BR25H512FVM-5ACTR

Product Overview

The Rohm Semiconductor BR25H512FVM-5ACTR is a non-volatile EEPROM memory IC with a 512Kbit capacity organized as 64K x 8. It communicates over an SPI interface at clock frequencies up to 20 MHz and has a 20 ns access time. The device operates from a 1.7V to 5.5V supply and is specified for an ambient temperature range of -40°C to 125°C. It is supplied in an 8-MSOP surface-mount package.

Key Features

• 512Kbit non-volatile EEPROM memory organized as 64K x 8
• SPI serial interface with a 20 MHz clock frequency
• 20 ns access time
• 3.5ms word or page write cycle time
• 1.7V to 5.5V supply voltage range
• -40°C to 125°C (TA) operating temperature range
• 8-MSOP surface-mount package, 0.110 inch, 2.80mm width

Applications

• Embedded controllers that need non-volatile storage of settings, identifiers, or calibration values after power loss
• SPI-connected devices that store data blocks for system configuration or user parameters
• Space-constrained surface-mount assemblies requiring a 512Kbit EEPROM in an 8-MSOP footprint

Design & Procurement Notes

Designers should account for the 3.5ms write cycle time when scheduling EEPROM updates and verify that the host SPI interface timing is compatible with the 20 MHz clock frequency and 20 ns access time. The 1.7V to 5.5V supply range and -40°C to 125°C (TA) operating range support wide-voltage and wide-temperature board layouts. When specifying the device for a bill of materials, use the exact part number and 8-MSOP surface-mount package to ensure the correct footprint and mounting style.
