Description

AT17LV512-10JU is Atmel/Microchip’s low-voltage 512-kbit serial PROM (nonvolatile memory), typically used as a configuration or boot memory.
Key points:
- Capacity/organization: 512 Kbits, arranged as 64K × 8.
- Interface: Microwire/SPI-like serial interface with CS, CLK, DI, DO.
- Voltage: 2.7–3.6 V (low-voltage operation).
- Speed grade: -10 indicates up to 10 MHz serial clock.
- Package: 8-pin small-outline (SOP) package (package code JU).
- Use: Storing configuration data for FPGAs/PLDs, microcontrollers, boot data, etc.
- Nature: Nonvolatile memory; data retained without power; generally not intended for frequent in-system rewriting (PROM with fixed data).
For exact opcodes, timing, addressing, and write/erase behavior, refer to the datasheet.

Features

Key features of AT17LV512-10JU:
- 512 Kbit serial EEPROM (64K × 8)
- I2C two‑wire interface: standard/fast mode (100/400 kHz)
- Low‑voltage operation: VCC 1.65–3.6 V
- 3 address pins (A0–A2) + WP (write‑protect) pin
- Page write capability (32-byte pages) with automatic write cycle
- Supports random and sequential reads
- Endurance: up to about 1,000,000 write cycles; data retention ~40 years
- Low power with low active/standby currents
- Operating temperature: typically −40°C to +85°C (industrial)
- Package: 8‑pin (JU) package (e.g., SOIC/DIP variants)
Suitable for storage of small data blocks, configuration data, and device IDs in low‑voltage embedded systems.

Package

28-pin SOIC (small-outline) package.

Pinout

- Pin count: 8 pins (DIP-8/SOIC-8)
- Function: 512-kbit low-voltage SPI Serial EEPROM memory. Non-volatile data storage with SPI interface (CS, SCK, SI, SO) plus WP, HOLD, VCC, and GND.

Manufacturer

- Manufacturer: Atmel Corporation (now part of Microchip Technology after a 2016 acquisition).
- What kind of company: An American semiconductor company that designs and manufactures memory and microcontroller ICs for embedded systems (an IDM with its own fabrication).

Application

- External configuration memory for FPGAs/CPLDs (bitstreams)
- Boot/firmware memory for microcontrollers and embedded processors
- Low-voltage non-volatile storage for system parameters, calibration data, and LUTs
- Field-upgradable memory in consumer and industrial electronics
- General SPI-compatible/low-voltage non-volatile storage where compact, reliable config data is needed
