Product details
Overview
R5F101GKAFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F101GKAFB#10 datasheet, R5F101GKAFB#10 pinout, R5F101GKAFB#10 application, or R5F101GKAFB#10 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), absence of on-chip data flash (R5F101x series), LFQFP-48 0.5-mm pitch package, and integrated low-voltage detection with 14 programmable levels.
Technical Context
The R5F101GKAFB#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 integrates a 12-bit interval timer, calendar-mode real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained embedded environments.

FAQ
Does R5F101GKAFB#10 include on-chip data flash memory?
No, R5F101GKAFB#10 does not include on-chip data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, this variant provides 256 KB code flash and 20 KB RAM but omits data flash - unlike the "100" series (e.g., R5F100GKAFB#10) which includes 4 KB or 8 KB. Firmware must manage nonvolatile storage externally or via code flash emulation techniques.
What is the maximum ambient operating temperature for R5F101GKAFB#10?
The R5F101GKAFB#10 is rated for industrial operation from −40°C to +105°C, confirmed by the "G" suffix in its part number and documented in the RL78/G13 datasheet Rev.3.80. This extended temperature grade enables reliable deployment in motor drives, power supplies, and outdoor industrial equipment where junction temperatures exceed standard commercial limits.
Which package type and footprint does R5F101GKAFB#10 use?
R5F101GKAFB#10 uses a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch), identified by the "FB" suffix. Its land pattern matches JEDEC MS-026, and the Renesas package code PLQP0048KF-A confirms mechanical compatibility with standard LFQFP-48 reflow profiles and pick-and-place tooling.
Can R5F101GKAFB#10 operate from a 1.8 V supply?
Yes, R5F101GKAFB#10 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, it delivers full functionality at reduced maximum frequency (≤16 MHz), with verified operation of ADC, RTC, and I/O - enabling direct integration with 1.8 V logic families and low-voltage battery systems without regulators.
How many ADC input channels does R5F101GKAFB#10 support?
R5F101GKAFB#10 supports up to 26 analog input channels for its 10-bit successive-approximation ADC, as specified in the RL78/G13 datasheet Section 1.1. These channels include dedicated pins (e.g., P20–P27, P30–P37) and multiplexed functions on port pins, with internal 1.45 V reference and temperature sensor - sufficient for multi-sensor industrial monitoring.
