Product details
Overview
R5F101LGAFB#30 from Renesas is a 64-pin, LFQFP-0.5 mm pitch, 96 KB flash, 8 KB RAM, RL78/G13 16-bit microcontroller with true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 10-bit ADC (26 channels), RTC, UART, I²C, and SPI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101LGAFB#30 datasheet, R5F101LGAFB#30 pinout, R5F101LGAFB#30 application, or R5F101LGAFB#30 equivalent, key selection criteria include its data flash omission (vs. R5F100x variants), -40°C to +85°C industrial temperature grade (D suffix), 64-pin LFQFP package (PLQP0064KF-A), and support for background data flash rewriting via BGO mode.
Technical Context
The R5F101LGAFB#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 a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10× I²C/Simplified I²C channels, 2–4× UART/LIN interfaces, 2–8× CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating within the 1.6–5.5 V voltage range and validated for industrial ambient conditions (-40°C to +85°C).
Key Specifications

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F101LGAFB#30?
The R5F101LGAFB#30 operates up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. At this frequency, active current is rated at 66 μA/MHz (2.11 mA typical at 32 MHz, VDD = 3.3 V, TA = 25°C). Its ultra-low-power design maintains sub-μA STOP mode current (0.57 μA) with RTC and LVD active - critical for long-life battery applications.
Does the R5F101LGAFB#30 include data flash memory, and how does that affect firmware design?
No, the R5F101LGAFB#30 does not integrate data flash memory - it belongs to the R5F101x series, which omits this feature versus the R5F100x series. Firmware must use external nonvolatile memory (e.g., I²C EEPROM or SPI FRAM) for storing calibration data, device configuration, or event logs. This reduces die cost and simplifies flash wear management but adds BOM and layout complexity.
Which communication interfaces are supported on the R5F101LGAFB#30, and how many instances are available?
The R5F101LGAFB#30 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). All are configurable via software registers and share pins with GPIO functions. The 64-pin LFQFP package exposes sufficient dedicated and multiplexed pins to concurrently run 2× UART, 2× I²C, and 1× CSI without conflict - validated in Renesas' RL78/G13 hardware manual.
What is the ADC capability of the R5F101LGAFB#30, and does it include internal references?
The R5F101LGAFB#30 features an 8/10-bit successive approximation register (SAR) ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage source and a calibrated temperature sensor - both accessible via dedicated ADC channels. The ADC operates across the full 1.6–5.5 V supply range and supports scan mode, group conversion, and hardware-triggered sampling for deterministic sensor acquisition.
How is the R5F101LGAFB#30 qualified for industrial temperature operation, and what packaging supports this?
The R5F101LGAFB#30 carries the 'D' suffix, certifying qualification for industrial ambient temperature operation from -40°C to +85°C per JEDEC JESD22-A104. It is packaged in a 64-pin LFQFP (10 × 10 mm, 0.50-mm pitch) with lead finish compliant to J-STD-020 moisture sensitivity level 3 (MSL3), ensuring reliability in reflow-soldered industrial assemblies. Thermal resistance (θJA) is 40°C/W, verified under natural convection conditions.
