Product details
Overview
R5F100GLDFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GLDFB#30 datasheet, R5F100GLDFB#30 pinout, R5F100GLDFB#30 application, or R5F100GLDFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 7×7 mm 0.5-mm pitch package (FB suffix), and support for background data flash rewriting with 1M-cycle endurance.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GLDFB#30?
The R5F100GLDFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling adaptive performance/power trade-offs in real-time applications.
Does the R5F100GLDFB#30 support in-system programming and secure firmware updates?
Yes, the R5F100GLDFB#30 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus flash shield window protection. These features allow authenticated field firmware updates without external programmers and prevent unauthorized access to code flash contents during development or deployment.
How many analog input channels does the R5F100GLDFB#30 ADC support, and what reference options are available?
The R5F100GLDFB#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports VDD as the reference source and includes an internal 1.45 V precision reference voltage (AVREFP/AVREFM pins), enabling accurate measurements independent of supply fluctuations - critical for metrology and sensor conditioning.
What power-saving modes are available on the R5F100GLDFB#30, and what is the lowest achievable current draw?
The R5F100GLDFB#30 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across the full -40°C to +105°C industrial temperature range. This enables multi-year battery operation in always-on monitoring devices without compromising timekeeping or safety supervision.
Is the R5F100GLDFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GLDFB#30 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the LFQFP-48 (FB) package, including R5F100GLAFB#30 and R5F101GLDFB#30. This allows direct substitution within the same footprint for temperature grade or data flash requirement changes - provided software accounts for memory configuration differences.
