1. All devices are production tested at TA = +25ï°C and are guaranteed by design for TA = â40ï°C to +85ï°C.
2. Digital inputs CS and U/D are connected to GND or VDD.
3. Digital timing is guaranteed by design, not production tested.
4. Power-up time is the period of time from when the power supply is applied until the serial interface is ready for writing.
