Memory products have come a long way since their inception almost half a century ago. Memory technologies have been evolving rapidly, allowing for faster speeds and denser capacities. BR24L04-W is the latest generation of Ultra Low Power Serial EEPROM memory chips from STMicroelectronics. It is designed to operate in a wide range of electrically and thermally demanding applications.

The BR24L04-W is a 4-wire Serial EEPROM memory chip based on the I²C-bus protocol. It is designed for low power applications, with a very low data retention current of only 250nA at 25°C and a supply voltage range of 1.8V to 5.5V. The device can operate at temperatures between -40°C to +85°C. The device offers 4k-bit of memory and is available in an 8-pin SOIC package.

The BR24L04-W offers several features that make it suitable for a wide range of applications. It has a Page Write feature which allows writing of up to 64 bytes at once. This reduces the time spent writing data and also increases power efficiency. It also has BlockWrite protection which provides an additional level of protection against inadvertent data corruption. BlockWrite allows the memory to be write protected in specific locations or across the entire memory. The device also provides a built-in ECC for checking and correcting data integrity.

The BR24L04-W also features a Low Power Modes which reduces power consumption by up to 90%. This is accomplished by reducing the clock frequency and putting the part into a low power sleep mode. The device can also be put into an Ultra Low Power Sleep Mode which further reduces power consumption by up to 98%. This mode is activated by setting the I²C-bus clock frequency to 0.33 kHz. In this mode the device will consume only 250nA of current.

The BR24L04-W is suitable for a wide range of applications including data logging and remote sensor applications. Its wide operating temperature range and low power consumption makes it a suitable choice for embedded applications. It is also suitable for applications such as medical electronics, industrial automation, automotive controllers, alarm systems and security systems. Its built-in ECC, BlockWrite protection and low power mode also make it suitable for memory intensive embedded applications.

In summary, the BR24L04-W is a 4-wire serial EEPROM memory chip from STMicroelectronics designed for low power applications. It offers features such as a Page Write feature, BlockWrite protection and built-in ECC. It also features a low power mode which reduces power consumption by up to 98%. The BR24L04-W is suitable for a wide range of applications including data logging, remote sensors and embedded applications. Its low power consumption and wide operating temperature range make it a suitable choice for a number of applications.
