Timing Devices (MEMS Resonator / Crystal Unit / Ceramic Resonator)MEMS resonators suitable for embedding in the IC

Value created by embedding in the IC

Murata's MEMS resonators use silicon materials that have high affinity with the IC, and realization of the world's smallest size enables embedding in the IC.
By embedding a 32k resonator in the IC, this eliminates the need for resonator technical support by the IC manufacturer, and helps to simplify the circuit at the end customer.

Value created by embedding 1.Reduced burden on technical support 2.Provision of added value to the end customer 3.Simple circuit design 4.Space saving (increased design flexibility)

The wafer level chip scale package (WLCSP) uses silicon materials that have high affinity when mounting with a semiconductor IC chip made of the same material. In addition, a profile 30% lower than that of a conventional crystal resonator realizes a product height of just 0.35 mm. This enables embedding in the IC.

Molding resistance

Murata's 32 kHz resonator has a WLCSP structure using silicon materials that provides excellent molding pressure resistance.
This enables to reduce package displacement during molding to approximately 1/100 that of a conventional crystal resonator, and high -pressure transfer molding can also be supported.

Molding simulation results
[Simulation conditions] Molded resin: epoxy, molding pressure: 19 MPa
