Product details
Overview
R5F100FDGFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (24 channels), real-time clock, and multiple serial interfaces including UART/LIN, I²C, and CSI. It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100FDGFP#30 datasheet, R5F100FDGFP#30 pinout, R5F100FDGFP#30 application, or R5F100FDGFP#30 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, and hardware multiplier/divider for deterministic control-loop execution.
Technical Context
The R5F100FDGFP#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 96 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 8 KB SRAM - all accessible under single 1.6–5.5 V supply.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, one watchdog timer, two DMA channels, and three I²C/Simplified I²C channels - enabling time-critical sensor polling, low-jitter PWM generation, and multi-device bus arbitration without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101FDGFP#30 | No data flash (0 KB); identical core, peripherals, and package. | Suitable where firmware updates occur only via external memory or factory programming. | Select when data logging or field-upgradable parameter storage is unnecessary - reduces cost and simplifies flash management. |
| STM32G071CBT6 | ARM Cortex-M0+, 128 KB flash, 36 KB RAM, no integrated RTC calendar; operates at 64 MHz. | Better suited for higher-throughput USB or cryptography workloads, but requires external RTC for calendar functions. | Choose when ARM ecosystem compatibility, larger RAM, or USB device support outweighs RL78's ultra-low-power STOP mode and built-in calendar RTC. |
Compared with R5F100FDGFP#30, R5F101FDGFP#30 removes data flash to lower cost for static-parameter applications, while STM32G071CBT6 trades RL78's sub-μA retention and calendar RTC for higher clock speed and ARM toolchain familiarity - making each optimal for distinct power/performance/feature trade-offs.

What debug and programming interfaces are available on the R5F100FDGFP#30?
The R5F100FDGFP#30 provides on-chip debug support via the dedicated TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and standard SWD/JTAG adapters. Its flash shield window and security lock bits prevent unauthorized readout, and the integrated debug circuitry enables full breakpoint, watchpoint, and real-time variable inspection without requiring additional debug headers or traces.
Is the R5F100FDGFP#30 qualified for industrial temperature operation, and what packaging does it use?
Yes, the R5F100FDGFP#30 is rated for industrial operation from −40°C to +105°C (G-grade) and is supplied in a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch).
