The AT45DB041B-RI from Microchip Technology is a 4-megabit SPI-compatible serial interface Flash memory. It is organized into 2048 pages, with each page containing 264 bytes, totaling 4,325,376 bits of memory. This device is well-suited for various digital storage applications, including voice, image, and program code storage.
Key electrical characteristics include a maximum clock frequency of 20 MHz and a supply voltage range of 2.7V to 3.6V. It supports page program operations with a single cycle reprogram capability (erase and program). The memory interface is Serial Peripheral Interface (SPI), facilitating efficient data transfer. The device also includes two 264-byte SRAM data buffers, allowing data reception while reprogramming the main Flash memory array.
Designed for surface mounting, the AT45DB041B-RI comes in a 28-SOIC package. It operates within a temperature range of -40°C to 85°C (TC). The device offers low power dissipation, with a typical active read current of 4 mA and a typical CMOS standby current of 2 µA. Its 5.0V-tolerant inputs enhance system flexibility. Note that this part is referenced as obsolete and not advised for new designs, with AT45DB041D recommended for new designs.
