Product details
Overview
R5F101LGAFB#10 from Renesas is a 64-pin LFQFP (0.5-mm pitch), 96 KB flash, no data flash, industrial-grade RL78/G13 16-bit MCU operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), used in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101LGAFB#10 datasheet, R5F101LGAFB#10 pinout, R5F101LGAFB#10 application, or R5F101LGAFB#10 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature rating, and support for 16-bit timer arrays, UART/LIN, I²C, and 10-bit ADC with 26-channel input.
Technical Context
The R5F101LGAFB#10 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and features a 1 MB address space with four register banks of eight 8-bit registers each.
It integrates a 16-bit timer array (16 channels), real-time clock with calendar/alarm/correction, 10-bit ADC (26 inputs, internal 1.45 V reference), and serial interfaces including up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable without external components.

FAQ
Does R5F101LGAFB#10 include on-chip data flash memory?
No, R5F101LGAFB#10 does not include data flash memory. It contains 96 KB of code flash and 8 KB of RAM only. The "101" prefix in the part number explicitly denotes absence of data flash, unlike "100" variants such as R5F100LGAFB#10 which integrate 8 KB data flash. This simplifies flash management but requires external non-volatile storage for configuration or logging.
What is the operating temperature range for R5F101LGAFB#10?
R5F101LGAFB#10 is rated for industrial operation from -40°C to +85°C. The "D" suffix in its full ordering designation (implied by FB#10 tray packaging and RL78/G13 family documentation) confirms this industrial-grade specification - distinct from consumer-grade (-40°C to +85°C, "A") or extended industrial (-40°C to +105°C, "G") variants.
Which development tools support R5F101LGAFB#10 firmware debugging and programming?
R5F101LGAFB#10 is fully supported by Renesas E2 studio IDE, CS+ (formerly CubeSuite+), and the Renesas Flash Programmer. Hardware debug interfaces include on-chip debug (OCD) via SWD using the E2 Lite or E2 emulator, compatible with the 64-pin LFQFP package's dedicated debug pins (e.g., RESET, P00/P01 for SWDIO/SWCLK).
Can R5F101LGAFB#10 operate without an external crystal?
Yes, R5F101LGAFB#10 can operate without an external crystal. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance across -20°C to +85°C, enabling crystal-free designs for cost and board-space optimization - though a 32.768 kHz crystal is required for RTC calendar accuracy.
How many ADC input channels does R5F101LGAFB#10 support, and what is the resolution?
R5F101LGAFB#10 supports 26 analog input channels with 10-bit resolution. It includes internal reference voltage (1.45 V) and temperature sensor functionality. The ADC operates across the full 1.6 V to 5.5 V supply range, enabling accurate ratiometric or absolute measurements without external reference components.
