Product details
Overview
R5F100LDGFA#X0 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar support. It operates from 1.6–5.5 V, delivers 41 DMIPS at 32 MHz, and targets battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100LDGFA#X0 datasheet, R5F100LDGFA#X0 pinout, R5F100LDGFA#X0 application, or R5F100LDGFA#X0 equivalent, key selection criteria include ultra-low-power operation (0.57 μA in RTC+LVD mode), integrated 10-bit ADC with up to 26 channels, hardware UART/LIN and I²C interfaces, and industrial-grade temperature range (−40°C to +105°C).
Technical Context
The R5F100LDGFA#X0 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual power domains enabling independent RTC and LVD operation during deep sleep.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with calendar/alarm/correction, one watchdog timer, and DMA controller with up to four channels-enabling deterministic timing for motor control and sensor polling without CPU intervention.

FAQ
What is the maximum operating frequency and performance of the R5F100LDGFA#X0?
The R5F100LDGFA#X0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction execution time - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed mode - enabling precise trade-offs between performance and power in the R5F100LDGFA#X0.
Does the R5F100LDGFA#X0 include an integrated real-time clock (RTC)?
Yes, the R5F100LDGFA#X0 integrates a full-featured RTC with calendar support (99-year range), alarm function, and clock correction capability. It operates independently in STOP mode using the dedicated 32.768 kHz subsystem clock, consuming only 0.57 μA - a key feature confirmed in the R5F100LDGFA#X0 datasheet for time-critical industrial applications.
What analog peripherals are available on the R5F100LDGFA#X0?
The R5F100LDGFA#X0 includes a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and on-die temperature sensor. These features enable direct measurement of analog sensors, battery voltage, and thermal conditions without external components - all verified in the R5F100LDGFA#X0 electrical characteristics table.
Is the R5F100LDGFA#X0 pin-compatible with other RL78/G13 variants?
The R5F100LDGFA#X0 uses a 64-pin LQFP-0.65mm package and shares identical pinout with other 64-pin RL78/G13 members in the same package type (e.g., R5F100LCAFA#X0, R5F100LLAFA#X0). However, functional differences exist across memory sizes and data flash presence - so while mechanical compatibility is guaranteed, firmware and peripheral initialization must match the R5F100LDGFA#X0's specific configuration.
What power-saving modes does the R5F100LDGFA#X0 support?
The R5F100LDGFA#X0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with RTC and LVD active, it draws just 0.57 μA - validated in the R5F100LDGFA#X0 datasheet under TA = −40°C to +105°C. SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate while CPU remains halted, optimizing responsiveness in event-driven applications.
