Product details
Overview
R5F101AAASP#V0 from Renesas is a 30-pin, 16 KB flash, no data flash, ultra-low-power 16-bit RL78/G13 MCU operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with 66 μA/MHz active current and 0.57 μA RTC+LVD standby mode - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101AAASP#V0 datasheet, R5F101AAASP#V0 pinout, R5F101AAASP#V0 application, or R5F101AAASP#V0 equivalent, key selection criteria include its LSSOP-30 package, absence of on-chip data flash, -40°C to +85°C industrial-grade temperature range (A-grade), and integrated 10-bit ADC with 6-channel analog input capability.
Technical Context
The R5F101AAASP#V0 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 ultra-low-speed mode). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by a dedicated low-speed oscillator.
Its peripheral set includes up to 2 UART/LIN channels, 3–10 I²C/Simplified I²C interfaces, 2–8 CSI (SPI-compatible) channels, 8–16 16-bit timers, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable under single-supply operation from 1.6 V.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101AAASP#V0?
The R5F101AAASP#V0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's optimized 3-stage pipeline execution efficiency under typical compiler-optimized code, enabling responsive real-time control in resource-constrained applications.
Does the R5F101AAASP#V0 include on-chip data flash memory?
No, the R5F101AAASP#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), this variant provides only 16 KB of code flash and relies on external nonvolatile memory (e.g., EEPROM or FRAM) for parameter storage or firmware update staging.
What package type and pin count does the R5F101AAASP#V0 use?
The R5F101AAASP#V0 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch), designated by the "SP" suffix and "#V0" tray packaging code. This JEDEC-standard package supports automated assembly and offers robust thermal and mechanical performance for industrial PCB layouts.
What is the operating temperature range specified for the R5F101AAASP#V0?
The R5F101AAASP#V0 is rated for an operating ambient temperature range of -40°C to +85°C, conforming to the "A" grade classification in the RL78/G13 family. This makes it suitable for industrial control, building automation, and outdoor consumer equipment where extended thermal reliability is required.
Which analog features are integrated into the R5F101AAASP#V0?
The R5F101AAASP#V0 integrates an 8/10-bit successive-approximation ADC with up to 6 analog input channels, internal 1.45 V reference voltage, and a calibrated temperature sensor. These features are accessible via pins P20–P22 and related ANIx functions, enabling direct sensor interfacing without external signal conditioning components.
