M27V160-100K1: Application Field and Working Principle

Introduction

The M27V160-100K1 is an 8Mbit, 1Mb Serial Flash Memory from STMicroelectronics. It is an efficient and reliable memory solution for a wide range of applications, from automotive systems to handheld devices, and can work in temperatures ranging from –40℃ to +85℃. The M27V160-100K1 is a SPI-compatible (Serial Peripheral Interface) device, and is designed to have low power consumption and fast write-times. The organization of the M27V160-100K1 memory array is based on 16Kbyte sectors, and the device is organized into 8Mbit, made up of a total of 512Kbits x 32-bit words.

Application Field

The M27V160-100K1 is a highly reliable, low power consuming serial Flash memory, and only requires a few external components to operate. Therefore, it is an ideal memory solution for automotive applications, such as HEV or EV system control and vehicle information systems. It is also suitable for use in industrial automation systems and medical equipment. Furthermore, the M27V160-100K1 can also be used in numerous handheld devices, like GPS receivers, electronic locks and access control systems.

Working Principle

The M27V160-100K1 has two main operation modes: direct operation mode and single-transaction operation mode. In direct operation mode, information is transferred through the SPSSI and HOLD/WP pins and the data is received by the device on the rising edge of SCLK. A write cycle begins when the WRITE command (0×02) is issued followed by 1 to n address bytes, as many data bytes as are required and then the End Write command (0x95) is issued. In single-transaction mode, the Sfps single-transaction interface is used to facilitate communication. Data is transferred with a dedicated set of single-transaction write commands and read commands. The M27V160-100K1 also has advanced security features, such as user-defined identification codes, physical write-protect pins and reset commands, as well as multiple command sequences for read and write operations. To prevent accidental erasing or writing of data, the device has a number of built-in safeguards, such as an erase/write protection layer and a program verification check.

Conclusion

The M27V160-100K1 is a highly reliable, low power consuming serial Flash memory which is ideally suited to almost any application, from automotive systems to handheld devices. With its wide industrial temperature range, advanced security features and high speed write capabilities, it offers an efficient and reliable memory solution.
