Product details
Overview
R5F1036AASP#X5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 MCU designed for cost-sensitive consumer applications requiring robust analog integration and deterministic real-time control. It features 2 KB code flash, 256 B RAM, 8-channel 10-bit ADC, single UART, and operates from 1.8 V to 5.5 V across –40°C to +85°C ambient. It delivers 31 DMIPS at 24 MHz and consumes just 63 μA/MHz in active mode - ideal for battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F1036AASP#X5 datasheet, R5F1036AASP#X5 pinout, R5F1036AASP#X5 application, or R5F1036AASP#X5 equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral limitations (no data flash, no DMA, no simplified I²C), and precise selection guidance against functionally aligned alternatives.
Technical Context
The R5F1036AASP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz). Its clock system integrates a high-speed on-chip oscillator (±5.0% accuracy over –40°C to +85°C) and supports external crystal up to 20 MHz via X1/X2 pins.
It includes a 16-bit timer array (TAU0) with 4 channels, one 12-bit interval timer, window watchdog timer, on-chip power-on-reset and voltage detector (12-level LVD), and key interrupt support for 6 inputs. All analog functions - including AVREFP/AVREFM reference pins and 8-channel ADC - are fully operational within its 20-pin LSSOP footprint.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F1036AASP#X5?
The R5F1036AASP#X5 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This rating is measured under standard conditions (VDD = 2.7–5.5 V, TA = –40°C to +85°C) and reflects actual integer instruction throughput - not theoretical peak. The R5F1036AASP#X5 maintains full peripheral functionality at this speed, including UART, ADC, and timer operations.
Does the R5F1036AASP#X5 include data flash memory, and what are the implications for firmware updates?
No, the R5F1036AASP#X5 does not include data flash memory - this is a defining distinction from the R5F102x series. Firmware updates must be performed exclusively via the 2 KB code flash using self-programming routines, with no dedicated non-volatile storage for configuration parameters or logs. Developers must allocate code flash space and manage erase/write cycles carefully, as each block erase affects executable code regions.
What are the supported serial communication interfaces on the R5F1036AASP#X5, and how many channels are available?
The R5F1036AASP#X5 supports exactly one UART channel (RxD0/TxD0) and one Simplified SPI (CSI) channel (SCK00/SI00/SO00). It does not include any I²C interface - simplified or standard - unlike some RL78/G12 variants. This limits direct connection to I²C sensors or EEPROMs without bit-banging or external bridge ICs, making it best suited for UART-based host communication and SPI-peripheral control.
What is the ADC configuration of the R5F1036AASP#X5, and which pins are dedicated to analog functions?
The R5F1036AASP#X5 integrates an 8-channel, 10-bit successive-approximation ADC with internal 1.45 V reference voltage. Dedicated analog pins include P20 (ANI0/AVREFP), P21 (ANI1/AVREFM), P22 (ANI2), P23 (ANI3), P10 (ANI16), P11 (ANI17), P12 (ANI18), and P14 (ANI20). These pins support both single-ended and pseudo-differential measurements, with AVREFP/AVREFM enabling ratiometric or absolute voltage measurement modes.
Is the R5F1036AASP#X5 pin-compatible with other RL78/G12 20-pin variants, and what are the key compatibility constraints?
The R5F1036AASP#X5 shares the same LSSOP-20 package and pinout with all RL78/G12 20-pin variants (e.g., R5F1026x, R5F1036x, R5F10368/69/67), but functional compatibility requires verification of peripheral enablement. Critical constraints include absence of data flash, DMA, and simplified I²C - meaning firmware written for R5F1026AASP#X5 will not run unmodified on R5F1036AASP#X5 due to missing peripheral registers and memory-mapped resources.
