Product details
Overview
R5F101SLAFB#10 from Renesas is a 128-pin, LFQFP-0.5 mm pitch, industrial-grade RL78/G13 16-bit microcontroller with no data flash, 512 KB code flash, 32 KB RAM, and operation from -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and hardware multiplier/divider for embedded control in power-constrained systems.
For engineers reviewing the R5F101SLAFB#10 datasheet, R5F101SLAFB#10 pinout, R5F101SLAFB#10 application, or R5F101SLAFB#10 equivalent, key selection criteria include its 128-pin LFQFP package, absence of on-chip data flash, industrial temperature rating, ultra-low-power HALT/STOP/SNOOZE modes, and support for background data flash programming via external memory interface.
Technical Context
The R5F101SLAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz). It uses a single 1.6–5.5 V supply and includes on-chip POR, LVD (14-level selectable), and dedicated low-speed oscillator for watchdog timing.
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× 12-bit interval timer, 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and 3–10 channel I²C/Simplified I²C - all operating within the same voltage domain as the core.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100SLAFB#10 | Includes 8 KB data flash; identical pinout, package, and peripherals; same 512 KB code flash and 32 KB RAM. | Preferred where EEPROM-like nonvolatile parameter storage is required without external SPI flash. | Select when firmware requires frequent runtime parameter updates (e.g., calibration data, user settings). |
| R5F101MLAFB#10 | 64-pin LFQFP, 32 KB RAM, 512 KB flash; lacks 64 I/O pins and 10-bit ADC channels vs. R5F101SLAFB#10. | Suitable for space-constrained designs with reduced peripheral count (e.g., simpler motor drives or lighting controllers). | Choose for cost-optimized, lower-I/O variants where full 128-pin capability is unnecessary. |
Compared with R5F100SLAFB#10, the R5F101SLAFB#10 trades data flash for marginally lower cost and simplified flash management, while the R5F101MLAFB#10 reduces pin count and I/O to meet compact board layouts - both retain the same core performance and ultra-low-power architecture.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101SLAFB#10?
The R5F101SLAFB#10 operates at up to 32 MHz and achieves 41 DMIPS performance per the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80). This benchmark reflects integer instruction throughput under standard conditions and enables efficient execution of real-time control algorithms such as PID loops or sensor fusion without external acceleration.
Does the R5F101SLAFB#10 include on-chip data flash memory?
No, the R5F101SLAFB#10 does not include on-chip data flash memory. Its part number encoding ('101' prefix) explicitly denotes "data flash not provided", distinguishing it from '100'-series variants like R5F100SLAFB#10 which integrate 8 KB of data flash. Firmware must use code flash sectors or external memory for nonvolatile parameter storage.
What package type and pin count does the R5F101SLAFB#10 use?
The R5F101SLAFB#10 uses a 128-pin LFQFP package with 0.5 mm pitch and 14 × 20 mm body size (RENESAS code PLQP0128KD-A). The 'FB' suffix in the part number confirms the LFQFP-0.5 mm variant, and the 'SL' segment indicates 128-pin configuration within the RL78/G13 family.
What is the operating temperature range specified for the R5F101SLAFB#10?
The R5F101SLAFB#10 is rated for industrial operation from -40°C to +85°C ('D' grade). This is confirmed by the 'D' in the ordering code structure and aligns with Table 1-1 in the RL78/G13 datasheet, making it suitable for factory automation, power supplies, and outdoor equipment where extended thermal stability is required.
Which serial communication interfaces are supported by the R5F101SLAFB#10?
The R5F101SLAFB#10 supports up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. All are implemented in hardware with independent baud rate generators and FIFO buffers, enabling concurrent multi-protocol communication - for example, LIN for actuator control, I²C for sensor hubs, and UART for debugging or host interface.
