Description
The R8C/14 Group is supported only for customers who have already adopted these products. The RL78/G12 Group is recommended for new designs.
This MCU is built using the high-performance silicon gate CMOS process using a R8C/Tiny Series CPU core and is packaged in a 32-pin plastic molded LQFP. This MCU operates using sophisticated instructions featuring a high level of instruction efficiency. With 1Mb of address space, it is capable of executing instructions at high speed. The data flash ROM (2KB X 2 blocks) is embedded.

- 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 NoteAI-generated Summary: The document specifies the serial communication protocols for the R8C/1x and 2x Series microcontrollers in standard serial I/O modes 2 and 3. It details boot program operations including initial settings, communication with a serial programmer, and control commands for flash memory. Communication formats are asynchronous, with defined data transfer structures. Pin assignments and connection examples for both modes are provided. Initial settings cover selecting communication mode based on the MODE pin level after reset and adjusting the bit rate to 9600 bps through a defined handshake process with the serial programmer.

- 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 NoteAI-generated Summary: This document explains how to configure and operate the asynchronous serial interface mode (UART) for data reception at 9600bps using the R32C/100 Series MCUs. It details setting bit rates, data format (8-bit length, odd parity, 1 stop bit), and internal clock usage. RTS pins control data reception flow, with specific port and register settings provided. The reception process includes RTS signaling, bit order, and interrupt handling upon data receipt.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 (103)
