Product details
Overview
R5F101AFASP#30 from Renesas is a 30-pin LSSOP-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), RTC, UART, I²C, and SPI for embedded control in battery-powered industrial sensors and smart meters.
For engineers reviewing the R5F101AFASP#30 datasheet, R5F101AFASP#30 pinout, R5F101AFASP#30 application, or R5F101AFASP#30 equivalent, key selection criteria include its 30-pin LSSOP package, absence of on-chip data flash (confirmed by "101" prefix), 64 KB code flash capacity, and support for SNOOZE mode low-power serial communication.
Technical Context
The R5F101AFASP#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture separates 64 KB code flash (1 KB block size, self-programmable with boot swap) from dedicated 4 KB RAM, enabling deterministic real-time execution.
Power management includes HALT, STOP, and SNOOZE modes, with on-chip POR and 14-level LVD for robust reset control. Peripheral integration centers on mixed-signal capability: 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART (one LIN-capable), up to 10 I²C channels, and 16-bit timers including calendar RTC with alarm and correction functions.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100AFASP#30 | Same 30-pin LSSOP package and 64 KB flash, but includes 4 KB on-chip data flash (100-series) | Preferred where EEPROM-like nonvolatile data storage is required without software emulation | Select when persistent parameter storage (e.g., calibration data) must survive power loss without flash wear management |
| R5F101AGASP#30 | Same 30-pin LSSOP package, but 96 KB flash and 8 KB RAM (higher memory tier in 101-series) | Better suited for applications needing larger firmware image or deeper data buffers (e.g., OTA update staging) | Choose when future firmware expansion headroom or real-time data logging buffer size exceeds 4 KB RAM limit |
Compared with R5F100AFASP#30, the R5F101AFASP#30 trades integrated data flash for lower cost and simpler firmware design, while R5F101AGASP#30 provides scalable memory for evolving feature sets-both retain identical pinout, peripherals, and low-power behavior.

Does the R5F101AFASP#30 support real-time clock functionality?
Yes, the R5F101AFASP#30 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt capability, and hardware clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, enabling accurate timekeeping during ultra-low-power operation.
What package type and pin count does the R5F101AFASP#30 use?
The R5F101AFASP#30 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch), designated by "SP" in the suffix and confirmed in Renesas' ordering part number table. This JEDEC-standard package supports fine-pitch surface-mount assembly and offers 26 usable I/O pins plus power/ground.
How does the R5F101AFASP#30 achieve ultra-low power consumption?
The R5F101AFASP#30 achieves ultra-low power via three dedicated modes: HALT (0.23 μA), STOP (0.42 μA), and SNOOZE (serial peripheral active while CPU sleeps). Combined with 66 μA/MHz active current and 0.57 μA RTC+LVD operation, it enables multi-year battery life in applications like wireless sensors and utility meters.
Which analog features are integrated into the R5F101AFASP#30?
