AT49F002T-90TC Working Principle

The AT49F002T-90TC device is based on a 32K Flash memory. It consists of two independently erasable memory planes, each plane with one sector that can be erased independently. The total size of the plane is 8 Kbytes. A sector is a defined area, with a specific size and organization, that can be erased without affecting adjacent memory blocks.

The device supports a small, low pin Serial Peripheral Interface (SPI) bus, allowing a fast interface to the host. Due to its low pin count, the AT49F002T-90TC can be used on a simple mainboard such as an Arduino Uno or a Raspberry Pi.

The device has a small form factor, which makes it ideal for applications where board space is limited. Furthermore, it has a standard-enabled interface, which allows for compatibility with a wide range of host systems.

AT49F002T-90TC has an on-chip write protection feature and a write inhibit (WRT) pin, which can be used to prevent unintentional programming. Data protection is also ensured by the built-in protection circuitry against overvoltage and write/erase cycles.

The AT49F002T-90TC is designed to consume low power, offering a very low standby current and high read endurance. These features make it suitable for battery-operated applications, or for devices that are in a sleep mode most of the time.

AT49F002T-90TC is an ideal choice for a wide range of embedded applications due to its low pin count, small form factor, excellent data protection, endurance and power consumption.
