JS28F320C3BD70A

The JS28F320C3BD70A is a flash Enhanced-PSP (E-PSP) memory device manufactured by STMicroelectronics. It is a 32 megabit (4 megabyte) NOR flash memory device with a 3.0V single supply voltage and a 0.18µm process technology. It uses a sector-erase architecture, which allows for flexible and reliable boot code storage. The device also has a Command-Programmed page size of 256 bytes, which allows for fast programming times and better reliability.

The JS28F320C3BD70A is perfect for applications in automotive, medical, industrial, communications, data logging and other markets that require both reliable and cost efficient storage devices. Its features include an advanced error checking and correction system, written data validator, programmable write protect, extended temperature range, and fast programming times.

In terms of its working principle, the JS28F320C3BD70A uses a sector-erase architecture, which allows for reliable boot-code storage as well as flexibility when programming the device. In this architecture, the entire device is broken down into smaller number of independently erasable sectors. Each sector can be erased in milliseconds and reprogrammed with valid code, making sure that only valid code can be written in each sector. This helps to ensure the integrity of the stored code and data, allowing for more reliable and efficient functioning.

The device is also protected by a write-protect feature, which prevents accidental overwriting of the stored code and data. This helps to ensure that the device is not damaged by inadvertent programming and other events. The device also contains error correction, written data validator, and chip-level versioning features that help to ensure the reliability, security, and robustness of the stored data.

Overall, the JS28F320C3BD70A is perfect for applications requiring reliable and cost-effective memory storage. It offers advanced features such as sector-erase architecture, error correction and written data validator, among others, that help to ensure the reliability and robustness of the stored data. With these features, the JS28F320C3BD70A is an ideal choice for automotive, medical, industrial, data logging and many other markets.
