Product Overview

The ROHM BR24G32NUX-3TTR is a 32Kbit (4,096 x 8) serial EEPROM with an I²C interface, offering an extremely wide operating voltage range of 1.6V to 5.5V. This makes it ideal for systems that transition between low‑power standby and full operation, including 1.8V, 2.5V, 3.3V, and 5V logic. The device supports standard (100kHz), fast (400kHz), and fast‑plus (1MHz) I²C modes, providing flexible and high‑speed data transfer for configuration storage, parameter logging, and device calibration.

The BR24G32NUX features a page write capability of up to 32 bytes, with a maximum write cycle time of 5 ms. Packaged in an ultra‑compact VSON008X2030 (2x3mm) leadless package (NUX‑3TTR suffix), it occupies minimal board space while delivering high reliability. The device operates over the industrial temperature range of -40°C to +85°C and offers 1,000,000 write cycles and 100‑year data retention, making it suitable for industrial control, wearable devices, medical equipment, and IoT sensors.

⚡ I²C Performance & Power Efficiency

1MHz Fast‑Plus Mode

Read throughput: 128 kbyte/s
Write throughput: up to 6.4 kbyte/s (page write)

Ultra‑Low Standby

0.5µA typical standby current extends battery life in always‑on systems.

Self‑Timed Write Cycle

5ms max internally controlled, no external timing components needed.

The BR24G32NUX includes a write enable latch (WEL) that prevents accidental writes after power‑up. A write disable command resets the latch, adding an extra layer of security against unintended modifications.

🧠 Memory Organization & Addressing

The 32Kbit memory is organized as 4,096 x 8 (4KB). The device uses a two‑byte address word (low and high) for random reads/writes. Page write allows up to 32 consecutive bytes to be written with a single internal write cycle, significantly improving throughput for block updates.

🔌 Hardware Address Pins (A0, A1, A2)

These pins allow up to eight devices to share the same I²C bus (total bus capacity 256Kbit). The fixed I²C slave address is 1010 (binary) followed by the three address bits set by A2/A1/A0, then the read/write bit.
