S29AL016J70TFI020 is a 16Mbit (16 megabit) NOR flash memory chip, featuring a 48-pin TSOP package. This device is part of the "3.0V Only" boot sector flash memory series. It can perform read, programming and erasing operations under standard 2.7V to 3.6V single power supply without the need for an additional 12.0V programming voltage.
Its storage space can be flexibly configured as 2M x 8 bits (byte mode) or 1M x 16 bits (word mode) to meet different data bus width requirements. This chip communicates through a parallel interface, with a fast access time of 70ns and operates in an asynchronous manner.
This device is optimized for medium-capacity embedded applications that require code storage and program execution. It offers features such as sector erasure architecture (including a top or bottom sector for booting the code), hardware write protection, etc. The data can be effectively retained for 20 years and the erase life is up to 1 million times. The operating temperature range is from -40°C to +85°C.
