Product details
Overview
R5F100FCAFP#30 from Renesas is a 44-pin LQFP-44, 96 KB flash, 8 KB data flash, 8 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100FCAFP#30 datasheet, R5F100FCAFP#30 pinout, R5F100FCAFP#30 application, or R5F100FCAFP#30 equivalent, key selection criteria include its integrated 10-bit ADC (24 channels), real-time clock with calendar/alarm, LIN-capable UART, and support for SNOOZE mode wake-up via peripheral interrupts - all within industrial-grade -40°C to +85°C operation.
Technical Context
The R5F100FCAFP#30 implements the RL78 CPU core with 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). It integrates dual-clock domains: main system clock (up to 32 MHz) and independent low-speed subsystem clock for RTC/LVD operation.
Its peripheral set includes 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and clock correction, 3× I²C/Simplified I²C channels, 2× UART/LIN channels, and 2× CSI (SPI-compatible) interfaces - all accessible via configurable GPIO with N-ch open-drain, TTL input, and on-chip pull-up options.

What is the maximum operating frequency and performance rating of the R5F100FCAFP#30?
The R5F100FCAFP#30 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard conditions. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction timing - from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed subsystem mode - enabling precise trade-offs between throughput and power consumption in the R5F100FCAFP#30.
Does the R5F100FCAFP#30 include an integrated data flash memory, and what are its endurance specifications?
Yes, the R5F100FCAFP#30 integrates 8 KB of on-chip data flash memory with background operation (BGO) capability, allowing program execution during rewrites. It supports 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. This makes the R5F100FCAFP#30 suitable for applications requiring frequent parameter updates, such as calibration storage or event logging in industrial controllers.
What analog features does the R5F100FCAFP#30 provide, and how many input channels are supported?
The R5F100FCAFP#30 includes a 10-bit successive-approximation ADC with 24 analog input channels, internal 1.45 V reference voltage, and an integrated temperature sensor. It supports single-ended and differential measurements using AVREFP/AVREFM pins. These analog capabilities are fully operational across the device's 1.6 V to 5.5 V supply range, making the R5F100FCAFP#30 well-suited for sensor interfacing in diverse industrial and consumer systems.
Is the R5F100FCAFP#30 qualified for industrial temperature operation, and what grade does it carry?
Yes, the R5F100FCAFP#30 is rated for industrial temperature operation from -40°C to +85°C and carries the 'D' grade designation per Renesas part numbering. This qualification ensures reliable operation in demanding environments such as factory automation, smart grid infrastructure, and commercial HVAC systems - a key requirement confirmed in the official RL78/G13 datasheet for the R5F100FCAFP#30.
What communication interfaces are available on the R5F100FCAFP#30, and does it support LIN bus protocols?
The R5F100FCAFP#30 provides two UART channels with built-in LIN bus support (compliant with ISO 17987), three I²C/Simplified I²C channels, and two CSI (SPI-compatible) interfaces. The UARTs can be configured for LIN master or slave operation with automatic sync-break detection and checksum generation - enabling direct integration into automotive body electronics and industrial control networks without external transceivers. This capability is natively implemented in the R5F100FCAFP#30 silicon.
