BR25H512F-5ACE2 詳細描述
Product Overview
The Rohm Semiconductor BR25H512F-5ACE2 is a non-volatile EEPROM memory IC with 512Kbit density and 64K x 8 organization. It communicates through an SPI interface at up to 20 MHz, with a 20 ns access time and a 3.5 ms word/page write cycle. The device operates from a 1.7 V to 5.5 V supply and is specified for an ambient temperature range of -40°C to 125°C. It uses an 8-SOP surface-mount package, 8-SOIC 0.173 in / 4.40 mm width, and carries an AEC-Q100 automotive grade.
Key Features
- 512Kbit non-volatile EEPROM memory organized as 64K x 8 for byte-oriented data storage.
- SPI serial interface supports clock operation up to 20 MHz.
- 20 ns access time and 3.5 ms word/page write cycle time.
- 1.7 V to 5.5 V supply voltage range.
- Operating temperature range of -40°C to 125°C (TA).
- AEC-Q100 automotive grade.
- Surface-mount 8-SOP package with 8-SOIC 0.173 in / 4.40 mm width.
Applications
- Automotive electronic control units requiring non-volatile storage of calibration, configuration, or diagnostic data.
- Embedded systems using an SPI host to store persistent device settings or lookup tables.
- Equipment operating across wide ambient temperature ranges where surface-mount EEPROM storage is needed.
Design & Procurement Notes
Designers should verify that the host controller supports SPI signaling, the selected clock frequency, and the 3.5 ms write cycle when planning page or word updates. The 1.7 V to 5.5 V supply range should be checked against the system power rail and I/O voltage levels. The 8-SOP / 8-SOIC surface-mount package should be checked against the board footprint and assembly layout. The -40°C to 125°C ambient range and AEC-Q100 automotive grade are relevant for automotive or extended-temperature embedded designs, and the 64K x 8 organization should be mapped to the required byte-addressable data capacity.
