Notes: 1. The VDDQ (3.3. V), VSSQ, VDD (1.8 V), and VSS pins must all be connected to the
system power supply, and power must be supplied continuously. Even if only the RTC
is operating (in standby mode), power must be supplied to all VDDQ, VSSQ, VDD, and
VSS pins, in the same way as for VDD-RTC and VSS-RTC.
2. Power must be supplied to VDD-PLL1/2 and VSS-PLL1/2 regardless of whether or not
the on-chip PLL circuits are used.
3. Power must be supplied to VDD-CPG and VSS-CPG regardless of whether or not the
on-chip crystal resonator is used.
4. Power must be supplied to VDD-RTC and VSS-RTC regardless of whether or not the
on-chip RTC is used.
5. VSSQ, VSS, VSS-RTC, VSS-PLL1/2, and VSS-CPG are not connected inside the
package.
6. The 5'5, RD/:55, CKIO2, and &.,25(1% pins are not provided on the QFP
package.
7. With the QFP package, the maximum external bus operating frequency is 83 MHz.
