BR25H640FVM-5ACTR

Product Overview

The BR25H640FVM-5ACTR from Rohm Semiconductor is a surface-mount non-volatile EEPROM memory IC with a 64Kbit capacity organized as 8K x 8. It communicates through an SPI interface at a 20 MHz clock frequency and operates from a 1.7V to 5.5V supply. The package is an 8-MSOP, also identified as 8-VSSOP, with a 2.80mm width, and the device is specified for operation over an ambient temperature range of -40°C to 125°C.

Key Features

• 64Kbit non-volatile EEPROM memory
• 8K x 8 memory organization
• SPI serial memory interface
• 20 MHz clock frequency
• 3.5ms write cycle time for word or page operations
• 1.7V to 5.5V supply voltage range
• -40°C to 125°C operating temperature range
• Surface-mount 8-MSOP package

Applications

• embedded systems requiring non-volatile parameter storage
• consumer electronic devices that retain configuration data through power cycles
• industrial control modules using SPI-connected memory for calibration or identification data
• board designs where an 8-MSOP memory device can be placed near a microcontroller

Design & Procurement Notes

Designers selecting the BR25H640FVM-5ACTR should confirm that the host controller supports SPI EEPROM access at the specified 20 MHz clock frequency and that the system power rail falls within the 1.7V to 5.5V supply range. The 8K x 8 organization defines the addressable byte structure, while the 3.5ms write cycle time for word or page operations should be considered in firmware timing and write sequencing. The 8-MSOP surface-mount package is appropriate for board layouts that place the memory device near the host controller, and the -40°C to 125°C ambient temperature range should be checked against the thermal environment of the final assembly.
