Product details
Overview
R5F100SHAFB#V0 from Renesas is a 128-pin LFQFP (0.5 mm pitch), 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100SHAFB#V0 datasheet, R5F100SHAFB#V0 pinout, R5F100SHAFB#V0 application, or R5F100SHAFB#V0 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, integrated RTC + LVD + BGO data flash, 10-bit 26-channel ADC, and support for LIN/UART/I²C/SPI interfaces in extended temperature (–40°C to +105°C) industrial environments.
Technical Context
The R5F100SHAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, 2–4 channel DMA, 16× UART/LIN-capable serial channels, 3–10× I²C/Simplified I²C channels, and 2–8× CSI (SPI-compatible) interfaces - all accessible via 120 GPIO pins with N-ch open-drain, TTL input, and pull-up options.

FAQ
What is the operating temperature grade of R5F100SHAFB#V0?
R5F100SHAFB#V0 is rated for industrial operation from –40°C to +105°C (G-grade), verified per Renesas specification R01DS0131EJ0380. This makes it suitable for deployment in harsh environments such as factory automation cabinets, outdoor HVAC units, and energy infrastructure enclosures where ambient heat exceeds +85°C.
Does R5F100SHAFB#V0 support in-circuit debugging?
Yes, R5F100SHAFB#V0 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses the dedicated SWJ-DP interface (pins P00/P01), enabling full breakpoint, watchpoint, and memory inspection capabilities without requiring additional debug hardware headers.
How many UART/LIN channels does R5F100SHAFB#V0 provide?
R5F100SHAFB#V0 supports up to four UART channels, each capable of LIN 2.2 protocol operation including auto-baud detection, sync field generation, and checksum handling. All four channels are independently configurable and can operate simultaneously - essential for multi-node LIN cluster management in industrial control panels.
Can R5F100SHAFB#V0 execute code while rewriting data flash?
Yes, R5F100SHAFB#V0 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash memory while data flash is being rewritten - enabling uninterrupted real-time tasks like sensor logging, OTA update staging, or event timestamping during firmware maintenance.
What is the maximum ADC sampling rate on R5F100SHAFB#V0?
The 10-bit ADC in R5F100SHAFB#V0 achieves a maximum conversion time of 1.2 μs per sample (≈833 kSPS) under optimal conditions: VDD ≥ 3.0 V, internal clock source, and single-channel sequential mode. Actual throughput depends on channel count, resolution setting, and sampling trigger method - detailed timing is specified in Section 24.5 of R01DS0131EJ0380.
