BR24L02FJ-WE2

Product Overview

The BR24L02FJ-WE2 from Rohm Semiconductor is a non-volatile EEPROM memory IC with a 2Kbit capacity organized as 256 x 8 bits. It communicates through an I2C interface at a clock frequency of 400 kHz and operates from a supply voltage range of 1.8V to 5.5V. The device is supplied in an 8-SOP-J surface-mount package, corresponding to an 8-SOIC case with 0.154 inch (3.90mm) width. Its specified operating temperature range is -40°C to 85°C (TA), and the write cycle time for word or page operations is 5ms.

Key Features

• 2Kbit non-volatile EEPROM memory organized as 256 x 8 bits
• I2C serial interface with 400 kHz clock frequency
• Supply voltage range of 1.8V to 5.5V
• Surface-mount 8-SOP-J package with 8-SOIC 0.154 inch (3.90mm) width
• Operating temperature range of -40°C to 85°C (TA)
• 5ms write cycle time for word or page operations

Applications

• Embedded systems that retain small configuration or calibration data after power removal
• I2C-connected peripheral modules requiring byte-addressable non-volatile memory
• Space-constrained electronic assemblies using a compact 8-SOP-J surface-mount package

Design & Procurement Notes

For system planning, confirm that the host controller supports I2C communication at 400 kHz and that the stored data set fits within 256 x 8 bits. The 5ms word or page write cycle time should be considered in firmware write sequencing, bus timing, and power-down behavior. The 1.8V to 5.5V supply range should be matched to the system supply voltage, while the -40°C to 85°C operating range defines the ambient temperature envelope. Board layout should account for the 8-SOP-J surface-mount package and the 8-SOIC 0.154 inch (3.90mm) width footprint.
