Smallest real time clock module

EPSON, represented by TE Australia , has developed one of the smallest real-time clock modules (only 3.6mm x 2.4mm x 1.1mm) for use in mobile equipment with a new type of package.

The new models were developed by combining Epson's original plastic-moulding technology with its technology for ultra-compact ceramic packaged crystal units. The new construction conforms to the real-time clock module with a built-in crystal unit.

The demand for smaller and less-power-consuming electronic devices is expected to grow as mobile communication equipment becomes smaller. Epson's new devices meet this challenge, successfully achieving miniaturisation and micro-fabrication of ICs without sacrificing frequency stability.

The RX-4574LC represents a further miniaturisation of the RTC-4574 series modules. Because of software compatibility the move to smaller devices can be made with greater ease.

Like Epson's earlier models of real-time clock modules, the RX-4574LC can be built as a package along with crystal units, oscillating ICs, and crystal clock ICs to provide manufacturing customers with not only adjustment-free devices featuring stable frequencies but also more efficient use of limited space and enhanced reliability.
