The R1EX24016ATAS0I#S0 is a Renesas serial EEPROM offering 16K-bit of non-volatile storage organized as 2K x 8, supplied in an 8-pin TSSOP package on tape and reel. It uses a 2-wire I2C serial interface running at up to 400k Hz, so it occupies only two host pins regardless of density. The part is specified over a -40C to +85C industrial operating temperature range and is RoHS compliant. The R1EX24016ATAS0I#S0 supports 2.5V, 3.3V and 5V rails per its product designation.

Serial EEPROM of this size is used for configuration and calibration storage rather than program execution: board serial numbers, trim and offset constants, user settings, error and event counters, and small lookup tables that must survive a power cycle. The two-wire I2C interface lets the R1EX24016ATAS0I#S0 share a bus with sensors and real-time clocks, which is why it appears in industrial controllers, metering equipment, appliances, medical instruments, and automotive-adjacent modules. The 8-pin TSSOP footprint and -40C to +85C rating suit compact industrial boards. Buyers are typically embedded design teams and contract manufacturers standardising on a small, byte-writable non-volatile store.
