Product details
Overview
R5F101FGAFP#10 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (24 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101FGAFP#10 datasheet, R5F101FGAFP#10 pinout, R5F101FGAFP#10 application, or R5F101FGAFP#10 equivalent, key selection criteria include its 44-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and compatibility with Renesas' RL78 development ecosystem including CS+ and e² studio.
Technical Context
The R5F101FGAFP#10 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 operates across 1.6–5.5 V supply and features HALT/STOP/SNOOZE low-power modes.
It includes a 10-bit A/D converter with up to 24 analog inputs, internal 1.45 V reference and temperature sensor, real-time clock with calendar/alarm/correction, and dual-channel DMA for efficient peripheral-to-memory transfers without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FGAFP#10 | Same 44-pin LQFP package and 96 KB flash, but includes 8 KB on-chip data flash and supports background rewriting (BGO) | Suitable where firmware must store calibrated sensor offsets or configuration parameters without external EEPROM | Select R5F100FGAFP#10 if non-volatile parameter storage with 1M rewrite cycles is required; otherwise R5F101FGAFP#10 reduces cost and complexity |
| RL78/G14 R5F104GKAFP#30 | Successor family with enhanced peripherals: 24-bit sigma-delta ADC, more UART/I²C channels, and larger memory (128 KB flash / 12 KB RAM) | Better suited for higher-precision metrology or multi-protocol gateways requiring extended peripheral concurrency | Choose R5F104GKAFP#30 only when new design requires >96 KB flash, sigma-delta ADC, or additional serial interfaces - legacy code compatibility is maintained |
Compared with R5F100FGAFP#10, R5F101FGAFP#10 removes data flash to lower unit cost and power, making it optimal for fixed-function controllers; versus RL78/G14, it trades advanced peripherals for proven stability, smaller footprint, and lower BOM cost in cost-sensitive industrial endpoints.

FAQ
Does R5F101FGAFP#10 include on-chip data flash memory?
No, R5F101FGAFP#10 does not integrate data flash memory. The "101" in the part number explicitly denotes the R5F101x series, which omits on-chip data flash - unlike the R5F100x series. Applications requiring non-volatile parameter storage must use external EEPROM or FRAM, or select R5F100FGAFP#10 instead.
What is the operating temperature range for R5F101FGAFP#10?
R5F101FGAFP#10 is rated for industrial operation from -40°C to +85°C. This is confirmed by the "D" grade designation embedded in the ordering code structure (R5F101FGAFP#10 maps to D-field application per Renesas documentation), making it suitable for factory-floor and outdoor equipment deployments.
Which development tools support R5F101FGAFP#10?
R5F101FGAFP#10 is fully supported by Renesas' CS+ IDE, e² studio (with GCC RL78 toolchain), and the E2 emulator Lite. Debugging uses the TOOLRxD/TOOLTxD pins (P11/P12), and flash programming is compatible with Renesas Flash Programmer and third-party tools like Segger J-Link with RL78 device support enabled.
Can R5F101FGAFP#10 operate from a 1.8 V supply?
Yes, R5F101FGAFP#10 supports 1.6 V to 5.5 V operation, so 1.8 V is within specification. At 1.8 V, maximum clock frequency is reduced to 16 MHz per the datasheet's voltage-frequency curve, and certain peripherals (e.g., high-speed ADC sampling) may require derating - full functionality is preserved at 1.8 V with appropriate timing configuration.
How many analog input channels does R5F101FGAFP#10 support?
R5F101FGAFP#10 supports up to 24 analog input channels for its 10-bit A/D converter. This includes dedicated ANI0–ANI23 pins plus shared functions on port pins such as P20/ANI0 and P21/ANI1, as defined in the RL78/G13 pin configuration table for 44-pin LQFP packages.
