Note 1: All devices are production tested at TA = +25°C and are guaranteed by design for TA = -40°C to +85°C.
Note 2: Digital timing is guaranteed by design, not production tested.
Note 3: Power-up time is the period of time from when the power supply is applied until the serial interface is ready for writing.
Note 4: Digital inputs
CS and U/D are connected to GND or VDD.
