Product details
Overview
R5F100LDAFA#X0 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensors and motor control edge nodes.
For engineers reviewing the R5F100LDAFA#X0 datasheet, R5F100LDAFA#X0 pinout, R5F100LDAFA#X0 application, or R5F100LDAFA#X0 equivalent, key selection criteria include its -40°C to +85°C industrial temperature rating, on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and 1.6–5.5 V single-supply operation.
Technical Context
The R5F100LDAFA#X0 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). It features dual power domains enabling independent peripheral clock gating and multiple low-power modes (HALT, STOP, SNOOZE) for deterministic wake-up latency.
Its memory subsystem includes 128 KB code flash (1 KB block size, security-locked erase/write), 8 KB data flash with 1M-cycle endurance and background operation (BGO), and 12 KB SRAM - with flash library RAM usage starting at address F7F00H per device family configuration.

FAQ
What is the maximum operating frequency of the R5F100LDAFA#X0?
The R5F100LDAFA#X0 supports up to 32 MHz operation using its high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C). External crystal or clock sources can also drive the system up to 20 MHz, with the internal PLL enabling full 32 MHz performance without external components.
Does the R5F100LDAFA#X0 support in-system programming via standard interfaces?
Yes, the R5F100LDAFA#X0 supports in-system programming via its 2-pin SWD interface (SWDIO/SWCLK), enabling full flash read/write/debug without requiring a dedicated bootloader or UART-based protocol. The on-chip debug function allows secure, production-ready firmware updates.
How many analog input channels does the R5F100LDAFA#X0 provide, and what is the ADC resolution?
The R5F100LDAFA#X0 provides 26 analog input channels with a 10-bit successive approximation ADC. It includes internal 1.45 V reference voltage and an integrated temperature sensor - both accessible only in HS (high-speed main) mode per the datasheet specification.
What low-power modes are available on the R5F100LDAFA#X0, and what is the lowest current consumption?
The R5F100LDAFA#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA - verified at VDD = 3.0 V and TA = 25°C. Wake-up from STOP is possible via external interrupt, RTC alarm, or LVD event within microseconds.
Is the R5F100LDAFA#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LQFP-0.65mm package (e.g., R5F100LCAFA#X0, R5F100LEAFA#X0, R5F101LDAFA#X0) share identical pinouts and electrical characteristics. This enables drop-in replacement across memory/configurations without PCB revision - subject to software compatibility.
