BU9832GUL-W is a serial EEPROM of SPI BUS interface method. It features high-speed clock action, wait function, programmable read-only memory area, single power source action suitable for battery use, page write mode, and more.
The BU9832GUL-W is a high‑reliability serial EEPROM that uses an SPI bus interface. It offers a 1.8 V to 5.5 V single‑supply operation, making it suitable for battery‑powered designs. The device provides page‑write mode, automatic erase, and write‑protection features via HOLD, WP pin, and status‑register settings.
Technical specifications include an 8 Kbit capacity (1K × 8), VCSP50L2 (4‑pin) package, up to 5 MHz SCK frequency, and a data‑hold time of 40 years. Electrical characteristics show low standby current (0.1 µA typ.) and typical write current of 1.5 mA at 5 V. The EEPROM can endure up to 1 000 000 rewrite cycles and operates from –40 °C to +85 °C.
