Product details
Overview
R5F1036AASM#35 from Renesas Electronics is a 20-pin RL78/G12 16-bit microcontroller with 16 KB code flash, 1 KB RAM, and no data flash memory, operating at 1.8–5.5 V. It features a 24 MHz high-speed on-chip oscillator (±5% accuracy), 10-bit 11-channel ADC, 4-channel 16-bit timer, UART, CSI, and key interrupt support - deployed in battery-powered consumer appliances requiring ultra-low power (63 μA/MHz) and compact TSSOP packaging.
For engineers reviewing the R5F1036AASM#35 datasheet, R5F1036AASM#35 pinout, R5F1036AASM#35 application, or R5F1036AASM#35 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases for low-voltage embedded control, and two confirmed alternative parts with documented functional and peripheral differences.
Technical Context
The R5F1036AASM#35 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz. Its memory map spans 1 MB address space, with 16 KB code flash organized in 1 KB blocks and 1 KB SRAM - no data flash or DMA controller, distinguishing it from R5F102x variants.
It supports HALT/STOP/SNOOZE low-power modes, uses a dedicated 15 kHz low-speed on-chip oscillator for watchdog timing, and provides programmable clock/buzzer output via PCLBUZ0. Peripheral I/O redirection enables flexible pin assignment for UART0, CSI00, and analog inputs ANI0–ANI3/ANI16–ANI22.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1026AASM#35 | Includes 2 KB data flash and DMA controller; ±1% oscillator accuracy; CRC and RAM/SFR guard features | Required for field firmware updates or safety-certified designs needing memory protection | Select when data logging, secure boot, or functional safety compliance (IEC 61508) is required |
| R5F1036ADSP#V5 | Same core and peripherals but rated for industrial TA = –40°C to +85°C; packaged in LSSOP20 instead of TSSOP20 | Suitable for factory automation where extended temperature stability is mandatory | Choose for industrial environments where thermal cycling exceeds consumer-grade specs |
Compared with R5F1026AASM#35, the R5F1036AASM#35 omits data flash and safety peripherals to reduce cost and power - making it optimal for cost-sensitive, non-updatable consumer devices; versus R5F1036ADSP#V5, its TSSOP20 package offers better thermal dissipation and PCB assembly compatibility in space-constrained layouts.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F1036AASM#35?
The R5F1036AASM#35 integrates a high-speed on-chip oscillator configurable up to 24 MHz, with ±5.0% frequency accuracy over the full operating temperature range of –40°C to +85°C. This specification is confirmed in Section 1.3.2(2) of the R01DS0193EJ0250 datasheet. For applications requiring tighter timing, an external crystal (X1/X2) or EXCLK input must be used - the R5F1036AASM#35 supports up to 20 MHz crystal operation in HS mode.
Does R5F1036AASM#35 include data flash memory?
No, the R5F1036AASM#35 does not include data flash memory. As explicitly stated in Section 1.3.1 of the datasheet, R5F103 products (including R5F1036AASM#35) have "Not mounted" data flash, whereas R5F102 products provide 2 KB. This absence means firmware cannot perform in-field parameter storage or over-the-air updates without external EEPROM or Flash - a key differentiator from R5F1026AASM#35.
How many analog input channels does R5F1036AASM#35 support, and what is the reference voltage?
The R5F1036AASM#35 supports 11 analog input channels (ANI0–ANI3 and ANI16–ANI22) with 10-bit resolution. It includes an internal reference voltage of 1.45 V (typical), as specified in Section 1.1 Features and Table 1-1. This reference is used by default unless AVREFP/AVREFM pins are externally biased - enabling accurate sensor readings without external voltage references in most consumer applications.
What low-power modes are available on R5F1036AASM#35, and what are their typical current draws?
The R5F1036AASM#35 supports HALT, STOP, and SNOOZE low-power modes. While exact current values depend on configuration and VDD, the platform achieves 63 μA/MHz in active mode and sub-μA currents in STOP mode - per Section 1.1 Features. SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate while CPU sleeps, enabling responsive wake-up from sensor interrupts with minimal energy penalty.
Is R5F1036AASM#35 pin-compatible with other RL78/G12 20-pin variants like R5F1026AASM#35?
Yes, the R5F1036AASM#35 shares identical pinout and package (20-pin TSSOP, PTSP0020JI-A) with R5F1026AASM#35 and other RL78/G12 20-pin members. However, functional differences exist: R5F1036AASM#35 lacks data flash, DMA, CRC, and RAM/SFR guard features present in R5F1026AASM#35. Pin compatibility enables hardware reuse, but firmware must account for missing peripherals and oscillator accuracy variance (±5% vs. ±1%).
