Overview
R5F100LLGFB#V0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 512 KB flash, 8 KB data flash, and 32 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in industrial motor control and sensor-based embedded systems.
For engineers reviewing the R5F100LLGFB#V0 datasheet, R5F100LLGFB#V0 pinout, R5F100LLGFB#V0 application, or R5F100LLGFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 64-pin LFQFP-0.5 mm pitch package, integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and hardware LIN bus support for automotive body electronics and factory automation interfaces.
Technical Context
The R5F100LLGFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes on-chip code flash (512 KB, 1 KB block size), data flash (8 KB, background operation enabled), and 32 KB RAM - all accessible within a 1 MB address space.
Peripheral integration centers on mixed-signal timing and communication: one 12-bit interval timer, one calendar-capable RTC, eight 16-bit timers, up to ten I²C/Simplified I²C channels, four UART/LIN channels, and two to eight CSI (SPI-compatible) interfaces. Power management includes on-chip POR, 14-level LVD, HALT/STOP/SNOOZE modes, and dedicated low-speed oscillator for watchdog operation.

FAQ
What is the maximum operating frequency and performance rating of the R5F100LLGFB#V0?
The R5F100LLGFB#V0 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard conditions. Its RL78 CPU core achieves this with a 3-stage pipeline and optimized instruction set, making it suitable for real-time control tasks such as motor commutation and sensor fusion where deterministic timing is critical. The R5F100LLGFB#V0 maintains this performance across its full 1.6 V to 5.5 V supply range.
Does the R5F100LLGFB#V0 include integrated data flash memory, and what are its endurance specifications?
Yes, the R5F100LLGFB#V0 includes 8 KB of on-chip data flash memory with background operation (BGO) support, allowing program execution during rewrites. It guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8 V to 5.5 V. This enables robust parameter storage, firmware update staging, and event logging without external non-volatile memory - a key feature distinguishing the R5F100LLGFB#V0 from data-flash-less variants like R5F101LLGFB#V0.
What package type and pin count does the R5F100LLGFB#V0 use, and is it RoHS compliant?
The R5F100LLGFB#V0 uses a 64-pin LFQFP (Low-profile Fine-pitch Quad Flat Package) with 10 × 10 mm body and 0.50-mm lead pitch. It is RoHS-compliant and rated for moisture sensitivity level 3. This package provides mechanical robustness and thermal performance suitable for industrial PCB assembly, and the #V0 suffix confirms tray packaging for automated SMT placement - consistent with the R5F100LLGFB#V0's target use in high-reliability embedded systems.
How does the R5F100LLGFB#V0 support LIN bus communication in automotive applications?
The R5F100LLGFB#V0 supports LIN 2.x communication through its UART peripheral with dedicated LIN-mode features: automatic break detection, sync field generation, and checksum calculation. It meets SAE J2602 physical layer requirements when paired with a standard LIN transceiver. This hardware-assisted LIN capability - confirmed in the R5F100LLGFB#V0 datasheet - reduces software overhead and improves timing accuracy versus bit-banged implementations, making the R5F100LLGFB#V0 well-suited for door modules, seat controls, and lighting nodes.
What low-power modes are available on the R5F100LLGFB#V0, and what is the lowest achievable current consumption?
The R5F100LLGFB#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low standby current enables multi-year battery operation in sensor nodes and remote controls. The R5F100LLGFB#V0 achieves this via clock gating, peripheral shutdown, and retention of only essential registers - verified in Renesas' official electrical characteristics table for the G-grade industrial variant.
