Description
The R8C/33M Group is supported only for customers who have already adopted these products. The RL78/G1F Group is recommended for new designs
The R8C/33M Group of single-chip MCUs incorporates the R8C 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/33M Group has data flash (1KB × 4 blocks) with the background operation (BGO) function.

- Application NoteAI-generated Summary: The document explains the differences in flash memory functions between the R8C/36M Group and RL78/G14. It outlines the flash memory map and rewrite modes of the R8C/36M Group, including CPU rewrite mode, standard serial I/O mode, and parallel MO mode. The user ROM area is divided into blocks and can be rewritten using different methods, such as software commands from the CPU or external programmers. The boot ROM area stores the standard boot program for serial I/O rewriting.
- Application NoteAI-generated Summary: The document explains how to migrate from the R8C/36M Group's Timer RA to the RL78/G14's Timer RJ, covering five operational modes: timer mode, pulse output mode, event counter mode, pulse width measurement mode, and pulse period measurement mode. Timer RA is an 8-bit timer with an 8-bit prescaler, while Timer RJ is a 16-bit timer with a reload register and down counter. Both timers support equivalent functions, including counting internal or external pulses and measuring pulse width or period. The guide details hardware configurations, software descriptions, option byte settings, function specifications, and flow charts for each mode.Related Files:
- Application NoteAI-generated Summary: The document explains how to migrate the D/A converter functionality from the R8C/36M Group to the RL78/G14 family with 96-KB or larger flash memory. It compares the specifications, highlighting differences such as the reference voltage source (Vref pin for R8C/36M and Vpp pin for RL78/G14) and output pins. It also details register differences and recommends selecting normal mode on RL78/G14 to match R8C/36M operation. Related manuals and technical updates are referenced for further information.
- Application NoteAI-generated Summary: The document explains the migration method from the R8C/36M group to the RL78/G14 family focusing on power control via CPU clock operation modes. It summarizes power control modes in R8C/36M, including standard operating, wait, and stop modes, and compares them with RL78/G14 CPU clock modes such as normal operation, HALT, STOP, and SNOOZE. Key differences include the clock source selection after reset and the inability of RL78/G14 to use the low-speed on-chip oscillator as the CPU clock. Detailed mode transition diagrams and user manual references are provided.
- Application NoteAI-generated Summary: The document explains how to migrate the reset function from the R8C/36M group to the RL78/G14 family. It compares the reset types of both families, showing that RL78/G14 supports more reset types. It details the correspondence between reset functions and highlights differences in reset behavior, such as clock settings and protection states after reset. The guide also specifies conditions for hardware reset via the RESET pin for both groups, emphasizing timing and voltage requirements.
- Application NoteAI-generated Summary: This guide explains how to migrate I2C bus interface communication from the R8C/36M group to the RL78/G14 using the serial interface ICA. It compares operation modes, highlighting differences in transfer clock settings and communication formats. The RL78/G14 supports three modes including operation stop, I2C bus, and wakeup mode, while the R8C/36M supports EC bus and clock synchronous serial modes. Key differences include pin configurations, interrupt functions, and noise cancellation methods.
- Application NoteAI-generated Summary: The document explains how to migrate synchronous serial communication from the R8C/36M group's SSU to the RL78/G14's SAU. It details the operation modes of both units, showing that the R8C/36M's clock synchronous and 4-wire bus communication modes correspond to the RL78/G14's 3-wire serial I/O (CSI) mode. The chip select line functions differ slightly but are implemented via digital I/O ports or SSIOO pins on the RL78/G14. Sample code focuses on migrating the 4-wire bus mode.Related Files:
- Application NoteAI-generated Summary: The document details the migration process from the R8C/32C group A/D converter to the RL78/G11 A/D converter, explaining differences in operation modes and result storage. It highlights that RL78/G11 uses a single register for A/D results, unlike R8C/32C which uses multiple registers. It also explains the bit alignment differences in 10-bit and 8-bit resolutions, requiring software adjustments for compatibility. The guide covers various operation modes including one-shot, repeat, single sweep, and repeat sweep modes, with hardware and software descriptions, sample code, and reference materials.Related Files:

When using the D/A converter, can I stabilize the output voltage by adding a resistor for pull-down?
Since the D/A converter has an internal output resistor, if a pull-down resister is added, resistance from both the internal and pull-down resistors will divide the output level. Accordingly, D/A conversion precision will be worse than if there were no pull-down resistor. The ...
