Package
30-pin plastic SSOP (7.62 mm (300))
Notes 1. Select either of the functions of these alternate-function pins.
2. Use the product in a voltage range of 2.2 to 5.5 V because the detection voltage (V
POC
) of the power-on-
clear (POC) circuit is 2.1 V
±
0.1 V.
Caution The operating voltage range may be changed after evaluation of the device.
