Product details
Overview
R7F100GLF2DFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB flash, 48-KB RAM RL78/G23 16-bit microcontroller operating from 1.6 to 5.5 V, featuring 210-nA data retention current, 41-µA/MHz active current, and integrated capacitive touch sensing (CTSU2L) for human-machine interface applications in industrial control systems.
For engineers reviewing the R7F100GLF2DFB#AA0 datasheet, R7F100GLF2DFB#AA0 pinout, R7F100GLF2DFB#AA0 application, or R7F100GLF2DFB#AA0 equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for low-power embedded designs requiring RTC, UARTA/IICA/SAU interfaces, and SNOOZE mode sequencer operation.
Technical Context
The R7F100GLF2DFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a 32-bit interval timer, 1-channel RTC with alarm and correction, and 2-channel 8-bit D/A converters with realtime output function.
Its power management includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer supporting up to 32 processes using 21 command types without CPU involvement. Peripheral event linking (ELCL) allows hardware-level signal routing between timers, ADC, UARTA, and IICA without software overhead.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLF2DFB#AA0?
The R7F100GLF2DFB#AA0 supports up to 32 MHz operation using its high-speed on-chip oscillator with ±1.0% accuracy across VDD = 1.8 to 5.5 V and TA = -20 to +85°C. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device remains functional down to 1.6 V, though maximum frequency scales linearly with supply voltage below 1.8 V per Renesas specification R01DS0395EJ0140.
Does the R7F100GLF2DFB#AA0 support hardware-based encryption or secure boot features?
The R7F100GLF2DFB#AA0 does not include dedicated cryptographic accelerators or hardware secure boot circuitry. It provides flash memory block erase/write prohibition as a basic security feature and supports self-programming with boot swapping, but lacks AES, SHA, or TRNG modules. Secure firmware updates must be implemented in software using external trusted elements or host-side verification.
Can the R7F100GLF2DFB#AA0 operate from a 3.3-V supply while interfacing with 5-V peripherals?
Yes - the R7F100GLF2DFB#AA0 supports 1.6–5.5 V operation and includes N-ch open-drain I/O pins rated for 6-V withstand voltage. When powered at 3.3 V, these pins can safely interface with 5-V logic signals (e.g., RS-485 transceivers, legacy sensors) using external pull-up resistors to 5 V, eliminating level-shifter components in mixed-voltage systems.
How many independent UARTA channels does the R7F100GLF2DFB#AA0 support, and do they all support LIN-bus protocol?
The R7F100GLF2DFB#AA0 supports six UARTA channels, and all six implement full LIN-bus protocol compliance including auto-sync-break detection, checksum generation (classic/enhanced), and slave node response timing per LIN 2.2A specification. Channel selection is configured via the UARTA control registers, with each channel independently assignable to different GPIO pins using PIOR.
What is the guaranteed data retention time for the 8-KB data flash memory in the R7F100GLF2DFB#AA0 under industrial temperature conditions?
The R7F100GLF2DFB#AA0 guarantees 1,000,000 write/erase cycles for its 8-KB data flash memory at TA = -40°C to +85°C. Data retention is specified for 20 years at +85°C and 100 years at +25°C per Renesas documentation R01DS0395EJ0140. Retention is maintained during HALT/STOP modes with VDD ≥ 1.6 V or VBAT active.
