The 70V24L20JGI8 is a type of semiconductor memory, specifically a CMOS non-volatile memory that has been developed to provide extremely low operating currents with a wide operating voltage range. It is a serial-access SIL (Single-In-Line) package with a two-wire interface, commonly referred to as the I2C protocol.

Application Field

The 70V24L20JGI8 is ideal for memory storage applications in stationary and mobile environments. For example, it can be used in life-critical and medical applications where reliability is essential, such as pacemakers and other medical implants. It is also suitable for automotive and consumer applications, offering a multiple of memory and address lines to provide longer addressing and higher data throughput, providing a greater range of memory applications.

Working Principle

The device employs a serial access method where a series of built-in registers are used to access memory. The registers are programmed through the I2C interface and provide information on the internal state of the device and input data. The device features a data ready flag which will indicate when data is ready to be read. Once data is read, the device will shift the address pointer automatically to the next sequential address.

The device utilizes a set of built-in control signals (such as write enable, read data, etc.) to control data access, write, and read. Data can be written from the serial port, I2C port, or from multiple address lines (running parallel to each other, in an interleaved manner). Data can be read from the contents of the registers. There is also the ability to write data to multiple addresses. The device features 128 bytes of EEPROM memory, allowing the user to store information such as addresses, settings, and other data.

The device has a small physical size, making it ideal for applications where space is limited. The device can draw as little as 10µA, providing power savings. It’s operating temperature range is from -40°C to 85°C and is rated for 100,000 write cycles.

Conclusion

The 70V24L20JGI8 is an ideal choice for applications requiring low operating currents with a wide operating voltage range and high performance. It is suitable for storing data for life-critical and medical applications, automotive, and consumer electronics. It offers the flexibility of multiple memory and address lines, higher data transfer rates, and a robust EEPROM memory. The device is also very small and power efficient, operating within a wide temperature range, and highly reliable, with a long write cycle life.
