BR24L32FJ-WE2

Product Overview

The BR24L32FJ-WE2 from Rohm Semiconductor is an 8-SOP-J surface-mount EEPROM memory IC for systems that require nonvolatile storage over an I2C interface. It provides 32 Kbit of memory organized as 4K x 8 and operates from 1.8 V to 5.5 V. The device supports a 400 kHz clock frequency and has a 5 ms write cycle time for word and page operations. Its operating temperature range is -40°C to 85°C (TA). This memory IC is suited to embedded designs that need to retain configuration or calibration data when power is removed.

Key Features

• 32 Kbit nonvolatile EEPROM memory with a 4K x 8 organization
• I2C serial interface with 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
• Surface-mount 8-SOP-J package, 8-SOIC case with 0.154 in (3.90 mm) width
• Operating temperature range of -40°C to 85°C (TA)

Applications

• Microcontroller-based devices that store configuration parameters and retain them after power cycling
• Systems that use a nonvolatile memory for calibration constants or identification data
• Embedded boards that require serial EEPROM access over an I2C bus

Design & Procurement Notes

When using this EEPROM, confirm that the host can operate the I2C bus at 400 kHz and that the data size fits the 4K x 8 organization. The 5 ms write cycle time should be considered in update routines for word and page writes. Layout should accommodate the 8-SOP-J surface-mount package, and the system supply should remain within 1.8 V to 5.5 V. Verify that the operating temperature range of -40°C to 85°C (TA) matches the intended environment.
