Notes 1.
Use these products in the following voltage range because the detection voltage (VPOC) of the power-on-
clear (POC) circuit is the supply voltage range.
Standard product, (A) grade product: 2.2 to 5.5 V, (A2) grade product: 2.26 to 5.5 V
2.
μ PD78F950x does not support the crystal/ceramic oscillation.
3.
The product without A/D converter (
μ PD78F950x) in the 78K0S/KU1+ is not supported.
4.
