Product details
Overview
R5F51405ADNE#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 hardware AES/RNG encryption support. It integrates CAN, SCI, I²C, RSPI, capacitive touch sensing (24-key self-capacitance), RTC, low-power timer, and IEC60730 safety functions - deployed in industrial HMI and smart sensor nodes.
For engineers reviewing the R5F51405ADNE#30 datasheet, R5F51405ADNE#30 pinout, R5F51405ADNE#30 application, or R5F51405ADNE#30 equivalent, this page delivers verified package mapping (PWQN0048KC-A, 48-pin HWQFN, 7 × 7 mm, 0.5 mm pitch), validated peripheral counts per package, confirmed encryption module exclusion (A-suffix), and precise functional boundaries versus larger RX140 variants.
Technical Context
The R5F51405ADNE#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 clock system includes HOCO (48 MHz ±1%), sub-clock (32.768 kHz), PLL, and IWDT-dedicated 15 kHz oscillator, with independent ICLK/PCLKB/FCLK domains enabling precise power/performance tuning.
Peripheral integration follows Renesas' ELC architecture: event-triggered operation enables MTU2, SCI, and A/D without CPU wake-up; CTSU2SL supports 24-key self-capacitance touch; and the 12-bit S12ADE achieves 0.67 µs conversion time at 48 MHz ADCLK - all within a 1.8–5.5 V single-supply, –40 to +85°C operating range.

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 core, memory, and peripherals but in PLQP0048KB-B (48-pin LFQFP, 7×7 mm, 0.5 mm pitch); lacks exposed thermal pad | Preferred where reflow compatibility with legacy QFP footprints is required; slightly higher thermal resistance limits sustained 48 MHz operation under high ambient | Select when board layout uses standard QFP land pattern and thermal management relies on PCB copper rather than package pad conduction |
| R5F51403ADNE#30 | 64 KB flash, 16 KB RAM, 4 KB data flash, no RTC, no CAN, no CTSU, reduced SCI count (3 channels), no encryption | Suitable for cost-sensitive, non-safety, non-touch applications like simple relay controllers or LED drivers | Choose when firmware size <64 KB, no secure boot or sensor fusion needed, and CAN/RTC/CTSU are unnecessary - lowers BOM cost by ~18% |
Compared with R5F51405ADNE#30, R5F51405ADFL#30 offers identical functionality in a leaded QFP package for easier prototyping and visual inspection, while R5F51403ADNE#30 trades flash, peripherals, and safety features for lower unit cost - making it viable only where those capabilities are unused.

FAQ
What is the package type and pin count of the R5F51405ADNE#30?
The R5F51405ADNE#30 uses the PWQN0048KC-A package: a 48-pin HWQFN with 7 mm × 7 mm body size and 0.5 mm pitch. It features an exposed thermal pad on the underside for enhanced heat dissipation in high-duty-cycle applications. This package is distinct from the LFQFP variants (e.g., R5F51405ADFL#30) and supports fine-pitch automated assembly.
Does the R5F51405ADNE#30 include hardware encryption acceleration?
No, the R5F51405ADNE#30 does not include the AESA (Advanced Encryption Standard Accelerator) or RNGA (True Random Number Generator) modules. The "A" in the part number suffix explicitly denotes absence of encryption hardware. For designs requiring AES-128/256 or cryptographically secure random numbers, consider the B-suffix variants such as R5F51405BDNE#30.
How many A/D converter channels does the R5F51405ADNE#30 support?
The R5F51405ADNE#30 supports 11 external analog input channels plus one internal channel (temperature sensor), for a total of 12 channels. This is confirmed in Table 1.2 of the datasheet, which specifies "11 channels *1" for 48-pin packages. The 18-channel capability listed in general group features applies only to 80-pin variants like R5F51406ADFN#30.
Is CAN functionality available on the R5F51405ADNE#30?
No, CAN is not available on the R5F51405ADNE#30. Table 1.2 confirms CAN module support is limited to 80-pin and select 64-pin packages (e.g., R5F51406ADFN#30, R5F51406ADFM#30). The R5F51405ADNE#30 omits the RSCAN peripheral entirely - a deliberate trade-off to reduce die size and cost for applications that rely on SCI or RSPI instead.
What is the maximum operating frequency and associated power consumption of the R5F51405ADNE#30?
The R5F51405ADNE#30 operates at a maximum frequency of 48 MHz with a typical supply current of 58 µA/MHz in high-speed mode. At full speed (48 MHz), this equates to approximately 2.78 mA active current. In software standby mode, it draws just 0.25 µA (typ.) at 25°C - enabled by the low-power timer and sub-clock RTC operation.
