Description
AT17LV512-10JU is an Atmel (now Microchip) 512‑kbit low‑voltage SPI EEPROM. It stores data nonvolatily in a 64K × 8 organization and is intended for code/config data, boot ROMs, and small look‑ups.
Key points:
- Interface: SPI-compatible (CS, CLK, DI, DO) with optional WP and HOLD pins.
- Voltage: 2.7–3.6 V (LV family).
- Speed grade: -10 (up to about 10 MHz clock).
- Package: 8‑pin SOIC (suffix JU).
- Typical use: microcontroller/FPGA configuration data, firmware storage.
For exact timing, write/page sizes, endurance, and pinout, refer to the specific datasheet.
