Overview
R5F10368DSP#V0 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for cost-sensitive consumer and industrial embedded control. It features 8 KB code flash, 512 B RAM, 1.8–5.5 V operation, 24 MHz max CPU speed (31 DMIPS), and integrated 10-bit A/D converter with 8 input channels - deployed in smart home sensors and battery-powered metering systems.
For engineers reviewing the R5F10368DSP#V0 datasheet, R5F10368DSP#V0 pinout, R5F10368DSP#V0 application, or R5F10368DSP#V0 equivalent, key selection considerations include its 20-pin LSSOP package, absence of data flash memory, single UART channel, no DMA controller, and ±5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C.
Technical Context
The R5F10368DSP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 0.04167 µs minimum instruction execution time at 24 MHz using the high-speed on-chip oscillator. It supports HALT, STOP, and SNOOZE low-power modes with 63 µA/MHz active current consumption.
Its peripheral set includes one 16-bit timer (TAU0) with 4 channels, one 12-bit interval timer, one window watchdog timer, simplified SPI (CSI) on one channel, and I²C-compatible interface (IICA0) - all configured via dedicated peripheral I/O redirection register (PIOR) for flexible pin assignment.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F10368DSP#V0?
The R5F10368DSP#V0 operates at up to 24 MHz using the high-speed on-chip oscillator, achieving 31 DMIPS performance. This is measured under HS mode with VDD ≥ 2.7 V; at lower supply voltages (1.8–2.4 V), max frequency drops to 16 MHz. The R5F10368DSP#V0's CISC architecture with 3-stage pipeline ensures consistent instruction throughput across voltage ranges.
Does the R5F10368DSP#V0 include data flash memory, and what are the implications for firmware updates?
No, the R5F10368DSP#V0 does not include data flash memory - unlike R5F102xx variants. This means runtime parameter storage or firmware update staging must use external EEPROM or FRAM. However, the R5F10368DSP#V0 retains full self-programming capability for its 8 KB code flash, enabling secure bootloader-based updates without external programming hardware.
How many analog input channels does the R5F10368DSP#V0 support, and what is their resolution and reference configuration?
The R5F10368DSP#V0 supports 8 analog input channels (ANI0–ANI3, ANI16–ANI22) with 10-bit resolution. It uses an internal 1.45 V reference voltage and supports differential measurement between AVREFP and AVREFM pins. The A/D converter operates across the full 1.8–5.5 V supply range, maintaining accuracy without external reference components.
What serial communication interfaces are integrated into the R5F10368DSP#V0, and how are they mapped to pins?
The R5F10368DSP#V0 integrates one UART channel (RxD0/TxD0), one simplified SPI (CSI) channel (SCK00/SI00/SO00), and one I²C-compatible interface (IICA0: SCLA0/SDAA0). These are multiplexed onto P10–P12, P11–P12, and P60–P61 respectively - with remapping possible via the Peripheral I/O Redirection Register (PIOR) to accommodate routing constraints in dense PCB layouts.
What low-power modes are supported by the R5F10368DSP#V0, and what typical current draw can be expected in each?
The R5F10368DSP#V0 supports HALT (1.2 µA), STOP (0.52 µA), and SNOOZE modes. In STOP mode with RTC and LVD enabled, current draw is 0.52 µA (typical); HALT mode draws 1.2 µA while retaining RAM and register contents. Active-mode current is 63 µA/MHz - verified at 24 MHz and 3.3 V. All modes retain wake-up capability via external interrupts or timer events.
