Cymbet Corporation’s Low Power CBC921 Real-Time Clock and Power Management Component is in Production and Now in Stock

Minneapolis, MN – September 16, 2019 – Cymbet Corporation announced that its latest low power product – the CBC921 Power Management with RTC (PMRTC) integrated circuit – has been fully qualified and is now in volume production and in stock at Digi-Key and other authorized distributors. CBC-EVAL-14 evaluation boards supporting application development are also available, in both 3.2V and 4.1V battery backup options. The CBC921 is the first device architected by Cymbet to meet market needs in a high volume, standard process technology.

This new product integrates an ultra-low power Real Time Clock (RTC) with power management and power switching optimized for energy-efficient wireless devices such as low power sensors in industrial, medical, and consumer applications. This product family supports charging voltage options for a variety of backup power sources including rechargeable coin cells, supercapacitors, as well as Cymbet’s unique solid state thin film battery – the EnerChip™. The CBC921 offers best-in-class operating current, configurable battery management, power switching, and an on-chip temperature sensor. It is available now in a 3mm x 3mm x 0.55mm 16-lead MLPQ surface mount package. Bare die are also available, allowing designers to embed the chip into RFID and asset tracking tags, smart cards, body-worn patches, miniature sensors, and other low profile products. The bare die option allows for integration with Cymbet’s bare die EnerChip batteries for completely integrated “batteryless” products

Key features of the new product include:

  •     Ultra-low power Real-Time Clock (RTC) with power-fail detect and battery management
  •     15-20nA RTC using internal RC oscillator
  •     50nA RTC using crystal oscillator
  •     Low power timer and power manager with integrated power switch extend run time in battery-powered systems
  •     Programmable battery management function controls 4.1V Li batteries and 3.2V coin cells and supercapacitors
  •     Alarm capability on all counters
  •     Configurable multi-use outputs for interrupts, output clock, and managing power to external devices
  •     64 bytes of RAM
  •     Internal temperature measurement with 10-bit ADC enables oscillator compensation and temperature sensing
  •     Advanced crystal calibration to ± 1 ppm
  •     Ultra-low Iq VIN POR circuit (< 25nA)
  •     Temperature range -40°C to +85°C
  •     Serial communication: I2C-bus available now; SPI-bus optional


  •     Wireless sensors, RFID tags, and other low duty cycle applications
  •     Business and industrial systems such as: network routers, point-of-sale terminals, and single-board computers
  •     Test equipment, multi-function printers, industrial controllers, appliances, and utility meters
  •     Wearable, Internet of Things (IoT), and other battery-powered products requiring low power consumption

Coming soon: The next generation of integrated products from Cymbet – the iRTC – which combines the PMRTC and EnerChip solid state battery into a single, low profile surface mount package, will be sampling in Q4 2019.
