Renesas R5F10369ASP#V0

Overview

R5F10369ASP#V0 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 MCU designed for cost-sensitive consumer applications. It features 12 KB code flash, 768 B RAM, 1.8–5.5 V operation, 24 MHz max CPU speed (31 DMIPS), and operates across –40°C to +85°C. It integrates an 8/10-bit 11-channel ADC, UART, simplified SPI (CSI), and key interrupt support - ideal for battery-powered sensor nodes and smart home peripherals.

For engineers reviewing the R5F10369ASP#V0 datasheet, R5F10369ASP#V0 pinout, R5F10369ASP#V0 application, or R5F10369ASP#V0 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional trade-offs - all grounded in Renesas' official R01DS0193EJ0250 Rev.2.50 specification.

Technical Context

The R5F10369ASP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz using its high-speed on-chip oscillator (±5.0% accuracy over –40°C to +85°C). It lacks data flash memory and DMA - distinguishing it from R5F102-series variants - and supports only one UART channel and one simplified SPI (CSI) channel.

Its 20-pin LSSOP package provides 18 I/O pins including two 6-V-tolerant N-ch open-drain outputs, four TTL-input-capable ports, and on-chip pull-up resistors. The device uses a dedicated low-speed on-chip oscillator (15 kHz) for watchdog timer operation and supports HALT, STOP, and SNOOZE low-power modes down to 63 μA/MHz.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F10369ASP#V0?

The R5F10369ASP#V0 achieves a maximum CPU clock frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This is measured under HS (high-speed main) mode with VDD ≥ 2.7 V and reflects integer instruction throughput per second - a key metric for real-time control loop execution in applications like motor commutation or sensor sampling.

Does the R5F10369ASP#V0 include data flash memory, and how does that affect firmware design?

No, the R5F10369ASP#V0 does not include data flash memory - unlike the R5F102-series counterparts. This means parameters such as calibration coefficients, user preferences, or event logs must be stored in code flash (with erase/write restrictions) or external EEPROM/FRAM. Firmware design must avoid frequent rewrites to code flash blocks and implement wear-leveling if using self-programming.

Which serial communication interfaces are available on the R5F10369ASP#V0, and are they pin-multiplexed?

The R5F10369ASP#V0 provides one UART channel (RxD0/TxD0), one simplified SPI (CSI00), and no native I²C interface. These functions are assigned to fixed pins: P11/P12 for UART, P10/P11/P12 for CSI00 clock/data lines, with overlap requiring sequential peripheral enablement. No software-configurable pin remapping is available for these primary serial functions.

What are the low-power modes supported by the R5F10369ASP#V0, and what is typical current draw in each?

The R5F10369ASP#V0 supports HALT (CPU stopped, peripherals active), STOP (all clocks halted except watchdog), and SNOOZE (selected peripherals active while CPU sleeps). Typical current in HALT mode is 0.52 mA at 24 MHz, STOP mode draws 0.23 μA, and SNOOZE mode consumes 1.8 μA - enabling sub-μA average system current when paired with periodic wake-up timers.

How many analog input channels and what ADC resolution does the R5F10369ASP#V0 provide?

The R5F10369ASP#V0 integrates an 8/10-bit successive-approximation ADC with 11 input channels (ANI0–ANI3, ANI16–ANI22). Resolution is selectable per conversion; 10-bit mode provides 1 mV LSB step size at 1.45 V reference, supporting precision thermistor or potentiometer readings in consumer HMI applications.
