Product details
Overview
R5F51406ADFL#30 from Renesas is a 48 MHz, 32-bit RXv2 core MCU with 256 KB flash, 64 KB SRAM, and 8 KB data flash, featuring integrated CAN, 12-bit A/D (11 channels), dual 8-bit D/A, capacitive touch sensing (24-key self-capacitance), RTC, FPU, and IEC60730 safety support - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and low-power operation.
For engineers reviewing the R5F51406ADFL#30 datasheet, R5F51406ADFL#30 pinout, R5F51406ADFL#30 application, or R5F51406ADFL#30 equivalent, this page delivers verified package mapping (PLQP0048KB-B, 48-pin LFQFP), confirmed peripheral availability (CAN, CTSU2SL, S12ADE, AESA not included), exact clock domain assignments (ICLK ≤ 48 MHz, PCLKB ≤ 32 MHz), and validated alternative options for migration or sourcing continuity.
Technical Context
The R5F51406ADFL#30 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark @ 48 MHz, and ultra-compact variable-length instruction set. Its memory subsystem includes zero-wait-state SRAM, 32 MHz–48 MHz one-wait-cycle flash access, and background-programmable 8 KB data flash rated for 1M erase/program cycles.
Peripherals are orchestrated via ELC event linking and MPC pin multiplexing: CAN module (ISO11898-1, 1 Mbps, 16 mailboxes) operates independently of CPU wake-up; MTU2a provides six 16-bit timer channels with complementary PWM and phase counting; CTSU2SL supports 24-key self-capacitance touch on this 48-pin variant per Table 1.2.

FAQ
What is the maximum operating frequency and core type of the R5F51406ADFL#30?
The R5F51406ADFL#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark performance at this speed and includes an IEEE-754-compliant 32-bit floating-point unit. The core uses a 5-stage pipeline, variable-length instructions, and supports DSP operations including 32-bit multiply-accumulate.
Does the R5F51406ADFL#30 include an integrated CAN controller, and what standard does it support?
Yes, the R5F51406ADFL#30 integrates a single-channel CAN module (RSCAN) compliant with ISO11898-1, supporting both standard and extended frames at up to 1 Mbps. It provides 16 configurable mailboxes and operates independently via ELC triggering - however, an external CAN transceiver is required for physical layer interfacing.
How many capacitive touch sensing channels does the R5F51406ADFL#30 support, and which method is available?
The R5F51406ADFL#30 supports 24 capacitive touch keys using the self-capacitance method via CTSU2SL. Mutual capacitance (8×8 matrix) is not available on this 48-pin variant per Table 1.2; that capability is reserved for larger packages like the 80-pin RX140 devices.
What are the memory resources available on the R5F51406ADFL#30?
The R5F51406ADFL#30 includes 256 KB of on-chip flash memory (with 1-wait access above 32 MHz), 64 KB of zero-wait-state SRAM, and 8 KB of data flash rated for 1,000,000 program/erase cycles.
