Choice of RTC with SPI-bus or I2C-bus
EnerChip RTC CBC34123 uses an NXP PCF2123 Real Time
Clock with SPI-Bus. The EnerChip RTC CBC34803 uses an
Ambiq Micro AM0803 with I2C-Bus. The CBC34813 is SPIbus. All parts have an integrated EnerChip CBC005 5uAh
bare die rechargeable battery and CBC910 ultra low power
Power Management IC.
EnerChips are Safe and Certified to All Standards
EnerChip devices comply to all environmental, safety and
disposal standards. EnerChips are completely non-toxic and
