Product details
Overview
R5F101GDDFB#50 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 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), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GDDFB#50 datasheet, R5F101GDDFB#50 pinout, R5F101GDDFB#50 application, or R5F101GDDFB#50 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), absence of on-chip data flash, LFQFP-48 0.5-mm pitch package, and support for background data flash programming via external library - critical for firmware update resilience in field-deployed equipment.
Technical Context
The R5F101GDDFB#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 subsystem clock), and 1 MB address space. It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable under single-supply operation without level shifters for mixed-voltage interfacing.

FAQ
What is the maximum operating frequency and power consumption of the R5F101GDDFB#50?
The R5F101GDDFB#50 operates at up to 32 MHz with 41 DMIPS performance and achieves 66 μA/MHz active current. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA - verified per R01DS0131EJ0380 datasheet Rev. 3.80, page 1. This ultra-low quiescent current makes R5F101GDDFB#50 ideal for battery-powered metering and sensing applications.
Does the R5F101GDDFB#50 include on-chip data flash memory?
No, the R5F101GDDFB#50 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Figure 1-1, page 3 of R01DS0131EJ0380), this variant omits data flash. Designers must use external EEPROM or FRAM for persistent parameter storage, or allocate code flash sectors for emulation - unlike the R5F100GDDFB#50 which includes 4 KB data flash.
What package type and pin count does the R5F101GDDFB#50 use?
The R5F101GDDFB#50 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.5 mm pin pitch (Renesas code PLQP0048KF-A). This is confirmed in Table 1-1 (page 8) of R01DS0131EJ0380, where "FB" denotes LFQFP and "G" indicates 128 KB flash. The #50 suffix specifies embossed tape packaging - suitable for automated SMT assembly.
Which serial communication interfaces are supported by the R5F101GDDFB#50?
The R5F101GDDFB#50 supports up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. These are fully independent and can operate concurrently - for example, UART0 for host communication, I²C0 for sensor readout, and CSI0 for display interface. All interfaces support clock stretching, multi-master arbitration, and programmable baud rates per R01DS0131EJ0380 section 1.1.
What is the operating temperature range and qualification grade of the R5F101GDDFB#50?
The R5F101GDDFB#50 is qualified for industrial applications with an operating ambient temperature range of −40°C to +85°C (denoted by "D" in the part number suffix per Figure 1-1, page 3). It meets JEDEC JESD22-A108 reliability standards and is rated for continuous operation in harsh environments such as factory floors and outdoor utility enclosures - distinct from consumer-grade "A" (−40°C to +85°C, non-automotive) or extended "G" (−40°C to +105°C) variants.
