Product details
Overview
R5F100GDAFB#10 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and DMA - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GDAFB#10 datasheet, R5F100GDAFB#10 pinout, R5F100GDAFB#10 application, or R5F100GDAFB#10 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, integrated data flash with background operation, and support for SNOOZE mode for low-latency wake-up from ultra-low-power states.
Technical Context
The R5F100GDAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, calendar-based real-time clock with alarm and correction, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and up to ten I²C/Simplified I²C channels - all accessible via 39 programmable I/O pins with N-ch open-drain capability and multi-voltage interface support (1.8/2.5/3.0 V).

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GDAFB#10?
The R5F100GDAFB#10 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. The core also supports ultra-low-speed operation at 32.768 kHz (30.5 μs/instruction) for RTC and LVD monitoring with minimal power draw - a key enabler for always-on industrial monitoring systems.
Does the R5F100GDAFB#10 support in-system programming and secure firmware updates?
Yes, the R5F100GDAFB#10 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features for firmware security. Self-programming is enabled with boot swap functionality, allowing safe dual-bank firmware updates without runtime interruption - critical for maintaining uptime in remote industrial deployments of the R5F100GDAFB#10.
How many analog input channels does the R5F100GDAFB#10 ADC support, and what reference options are available?
The R5F100GDAFB#10 integrates a 10-bit A/D converter with up to 26 analog input channels. It supports external reference voltages or the internal 1.45 V reference, which is factory-trimmed and temperature-compensated. The ADC also includes a built-in temperature sensor - usable only in HS (high-speed main) mode - enabling ambient temperature monitoring without external components in designs based on the R5F100GDAFB#10.
What low-power modes are available on the R5F100GDAFB#10, and what is the lowest achievable current consumption?
The R5F100GDAFB#10 provides HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. SNOOZE mode allows serial interfaces to remain active for wake-up triggering while the CPU is halted - reducing average power in intermittent communication scenarios without sacrificing responsiveness in the R5F100GDAFB#10.
Is the R5F100GDAFB#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GDAFB#10 is fully pin-compatible with all other RL78/G13 devices in the 48-pin LFQFP (FB) package, including R5F100GKAFB#10 and R5F101GDAFB#10. Pin functions, power/ground locations, and debug interface assignments are identical across this package group - enabling hardware reuse and migration paths within the same footprint while varying flash size, data flash presence, or memory configuration in the R5F100GDAFB#10 design family.
