[Chip versions A, B, and C]
Note 1. The lower-limit frequency of FCLK is 4 MHz during programming or erasing of the flash memory.
Note 2. The lower-limit frequency of PCLKD is 1 MHz when the A/D converter is in use.
[Chip versions A, B, and C]
Note 1. The VCC is 2.7 to 5.5 V and the lower-limit frequency of FCLK is 4 MHz during programming or erasing of the flash memory.
Note 2. The lower-limit frequency of PCLKD is 1 MHz when the A/D converter is in use.
[Chip versions A, B, and C]
Note 1. The VCC is 1.62 to 3.6 V and the lower-limit frequency of FCLK is 4 MHz during programming or erasing of the flash memory.
Note 2. The lower-limit frequency of PCLKD is 1 MHz when the A/D converter is in use.
