New 35nA RTC with Integrated EnerChip Battery

Combines ultra low power RTC with Solid State Battery and PMIC in Tiny Package

Cymbet announced today 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 5mm x 5mm plastic package. The EnerChip RTC is the world’s smallest RTC with integrated power holdover. This is accomplished by utilizing bare die RTC, EnerChip battery and PMIC devices combined into a single package that uses Surface Mount Technology (SMT) and reflow solder processes. EnerChip RTCs provide from 30 to over 100 hours of RTC power back-up per charge with thousands of recharge cycles. The EnerChip RTC is an ideal replacement for bulky and troublesome coin cell batteries and supercapacitors.

“The life-of-product EnerChip RTC enables our customers create new product designs and form factors,” said Bill Priesmeyer, Cymbet President and CEO. “Placing an ultra-low power EnerChip RTC in a tiny space anywhere on the board drives innovative products, increases quality and lowers warranty costs.”

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

The various EnerChip RTC configurations support: Alarm and timer functions, General Purpose Outputs, XT Oscillator, 256B RAM, Calibration/Auto-calibration, RC Oscillator, Watchdog, External Interrupts, a VBAT switch, and on-chip battery charge control with power management.

Additionally, each EnerChip RTC device has a CBC-EVAL-12 evaluation kit that utilizes a USB interface with the EnerChip RTC on a small removable tab board and a PC-based Graphical User Interface that provides full register read/write access on the EnerChip RTC.
