Product details
Overview
R5F51405AGFL#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 128 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (11 external channels), two 8-bit D/A channels, and capacitive touch sensing (24-key self-capacitance). It supports CAN, SCI, I²C, RSPI, RTC, low-power modes, and operates from 1.8–5.5 V in industrial temperature range (–40 to +105°C) for embedded control in motor drives and HMI systems.
For engineers reviewing the R5F51405AGFL#30 datasheet, R5F51405AGFL#30 pinout, R5F51405AGFL#30 application, or R5F51405AGFL#30 equivalent, key selection considerations include its 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), absence of RTC and encryption modules, 11-channel A/D, and CAN support - critical for real-time industrial sensor interface and actuator control designs.
Technical Context
The R5F51405AGFL#30 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark score at 48 MHz, and Harvard architecture with 5-stage pipeline. It integrates a 12-bit A/D converter with 0.67 µs conversion time at 48 MHz ADCLK and double-trigger mode for motor control feedback.
Its peripheral set includes one CAN module (ISO 11898-1, up to 1 Mbps), six SCI channels (asynchronous/clock-synchronous/Smart Card), one I²C bus interface (400 kbps), one RSPI (16 Mbps), MTU2a (6-channel 16-bit timer), CMT (2-channel 16-bit), LPT (16-bit low-power timer), and CTSU2SL supporting 24-key self-capacitance touch sensing - all coordinated via Event Link Controller (ELC) to minimize CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51405ADFL#30 | Same package and pinout; rated for –40 to +85°C (vs. +105°C); includes same peripherals but lower temp grade | Suitable for commercial/office environments; not qualified for under-hood or high-ambient industrial enclosures | Select when extended temperature operation is unnecessary and cost optimization is prioritized |
| R5F51403AGFL#30 | 64 KB flash / 16 KB RAM / 4 KB data flash; lacks CAN module; retains 11-channel A/D and CTSU2SL | Targeted at cost-sensitive, non-networked control tasks (e.g., basic appliance UI or fan speed control) | Choose when CAN is unused and memory footprint allows reduction to meet BOM targets |
Compared with R5F51405ADFL#30, the R5F51405AGFL#30 adds extended temperature qualification (+105°C) without peripheral trade-offs; versus R5F51403AGFL#30, it doubles flash/RAM and restores CAN - making it optimal for thermally demanding, networked industrial edge nodes.

FAQ
What is the maximum operating frequency and core type of the R5F51405AGFL#30?
The R5F51405AGFL#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 single-precision floating-point unit. The core uses a Harvard architecture with 5-stage pipeline and variable-length instructions, enabling efficient code density and deterministic real-time execution essential for motor control and sensor processing in the R5F51405AGFL#30.
Does the R5F51405AGFL#30 include a real-time clock (RTC) module?
No, the R5F51405AGFL#30 does not include a real-time clock (RTCB) module. According to Table 1.2 in the datasheet, RTC is only available in 80-pin and certain 64-pin variants of the RX140 Group; the 48-pin PLQP0048KB-B package (used by R5F51405AGFL#30) explicitly omits RTC functionality. Designers requiring calendar/timekeeping must implement external RTC or use software-based timing with the low-power timer (LPTa) and sub-clock oscillator - both present in the R5F51405AGFL#30.
What communication interfaces are supported by the R5F51405AGFL#30?
The R5F51405AGFL#30 supports one CAN module (ISO 11898-1, up to 1 Mbps), six SCI channels (asynchronous/clock-synchronous/Smart Card), one I²C bus interface (400 kbps, SMBus-compatible), and one RSPI channel (16 Mbps). It does not include Ethernet, USB, or SDIO. All interfaces are fully integrated with the Event Link Controller (ELC), allowing hardware-triggered transfers without CPU intervention - a key capability for low-latency communication in the R5F51405AGFL#30.
How many analog-to-digital converter channels does the R5F51405AGFL#30 provide?
The R5F51405AGFL#30 includes a 12-bit A/D converter (S12ADE) with 11 externally accessible input channels (AD00–AD10). While the RX140 Group's A/D supports up to 18 channels in larger packages, the 48-pin PLQP0048KB-B variant - including the R5F51405AGFL#30 - is limited to these 11 pins. An internal temperature sensor feeds into AD11, but that channel is not brought out to a package pin and thus is not user-accessible on the R5F51405AGFL#30.
Is the R5F51405AGFL#30 equipped with hardware encryption acceleration?
No, the R5F51405AGFL#30 does not include hardware encryption acceleration. Its part number suffix "A" (per Figure 1.1) indicates absence of the AESA (Advanced Encryption Standard Accelerator) and RNGA (True Random Number Generator) modules. These features are only present in "B"-suffix variants (e.g., R5F51405BDFL#30). The R5F51405AGFL#30 retains all other peripherals - including CAN, CTSU2SL, and 12-bit A/D - making it suitable for applications where cryptographic operations are handled in software or offloaded externally.
