RX-8731LC RTC module from Epson Toyocom

Epson Toyocom Corp. has announced plans to launch volume production of a new, ultracompact real-time clock module. The RX-8731LC, engineered for use in devices such as portable media players, has a built-in ID-ROM for effective digital rights management (DRM).

In addition to basic calendar and timer functions, the RX-8731LC package integrates peripheral circuitry that supports ID-ROM, E2PROM, GPIOs and a multitude of other functions for digital players.

This module ships with an ID information written to the 48bit internal ID-ROM at the factory. The ID information can be used as a unique identifier for a specific device in DRM schemes, which encourage licensed distribution of digital contents and prevent their unauthorized copying and distribution. The RX-8731LC thus facilitates the embedding of ID information in digital players.

The package, which measures 3.6-by-2.8-by-1.2mm, is suitable for smaller devices. Meanwhile, the package also houses a QMEMS tuning fork crystal unit that eliminates the need for customer clock adjustments.

The modules will begin shipping June 2007.
