- Application NoteAI-generated Summary: The document explains serial I/O connections for the 3850A Group MCU. It details examples of connecting peripheral ICs with CS pins in clock synchronous serial I/O mode, including transmission only, transmission and reception, and multiple IC connections. It also describes serial I/O connections between MCUs, showing internal and external clock selection and UART mode usage. Specific pin assignments for serial I/O1 and serial I/O2 are provided, along with notes on output control and signal behavior.
- Application NoteAI-generated Summary: The 3850A Group MCU's A/D converter operates by clearing the conversion completion bit and starting conversion with the buffer register set to zero. It compares the analog input voltage with a reference voltage bit by bit, updating the buffer register accordingly. Conversion completes in 61 cycles for high and middle speeds or 40 microseconds in low-speed mode, storing results in specific registers and triggering an interrupt. The document includes timing charts and circuit diagrams illustrating this process.
- Application NoteAI-generated Summary: The document explains how to use the Key Scan function on the 3850A Group MCU with a 4x4 key matrix input. It details the scan output and key input ports, scanning intervals, and key input conditions, including disabling input when two keys are pressed simultaneously. It provides connection diagrams, RAM and flag definitions, register settings, and control procedures necessary for implementation.Related Files:
- Technical Update
- 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.View More (14)

(3850A) How do you enable protection in the QzROM version?
For QzROM programming using a programmer, set protection using the programmer. For the setting method, please refer to the programmer manual. For products programmed and shipped by Renesas, set protection in the ROM options in the mask file converter (MM). Please note enable/disable of the ROM code protect ...
Jun 6, 2007 -
(3850A) In the QzROM, can additional programs be written to the free area in ROM?
As long as protect is not enabled, it is possible to write to the ROM. However, be careful not to "overwrite" bits that have already been written to. (#106722)
Jun 6, 2007 -
(3850A) What values of external capacitance can be added to the ports?
(1) CMOS3 State I/O Ports When adding external capacitance, select 100pF or less. (2) Input-only Ports There are no special restrictions on these ports. Select the capacitance according to the characteristics of the externally connected circuit. (#104751)
