Product details
Overview
R5F1036AASP#V0 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for cost-sensitive consumer applications. It features 2 KB code flash, 256 B RAM, 1.8–5.5 V operation, 24 MHz max CPU speed (31 DMIPS), and an 8/10-bit 11-channel ADC - deployed in battery-powered remote controls and smart home sensors.
For engineers reviewing the R5F1036AASP#V0 datasheet, R5F1036AASP#V0 pinout, R5F1036AASP#V0 application, or R5F1036AASP#V0 equivalent, key selection criteria include its 20-pin LSSOP package, absence of data flash memory, single UART channel, no DMA support, and ±5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C.
Technical Context
The R5F1036AASP#V0 implements the RL78 CPU core with a 3-stage CISC pipeline, 1 MB address space, and configurable instruction execution time (0.04167 µs at 24 MHz). It operates in HALT, STOP, and SNOOZE low-power modes, achieving 63 µA/MHz active current consumption.
It integrates a 12-bit interval timer, window watchdog timer, on-chip power-on-reset and voltage detector (12-level LVD), and supports external crystal (1–20 MHz) or internal high-speed oscillator (1–24 MHz) clock sources - all within a single 1.8–5.5 V supply rail.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1026AASP#V0 | Includes 2 KB data flash, ±1.0% oscillator accuracy, DMA, CRC, and RAM guard | Required for firmware-over-the-air updates or runtime parameter storage | Select when field-upgradable code or secure data logging is mandatory |

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F1036AASP#V0?
The R5F1036AASP#V0 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. This is measured under HS (high-speed main) mode with VDD ≥ 2.7 V. The minimum instruction execution time is 0.04167 µs, enabling responsive real-time control in battery-constrained applications.
Does the R5F1036AASP#V0 include data flash memory?
No, the R5F1036AASP#V0 does not include data flash memory. As confirmed in the RL78/G12 datasheet Section 1.3.1, data flash (2 KB) is present only in R5F102x products; R5F103x variants like the R5F1036AASP#V0 omit this feature to reduce cost and die size while retaining full code flash functionality.
What are the key differences between the R5F1036AASP#V0 and R5F1026AASP#V0?
The R5F1036AASP#V0 lacks data flash memory, DMA controller, CRC engine, RAM guard, and SFR guard - features present in the R5F1026AASP#V0. Its high-speed on-chip oscillator accuracy is ±5.0% (vs. ±1.0% for R5F1026AASP#V0), and it supports fewer serial interface channels (1 UART + 1 CSI vs. 1 UART + 2 CSI + 2 I²C).
Which package type and footprint does the R5F1036AASP#V0 use?
The R5F1036AASP#V0 uses a 20-pin plastic LSSOP package (4.4 × 6.5 mm, 0.65-mm pitch) with JEDEC-standard PLSP0020JB-A footprint. It is supplied in tray packaging (#V0 designation), compatible with automated SMT assembly and reflow profiles for lead-free processes.
Can the R5F1036AASP#V0 operate from a single 1.8 V supply?
Yes, the R5F1036AASP#V0 supports full operation across 1.8 V to 5.5 V, including all peripherals and the 24 MHz high-speed on-chip oscillator (in LS mode). At 1.8 V, it delivers reliable performance for low-power sensor acquisition and wake-on-interrupt functions - verified per datasheet Section 1.1 and Electrical Specifications Table 2.1.
