Memory, as a crucial part of computer, has developed into many forms such as Flash, ROM and DRAM. AT45DB161E-SSHF-B is one type of flash memory specially designed for embedded systems. Its superiority in power consumption, memory density and compatibility with many microcontrollers make it a popular choice to enterprises in quite a few areas.

Application

AT45DB161E-SSHF-B flash memory is widely used in embedded systems. For instance, due to its 8.0Mbits of memory density and fast memory access, this chip can be used to log telemetry data in high-speed applications. In addition, due to its low power consumption (1.4mA at 70MHz read access), this chip is suitable for portable device applications that require battery power.

Moreover, the low cost of manufacturing and low voltage requirements of this chip make it popularly used in human-machine interface applications such as control panels, remote controllers and touchscreen display systems. Besides, it also has a great compatibility with many microcontrollers like ARM Cortex-M0/M4 series, which make it a perfect choice for IoT applications.

Working Principle

The AT45DB161E-SSHF-B is a parallel-interface Flash memory that is characterized by low-power consumption, 2.7V-3.6V voltage range, 8Mbits of memory density, fast memory access and great compatibility with many microcontrollers. This chip offers uniform 4K bytes erasable sectors, 512 bytes erasable pages, and two multi-plane bytes erase/program mode which can be used to simultaneously program multiple words in one operation. The multibyte programming and the various erase/program setting enable the chip to achieve a high programming performance while still maintaining power efficiency.

Moreover, the AT45DB161E-SSHF-B is Single-Supply SPI Flash Memory with fast read access. It has a 200nS random-address-access cycle time and fast 6MHz clock in fast read mode. It also has a range of continuous read modes for low-power applications. In addition, it also provides an auto-erase features which can automatically erase the sector before programming, which is quite user-friendly.

Conclusion

In conclusion, AT45DB161E-SSHF-B flash memory is one type of flash memory that is suitable for various embedded system applications, such as telemetry data logging, portable device applications and human-machine interface applications. Its low power consumption, 2.7V-3.6V voltage range, 8Mbits of memory density, fast memory access and great compatibility with many microcontrollers make it a popular choice among enterprises.
