Product details
Overview
R5F100AAASP#X0 from Renesas is a 30-pin, LSSOP-packaged RL78/G13 16-bit microcontroller with 16 KB flash memory, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), UART, I²C, SPI, RTC, and watchdog timer - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F100AAASP#X0 datasheet, R5F100AAASP#X0 pinout, R5F100AAASP#X0 application, or R5F100AAASP#X0 equivalent, key selection criteria include its 30-pin LSSOP-30 package, 16 KB code flash with self-programming capability, 10-bit ADC input count, real-time clock calendar function, and support for STOP/HALT/SNOOZE low-power states in resource-constrained embedded designs.
Technical Context
The R5F100AAASP#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates on-chip peripherals including a 12-bit interval timer, 16-bit timer array (8 channels), real-time clock with calendar/alarm/correction, and DMA controller (2 channels) supporting 2-clock transfers between SFR and RAM - all optimized for deterministic timing in motor control and metering applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100BAANA#U0 | 32-pin HWQFN package, 16 KB flash, 2 KB RAM, same RL78/G13 core but higher pin count and QFN thermal performance | Preferred where PCB space permits smaller footprint and improved thermal dissipation in motor driver heatsink proximity | Select when layout allows 5×5 mm QFN and thermal management is critical; not pin-compatible with R5F100AAASP#X0 |
| R5F101AAASP#X0 | Same 30-pin LSSOP package and memory (16 KB/2 KB), but lacks data flash - no BGO or flash shield window functionality | Suitable for cost-sensitive applications where parameter storage is handled externally or via EEPROM | Choose when data flash is unnecessary and BOM cost reduction is prioritized over field-upgradable configuration storage |
Compared with R5F100BAANA#U0, R5F100AAASP#X0 offers lower assembly cost and simpler reflow in LSSOP but less thermal headroom; versus R5F101AAASP#X0, it adds 4 KB data flash with BGO - enabling robust runtime parameter persistence without interrupting application execution.

FAQ
What is the maximum operating frequency of the R5F100AAASP#X0?
The R5F100AAASP#X0 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. This frequency is fully supported across the full 1.6 V to 5.5 V supply range and -40°C to +85°C ambient temperature, with oscillator accuracy of ±1.0% under those conditions.
Does the R5F100AAASP#X0 include a real-time clock with calendar functionality?
Yes, the R5F100AAASP#X0 integrates a dedicated real-time clock (RTC) module supporting full calendar operation for 99 years, alarm interrupts, and clock correction - all functional in STOP mode with only 0.57 μA current draw, making it ideal for time-critical logging and scheduling.
How much data flash memory does the R5F100AAASP#X0 provide, and what are its key features?
The R5F100AAASP#X0 includes 4 KB of data flash memory rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for non-disruptive firmware parameter updates.
What analog peripherals are integrated into the R5F100AAASP#X0?
The R5F100AAASP#X0 integrates a 10-bit successive-approximation ADC with 6 analog input channels (ANI0–ANI2, ANI18, plus two more mapped to other pins), internal 1.45 V reference voltage, and temperature sensor - all operable across the full 1.6–5.5 V supply range.
Is the R5F100AAASP#X0 pin-compatible with other RL78/G13 variants in the same package?
No - while R5F100AAASP#X0 shares the 30-pin LSSOP package with other RL78/G13 members like R5F100ACASP#X0 or R5F100ADASP#X0, pin functions differ across memory variants due to differing peripheral mappings; always verify pin configuration against the specific device's datasheet section "Pin Configuration".
