Overview
R5F100AAASP#50 from Renesas is a 30-pin LSSOP-packaged 16-bit RL78/G13 microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26-channel), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100AAASP#50 datasheet, R5F100AAASP#50 pinout, R5F100AAASP#50 application, or R5F100AAASP#50 equivalent, key selection criteria include its 30-pin LSSOP-30 package, 16 KB code flash + 4 KB data flash allocation, 10-bit ADC with internal reference, RTC calendar support, and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F100AAASP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller with 2 channels enabling 2-clock transfers between SFR and RAM.
Its peripheral set includes one 12-bit interval timer, one real-time clock with calendar/alarm/correction functions, one watchdog timer, and serial interfaces comprising up to 2 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable under single-supply operation from 1.6 V to 5.5 V across –40°C to +85°C ambient range.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100AAASP#50?
The R5F100AAASP#50 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions (VDD = 3.3 V, TA = 25°C). The R5F100AAASP#50 achieves this throughput while maintaining ultra-low active current consumption of 66 μA/MHz.
Does the R5F100AAASP#50 include an integrated real-time clock (RTC) with calendar functionality?
Yes, the R5F100AAASP#50 integrates a full-featured RTC with calendar support spanning 99 years, alarm generation, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz sub-system clock and maintains timekeeping at 0.57 μA - a key enabler for time-stamped logging and scheduled wake-up in battery-powered devices.
What are the flash memory resources allocated in the R5F100AAASP#50, and how is data flash utilized?
The R5F100AAASP#50 contains 16 KB of code flash memory and 4 KB of dedicated data flash memory. The data flash supports background operation (BGO), allowing program execution from main flash while rewriting data sectors, and guarantees 1,000,000 write/erase cycles at VDD = 1.8–5.5 V - ideal for storing calibration constants or usage logs without external EEPROM.
Which serial communication interfaces are supported by the R5F100AAASP#50, and how many channels are available?
The R5F100AAASP#50 supports three serial interface types: up to 2 UART/LIN channels, up to 3 I²C/Simplified I²C channels, and up to 2 CSI (SPI-compatible) channels. All are software-configurable and share pins with GPIO or analog functions, enabling flexible peripheral mapping in resource-constrained designs.
What is the operating temperature range and supply voltage specification for the R5F100AAASP#50?
The R5F100AAASP#50 is rated for industrial/consumer use across –40°C to +85°C ambient temperature and operates from a single supply voltage of 1.6 V to 5.5 V. Its on-chip POR and 14-level LVD ensure reliable startup and brown-out protection across this full voltage range without external supervision circuitry.
