Description
The R8C/38E, F, G, and H are limited to customers who have already adopted these products. The RL78/F12, F13, F14, F15 Groups are recommended for new designs.
The R8C/38E Group, R8C/38F Group, R8C/38G Group, and R8C/38H Group of single-chip MCUs incorporate the R8C/Tiny Series CPU core, employing sophisticated instructions for a high level of efficiency. With 1Mb of address space, and it is capable of executing instructions at high speed. In addition, the CPU core boasts a multiplier for high-speed operation processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs are designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of system components. The R8C/38E Group and R8C/38F Group have a single channel CAN module and are suitable for LAN systems in vehicles and for FA. The R8C/38G Group and the R8C/38H Group do not have CAN modules. The R8C/38E Group and the R8C/38G Group have data flash (1KB × 4 blocks) with the background operation (BGO) function.

- Application NoteAI-generated Summary: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.
- Application NotePDF 424 KB R01AN1648EJ0101 Rev.1.01 Mar 31, 2013AI-generated Summary: CAN communication requires initial settings including clock, bit timing, baud rate, and acceptance filters. Bit timing divides each bit into three segments: Synchronization Segment (SS), Time Segment 1 (TSEG1), and Time Segment 2 (TSEG2). TSEG1 and TSEG2 determine the sampling point and compensate for network delays and phase errors. The timing unit is time quanta (Tq), influenced by clock frequency and baud rate prescaler. Segment settings have specific ranges and restrictions to ensure proper synchronization and communication.
- Application NoteAI-generated Summary: The document presents performance data of the signal processing library on SH2A-FPU and RX devices, detailing CPU cycles for various DSP functions such as FFT, FIR, and IIR filters across different sample sizes and coefficients. It also provides Renesas Electronics website and support contact information. The revision record notes the first edition release date as December 17, 2010.Related Files:
- Application NotePDF 64 KB REG05B0076-0100 Rev.1.00 Jun 18, 2010AI-generated Summary: The source code projects for the R8C/38C Renesas Starter Kit provide examples of peripheral initialization, including a main C source file with a detailed comment block explaining functionality, such as ADC single operation mode triggered by software. The document outlines general precautions for handling MPU/MCU products, including unused pin handling, power-on processing, prohibition of reserved address access, clock signal stabilization, and product differences. It also provides Renesas website and inquiry links for support.Related Files:
- Application NotePDF 126 KB R20AN0090ES0100 Rev.1.00 Mar 01, 2010AI-generated Summary: The system timer in MR8C/4 tracks elapsed time in an RTOS by generating periodic interrupts, incrementing a tick counter. The timer's resolution depends on application needs, hardware limitations, and counter storage. MR8C/4 uses a 6-byte counter allowing up to 8925 years of tick counting at 1ms resolution. Hardware timer inaccuracies require adjustments to ensure minimum delay durations. Users configure the system timer by selecting hardware timers, setting interrupt priorities, and defining interrupt vectors. The system timer manages time-based functions and is optional if no time management is used.View More (87)
