- Low power consumption of 3.5 m A typical at 1.8 V
- LVCMOS patible output
- Industry-standard packages: 2.5 x 2.0, 3.2 x 2.5 mm x mm
- Ro HS and REACH pliant, Pb-free, Halogen-free and Antimony-free
- For AEC-Q100 active resonators, refer to Si T1424 and Si T1425
Conditions for Drop-In-Replacement
- Si T1418 is designed to work with non-wireless MCUs except for BLE which is supported
- Si T1418 is footprint patible to 4-pad SMD Xtal resonators with electrically grounded pin 2 and 4
- MCU/µC supports external oscillator mode
- MCU/µC supports GPIO output function on XTAL1 pin
(Figure 18) and able to drive ~6 m A across 1.8 V to 3.3 V VDD continuous voltage
Applications
- Industrial, medical, non AEC-Q100 automotive, avionics and other high temperature applications
