Product details
Overview
R5F1036AASP#V5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for cost-sensitive consumer applications. It features 16 KB code flash, 256 B RAM, 10-bit A/D converter with 11 input channels, 4-channel 16-bit timer (TAU0), and UART/CSI serial interfaces - all operating across 1.8–5.5 V supply and –40°C to +85°C ambient temperature.
For engineers reviewing the R5F1036AASP#V5 datasheet, R5F1036AASP#V5 pinout, R5F1036AASP#V5 application, or R5F1036AASP#V5 equivalent, key selection considerations include its absence of data flash memory, lack of DMA controller, simplified I²C omission, and ±5.0% high-speed on-chip oscillator accuracy - distinguishing it from R5F102-series variants in power-constrained sensor nodes, appliance controls, and battery-powered HMI interfaces.
Technical Context
The R5F1036AASP#V5 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz while consuming only 63 μA/MHz in active mode. Its clock system integrates a high-speed on-chip oscillator (selectable 1–24 MHz) with ±5.0% accuracy over –40°C to +85°C, plus a dedicated 15 kHz low-speed on-chip oscillator for watchdog and interval timing.
Peripheral integration includes one UART channel, one CSI (Simplified SPI) channel, 11-channel 10-bit A/D converter with internal reference (1.45 V) and temperature sensor, and four 16-bit timer output channels supporting PWM generation. It omits data flash, DMA, CRC, RAM/SFR guard, and simplified I²C - confirming its role as a streamlined variant within the RL78/G12 family for deterministic real-time control without background data logging.

FAQ
What is the maximum operating frequency of the R5F1036AASP#V5?
The R5F1036AASP#V5 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. This yields 31 DMIPS performance while maintaining 63 μA/MHz active current efficiency. External crystal operation is limited to 20 MHz in HS mode (VDD ≥ 2.7 V) or 8 MHz in LS mode (VDD ≥ 1.8 V), as specified in the electrical characteristics table.
Does the R5F1036AASP#V5 include data flash memory?
No, the R5F1036AASP#V5 does not include data flash memory. Per Renesas documentation, data flash (2 KB) is present only in R5F102-series devices; the R5F1036AASP#V5 belongs to the R5F103 product line, which omits this feature entirely. Firmware must use code flash for parameter storage with appropriate wear-leveling, or external EEPROM/Flash.
What serial communication interfaces are available on the R5F1036AASP#V5?
The R5F1036AASP#V5 provides one UART channel (RxD0/TxD0), one CSI (Simplified SPI) channel (SCK00/SI00/SO00), and no I²C interface. While pins P60/P61 are labeled SCLA0/SDAA0, Renesas explicitly states these functions are inactive in R5F103 products. The device supports UART-based host communication and SPI-connected peripherals like ADCs or displays.
What is the A/D converter specification for the R5F1036AASP#V5?
The R5F1036AASP#V5 integrates an 11-channel, 10-bit successive-approximation A/D converter with internal 1.45 V reference voltage and integrated temperature sensor. Input channels include ANI0–ANI3 and ANI16–ANI22. Conversion time is 1.1 μs per sample at 24 MHz system clock, and the module supports both single-shot and continuous scan modes.
Is the R5F1036AASP#V5 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F1036AASP#V5 shares identical 20-pin LSSOP pinout and package dimensions (PLSP0020JB-A) with other R5F1026x and R5F1036x devices. Pin functions match across the family, though some alternate functions (e.g., I²C, DMA, data flash control) are disabled in R5F1036AASP#V5. This enables drop-in replacement where peripheral requirements align.
