Real time clock modules in 2.7x2.5x0.9-mm HTCC package

January 16, 2013 // By Julien Happich
MSC now offers four new real time clock (RTC) modules in C3 package from Micro Crystal. The modules measure only 2.7x2.5x0.9mm.

The RTC module types RV-3029-C3 and RV-3049-C3 with an embedded 32.768 kHz crystal and integrated temperature compensation are specified for an operating temperature of up to +125°C. An accuracy of ±6 ppm is guaranteed from -40°C to +85°C.

Current consumption of the low-power RTC module type RV-8564-C3 is only 250nA at 3 V supply voltage. The ultra-low-power RTC module type RV-8523-C3 has an even lower current consumption of only 130nA. As with the larger C2 high temperature co-fired ceramic (HTCC) package versions, the new more compact C3 versions can be operated with supply voltages of 1.2 V/1.3 V to 5.5 V. All other electrical parameters are also compatible with previous versions. The new RTC modules in C3 package are qualified according to AEC-Q200, RoHS compliant and 100% lead free.
