Product details
Overview
R5F100SJAFB#V0 from Renesas is a 128-pin LFQFP (0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 192 KB flash, 8 KB data flash, 16 KB RAM, 52-channel 10-bit ADC, and real-time clock - deployed in battery-powered sensor nodes and motor control interfaces requiring ultra-low power (0.57 μA in RTC+LVD mode) and 1.6–5.5 V operation.
For engineers reviewing the R5F100SJAFB#V0 datasheet, R5F100SJAFB#V0 pinout, R5F100SJAFB#V0 application, or R5F100SJAFB#V0 equivalent, key selection criteria include its 128-pin LFQFP-0.5 mm package, integrated BGO-capable data flash for firmware updates, 4-channel DMA, and support for LIN-bus UART in industrial temperature range (−40°C to +105°C).
Technical Context
The R5F100SJAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). 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 up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 4× UART/LIN channels, 2× CSI/SPI channels, and hardware multiplier/divider/MAC - all operating under unified low-power HALT/STOP/SNOOZE modes with configurable voltage detector (14-level LVD) and POR.

FAQ
What is the maximum operating frequency of the R5F100SJAFB#V0?
The R5F100SJAFB#V0 supports up to 32 MHz operation using its high-accuracy on-chip oscillator (±1.0% over −20°C to +85°C). At this speed, it delivers 41 DMIPS performance with 0.03125 μs minimum instruction execution time. External crystals up to 20 MHz are also supported for applications requiring higher precision timing sources.
Does the R5F100SJAFB#V0 support LIN bus communication?
Yes, the R5F100SJAFB#V0 supports LIN bus communication through its UART peripherals, which include LIN-mode functionality compliant with LIN 2.2A and SAE J2602 standards. This enables direct connection to LIN transceivers without protocol translation, making it suitable for automotive body electronics and industrial distributed control networks.
What is the purpose of the FAF00H RAM address in the R5F100SJAFB#V0?
The FAF00H address marks the start of a dedicated RAM area used by the Flash Self-Programming Library for RL78/G13 devices. In the R5F100SJAFB#V0, this 256-byte region is reserved for flash library operations such as data flash erase/write and boot swap - and must not be allocated for user variables or stack to prevent corruption during self-programming sequences.
How many ADC channels does the R5F100SJAFB#V0 support, and what is their resolution?
The R5F100SJAFB#V0 integrates a 10-bit successive-approximation ADC supporting up to 52 analog input channels (ANI0–ANI51), including dedicated reference voltage inputs (AVREFP/AVREFM) and an on-die temperature sensor. Conversion time is programmable down to 1.5 μs per sample, and the ADC operates across the full 1.6–5.5 V supply range.
Is the R5F100SJAFB#V0 pin-compatible with other RL78/G13 128-pin variants?
Yes, the R5F100SJAFB#V0 shares identical pinout and electrical characteristics with all other RL78/G13 128-pin LFQFP variants (e.g., R5F100SHAFB#V0, R5F100SKAFB#V0, R5F100SLAFB#V0), including same VDD/VSS distribution, I/O mapping, and peripheral pin assignments - enabling drop-in replacement within the same memory/feature tier.
