Product details
Overview
R5F101GHDFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and real-time clock with calendar function - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GHDFB#V0 datasheet, R5F101GHDFB#V0 pinout, R5F101GHDFB#V0 application, or R5F101GHDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D suffix), and integrated peripherals including UART/LIN, I²C, CSI, 16-bit timers, and hardware multiplier/divider.
Technical Context
The R5F101GHDFB#V0 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 subsystem clock). It integrates a 12-bit interval timer, real-time clock with 99-year calendar and alarm, and watchdog timer with dedicated low-speed oscillator.
Peripherals include up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 UART/LIN interfaces, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control without external timing components.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GHDFB#V0?
The R5F101GHDFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects integer instruction throughput using the EEMBC CoreMark benchmark under standard conditions (code in flash, no wait states), and is achievable with the high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C.
Does the R5F101GHDFB#V0 include on-chip data flash memory?
No, the R5F101GHDFB#V0 does not include on-chip data flash memory. Per the RL78/G13 family naming convention, the "101" prefix indicates no data flash, distinguishing it from "100"-series variants like R5F100GHDFB#V0 which integrate 8 KB of data flash. Firmware must use code flash sectors or external memory for non-volatile parameter storage.
What package type and pin count does the R5F101GHDFB#V0 use?
The R5F101GHDFB#V0 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.5 mm lead pitch. The "FB" suffix in the part number explicitly denotes LFQFP, and the "#V0" packaging code indicates tray delivery - confirmed in Renesas document R01DS0131EJ0380 Table 1-1 for 48-pin mounted variants.
What is the operating temperature range specified for the R5F101GHDFB#V0?
The R5F101GHDFB#V0 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its full ordering code. This is distinct from consumer-grade "A" (-40°C to +85°C, same range but different qualification) and extended industrial "G" (-40°C to +105°C) variants - the "D" grade meets JEDEC JESD47 stress testing requirements for industrial applications.
Which serial communication interfaces are supported by the R5F101GHDFB#V0?
The R5F101GHDFB#V0 supports three serial interface types: up to 4 UART/LIN channels (with automatic LIN header detection), up to 10 I²C/Simplified I²C channels (standard/fast mode), and up to 8 CSI channels (SPI-compatible with master/slave operation). All are independently configurable and support DMA transfers to minimize CPU overhead during high-throughput sensor communication.
