Epson develops RX-8571 series of real time clock module

Epson Toyocom, a provider of imaging products including crystal devices, has developed the RX-8571 series real time clock module, which has the lowest current consumption.

The RX-8571 series real time clock module leverages the low leakage current of an integrated IC based on the complementary metal-oxide-semiconductor process and the advantages of a monolithic crystal structure in an optimized combination of crystal unit and oscillator circuit to achieve a current consumption of 200 nA (typical), about 30% lower than conventional products.

The RX-8571 series contain 128-bit RAM, a 65,000-hour timer, low power detection, and output enabled 32.768 kHz output. The embedded tuning-fork crystal unit developed with Quartz Microelectromechanical Systems technology ensures ultra-low current consumption in a compact size. Three types are available, the LC package (3.6 x 2.8 x 1.2t mm), NB (6.3 x 5.0 x 1.3t mm), and SA (10.1 x 7.4 x 3.2t mm).

Epson claims that this product will contribute to extending the life of products with built-in batteries, and to increasing efficiency and making products smaller by reducing the capacitor and battery capacity required for power supply backup.
