Product details
Overview
R5F51406AGFL#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 on-chip FPU, 12-bit A/D converter (11 external channels), dual 8-bit D/A outputs, capacitive touch sensing (24-key self-capacitance), CAN 2.0B interface, and IEC60730 safety support - deployed in industrial HMI and smart sensor nodes.
For engineers reviewing the R5F51406AGFL#30 datasheet, R5F51406AGFL#30 pinout, R5F51406AGFL#30 application, or R5F51406AGFL#30 equivalent, this page delivers verified package mapping (PLQP0048KB-B, 48-pin LFQFP), confirmed peripheral allocation (CAN, SCIg×2, RIIC, RSPI, MTU2×6), real-time clock omission, and encryption module exclusion per part number decoding.
Technical Context
The R5F51406AGFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 204 CoreMark at 48 MHz. It integrates a 32-bit single-precision IEEE-754 FPU and hardware divider completing division in two cycles.
Its low-power architecture supports four operating modes including software standby (0.25 µA typ.) with 6.2 µs wake-up from HOCO 32 MHz, and includes event-link controller (ELC) enabling peripheral-to-peripheral triggering without CPU intervention - critical for deterministic motor control and sensor fusion.

The R5F51406AGFL#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz, achieving 204 CoreMark performance. Its Harvard architecture uses a 5-stage pipeline and variable-length instructions to optimize code density and execution efficiency. The R5F51406AGFL#30 supports no-wait-state flash access up to 32 MHz and one-wait access from 32 to 48 MHz.
Does the R5F51406AGFL#30 include a real-time clock (RTC) module?
No, the R5F51406AGFL#30 does not include a real-time clock (RTCB) module. Per Table 1.2 in the datasheet, RTC functionality is explicitly omitted in all 48-pin variants of the RX140 Group, including R5F51406AGFL#30. This omission aligns with its target use cases - such as motor control and touch HMI - where precise calendar timekeeping is not required.
What is the flash and RAM capacity of the R5F51406AGFL#30?
The R5F51406AGFL#30 integrates 256 KB of on-chip flash memory, 64 KB of SRAM, and 8 KB of data flash. Flash supports background operation (BGO) and programming at 1.8 V, while SRAM operates with zero wait states across the full frequency range. The R5F51406AGFL#30's memory configuration is fixed per part number and cannot be upgraded or downgraded in-circuit.
Which communication interfaces are supported by the R5F51406AGFL#30?
The R5F51406AGFL#30 supports CAN 2.0B (1 Mbps), two SCIg channels (asynchronous/clock-sync/smart card), one RIIC interface (400 kbps I²C/SMBus), and one RSPI channel (16 Mbps SPI). It does not include SCIh, SCIk, or RTCB. All interfaces are fully functional in the PLQP0048KB-B package, with pin assignments validated in Table 1.4 of the datasheet.
Is the R5F51406AGFL#30 qualified for extended temperature operation?
Yes, the R5F51406AGFL#30 is rated for operation from –40°C to +105°C, as indicated by the 'G' suffix in its part number. This extended temperature grade makes it suitable for under-hood automotive applications, industrial drives, and outdoor equipment where thermal robustness is critical. The specification is guaranteed across the full voltage range (1.8–5.5 V) and all enabled peripherals.
