FAQ NO : 1000265 Issue Date : Dec.22.10 Functions : USB When using the SH family MCU USB as the USB function module, and the power is not supplied to the MCU, is it possible to connect the USB connector to the USB host and the power is supplied only to the VBUS pin (Apply the voltage to the VBUS pin of the MCU)... Such operation does not affect the MCU. Relevant Products SH7266, SH7267 SH7265 SH7263 SH7262, SH7264 SH7205 SH7203 SH7670
FAQ NO : 107526 Issue Date : Sep.28.09 Functions : I/O Port Which pins have Weak Keeper Circuit? And can it select Enable/Disable? Please refer Section 19.6 Usage Note in the hardware Manual. You can not select Enable/Disable. The weak keeper circuit is always Enable. Relevant Products SH7619
FAQ NO : 107524 Issue Date : Sep.28.09 Functions : Ethernet The Clock for PHY is selectable whether Internal clock or External clock. How to decide the selection ? Jitters of the differential transmit output pins (TxP and TxM) depend on the jitter of the original clock. Thus, they can be reduced by using an external clock if its jitter characteristic is better. Please note that if the jitter characteristic of t... Relevant Products SH7619
FAQ NO : 107521 Issue Date : Sep.28.09 Functions : Ethernet What is the recommended Pulse Transformer which is a RJ-45 connector separated type? S558-5999-46-F (BellFuse) has been tested on Renesas boards. Relevant Products SH7619
FAQ NO : 107530 Issue Date : Sep.28.09 Functions : Ethernet , I/O Port In Internal PHY usage, in the case that it connects PC18(it is multiplexed with LINKSTA) to a device as IO port, can it check the link status of Internal PHY module using PHY status register (PSR)? Yes, it can. LINKSTA (PC18) pin of EtherC is connected with LINK output of Internal PHY in SH7169 internal circuit. Relevant Products SH7619
FAQ NO : 107529 Issue Date : Sep.28.09 Functions : Ethernet Is there any method to check link status without checking bit 2 (Link Status) in the SMI status registers (register #1)? It is possible to detect the change of Link signal by the interruption. Please use following method. 1. Set "1" at bit 22 (ECIIP) in EtherC/E-DMAC Interruption Enable Register (EESIPR). 2. Set "1" at bit 2 (LCHNGIP) in EtherC Interrup... Relevant Products SH7619
FAQ NO : 107538 Issue Date : Sep.28.09 Functions : Ethernet How is SH767x Ethernet transfer speed? Ethernet transfer speed depends on driver software, the TCP/IP protocol stack software, and evaluation conditions. The following maximum speeds were observed during testing by Renesas. They are provided as reference values only, and are not guarantee... Relevant Products SH7670
FAQ NO : 107537 Issue Date : Sep.28.09 Functions : General MPU/MCU What procedure does it need to get the SD Host Interface Specification (SDHI) on Section 18 in the hardware manual ? For users of the SDHI on Renesas products such as the SH7671/SH7673 (SH7670 Series), SoC products, etc. , Renesas will confirm whether you have an SD Host/Ancillary Product License Agreement (HALA) with the SD Consortium, and then request an NDA for ...
