Renesas R5F10367DSP#V0

Overview

R5F10367DSP#V0 from Renesas Electronics is a 20-pin LSSOP RL78/G12 16-bit microcontroller designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It integrates 2 KB code flash, 256 B RAM, 10-bit A/D converter with 8 input channels, 4-channel 16-bit timer, and single UART interface - enabling compact sensor node and battery-powered appliance control.

For engineers reviewing the R5F10367DSP#V0 datasheet, R5F10367DSP#V0 pinout, R5F10367DSP#V0 application, or R5F10367DSP#V0 equivalent, key selection criteria include its 1.8–5.5 V operation range, absence of data flash memory, lack of DMA and safety functions (CRC/SFR guard), and simplified peripheral set optimized for cost-sensitive, low-complexity control tasks.

Technical Context

The R5F10367DSP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, delivering 31 DMIPS at 24 MHz while consuming only 63 μA/MHz. Its clock system combines a high-speed on-chip oscillator (1–24 MHz, ±5% accuracy over –40°C to +85°C) and low-speed 15 kHz on-chip oscillator, supporting HALT, STOP, and SNOOZE power modes.

It features 18 I/O pins including two 6-V-tolerant N-ch open-drain outputs, programmable key interrupt support, and analog inputs with internal 1.45 V reference and temperature sensor. Peripheral integration excludes data flash, DMA, simplified I²C, and simplified SPI - distinguishing it from R5F102-series counterparts.

FAQ

What is the maximum operating frequency and power consumption of the R5F10367DSP#V0?

The R5F10367DSP#V0 operates up to 24 MHz using its high-speed on-chip oscillator and achieves 31 DMIPS performance. Its active-mode current is specified at 63 μA/MHz, resulting in approximately 1.5 mA total at 24 MHz - enabling extended battery life in portable applications. The device supports HALT, STOP, and SNOOZE low-power modes to further reduce consumption during idle periods.

Does the R5F10367DSP#V0 include data flash memory?

No, the R5F10367DSP#V0 does not include data flash memory. Unlike the R5F102-series variants, all R5F103 products - including R5F10367DSP#V0 - omit the 2 KB data flash module. This means non-volatile parameter storage must be implemented externally (e.g., via I²C EEPROM) or in reserved code flash sectors with careful wear-leveling management.

What are the key differences between R5F10367DSP#V0 and R5F10267DSP#V0?

The R5F10367DSP#V0 lacks data flash, DMA controller, CRC calculation unit, SFR guard, and RAM guard functions present in the R5F10267DSP#V0. Its high-speed on-chip oscillator accuracy is ±5% (vs. ±1% for R5F10267DSP#V0), and it omits simplified SPI and simplified I²C interfaces. These omissions reduce cost and complexity while maintaining core control functionality for less demanding applications.

Which development tools support the R5F10367DSP#V0?

The R5F10367DSP#V0 is fully supported by Renesas' CS+ IDE, e² studio (with GCC RL78 toolchain), and the Renesas Flash Programmer. Hardware debugging uses the on-chip debug interface via standard 6-pin E1/E20 emulators. No external debug probe is required - the R5F10367DSP#V0's integrated debug circuit enables full breakpoint, watchpoint, and memory inspection capabilities out-of-the-box.

Can the R5F10367DSP#V0 operate from a 1.8 V supply with full peripheral functionality?

Yes, the R5F10367DSP#V0 guarantees full operation - including 10-bit A/D conversion, UART communication, timer functions, and I/O drive - across its entire 1.8–5.5 V supply range. At 1.8 V, the maximum allowed main system clock is 8 MHz (LS mode), and the high-speed on-chip oscillator operates down to 1 MHz, ensuring reliable low-voltage functionality for energy-harvesting and primary battery applications.
