The Renesas Electronics Corporation AT45DB161E-SHD-T is a 16-Mbit DataFlash memory chip designed for advanced storage needs in modern electronic applications. Operating within a voltage range of 2.3V to 3.6V, this memory device incorporates Serial Peripheral Interface (SPI) compatibility, supporting SPI modes 0 and 3 for efficient communication. Offering continuous read capabilities at speeds up to 85MHz, along with low-power read options, the chip delivers high-speed performance while maintaining energy efficiency. It also features configurable page sizes of 512 bytes or 528 bytes (default), allowing flexibility to meet different application requirements.
Equipped with two independent SRAM data buffers, the AT45DB161E-SHD-T facilitates seamless data operations, such as receiving new data while reprogramming the main memory array. With versatile programming and erase options—including page, block, sector, and full-chip erase capabilities—the chip is built for adaptability and convenience. Advanced data protection features like individual sector protection, sector lockdown, and a one-time programmable (OTP) security register ensure high security and reliability. Additionally, its energy-efficient design minimizes power usage, making it a practical choice for low-power applications.
