Product details
Overview
R5F101GAAFB#30 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar function - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GAAFB#30 datasheet, R5F101GAAFB#30 pinout, R5F101GAAFB#30 application, or R5F101GAAFB#30 equivalent, key selection criteria include its no-data-flash configuration, -40°C to +85°C industrial temperature grade (D-grade), LFQFP-48 7×7 mm 0.5-mm pitch package, and support for SNOOZE mode operation with background data flash rewriting.
Technical Context
The R5F101GAAFB#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 integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Peripheral integration includes 8-channel 16-bit timers, 1-channel 12-bit interval timer, 1-channel real-time clock with alarm/calendar, 2–4 channel DMA controller, and serial interfaces: 2–8 CSI (SPI-compatible), 2–4 UART/LIN, and 3–10 I²C channels - all configurable without external timing components.

FAQ
What is the flash memory configuration of the R5F101GAAFB#30?
The R5F101GAAFB#30 contains 128 KB of code flash memory and zero data flash memory, as indicated by the '101' prefix in its part number (per Renesas RL78/G13 documentation). This eliminates data flash wear management overhead and reduces firmware complexity for applications that store parameters in external EEPROM or use code flash for both program and configuration data.
Does the R5F101GAAFB#30 support real-time clock functionality?
Yes, the R5F101GAAFB#30 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt capability, and hardware clock correction - all operational in STOP mode with only 0.57 μA current draw, enabling precise time-stamping in battery-powered applications without external RTC ICs.
What package type and pin pitch does the R5F101GAAFB#30 use?
The R5F101GAAFB#30 uses a 48-pin LFQFP package (7 × 7 mm body, 0.5-mm lead pitch), identified by the 'FB' suffix and '#30' tray packaging code. This fine-pitch QFP enables high I/O density while maintaining compatibility with standard surface-mount assembly processes and reflow profiles.
Can the R5F101GAAFB#30 operate from a single 1.8 V supply?
Yes, the R5F101GAAFB#30 operates across a 1.6 V to 5.5 V supply range, fully functional at 1.8 V. At this voltage, it supports up to 16 MHz operation (20.5 DMIPS), retains full peripheral functionality including ADC and RTC, and achieves sub-1 μA STOP mode current - ideal for single-cell LiFePO₄ or dual-cell alkaline systems.
How many analog input channels does the R5F101GAAFB#30 support?
The R5F101GAAFB#30 supports up to 26 analog input channels (ANI0–ANI25) with its 10-bit successive-approximation ADC. Input channels are distributed across P20–P27, P30–P37, P40–P47, and P50–P53 pins, and the ADC includes internal 1.45 V reference and temperature sensor - enabling direct thermal monitoring without external components.
