Product details
Overview
R5F101ADASP#30 from Renesas is a 30-pin, industrial-grade RL78/G13 16-bit microcontroller with 48 KB flash memory, 4 KB data flash, and 2 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (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 motor drives.
For engineers reviewing the R5F101ADASP#30 datasheet, R5F101ADASP#30 pinout, R5F101ADASP#30 application, or R5F101ADASP#30 equivalent, key selection criteria include its 30-pin LSSOP package, absence of on-chip data flash (R5F101x series), industrial temperature rating (D suffix), and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F101ADASP#30 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). Its memory map spans 1 MB address space, with flash organized in 1 KB blocks and security features including block erase prohibition and flash shield window.
Peripherals include up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, real-time clock with calendar/alarm/correction functions, 16-bit timers (up to 16 channels), and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C-each configurable across multiple channels depending on pin assignment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100ADASP#30 | Same 30-pin LSSOP package and 48 KB flash, but includes 4 KB data flash and operates at same industrial temperature range. | Preferred where EEPROM-like nonvolatile data storage (e.g., calibration tables, event logs) is required without external SPI flash. | Select R5F100ADASP#30 when persistent data logging or parameter retention across power cycles is mandatory. |
| R5F101AGASP#30 | Same R5F101x series (no data flash), but offers 128 KB flash and 12 KB RAM in identical 30-pin LSSOP package. | Better suited for applications needing larger firmware footprint (e.g., USB stack, BLE host protocol) or complex state machines. | Choose R5F101AGASP#30 when firmware size exceeds 48 KB or additional RAM is needed for buffering or RTOS tasks. |
Compared with R5F101ADASP#30, R5F100ADASP#30 adds data flash for reliable parameter storage but increases cost and complexity, while R5F101AGASP#30 trades flash density for scalability-enabling future firmware growth without PCB redesign.

FAQ
What is the flash memory configuration of the R5F101ADASP#30?
The R5F101ADASP#30 contains 48 KB of code flash memory organized in 1 KB blocks, with no on-chip data flash (confirmed by RL78/G13 family designation "101" meaning data flash not provided). This configuration supports secure firmware updates via boot swap and flash shield window functions, and is optimized for applications where parameter storage is handled externally or via emulated EEPROM in code flash.
Does the R5F101ADASP#30 support hardware debugging without external tools?
Yes, the R5F101ADASP#30 integrates a full on-chip debug circuit accessible via TOOLRxD/TOOLTxD/TOOLCLK pins. It supports flash programming, breakpoint setting, and real-time variable monitoring directly through Renesas E2 studio and CS+ IDE-eliminating the need for external JTAG emulators in most development and production programming scenarios.
What is the maximum ADC resolution and channel count supported by the R5F101ADASP#30?
The R5F101ADASP#30 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and integrated temperature sensor, both usable only in high-speed main (HS) mode. The ADC supports scan mode, group conversion, and hardware-triggered sampling synchronized to timers.
Can the R5F101ADASP#30 operate reliably in industrial environments with wide temperature swings?
Yes, the R5F101ADASP#30 is rated for industrial operation from –40°C to +85°C (D-grade), with built-in voltage detector (LVD) offering 14 selectable threshold levels and power-on-reset (POR) circuitry. Its ultra-low-power STOP mode (0.57 μA with RTC + LVD active) ensures consistent timing and fault detection even under brown-out conditions common in factory-floor power distribution.
Which serial communication protocols are natively supported on the R5F101ADASP#30?
The R5F101ADASP#30 natively supports CSI (SPI-compatible), UART/LIN bus, and I²C protocols. It provides 2 CSI channels, 2 UART/LIN channels, and 3 I²C channels-all multiplexed onto shared pins (e.g., P10/P11/P12). These interfaces operate independently and can be used concurrently without resource conflict, enabling multi-protocol connectivity in compact designs.
