BRCH064GWZ-3E2

Product Overview

The Rohm Semiconductor BRCH064GWZ-3E2 is a 64 Kbit nonvolatile EEPROM memory IC organized as 8K x 8 and accessed through an I2C serial interface. The device operates from 1.6 V to 5.5 V and supports a 400 kHz clock frequency, with a 5 ms write cycle time for word and page operations. It is supplied in a surface-mount 6-XFBGA, CSPBGA package, identified as UCSP30L1A, and is rated for operation from -40°C to 85°C (TA). This memory component is intended for embedded designs requiring small-capacity serial data retention without continuous power.

• Operating temperature range of -40°C to 85°C (TA)
• Surface-mount 6-XFBGA, CSPBGA package supplied as UCSP30L1A
• Rohm Semiconductor part number BRCH064GWZ-3E2

Applications

• Storing device configuration settings and calibration values in embedded systems
• Retaining serial numbers, asset identifiers, or small parameter tables
• Providing nonvolatile memory for low-voltage electronics

Design & Procurement Notes

When using the BRCH064GWZ-3E2 in an embedded design, allocate PCB area for the surface-mount 6-XFBGA, CSPBGA package and confirm the UCSP30L1A footprint with the manufacturer documentation. The 1.6 V to 5.5 V supply voltage range allows connection to systems within that range, while the I2C interface and 400 kHz clock frequency require bus timing and interface compatibility review. The 5 ms word/page write cycle time should be considered in firmware write routines. The -40°C to 85°C (TA) operating range helps identify thermal margins, and the 64 Kbit 8K x 8 EEPROM organization is suitable for small configuration, calibration, or identifier data rather than large data buffers.
