W25Q80EWZPIG

W25Q80EWZPIG Application Field and Working Principle

The W25Q80EWZPIG is a conventional memory integrated circuit, designed and developed by Winbond. It is 8-pin, 1.8V flash memory, operating at operating temperature range from -40 Celsius to 85 Celsius. It has a maximum clock frequency of 104 MHz and the typical access time of 70ns. It is composed of a memory array and I/O control logic, along with a 5-pin SPI (Serial Peripheral Interface) interface. It is a high-performance, low-power alternative to a variety of memory solutions, such as EEPROM, NAND, NOR and SRAM.

Application Field

The W25Q80EWZPIG can be used in a wide range of applications, such as tablets, portable navigation systems, GPS, mobile phones, embedded video systems and digital cameras. Its wide operational voltage range, high reliability, low-power consumption and small size makes it an ideal solution for these applications.

The W25Q80EWZPIG also offers a high-speed performance, data read/write and program/erase capabilities, making it a perfect choice for non-volatile storage. The on-chip erase and program functions are performed by a high-voltage gate oxide transitor (HVGO), which is more effective and faster than flash memory. Furthermore, a write-protection feature is also embedded in the chip to prevent accidental write operations.

Working Principle

The W25Q80EWZPIG utilizes a single-bit interface with D-input, serial clock input and chip select (CS#) signal to initiate the read/write operations. The Read/Write operations are performed by sending and receiving data over the SPI interface. A write-protection feature is also implemented in the circuit, preventing accidental write operations. The erase/program operations of the memory is managed by a HVGO gate oxide transistor.

The chip features block-level erase, program and write protect functions. A minimum of 8K-byte data is required to be erased in order to perform the program operation. The chip also offers an auto erase feature, which erases the occupied memory at the start of a write command. The memory is accessed through either a CFI or SFI-compliant SPI interface, with a maximum clock frequency of 104MHz.

Conclusion

The W25Q80EWZPIG is a popular low-power, high-performance memory integrated circiut, ideal for a wide variety of applications. Its on-chip erase and program functions, backed with a write-protection feature, makes it a reliable solution for non-volatile storage. Additionally, a single-bit interface, along with read/write, program and erase operations, makes it a perfect choice for embedded video systems, digital cameras, mobile phones, etc.
