Product details
Overview
R5F10368DSP#X5 from Renesas Electronics is a 20-pin, 8 KB flash, industrial-grade RL78/G12 16-bit microcontroller operating from 1.8 V to 5.5 V, delivering 31 DMIPS at 24 MHz with ultra-low power consumption (63 μA/MHz), used in battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F10368DSP#X5 datasheet, R5F10368DSP#X5 pinout, R5F10368DSP#X5 application, or R5F10368DSP#X5 equivalent, key selection criteria include its 8 KB code flash + no data flash configuration, -40°C to +85°C industrial temperature grade (D-suffix), LSSOP-20 package, and absence of DMA, CRC, and simplified I²C-distinguishing it from R5F102-series variants.
Technical Context
The R5F10368DSP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and selectable high-speed on-chip oscillator (1–24 MHz, ±5% accuracy over –40°C to +85°C). It supports HALT, STOP, and SNOOZE low-power modes for energy-constrained operation.
Peripheral integration includes one UART channel, one CSI channel, one I²C channel, four 16-bit timer channels (with PWM capability), an 8-channel 10-bit A/D converter, and 18 GPIO pins-including two 6-V-tolerant N-ch open-drain outputs-configured via fixed-function pin mapping without peripheral I/O redirection (PIOR = 00H).

FAQ
What is the maximum operating frequency and instruction throughput of the R5F10368DSP#X5?
The R5F10368DSP#X5 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. Its minimum instruction execution time is 0.04167 µs under this condition. The RL78 CPU core supports variable-speed operation down to 1 MHz (1 µs instruction time) for ultra-low-power modes, enabling dynamic voltage and frequency scaling in battery-powered designs.
Does the R5F10368DSP#X5 include data flash memory?
No, the R5F10368DSP#X5 does not include data flash memory. As confirmed in the RL78/G12 datasheet section 1.3.1, R5F103-series devices-including R5F10368DSP#X5-have no mounted data flash, unlike R5F102-series parts. This simplifies firmware update architecture and reduces cost, making it ideal for applications where parameter storage is handled externally or via code flash emulation.
What package type and pin count does the R5F10368DSP#X5 use?
The R5F10368DSP#X5 uses a 20-pin plastic LSSOP package (4.4 × 6.5 mm, 0.65 mm pitch), indicated by the "SP" suffix and "6" digit in the part number (R5F10368DSP#X5 → "6" = 20-pin). This surface-mount package supports automated assembly and provides 18 usable I/O pins, including analog inputs, UART, I²C, and timer resources, in a compact footprint.
What are the key differences between R5F10368DSP#X5 and R5F10268DSP#X5?
The R5F10368DSP#X5 omits data flash (2 KB), DMA controller, CRC engine, RAM guard, and simplified I²C compared to R5F10268DSP#X5. It also has reduced high-speed oscillator accuracy (±5% vs. ±1%) and fewer serial interface channels. These trade-offs reduce cost and complexity while maintaining identical 8 KB flash, 20-pin LSSOP packaging, and industrial temperature rating-making R5F10368DSP#X5 optimal for cost-driven, non-data-logging applications.
Which development tools support the R5F10368DSP#X5?
The R5F10368DSP#X5 is supported by Renesas' E2 studio IDE, CS+ (formerly CubeSuite+), and the Renesas Flash Programmer. Hardware debugging requires the E2 emulator Lite or E2 emulator, both compatible with the on-chip debug interface exposed via TOOL0, TOOLRxD, and TOOLTxD pins. The device's LSSOP-20 package is supported by Renesas' RTK0EM0002D00001BJ evaluation board for rapid prototyping and validation.
