Product details
Overview
R5F100LHGFB#V0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 512 KB flash, 8 KB data flash, 32 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - used in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100LHGFB#V0 datasheet, R5F100LHGFB#V0 pinout, R5F100LHGFB#V0 application, or R5F100LHGFB#V0 equivalent, key selection criteria include its 512 KB code flash with self-programming, 32 KB RAM for real-time control stacks, 64-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature rating, and integrated low-power peripherals enabling energy-constrained embedded designs.
Technical Context
The R5F100LHGFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It supports multiple low-power modes - HALT, STOP, and SNOOZE - with on-chip POR, LVD (14-level selectable), and dedicated low-speed oscillator for watchdog operation.
Peripherals include up to 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 2–4-channel DMA, hardware multiplier/divider/MAC, and flexible serial interfaces: 2–4 UART/LIN, 3–10 I²C/Simplified I²C, and 2–8 CSI (SPI-compatible) channels - all operating across 1.6–5.5 V supply range.

FAQ
What is the maximum operating frequency and processing performance of the R5F100LHGFB#V0?
The R5F100LHGFB#V0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core features a 3-stage pipeline and configurable instruction timing - achieving a minimum instruction cycle of 0.03125 μs at 32 MHz using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across temperature and voltage ranges specified in the datasheet.
Does the R5F100LHGFB#V0 include integrated data flash memory, and what is its endurance?
Yes, the R5F100LHGFB#V0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing CPU execution from program memory during data flash rewrites - essential for real-time logging and parameter updates without interrupting system operation.
What low-power modes does the R5F100LHGFB#V0 support, and what is its lowest current draw?
The R5F100LHGFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-long operation on primary lithium batteries in metering and sensor applications.
Is the R5F100LHGFB#V0 qualified for industrial temperature operation?
Yes, the R5F100LHGFB#V0 is rated for industrial operation from -40°C to +105°C (G-grade). This qualification is confirmed by its part number suffix "G" and packaging specification (#V0 tray for LFQFP), making it suitable for harsh environments such as factory automation controllers, motor drives, and outdoor utility equipment.
How many analog input channels and what resolution does the ADC in the R5F100LHGFB#V0 provide?
The R5F100LHGFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and an integrated temperature sensor - both usable in HS (high-speed main) mode. The ADC operates across the full 1.6–5.5 V supply range, enabling direct sensing of battery voltage, thermistors, and other analog signals without external signal conditioning.
