BR25H640FJ-2CE2 memory is a low cost, high-volume 16 megabit serial flash memory device that requires only one power supply voltage. It is widely used in embedded systems, mobile phones, wireless modules and other applications.This device supports instructions to read and write data, reduce power consumption and protect information stored in the memory. This device supports the 32-pin narrow width small outline package (N-SOIC®) with a width of 6mm and a height of 4.4mm.The device operates over an operating voltage range of 2.7 to 3.6V and has a single 3.0V supply. Its low power consumption allows it to be used in battery-operated products. The endurance and data retention remain reliable to stabilize under severe environmental conditions.The key features of BR25H640FJ-2CE2 are its high speed, high reliability, low power consumption and excellent performance. The device can read data at an operating frequency of up to 66 MHz and write data at an operating frequency of up to 22 MHz. The device has a wide temperature range of -20°C to +85°C.The device is particularly suitable for mobile products that require a high read speed and relatively moderate write speed, as well as design scenarios with a lower operating voltage. The device is also compatible with various protocols such as SPI, QSPI, SDIO, SSPI and SDXC.The BR25H640FJ-2CE2 operates according to the principle of erase before write methodology. This means that data must first be erased before it can be written to the device. The device supports page erase, sector erase and chip erase.The page erase can erase one or multiple pages at once. It has a minimal duration of 1 ms and a maximum duration of 6 ms.The sector erase operation can erase from one to four sectors at once. It has a minimal duration of 1 ms and a maximum duration of 26 ms.The chip erase operation can erase the entire device. It has a minimal duration of 9 ms and a maximum duration of 130 ms.The device also supports protection features such as write protection, sector protection, password protection and block protection. The write protect feature prevents data from being written without unlocking it first. The sector protect feature prevents data from being written to specific sectors without unlocking them first. The password protection feature prevents data from being written without entering the correct password. The block protection feature protects data in specific blocks from being written without unlocking them first.To summarize, the BR25H640FJ-2CE2 is a low cost, high-volume 16 megabit serial flash memory device that requires only one power supply voltage. It is widely used in embedded systems, mobile phones, wireless modules and other applications due to its high speed, high reliability, low power consumption and excellent performance. It supports a wide range of instructions to read and write data, reduce power consumption and protect information stored in the memory.
