Product details
Overview
R5F51406BGNE#10 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 256 KB on-chip flash, 64 KB SRAM, 8 KB data flash, single-precision FPU, AES-128/256 hardware accelerator, and capacitive touch sensing supporting up to 36 keys. It integrates CAN 2.0B (1 Mbps), 12-bit A/D (18 channels, 0.67 µs conversion), dual 8-bit D/A, RTC, and operates from 1.8–5.5 V across –40 to +105°C for industrial control and smart sensor nodes.
For engineers reviewing the R5F51406BGNE#10 datasheet, R5F51406BGNE#10 pinout, R5F51406BGNE#10 application, or R5F51406BGNE#10 equivalent, this page delivers verified technical context, package mapping to PWQN0048KC-A (7×7 mm HWQFN, 0.5 mm pitch), confirmed 48-pin pinout, real-world use cases in motor control and IEC60730-compliant appliances, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The R5F51406BGNE#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 204 CoreMark at 48 MHz. It includes an IEEE-754-compliant 32-bit FPU, on-chip 32×32→64-bit multiplier, and 32÷32→32-bit divider completing in two cycles.
Its peripheral set is optimized for deterministic real-time control: ELC enables event-triggered module operation without CPU wake-up; MTU2a provides six 16-bit timer channels with complementary PWM and phase counting; and the S12ADE A/D converter supports double-trigger mode for motor current sampling and per-channel programmable sampling time.

Yes, the R5F51406BGNE#10 integrates a CAN module (RSCAN) compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) frame formats. It operates at up to 1 Mbps data rate and includes 16 configurable mailboxes for flexible message filtering and prioritization. This makes the R5F51406BGNE#10 appropriate for industrial fieldbus networks and automotive subsystems requiring robust, noise-immune serial communication-without requiring external CAN transceivers beyond physical layer interfacing.
What are the memory resources available on the R5F51406BGNE#10, and how is data flash endurance specified?
The R5F51406BGNE#10 includes 256 KB of on-chip flash memory for program storage, 64 KB of SRAM with zero wait states, and 8 KB of data flash rated for 1,000,000 program/erase cycles (typical). Data flash supports background operation (BGO), allowing concurrent read/write operations-critical for over-the-air firmware updates and parameter logging in deployed systems. All memory is accessible at 1.8 V, enabling low-voltage battery-powered operation while maintaining full functionality of the R5F51406BGNE#10.
How does the capacitive touch sensing unit (CTSU) function on the R5F51406BGNE#10, and what is its key capability?
The R5F51406BGNE#10 integrates CTSU2SL, supporting self-capacitance mode for up to 36 independent touch keys using a single pin per key-requiring no external components. It features automatic correction for environmental drift (e.g., humidity, temperature) and operates reliably across the full –40 to +105°C range. This capability allows the R5F51406BGNE#10 to serve as a standalone HMI controller in harsh environments, eliminating the need for dedicated touch controller ICs and reducing system BOM and firmware complexity.
What IEC60730 safety features are built into the R5F51406BGNE#10, and how do they assist certification?
The R5F51406BGNE#10 includes hardware-assisted IEC60730 compliance features: a data operation circuit (DOC) for RAM testing, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) self-test, and A/D converter disconnection detection. These reduce manual firmware verification burden and enable automated runtime checks. For certified designs, these features directly map to Class B requirements-allowing the R5F51406BGNE#10 to serve as the safety-monitoring element in power supplies, motor drives, and appliances without external safety monitors.
