NOTES:
1. Referenced to VCC = 3.0 to 5.5V at Topr = –40 to 85°C unless
otherwise specified.
2. Relationship between main clock oscillation frequency and supply

3. Execute program/erase of flash memory by VCC = 3.3 ± 0.3 V or
VCC = 5.0 ± 0.5 V.
4. When using over 16MHz, use PLL clock. PLL clock oscillation
frequency which can be used is 16MHz, 20MHz or 24MHz.
