Product details
Overview
R5F51406ADFK#10 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 128 KB flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (15 channels), two 8-bit D/A channels, and integrated CAN 2.0B compliant with ISO11898-1 for industrial control applications.
For engineers reviewing the R5F51406ADFK#10 datasheet, R5F51406ADFK#10 pinout, R5F51406ADFK#10 application, or R5F51406ADFK#10 equivalent, key selection criteria include its LQFP-64 package (14 × 14 mm, 0.8 mm pitch), –40 to +85°C temperature grade, absence of encryption hardware (AESA/RNGA), and support for ELC-driven low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51406ADFK#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, 204 CoreMark performance at 48 MHz, and on-chip FPU compliant with IEEE-754 single-precision. Its clock system integrates HOCO (48 MHz ±1%), sub-clock (32.768 kHz), and PLL for flexible peripheral clock domain partitioning (ICLK/PCLKB/FCLK).
It supports four low-power modes including software standby (0.25 µA typ.) with 6.2 µs wake-up using LPT or MTU triggers, and features event-driven operation via ELC-enabling linked timer, ADC, and communication module activation while CPU remains asleep.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51406ADFM#30 | Same core/peripherals but LFQFP-64 (10×10 mm, 0.5 mm pitch); includes RTC and CTSU2L (12-key mutual-cap) | Requires PCB redesign for smaller footprint and finer pitch; suitable where RTC calendar mode or matrix touch is needed | Select when board space is constrained and RTC functionality is required; verify thermal pad and solder stencil compatibility |
| R5F51405ADFK#30 | 128 KB flash → reduced to 64 KB; RAM 32 KB → 16 KB; no data flash; same package and temperature grade | Targeted at cost-sensitive, lower-firmware-footprint applications like simple sensor nodes or basic CAN gateways | Choose for firmware <64 KB with minimal data logging; confirm A/D channel count (15→11) and peripheral disable requirements |
Compared with R5F51406ADFK#10, R5F51406ADFM#30 offers identical performance in a smaller package with added RTC and mutual-cap touch, while R5F51405ADFK#30 trades memory capacity and data flash for lower BOM cost-both require validation of pin mapping and peripheral enablement in target firmware.

FAQ
What is the maximum operating frequency and core architecture of the R5F51406ADFK#10?
The R5F51406ADFK#10 operates at a maximum frequency of 48 MHz using the 32-bit RXv2 CPU core with 5-stage pipeline, Harvard architecture, and IEEE-754-compliant floating-point unit. It achieves 204 CoreMark performance and supports variable-length instructions for compact code density. The R5F51406ADFK#10 does not include hardware encryption accelerators (AESA/RNGA), distinguishing it from 'B' suffix variants.
Which package type and pin count does the R5F51406ADFK#10 use?
The R5F51406ADFK#10 uses the PLQP0064GA-A package: a 64-pin LQFP with 14 × 14 mm body size and 0.8 mm pin pitch. This differs from the 0.5 mm pitch LFQFP variants (e.g., R5F51406ADFM#30) and excludes the HWQFN or 32-pin options. The R5F51406ADFK#10's pinout supports full CAN, dual SCIg, I2C, RSPI, and 15-channel A/D within this footprint.
Does the R5F51406ADFK#10 include real-time clock (RTC) functionality?
No, the R5F51406ADFK#10 does not include RTC functionality. According to Table 1.2 in the datasheet, RTCB is "Not supported" for 64-pin LQFP (PLQP0064GA-A) packages in the RX140 Group. RTC is only available in 80-pin and certain 64-pin LFQFP variants (e.g., R5F51406ADFM#30). The R5F51406ADFK#10 retains LPT for low-power timing but lacks calendar/binary count modes or alarm interrupts.
What are the memory capacities and endurance specifications for the R5F51406ADFK#10?
The R5F51406ADFK#10 integrates 128 KB of on-chip flash memory (programmable at 1.8 V), 32 KB of zero-wait-state SRAM, and 8 KB of data flash rated for 1,000,000 program/erase cycles (typ.). Flash access is no-wait up to 32 MHz and one-wait from 32–48 MHz. The R5F51406ADFK#10 supports background operation (BGO) for data flash writes during code execution.
How many A/D converter channels and what resolution does the R5F51406ADFK#10 support?
The R5F51406ADFK#10 features a 12-bit successive-approximation A/D converter with 15 external input channels and one internal channel (temperature sensor). Minimum conversion time is 0.67 µs per channel when ADCLK runs at 48 MHz. Sampling time is configurable per channel, and it supports scan modes, conversion result comparison, and analog input disconnection detection. The R5F51406ADFK#10 does not support the 18-channel configuration found in 80-pin variants.
