35-nA RTC integrates solid state battery
Cymbet Corporation (Elk River, MN) announced the commercial release of the EnerChip RTC product family that combines an ultra-low power real time clock with a rechargeable solid state battery and power management IC in a single 5-mm x 5-mm plastic package. The EnerChip RTC is presented as the world’s smallest RTC with integrated power holdover. This is accomplished by integrating bare die RTC, EnerChip battery and PMIC devices into a tiny package that uses Surface Mount Technology (SMT) and reflow solder processes. EnerChip RTC product family power usage ranges from 35 nA to 125 nA depending on clocking mode and can provide over 100 hours of RTC power back-up per charge with thousands of recharge cycles. The EnerChip RTC is positioned as a replacement for bulky and troublesome coin cell batteries and supercapacitors.
The first three devices in the EnerChip RTC product family are:
- CBC34123 that combines an NXP RTC with the EnerChip and PMIC for 30 hours power holdover and supports SPI-bus.
- CBC34803 that that combines an Ambiq RTC with the EnerChip and PMIC for 100 hours power holdover and supports I2C-bus
- CBC34813 that that combines an Ambiq RTC with the EnerChip and PMIC for 100 hours power holdover and supports SPI-bus
