Epson crystal vibration released the RTC module crystal vibration

 Epson crystal vibration has always been "provincial, small, fine" technology as the senior core, and has established an original vertically integrated manufacturing model, can create unique core technology and equipment, using these as the base planning and design to provide unique value of products.

 Seiko Epson, the world's leading quartz crystal technology, has launched RA8804CE and RX8804CE, two new real-time clock (RTC) modules, and built-in digital temperature filling crystal oscillator (DTCXO). The real-time clock module is a single package product with a real-time clock IC with clock, calendar and other functions as well as an integrated 32.768 k crystal vibration unit. Not only can these modules benefit users by eliminating the need to design oscillator circuits and adjust the accuracy of the clock, their small size and integration also allow customers to use their circuit board space more efficiently.

 The new RTC module is installed in Epson's smallest RTC package (3.2×2.5×1.0tmm). RA8804CE Designed for automotive applications that meet the AEC-Q100 standard, the RX8804CE is designed for industrial systems. Both provide high precision timing in an electronic system, while meeting the requirements of small size and low current consumption.

 Today's industrial equipment, such as smart grid equipment, pay-per-click systems, security systems, and countless other systems and applications all operate based on time information, so it must be kept accurately. High precision tracking of time and date information in devices installed in vehicles, outdoor and other systems exposed to extreme ambient temperatures, in addition, the increasing demand for RTC modules is increasing due to the accelerated integration and miniaturization of electronic devices and the increasing desire to reduce their environmental footprint.

 However, in general, higher accuracy tends to be at the cost of higher power consumption, making it difficult to maintain or improve the accuracy of real-time clocks constructed by combining crystal units, oscillating circuits and timing IC. For the new module, Epson successfully reduced the power consumption and expanded the operating temperature range of the new module. This is achieved by making small and precise sound fork crystal units and using a new circuit design so that the crystal unit is driven by low power consumption.

The new RA8804CE and RX8804CE consume 0.35 μ A of current, 50% lower than the 0.7 μ A consumed by the RX8900CE (the earlier equivalent EpsonRTC module). The maximum operating temperature was expanded from 85℃ to 105℃. In addition, these modules are equipped with an extended number of programmable outage functions, timestamps, and a 24-bit timer. These new features reduce the burden of the CPU.
