Product details
Overview
R5F101AGASP#X0 from Renesas is a 30-pin, LSSOP-packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit ADC (26 channels), RTC with calendar/alarm, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101AGASP#X0 datasheet, R5F101AGASP#X0 pinout, R5F101AGASP#X0 application, or R5F101AGASP#X0 equivalent, key selection criteria include its 30-pin LSSOP package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature rating, and support for LIN-bus UART and background data flash rewriting.
Technical Context
The R5F101AGASP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its memory subsystem includes 96 KB code flash (1 KB block size), no data flash (per R5F101x designation), and 8 KB RAM - with flash library RAM usage starting at FF300H.
It delivers 41 DMIPS at 32 MHz and supports multiple low-power states: HALT (66 μA/MHz), STOP (0.57 μA with RTC+LVD), and SNOOZE mode. Peripheral integration includes 8× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN, 2× CSI/SPI, 12-bit interval timer, watchdog timer, and DMA controller with 2 channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100AGASP#X0 | Includes 8 KB on-chip data flash; same 96 KB code flash, 8 KB RAM, and LSSOP-30 package | Required where field firmware updates or parameter storage demand non-volatile data memory | Select when background data flash rewrite (BGO) or 1M-cycle endurance is needed for configuration storage |
| R5F101AGFP#X0 | LQFP-44 package (10×10 mm, 0.8 mm pitch); identical memory map and peripheral set | Better suited for designs requiring more GPIOs (up to 40), additional UART/I²C channels, or easier prototyping | Choose for higher I/O count or standard QFP hand-solderability; pinout incompatible with LSSOP-30 |
Compared with R5F100AGASP#X0, the R5F101AGASP#X0 saves board space and cost by omitting data flash while retaining full code execution capability; versus R5F101AGFP#X0, it trades I/O scalability for compactness and thermal performance in constrained enclosures.

FAQ
Does R5F101AGASP#X0 include on-chip data flash memory?
No, R5F101AGASP#X0 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" in R5F101AGASP#X0 explicitly denotes absence of data flash, unlike R5F100x variants which include 4–8 KB. The R5F101AGASP#X0 provides 96 KB code flash only, with RAM-based data storage during operation.
What is the operating temperature range for R5F101AGASP#X0?
The R5F101AGASP#X0 is rated for industrial operation from -40°C to +105°C (G-grade). This is confirmed by the "G" suffix in the part number and validated in the RL78/G13 datasheet Section 1.1 under Operating Ambient Temperature. It is qualified for continuous operation across this full range without derating.
Which package type does R5F101AGASP#X0 use, and what are its dimensions?
R5F101AGASP#X0 uses a 30-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), specified as PLSP0030JB-B in Renesas documentation. Its body dimensions are 9.7 mm × 4.4 mm × 1.25 mm (L × W × H), with gull-wing leads compatible with standard reflow profiles.
Can R5F101AGASP#X0 operate without an external crystal?
Yes, R5F101AGASP#X0 can operate without an external crystal. Its high-accuracy on-chip oscillator supports 32 MHz operation with ±1.0% tolerance across -20°C to +85°C and 1.8–5.5 V supply, sufficient for UART/LIN timing and general-purpose control. An external 32.768 kHz crystal is optional - only required for RTC precision beyond internal RC drift.
How many analog input channels does R5F101AGASP#X0 support?
R5F101AGASP#X0 supports up to 26 analog input channels (ANI0–ANI25), as documented in the RL78/G13 datasheet Section 1.1 under A/D converter. All channels are accessible on the 30-pin LSSOP package, with ANI0–ANI7 mapped to P20–P27 pins and additional channels multiplexed onto other port pins.
