs use the AT17LV512-10JU to deliver deterministic boot bitstreams in noisy factory-floor environments. Its industrial temperature grade (-40°C to +85°C) covers unconditioned cabinets, and the J-lead PLCC package withstands high-temperature reflow and vibration-prone enclosures better than SOIC alternatives. Concretely, the device's 4.5V–5.5V supply tolerance handles 5V industrial backplanes with substantial ripple, and the three-state bus architecture lets engineers parallel multiple PROMs for larger bitstreams without external buffers.
おすすめ
Telecommunications Line Cards
Legacy telecom line cards with Altera-pinout FPGAs continue to deploy the AT17LV512-10JU as the configuration memory because it provides instant-on bitstream delivery without MCU intervention. The dual-voltage operation lets the same EEPROM service both 3.3V and 5.0V line-card rails, simplifying multi-board variants. The 10 MHz configuration speed yields sub-100 ms boot for 512 Kbit images, acceptable for hitless-reinsert (HIR) and warm-swap line cards. The -JU's surface-mount J-lead package supports automated pick-and-place on high-mix telecom production lines.
おすすめ
Legacy Industrial Computing Modules
Embedded SBCs and IPC modules with long product lifecycles (10+ years in production) rely on the AT17LV512-10JU because it is a stable, long-running Altera configuration solution with guaranteed supply through Microchip's longevity program. Its 20-PLCC package is field-replaceable with standard rework tools, simplifying field service. Industrial temperature grade supports outdoor and cabinet-mounted installations, and the in-system programmable (ISP) two-wire interface enables field firmware updates without removing the EEPROM — a critical feature for service-deployed computing modules.
おすすめ
Automotive ECU Prototyping
Automotive ECU prototyping platforms based on Altera Cyclone FPGAs use the AT17LV512-10JU as a non-volatile configuration source during R&D and pre-production phases. Its industrial temperature rating covers under-hood-adjacent and cabin deployments, and the dual-voltage operation accommodates both 3.3V and 5V automotive rails. Engineers note the -JU J-lead package's robust solder joints survive engine-bay vibration better than fine-pitch QFN alternatives, and the in-system programmable two-wire interface allows rapid bitstream iteration during development without desoldering.
おすすめ
Medical Imaging Equipment
Stationary medical imaging systems (ultrasound, endoscopy controllers) with Altera FPGA-based beamforming or video pipelines use the AT17LV512-10JU as a redundant boot source to ensure deterministic startup after power interruption. The industrial temperature range covers regulated medical environments, and the three-state DATA output supports parallel configuration of multiple FPGAs on a single bus. The -JU PLCC package also simplifies agency-recertification cycles because the form factor is documented and stable — critical for FDA 510(k) and CE-MDR approval paths on long-lived medical platforms.

設計ノート
Do not confuse the AT17LV512 pinout with the older AT17LV65/128/256 pinout. Per the Atmel/Microchip AT17LV datasheet (Atmel-2322), the AT17LV65/128/256 are NOT pin-for-pin compatible with the AT17LV512/010/002/040 family. Substituting an AT17LV256 onto an AT17LV512 footprint will permanently damage the device and the FPGA configuration logic. Always verify the datasheet pinout before PCB rework. Also note the AT17LV65 and AT17LV128 are NRND (Not Recommended for New Designs).
Decouple VCC (pin 1) with a 0.1 µF X7R ceramic capacitor placed within 3 mm of the pin. The AT17LV512 draws modest supply current during configuration (typically <30 mA) but the dual-voltage mode (3.3V or 5V) requires the capacitor to be rated for the higher of the two operating voltages. For noisy industrial supplies, add a 10 µF bulk capacitor on the same rail as additional low-frequency decoupling. The RESET/OE (pin 4) and nCS (pin 3) lines should be pulled to VCC through 10 kΩ resistors to prevent spurious configuration triggers during power-up ramp.
Place the AT17LV512-10JU within 25 mm of the FPGA's DCLK/nCS/RESET/DATA pins to minimize trace capacitance and ensure clean configuration signaling. The 20-PLCC J-lead package has relatively large lead inductance compared to fine-pitch QFNs, so keep the DATA output trace short and avoid running it parallel to switching power converter traces. The J-lead package is rated for ~1.6 mm standoff from the PCB, which provides adequate creepage for most 5V industrial designs. For high-vibration deployments, add a small bead of RTV silicone under the package for additional mechanical stability.
The AT17LV512 uses an open-drain-style three-state DATA output. When multiple PROMs share a configuration bus, ensure that only one PROM's DATA output is enabled at any time by managing the nCS logic correctly. Per the AT17LV datasheet, driving RESET/OE low tri-states the DATA pin and resets the internal address counter, which is the standard mechanism for cascading multiple PROMs to configure larger FPGAs. Add a weak (10–100 kΩ) pull-up on the DATA line to define the idle-high state when all PROMs are tri-stated.
