Product details
Overview
R5F101GCAFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GCAFB#10 datasheet, R5F101GCAFB#10 pinout, R5F101GCAFB#10 application, or R5F101GCAFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash programming via external library - critical for firmware-over-the-air updates in field-deployed embedded systems.
Technical Context
The R5F101GCAFB#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), and 1 MB address space. It integrates dual DMA channels, 16×16-bit multiplier/divider/MAC unit, and on-chip debug circuitry with boot swap capability.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, calendar-based RTC with alarm/correction, watchdog timer with dedicated low-speed oscillator, and three I²C/Simplified I²C channels - all configurable under ultra-low-power operation with voltage detector (LVD) interrupt/reset across 14 levels and power-on-reset (POR) circuit.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GCAFB#10?
The R5F101GCAFB#10 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in this mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling adaptive performance/power trade-offs in real-time firmware.
Does the R5F101GCAFB#10 include on-chip data flash memory?
No, the R5F101GCAFB#10 does not include on-chip data flash memory. The "101" prefix in the part number explicitly indicates no data flash, unlike "100" variants (e.g., R5F100GCAFB#10) which integrate 4 KB of data flash. Applications requiring nonvolatile parameter storage must use external EEPROM or rely on code flash wear-leveling techniques.
What temperature grade does the R5F101GCAFB#10 support?
The R5F101GCAFB#10 is rated for industrial operation from -40°C to +85°C (D temperature grade). This is confirmed by the "D" suffix in its full ordering code and aligns with Renesas' specification for reliability in harsh environments such as factory floors, outdoor metering enclosures, and HVAC equipment.
Which communication interfaces are supported by the R5F101GCAFB#10?
The R5F101GCAFB#10 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). These interfaces are multiplexed across GPIO pins and configurable via register settings - allowing flexible peripheral assignment without hardware redesign.
How does the R5F101GCAFB#10 achieve ultra-low-power operation?
The R5F101GCAFB#10 achieves ultra-low-power operation through multiple hardware features: HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC + LVD), and SNOOZE mode (fast wake-up from low-power sleep). It also includes an on-chip voltage detector with 14 selectable threshold levels and power-on-reset circuit - ensuring robust operation across varying supply conditions.
