STMicroelectronics M28W160BT-100ZB6 Flash Memory

The M28W160BT-100ZB6 is a high-performance 16Mbit (1M x 16) non-volatile flash memory module designed and manufactured by STMicroelectronics. This robust flash memory product offers an optimal storage solution for a wide range of applications that require fast access times, high reliability, and the flexibility of in-system programmability. With its boot block architecture, the M28W160BT-100ZB6 is particularly well-suited for use in automotive, industrial, and telecommunications systems where the integrity of the boot code is of paramount importance.

Key features of the M28W160BT-100ZB6 include a fast read access time of 100ns, which allows for high-speed operation in critical applications. The device operates over a wide supply voltage range of 2.7V to 3.6V, making it versatile for use in systems with varying power supplies. Additionally, the memory is organized as 64 blocks of 256Kb each, providing a well-structured and easy-to-manage memory map.

One of the standout attributes of this flash memory is its boot block feature. The memory is divided into a top boot block and a bottom boot block, which can be used for storing secure boot code or other critical data that requires protection against inadvertent write or erase operations. The boot blocks can be locked down to prevent accidental alteration, ensuring the integrity and reliability of the system's firmware.

For programming and erasure, the M28W160BT-100ZB6 supports a flexible and efficient command interface. The device can be programmed either in the factory or in the field via standard microprocessor write timings, without the need for additional programming voltage. This simplifies the system design and reduces the overall cost of the system. The chip erase function allows users to erase the entire chip at once, making it convenient for updates and maintenance.

The M28W160BT-100ZB6 is packaged in a 48-ball TFBGA (Thin Fine-Pitch Ball Grid Array) package, which ensures a compact footprint and excellent thermal performance. This package is ideal for space-constrained applications where board real estate is at a premium. STMicroelectronics' commitment to quality and reliability is evident in the design and manufacturing of this flash memory, making it a trusted choice for designers and engineers looking for a dependable storage solution.
