The JS28F512M29EWLA is an electrically erasable programmable read-only memory (EEPROM) device from the 28F family. It features Electrically Erasable Programmable Read-Only Memory (EEPROM) technology with a flexible range of write-once, read-many architectures. This technology is well-suited for embedded applications requiring the storage of data that can be accessed multiple times without sacrificing performance or occupying large spaces on a printed circuit board (PCB).

Memory Category

The JS28F512M29EWLA is a non-volatile memory device, meaning it is able to retain data even when the power supply is removed. It belongs to the memory category as its primary function is to store data. Its small size and low power consumption makes it a suitable choice for applications where size and power consumption are of great relevance. The device is available in a variety of packages, ranging from 16-pin small outline (SOIC) to 44-pin thin small outline package (TSOP).

Application Field

The JS28F512M29EWLA is typically used in data logging, security/authentication systems, metering, instrument calibration/assessment, and industrial control. Its serial capacity and extremely low current consumption makes it suitable for use in small, slim devices. This makes it ideal for applications where size and power conservation is of prime importance.

The memory is also used in digital signal processor (DSP) applications, telecommunications and networking, process control and embedded systems, automotive, medical and consumer electronics applications. Its flexibility in terms of architecture makes it suitable for any complex systems where data has to be stored.

Working Principle

The JS28F512M29EWLA device consists of 512Kbits of electrically erasable programmable read-only memory (EEPROM). It allows the user to store data in nonvolatile memory in the form of bits. The device uses a triple-well process technology, making it more robust and flexible than other nonvolatile memories like Flash. It also features an optional boot block lock bit configuration, which allows users to protect the data stored in boot block memory.

The device is capable of carrying out multiple reads and writes per hour and is capable of accessing data at higher speeds than Flash. It has a high density of 128Kbyte, 544bytes per sector, and each row is 64bits wide. These features make it ideal for high speed transmission, data logging and authentication.

The device can operate at a maximum supply voltage of 5.0V and operates over a temperature range of -40°C to +85°C. It contains emission reduction circuitry, allowing it to meet the requirements for Class B immunity for both emissions and susceptibility. The device is also RoHS compliant making it suitable for use in consumer electronic products.

Conclusion

The JS28F512M29EWLA is an EEPROM device from the 28F family. It features Electrically Erasable Programmable Read-Only Memory (EEPROM) technology with a flexible range of write-once, read-many architectures, suitable for applications where size and power consumption are of great relevance. This memory device is non-volatile and usually used for data logging, security/authentication systems, metering, instrument calibration/assessment, and industrial control. Its triple well process technology and optional boot block lock bit configuration makes it reliable and secure for complex systems. Its maximum supply voltage of 5.0V, operating temperature of -40°C to +85°C and RoHS compliance makes it an ideal choice for consumer electronic products.
