Product details
Overview
R5F100GADFB#X0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 26-channel ADC, real-time clock with calendar, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered sensor nodes and motor control interfaces.
For engineers reviewing the R5F100GADFB#X0 datasheet, R5F100GADFB#X0 pinout, R5F100GADFB#X0 application, or R5F100GADFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm pitch package, G-grade temperature range (−40°C to +105°C), integrated data flash with background operation, and support for LIN-bus UART and simplified SPI/CSI peripherals in resource-constrained embedded systems.
Technical Context
The R5F100GADFB#X0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with 1M rewrite cycles, and 12 KB SRAM - all accessible via DMA channels and protected by flash shield window and boot swap functions.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with alarm/calendar, one watchdog timer, and serial interfaces: up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - configurable for mixed-signal industrial control and low-power sensing applications.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F100GADFB#X0?
The R5F100GADFB#X0 features a high-speed on-chip oscillator selectable up to 32 MHz with ±1.0% accuracy across VDD = 1.8 V to 5.5 V and TA = −20°C to +85°C. This eliminates the need for an external crystal in many timing-critical applications while maintaining sufficient precision for UART/LIN communication and ADC sampling synchronization.
Does R5F100GADFB#X0 support in-system programming and secure firmware updates?
Yes, R5F100GADFB#X0 supports self-programming with boot swap functionality and flash shield window protection. These features allow safe field firmware updates by isolating active and update code banks, and restricting read/write access to designated flash regions - critical for protecting bootloader integrity and calibrated sensor parameters in deployed R5F100GADFB#X0 units.
What are the low-power operating modes available on R5F100GADFB#X0, and what is the lowest current consumption?
R5F100GADFB#X0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption. This ultra-low quiescent current enables multi-year battery operation in wireless sensor nodes and portable diagnostic tools using the R5F100GADFB#X0 as the primary controller.
How many analog input channels and what ADC resolution does R5F100GADFB#X0 provide?
R5F100GADFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), internal 1.45 V reference voltage, and an on-chip temperature sensor. This enables direct measurement of multiple analog sensors - such as thermistors, pressure transducers, and current shunts - without external signal conditioning in R5F100GADFB#X0-based designs.
Is R5F100GADFB#X0 qualified for industrial temperature operation, and what is its rated range?
Yes, R5F100GADFB#X0 carries the 'G' suffix denoting industrial qualification with guaranteed operation from −40°C to +105°C. This extended temperature range meets requirements for under-hood automotive modules, factory-floor PLC I/O expanders, and outdoor smart infrastructure devices deploying the R5F100GADFB#X0 as the main system MCU.
