Product details
Overview
R5F101GKDFB#50 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and industrial-grade -40°C to +105°C operation. It integrates a real-time clock, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, 16-bit timers, DMA, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F101GKDFB#50 datasheet, R5F101GKDFB#50 pinout, R5F101GKDFB#50 application, or R5F101GKDFB#50 equivalent, key selection criteria include its 48-pin LFQFP package, absence of on-chip data flash (R5F101x series), 256 KB code flash capacity, industrial temperature rating (G suffix), and support for background data flash rewriting via BGO.
Technical Context
The R5F101GKDFB#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD (14-level selectable), and a high-accuracy ±1.0% on-chip oscillator (32 MHz max). Peripheral integration covers up to 26-channel 10-bit ADC, 16-bit timer array (16 channels), real-time clock with calendar/alarm, and multi-protocol serial interfaces (CSI, UART/LIN, I²C).

FAQ
What is the flash memory configuration of the R5F101GKDFB#50?
The R5F101GKDFB#50 contains 256 KB of on-chip code flash memory with 1 KB block size and no integrated data flash memory-consistent with the R5F101x series designation. This configuration supports robust firmware storage while relying on external nonvolatile memory or code flash emulation for parameter retention. The R5F101GKDFB#50 uses flash library RAM starting at address FAF00H for self-programming operations.
Does the R5F101GKDFB#50 support LIN bus communication?
Yes, the R5F101GKDFB#50 supports LIN bus communication through its UART peripheral, which implements LIN 2.2 protocol features including automatic sync-break detection, checksum generation, and configurable baud rates. This capability enables direct integration into automotive body electronics and industrial sub-networks without external transceivers beyond the physical layer driver.
What is the operating temperature range for the R5F101GKDFB#50?
The R5F101GKDFB#50 is rated for industrial operation from -40°C to +105°C, indicated by the 'G' suffix in its part number. This extended temperature range qualifies it for deployment in demanding environments such as factory automation controls, motor drives, and outdoor energy infrastructure where ambient thermal stress exceeds commercial-grade limits.
How does the R5F101GKDFB#50 achieve ultra-low power consumption?
The R5F101GKDFB#50 achieves ultra-low power via multiple hardware-optimized modes: STOP mode draws just 0.57 μA when only RTC and LVD remain active, HALT mode reduces current to 66 μA/MHz during active computation, and SNOOZE mode enables selective peripheral wake-up. These capabilities are enabled by the RL78 core's voltage scaling and clock gating architecture, not software-only techniques.
Is the R5F101GKDFB#50 pin-compatible with other RL78/G13 devices in 48-pin LFQFP packages?
Yes, the R5F101GKDFB#50 shares identical pinout and footprint with all RL78/G13 48-pin LFQFP variants-including R5F100x and R5F101x families-enabling drop-in replacement within the same package group. Pin functions, power domains, and I/O electrical characteristics are fully aligned per Renesas' RL78/G13 hardware manual, simplifying design reuse and migration.
