Standard product:
−40 to +85°C
Standard product, (A) grade product: −40 to +85°C
(A2) grade product: −40 to +125°C
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. The product without A/D converter (
μ PD78F95xx) is provided for the 78K0S/KU1+ and 78K0S/KY1+
respectively.
5. There are 2 and 4 factors for the products without A/D converter in the 78K0S/KU1+ and 78K0S/KY1+,
respectively.
