Product details
Overview
R5F10369DSP#35 from Renesas Electronics is a 20-pin LSSOP RL78/G12 16-bit microcontroller with 8 KB code flash, 768 B RAM, and 1.8–5.5 V operation. It delivers 31 DMIPS at 24 MHz, features an ultra-low-power HALT/STOP/SNOOZE mode (63 μA/MHz), and integrates 8-channel 10-bit ADC, UART, CSI, and watchdog timer for embedded control in battery-powered industrial sensors.
For engineers reviewing the R5F10369DSP#35 datasheet, R5F10369DSP#35 pinout, R5F10369DSP#35 application, or R5F10369DSP#35 equivalent, key selection criteria include its 20-pin LSSOP package, absence of data flash memory, -40°C to +85°C industrial temperature grade (D suffix), and single UART + single CSI peripheral configuration versus higher-pin variants.
Technical Context
The R5F10369DSP#35 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution time of 0.04167 μs at 24 MHz using the high-speed on-chip oscillator. Its memory map spans 1 MB address space with 8 KB code flash organized in 1 KB blocks and no data flash - distinguishing it from R5F102-series parts.
Peripheral integration includes one UART channel, one simplified SPI (CSI) channel, no simplified I²C, four 16-bit timer channels, and an 8-channel 10-bit A/D converter with internal 1.45 V reference. It lacks DMA, CRC, RAM guard, and SFR guard functions present in R5F102 counterparts, confirming its cost-optimized role in basic control applications.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F10369DSP#35?
The R5F10369DSP#35 operates at up to 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 these conditions. The device also supports lower-frequency modes (1–16 MHz) for reduced power consumption in battery-operated applications, with guaranteed operation across the full 1.8–5.5 V supply range.
Does the R5F10369DSP#35 include data flash memory, and how does that affect firmware updates?
No, the R5F10369DSP#35 does not include data flash memory - this is a key distinction from the R5F102-series parts. Firmware updates must be performed using the 8 KB code flash memory only, with self-programming enabled via the flash shield window function. Applications requiring persistent parameter storage or background data logging will need external EEPROM or FRAM, as no on-chip non-volatile data memory is available in the R5F10369DSP#35.
What serial communication interfaces are supported by the R5F10369DSP#35, and how are they allocated on the 20-pin package?
The R5F10369DSP#35 supports one UART channel and one simplified SPI (CSI) channel - no simplified I²C is included. On the 20-pin LSSOP package, UART0 uses P11 (RxD0) and P12 (TxD0), while CSI00 uses P10 (SCK00), P11 (SI00), and P12 (SO00). These functions can be remapped to alternate pins (e.g., P60/P61 for UART) using the Peripheral I/O Redirection Register (PIOR), enabling flexible PCB routing without changing the R5F10369DSP#35 footprint.
What is the ADC configuration of the R5F10369DSP#35, and what reference voltage options are available?
The R5F10369DSP#35 integrates an 8-channel, 10-bit successive-approximation ADC with internal 1.45 V reference voltage and support for external references via AVREFP/AVREFM pins. It operates across the full 1.8–5.5 V supply range and includes a temperature sensor. The ADC can perform single or continuous conversions with software or timer-triggered start, making it suitable for monitoring battery voltage, thermistors, and current-sense amplifiers in industrial control applications.
How does the power management capability of the R5F10369DSP#35 support battery-powered applications?
The R5F10369DSP#35 supports HALT, STOP, and SNOOZE low-power modes with typical active current consumption of 63 μA/MHz. In STOP mode, current drops to 0.52 μA (typical) with RAM retention, while SNOOZE mode enables peripheral operation (e.g., UART receive) with CPU halted - ideal for intermittent sensor polling. Combined with its 1.8 V minimum operating voltage, this allows direct use with single-cell Li-ion or alkaline batteries, extending operational life in portable and remote monitoring devices.
