1. Referenced to VCC = 4.2 to 5.5V at Topr = –40 to 85°C unless
otherwise specified.
2. Relationship between main clock oscillation frequency and supply

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