• Manufacturer: Renesas Electronics America

Specifications of M37549T-RLSS

• Lead Free Status / RoHS Status: Supplier Unconfirmed

This product has two oscillator circuit patterns for the main clock XIN and sub-clock XCIN. The oscillator circuit on the user system
may not work properly because the oscillator circuit pin of the emulator MCU is not close enough to the oscillator circuit of the user
system. In this case, mount the oscillator circuit on the oscillator circuit pattern of the M37549T-RLSS.
Figures 3, 4 and 5 show the M37549T-RLSS circuit pattern and diagram.
7. Precautions
Notes on This Product:
Figure 3 When a ceramic oscillator with built-in capacitor is used for Xin/Xout
Figure 4 When a ceramic oscillator without built-in capacitor is used for Xin/Xout
Figure 5 When Xcin/Xcout is used as a circuit
