Product details
Overview
R5F101GGDFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, and 8 KB RAM. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT, targeting battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F101GGDFB#X0 datasheet, R5F101GGDFB#X0 pinout, R5F101GGDFB#X0 application, or R5F101GGDFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature rating (G suffix), and integrated RTC, 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI).
Technical Context
The R5F101GGDFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 includes 1 MB address space, with flash organized in 1 KB blocks and security features like block erase prohibition.
It integrates a 10-bit A/D converter with up to 26 analog inputs, internal 1.45 V reference, and temperature sensor; a real-time clock with calendar, alarm, and clock correction; and dual serial interfaces per channel (e.g., UART/LIN and simplified I²C) across up to 10 channels - all configurable without external components.

FAQ
What is the flash memory configuration of the R5F101GGDFB#X0?
The R5F101GGDFB#X0 contains 128 KB of on-chip code flash memory organized in 1 KB erasable blocks. It does not include on-chip data flash - confirmed by the '101' prefix in the part number per Renesas documentation. This configuration supports secure boot, flash shield window protection, and self-programming with boot swap functionality.
Does the R5F101GGDFB#X0 support hardware debugging?
Yes, the R5F101GGDFB#X0 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses dedicated pins (e.g., TOOLRxD on P11) and supports breakpoints, watchpoints, and real-time variable monitoring without halting peripheral operation.
What are the key low-power modes supported by the R5F101GGDFB#X0?
The R5F101GGDFB#X0 supports HALT, STOP, and SNOOZE modes. STOP mode draws only 0.57 μA while retaining RTC and LVD operation - critical for battery-backed applications. HALT mode consumes 66 μA/MHz during active processing, and SNOOZE enables selective peripheral wake-up without full CPU restart.
Can the R5F101GGDFB#X0 operate across the full industrial temperature range?
Yes, the 'G' suffix in R5F101GGDFB#X0 denotes qualification for -40°C to +105°C ambient operation. This is verified in the RL78/G13 datasheet (R01DS0131EJ0380) and applies to all electrical specifications including flash endurance, ADC accuracy, and oscillator stability within that range.
How many serial communication interfaces does the R5F101GGDFB#X0 provide?
The R5F101GGDFB#X0 provides up to 10 serial interface channels: 2–4 UART/LIN, 3–10 simplified I²C, and 2–8 CSI (SPI-compatible) - with flexible pin mapping. All channels support independent baud rates and can operate concurrently, enabling multi-protocol connectivity in compact designs.
