Product details
Overview
R5F100FLDFP#30 from Renesas is a 44-pin LQFP-0.8mm-pitch 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (24 channels), RTC, and DMA for embedded control in industrial sensor nodes and battery-powered HMI.
For engineers reviewing the R5F100FLDFP#30 datasheet, R5F100FLDFP#30 pinout, R5F100FLDFP#30 application, or R5F100FLDFP#30 equivalent, key selection criteria include its 44-pin LQFP package, -40°C to +85°C industrial temperature grade (D), integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and support for SNOOZE mode wake-up via serial interface or external interrupt.
Technical Context
The R5F100FLDFP#30 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-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, 8 CSI (SPI-compatible) channels, 16× 16-bit timers, 12-bit interval timer, and 10-bit A/D converter with internal 1.45 V reference and temperature sensor-enabling precise analog monitoring without external components.

FAQ
What is the operating temperature range for R5F100FLDFP#30?
The R5F100FLDFP#30 is rated for industrial operation from −40°C to +85°C (D-grade), validated across the full range for flash read/write, ADC accuracy, oscillator stability, and I/O drive strength per Renesas datasheet R01DS0131EJ0380.
Does R5F100FLDFP#30 support in-system programming via UART?
Yes, R5F100FLDFP#30 supports bootloader-based in-system programming using UART channel 0 (P11/P12) with the Renesas Flash Development Toolkit (FDT), enabling field firmware updates without JTAG debugger hardware.
How many UART channels does R5F100FLDFP#30 include, and are they LIN-capable?
R5F100FLDFP#30 includes four UART channels, all supporting LIN 2.2 protocol features including auto-sync, break detection, and checksum generation - verified in the RL78/G13 hardware manual section 24.3.2.
Can R5F100FLDFP#30 operate from a single 1.8 V supply?
Yes, R5F100FLDFP#30 supports 1.6 V to 5.5 V operation; at 1.8 V, it achieves up to 8 MHz CPU speed with full peripheral functionality, including ADC (with reduced resolution tolerance) and RTC, as specified in Electrical Characteristics Table 7-1.
Is there hardware support for AES encryption in R5F100FLDFP#30?
No, R5F100FLDFP#30 does not include dedicated AES hardware acceleration; cryptographic operations must be implemented in firmware using its 16-bit MAC unit and RAM-resident libraries - confirmed by absence in the Peripheral Function List (Section 1.6) and Security Functions chapter.
