Product details
Overview
R5F1036AASP#X0 from Renesas Electronics is a 20-pin LSSOP RL78/G12 16-bit microcontroller designed for ultra-low-power general-purpose embedded control. It features 16 KB code flash, 1 KB RAM, 10-bit A/D converter (11 channels), 4-channel 16-bit timer, UART, and operates from 1.8 V to 5.5 V at –40°C to +85°C - deployed in battery-powered sensor nodes and smart home controllers.
For engineers reviewing the R5F1036AASP#X0 datasheet, R5F1036AASP#X0 pinout, R5F1036AASP#X0 application, or R5F1036AASP#X0 equivalent, key selection criteria 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 full temperature range.
Technical Context
The R5F1036AASP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting minimum instruction execution time of 0.04167 µs at 24 MHz using the high-speed on-chip oscillator. Its clock system integrates selectable high-speed (1–24 MHz) and low-speed (15 kHz) on-chip oscillators, plus external crystal support (1–20 MHz via X1/X2).
Peripheral integration includes one UART channel, one simplified SPI (CSI) channel, no simplified I²C, 4-channel TAU0 timer with PWM capability, 11-channel 10-bit A/D converter with internal reference (1.45 V), and key interrupt support across six pins - all optimized for deterministic real-time control in resource-constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables efficient code density and deterministic timing for control loops. |
| Operating Voltage | 1.8 V to 5.5 V; supports direct interface with Li-ion, coin-cell, and industrial 3.3/5 V rails without level-shifting. |
| Flash / RAM | 16 KB code flash + 1 KB RAM; sufficient for firmware with communication stacks and sensor fusion logic. |
| A/D Converter | 10-bit resolution, 11 input channels, internal 1.45 V reference; enables multi-sensor analog monitoring without external references. |
| Timers | 4-channel 16-bit TAU0 + 12-bit interval timer + watchdog; provides precise PWM generation, periodic interrupts, and safety supervision. |
| Serial Interfaces | 1 × UART, 1 × CSI (SPI-compatible), 0 × I²C; suitable for point-to-point serial telemetry or simple peripheral bridging. |
| Power Modes | HALT, STOP, SNOOZE; achieves 63 μA/MHz active current and sub-μA standby - critical for >5-year battery life. |
Pinout & Package
Package: 20-pin plastic LSSOP (4.4 × 6.5 mm, 0.65-mm pitch), JEDEC standard PLSP0020JB-A footprint.

FAQ
What is the maximum operating frequency of the R5F1036AASP#X0?
The R5F1036AASP#X0 supports a maximum high-speed on-chip oscillator frequency of 24 MHz, enabling a peak performance of 31 DMIPS. External crystal operation is rated up to 20 MHz. The actual achievable frequency depends on VDD voltage: 24 MHz requires VDD ≥ 2.7 V, while 16 MHz is supported down to VDD = 2.4 V, and 8 MHz operation is guaranteed from 1.8 V.
Does the R5F1036AASP#X0 include data flash memory?
No, the R5F1036AASP#X0 does not include data flash memory. This distinguishes it from the R5F102x series (e.g., R5F1026AASP#X0), which integrates 2 KB of data flash. The R5F1036AASP#X0 relies solely on its 16 KB code flash for program storage and uses RAM for runtime variables - appropriate for applications where non-volatile parameter storage is handled externally or omitted entirely.
What are the key differences between R5F1036AASP#X0 and R5F1026AASP#X0?
The R5F1036AASP#X0 omits data flash memory and the DMA controller present in the R5F1026AASP#X0, and features ±5.0% high-speed on-chip oscillator accuracy (vs. ±1.0% in R5F1026AASP#X0). Both share identical 16 KB code flash, 1 KB RAM, 20-pin LSSOP package, and core peripheral set - making R5F1036AASP#X0 a lower-cost option where those features are unnecessary.
Which serial interfaces are supported by the R5F1036AASP#X0?
The R5F1036AASP#X0 supports one UART channel (RxD0/TxD0), one simplified SPI (CSI) channel (SCK00/SI00/SO00), and zero simplified I²C channels. It does not implement simplified I²C or standard I²C hardware - unlike some 30-pin RL78/G12 variants. This configuration suits point-to-point serial communication and basic peripheral interfacing without multi-master bus complexity.
What is the A/D converter specification for the R5F1036AASP#X0?
The R5F1036AASP#X0 integrates an 11-channel, 10-bit successive-approximation A/D converter with internal 1.45 V reference voltage and temperature sensor. Input channels include ANI0–ANI3 and ANI16–ANI22. Full-scale range is VDD-referenced, and conversion time is 14–20 μs depending on clock source - enabling accurate analog monitoring for environmental and power-supply sensing in low-power systems.
