Product details
Overview
R5F101FDAFP#10 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, 8 KB RAM, and industrial-grade -40°C to +85°C operation. It integrates 16-bit timers (12 channels), 10-bit ADC (12 channels), UART/LIN, I²C, CSI, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F101FDAFP#10 datasheet, R5F101FDAFP#10 pinout, R5F101FDAFP#10 application, or R5F101FDAFP#10 equivalent, key selection criteria include its data flash presence (8 KB BGO-capable), absence of on-chip debug ROM (R5F101x series), LQFP-44 package with 0.8-mm pitch, and support for LIN bus physical layer via UART peripheral.
Technical Context
The R5F101FDAFP#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 uses a single 1.6–5.5 V supply and features dual-clock domains: main system clock (up to 32 MHz) and independent subsystem clock (32.768 kHz) for RTC and low-power wake-up.
Its memory subsystem includes 96 KB code flash (1 KB block size, security lock), 8 KB data flash with background operation (BGO), and 8 KB SRAM. Peripheral integration includes 12-channel 16-bit timer array, 12-channel 10-bit ADC with internal 1.45 V reference, and three serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C/Simplified I²C - all configurable per channel.

FAQ
What is the maximum operating frequency of the R5F101FDAFP#10?
The R5F101FDAFP#10 operates at up to 32 MHz using its high-speed on-chip oscillator or external crystal. At this frequency, it delivers 41 DMIPS performance with a minimum instruction execution time of 0.03125 μs. The device also supports slower subsystem clocks down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F101FDAFP#10 include on-chip debug functionality?
Yes, the R5F101FDAFP#10 includes on-chip debug functionality accessible via the TOOLRxD/TOOLTxD pins (P11/P12). It supports full-featured debugging-including breakpoints, watchpoints, and memory inspection-without requiring external debug hardware beyond a standard E2 emulator or compatible JTAG/SWD adapter.
How much data flash does the R5F101FDAFP#10 have, and what are its key characteristics?
The R5F101FDAFP#10 includes 8 KB of data flash memory. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. Rated for 1,000,000 write/erase cycles at VDD = 1.8–5.5 V, it uses 1 KB erase blocks and integrates flash shield window and boot swap functions for secure firmware updates.
Can the R5F101FDAFP#10 operate from a 1.8 V supply?
Yes, the R5F101FDAFP#10 supports operation from 1.6 V to 5.5 V, making 1.8 V fully within its specified supply range. At 1.8 V, it maintains full functionality-including 10-bit ADC operation with internal 1.45 V reference, RTC, and all serial interfaces-while drawing proportionally lower active current.
What is the difference between R5F101x and R5F100x part numbers in the RL78/G13 family?
R5F101x devices like the R5F101FDAFP#10 omit on-chip debug ROM but retain full debug capability via TOOL pins; they are optimized for cost-sensitive production units. R5F100x variants include debug ROM and are typically used during development. Both share identical peripherals, flash sizes, and electrical specifications for corresponding memory configurations.
