Product details
Overview
R5F100LCGFB#30 from Renesas is a 64-pin, 512 KB flash, 8 KB data flash, 32 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and DMA - deployed in industrial motor control and sensor interface modules.
For engineers reviewing the R5F100LCGFB#30 datasheet, R5F100LCGFB#30 pinout, R5F100LCGFB#30 application, or R5F100LCGFB#30 equivalent, key selection criteria include its LFQFP-64 package with 0.5 mm pitch, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, self-programmable flash with boot swap, and background data flash rewriting capability.
Technical Context
The R5F100LCGFB#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 ultra-low-speed mode). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC operation.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, calendar-based RTC with alarm and clock correction, 10-bit ADC with internal 1.45 V reference and temperature sensor, and three serial interfaces (CSI, UART/LIN, I²C) configurable across multiple channels - all operating within the same 1.6–5.5 V voltage range and full industrial temperature envelope.

FAQ
What is the maximum operating frequency of the R5F100LCGFB#30?
The R5F100LCGFB#30 supports up to 32 MHz operation using its high-accuracy on-chip oscillator (±1.0% over -40°C to +85°C). At this speed, it delivers 41 DMIPS performance with a minimum instruction execution time of 0.03125 μs. The oscillator is factory-trimmed and requires no external components.
Does the R5F100LCGFB#30 support in-system programming via UART?
Yes, the R5F100LCGFB#30 supports in-system programming (ISP) through its on-chip debug interface using the TOOLRxD and TOOLTxD pins configured as UART. This allows firmware updates in the field without removing the device from the PCB, leveraging the built-in flash self-programming capability with boot swap function.
What is the purpose of the SNOOZE mode in the R5F100LCGFB#30?
SNOOZE mode in the R5F100LCGFB#30 enables selective peripheral operation (e.g., UART receive, ADC conversion, or timer counting) while the CPU remains halted - reducing power consumption during intermittent data acquisition or communication tasks without full wake-up latency.
Can the R5F100LCGFB#30 operate from a 1.8 V supply?
Yes, the R5F100LCGFB#30 operates across a 1.6 V to 5.5 V supply range. At 1.8 V, it supports full functionality including 10-bit ADC, RTC, and all serial interfaces, making it suitable for single-cell Li-ion or two-cell alkaline battery systems without external regulators.
