AT29LV040A-20TI Application Field

The AT29LV040A-20TI is a 4 Megabit (512K x 8) CMOS single-voltage flash memory device with a high speed read cycle time of 70ns. This device is widely used for a variety of applications, including desktop computers, digital cameras, portable audio players, digital TV receivers, navigation systems and other digital electronic devices. The device offers low power consumption and a wide operating temperature range, which make it well suited for a range of embedded applications.

The AT29LV040A-20TI is also used as a ROM replacement in embedded applications. It can hold up to 4 Megabits of data, which makes it ideal for applications such as embedded code storage and program storage. The device provides a simple, low-cost solution for data storage in embedded designs.

AT29LV040A-20TI Working Principle

The AT29LV040A-20TI is a non-volatile flash memory device that stores data on a memory chip. The chip is organized as 512K x 8 bits of non-volatile flash memory. The device is designed to provide fast access to data that is stored in the memory. The device also provides a simple and low-cost solution for data storage in embedded designs.

The device is powered by a single 3.3V power supply. When power is applied to the device, an internal logic circuit decodes the address and data inputs. The data is then written to or read from the memory array. The device also includes write and erase protection circuitry to prevent accidental data loss. The device also includes an optional Write-Protect (WP) pin that can be used to enable or disable the write and erase protection logic.

The device is equipped with a high speed page read cycle time of 70ns and a page write cycle time of up to 650µs. This enables the device to quickly read data from the flash memory and write it to the system. The device also includes a lockable boot block, which enables the device to be used in secure applications such as secure storage and code storage.

Conclusion

The AT29LV040A-20TI is a versatile and reliable flash memory device, which is widely used for a variety of applications. Its high speed read and programming cycle times, low power consumption, wide operating temperature range and lockable boot block make it well suited for embedded designs. The device offers a low-cost solution for data storage, code storage and program storage.
