Cymbet Corp. has developed an all-solid-state device that combines a Real Time Clock chip, EnerChip solid state rechargeable battery, and power management integrated circuit (PMIC) in a tiny 5x5-mm plastic package.

The second device is the CBC34523, which combines the NXP PCF8523 I2C bus RTC with an EnerChip and PMIC.
