The BR9040-W is a serial EEPROM from ROHM Semiconductor, designed for direct connection to a serial port. It supports electrical erasure and writing in word units, utilizing four operation commands. Communication is managed through CS, SK, DI, and DO pins, with WC pin control enabling a write-disabled state for one-time ROM applications. The device features automatic erase-before-write functionality and low current consumption.
Key electrical specifications include a wide operating voltage range of -0.3 to 7.0V, with a maximum power dissipation of 500mW. The memory configuration is 256 words by 16 bits. It offers low active current consumption of 1.5mA (max.) at 3V and a standby current of 2μA (max.) at 3V. The EEPROM is built to withstand 100,000 erase/write cycles and provides 10 years of data retention.
Environmental specifications include an operating temperature range of -40 to 85°C and a storage temperature range of -65 to 125°C. The input voltage range is -0.3 to VCC+0.3V. The BR9040-W is available in a compact DIP-8 package, suitable for through-hole mounting.
This serial EEPROM is designed for applications requiring reliable data storage and easy serial interface integration. Its features make it suitable for various embedded systems and data logging tasks.
