Intel JS28F320B3BD70: A Comprehensive Overview of the 32Mb 3V Bulk Erase Flash Memory

The Intel JS28F320B3BD70 represents a significant component in the landscape of non-volatile memory solutions, designed for systems requiring reliable and robust storage. As a 32-megabit (4MB), 3.0-volt single power supply flash memory chip, it is engineered for applications where durability, performance, and ease of integration are paramount. This device is packaged in a Bulk Erase configuration, enabling the entire memory array to be erased in a single, efficient operation, which is a critical feature for firmware updates and system reprogramming.

Fabricated with Intel's advanced flash technology, the JS28F320B3BD70 offers a versatile asymmetric block architecture. This includes one 16-Kbyte parameter block and two 8-Kbyte parameter blocks, alongside multiple main blocks, providing flexibility for storing both code and data. The chip supports a standard memory interface for easy integration into existing system designs, making it suitable for a wide range of applications from telecommunications and networking equipment to industrial control systems and automotive electronics.

A key feature of this memory chip is its high-performance read and write operations. It supports a fast page read mode, significantly accelerating data access times. The write and erase functions are managed through a command user interface (CUI), which simplifies programming and control through a series of standardized instructions. This interface allows for block locking to protect critical data from accidental modification, enhancing system security and integrity.

The device operates over a wide industrial temperature range, ensuring reliability in harsh environments. Its low power consumption in both active and standby modes makes it an excellent choice for power-sensitive applications. Furthermore, the JS28F320B3BD70 incorporates advanced data protection mechanisms, including a write protection pin and a power transition write inhibition feature, safeguarding data during unexpected power fluctuations.
