Real-Time-Clock Modules for industrial applications
The RX8901CE and RX4901CE, two new RTC (real-time clock) modules for industrial applications, are now available to order by Seiko Epson Corporation.
This RTC modules are housed in a 3,2 mm x 2,5 mm x 1,0 mm package. I2C-Bus and SPI-Bus interfaces are supported by the RX8901CE and RX4901CE, respectively. Both can meet the requirements of low current consumption and tiny form factor while providing accurate timekeeping in electronic systems.
A 30% reduction in current consumption is seen in the new RX8901CE and RX4901CE compared to the RX8804CE (an older Epson RTC module) which used 0.35 µA (Typ.). The maximum number of time stamp recordings that might be retained was raised from one to thirty-two. In addition to providing an I2C-Bus interface, Epson ( electronica 2024, Hall C3, Booth 341) has increased the number of interface choices by providing an SPI-Bus interface.
