Product details
Overview
R5F1036AASP#35 from Renesas Electronics is a 20-pin LSSOP RL78/G12 16-bit microcontroller designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It integrates 16 KB code flash, 256 B RAM, 10-bit A/D converter with 11 input channels, and operates from 1.8 V to 5.5 V with 63 μA/MHz active current. It delivers 31 DMIPS at 24 MHz and supports UART, CSI, and on-chip debug - ideal for battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F1036AASP#35 datasheet, R5F1036AASP#35 pinout, R5F1036AASP#35 application, or R5F1036AASP#35 equivalent, this page provides verified technical context, package mapping, functional alternatives, and supply-chain support specific to the R5F1036AASP#35 - not generic RL78/G12 family data.
Technical Context
The R5F1036AASP#35 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and selectable instruction execution time (0.04167 µs @ 24 MHz high-speed on-chip oscillator). It lacks data flash memory and DMA controller - distinguishing it from R5F1026x variants - and uses a simplified SPI (CSI) interface instead of full I²C or multiple UART channels.
Its peripheral set includes one UART channel, one CSI channel, four 16-bit timer channels, a 12-bit interval timer, watchdog timer, and key interrupt support across six pins. The device relies on external crystal (X1/X2) or internal oscillator (1–24 MHz ±5% accuracy over –40°C to +85°C) and supports HALT/STOP/SNOOZE low-power modes without data flash background operation.

FAQ
What is the maximum operating frequency of the R5F1036AASP#35?
The R5F1036AASP#35 supports up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. When using an external crystal (X1/X2), the maximum frequency is 20 MHz in HS mode (VDD ≥ 2.7 V) or 16 MHz (VDD ≥ 2.4 V). The device does not support frequencies beyond these limits under specified voltage and temperature conditions.
Does the R5F1036AASP#35 include data flash memory?
No, the R5F1036AASP#35 does not include data flash memory. This is a defining distinction from the R5F1026x series. All non-volatile data storage must be implemented externally or within the 16 KB code flash using self-programming routines - which require careful RAM allocation and erase-block management per Renesas Application Note R01AN3823.
What serial communication interfaces are supported by the R5F1036AASP#35?
The R5F1036AASP#35 supports one UART channel (UART0), one Simplified SPI (CSI0), and no I²C interface. While pin functions like SCLA0 and SDAA0 appear in the pinout, they are not functional in the R5F1036x variant per Renesas documentation - only the R5F1026x series implements I²C hardware.
Can the R5F1036AASP#35 operate from a 1.8 V supply?
Yes, the R5F1036AASP#35 is fully specified for operation from 1.8 V to 5.5 V. At 1.8 V, it supports up to 8 MHz in LS (low-speed main) mode and retains full functionality including 10-bit A/D conversion, timers, and UART - enabling direct use with single-cell lithium or two alkaline batteries without voltage regulation.
What is the oscillator accuracy specification for the R5F1036AASP#35?
The high-speed on-chip oscillator of the R5F1036AASP#35 has ±5.0% accuracy over the full operating temperature range of –40°C to +85°C. This is less precise than the ±1.0% accuracy offered by the R5F1026x series, making the R5F1036AASP#35 suitable for applications where absolute timing precision is secondary to power efficiency and cost.
