BR24L04FVT-WE2

Product Overview

The Rohm Semiconductor BR24L04FVT-WE2 is a 4Kbit EEPROM memory IC with a 512 x 8 organization and an I2C serial interface. It operates from a 1.8 V to 5.5 V supply and supports a 400 kHz clock frequency, while the specified write cycle time for word and page operations is 5 ms. The device is housed in a surface-mount 8-TSSOP-B package with a 4.40 mm body width and is rated for an operating temperature range of -40°C to 85°C (TA). Its non-volatile memory format allows stored data to be retained without continuous power, making it appropriate for small-scale parameter and configuration storage in compact electronic assemblies.

Key Features

• 4Kbit EEPROM memory with a 512 x 8 organization.
• I2C serial interface supporting a 400 kHz clock frequency.
• 1.8 V to 5.5 V supply voltage range.
• 5 ms write cycle time for word and page operations.
• -40°C to 85°C (TA) operating temperature range.
• Surface-mount 8-TSSOP-B package, 0.173 in / 4.40 mm width.
• Non-volatile memory format for data retention without continuous power.

Applications

• Retention of configuration parameters in embedded control systems after power cycling.
• Storage of calibration constants and small lookup tables for measurement modules.
• Device identification and parameter storage in compact circuit assemblies.

Design & Procurement Notes

When selecting the device, verify that the host controller supports an I2C bus at 400 kHz and that the supply voltage remains within 1.8 V to 5.5 V. The 5 ms word and page write cycle should be included in firmware timing, especially for repeated updates. The 4Kbit capacity and 512 x 8 organization are suited to small parameter sets rather than large data buffers. The 8-TSSOP-B surface-mount package with 4.40 mm width affects land pattern and board density. The -40°C to 85°C (TA) operating range should be checked against the final assembly environment, and the non-volatile format should be evaluated against the required data retention behavior without continuous power.
