- Application NoteAI-generated Summary: The 38K2 group USB function offers flexible endpoint transfer settings to match user applications, supporting various transfer types and directions with selectable buffer sizes and interrupt conditions. It simplifies USB signal and hub port management through interrupt routines. The external bus interface allows simultaneous CPU read/write and USB data receipt, using double buffer mode to reduce wait times. The 38K2 integrates USB Hub and Full-Speed functions in a single chip, enabling easy USB Hub application design with maintenance-free operation and proven USB compatibility.
- Application NotePDF 1.43 MB REJ05B1008-0110 Rev.1.10 Oct 04, 2006AI-generated Summary: The document provides guidelines and disclaimers for using Renesas 38K2 Group USB microcomputers, emphasizing that all information is subject to change and should be verified through official channels. It highlights restrictions on military and life-critical applications, advises adherence to product specifications, and recommends safety measures to prevent failures. The notes include examples for USB and Hub implementations and stress the importance of protective measures against communication failures caused by external noise.
- Application NoteAI-generated Summary: Ensure safety in circuit designs by considering potential semiconductor failures that may cause injury, fire, or damage. Use auxiliary circuits, non-flammable materials, and malfunction prevention. Product information may change without notice, and Renesas disclaims liability for damages from inaccuracies. Semiconductors are not for life-critical systems without prior approval. The document explains C language programming basics, project setup, compiler, assembler, linker, debugger, coding tips, stack estimation, and interrupt handling for the Renesas 740 family microcomputers.
- Application NoteAI-generated Summary: This document explains how to design PCB layouts to enhance noise immunity for the 740 family MCU, using the M37544G2ASP sample at 4 MHz on a single-sided board. It compares recommended and non-recommended layouts, highlighting five key design points: short oscillator wiring, close reset circuit placement, short CNVSS wiring with a resistor, decoupling capacitor placement near MCU, and unified VSS wiring. These principles reduce noise-induced failures and improve MCU stability.
- Application NoteAI-generated Summary: The programming guidelines for the 740 Family in C language have been updated and replaced by a new document titled "C Compiler Package for 740 Family M3T-ICC740 Application Notes" (Document No. REJ06J0005-0100). Users should refer to this new document for current information. Inquiries related to the previous guidelines should be sent via email to the provided contact.
- Application NoteAI-generated Summary: This document explains two methods for handling interrupts in the ICC-740 C Compiler for the 740 Family MCU. Method 1 involves modifying the interrupt vector table in the startup file and declaring interrupt functions with the 'interrupt' keyword. Method 2 deletes the interrupt vector table, reserves data space, and declares interrupt functions using the 'interrupt [offset]' syntax. Examples illustrate how to implement INTO interrupt handling in both methods.
