Overview
R5F100GAANA#40 from Renesas is a 16-bit RL78/G13 microcontroller with 128 KB flash memory, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100GAANA#40 datasheet, R5F100GAANA#40 pinout, R5F100GAANA#40 application, or R5F100GAANA#40 equivalent, key selection criteria include its 40-pin HWQFN package, integrated 10-bit 26-channel ADC, real-time clock with calendar, and support for LIN-bus UART - critical for embedded control in constrained-space, low-power systems.
Technical Context
The R5F100GAANA#40 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 integrates on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.

Its minimum instruction execution time is 0.03125 μs in high-speed mode, making it suitable for real-time control loops in motor drives and sensor processing.
Does the R5F100GAANA#40 support LIN bus communication?
Yes, the R5F100GAANA#40 supports LIN bus communication through its UART peripherals, which include hardware LIN protocol features compliant with ISO 17987. This capability is confirmed in the RL78/G13 datasheet section "Serial interface" and enables direct integration into automotive body electronics and industrial sub-networks without external transceivers.
What low-power modes are available on the R5F100GAANA#40, and what is the lowest current draw?
The R5F100GAANA#40 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified in the datasheet's "Ultra-low power consumption technology" section. This makes the R5F100GAANA#40 ideal for battery-powered applications requiring multi-year operation without maintenance.
How much flash and RAM does the R5F100GAANA#40 include, and is data flash supported?
The R5F100GAANA#40 includes 128 KB of code flash memory, 8 KB of dedicated data flash memory (rated for 1,000,000 write cycles), and 12 KB of on-chip RAM. Data flash supports background operation (BGO), allowing program execution during rewrites - a key feature confirmed in the "Data Flash Memory" section of the RL78/G13 datasheet.
What is the package type and pin count of the R5F100GAANA#40?
The R5F100GAANA#40 uses a 40-pin HWQFN package (6 × 6 mm, 0.5-mm pitch), as specified in Table 1-1 of the RL78/G13 datasheet under "40 pins / 40-pin plastic HWQFN". This compact, thermally efficient package supports high-density PCB layouts and is rated MSL3 for standard surface-mount assembly.
