Product details
Overview
R5F51403ADNE#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 64 KB flash, 16 KB SRAM, 4 KB data flash, 12-bit A/D converter (11 external channels), and dual 8-bit D/A outputs. It integrates CAN, SCI, I²C, RSPI, capacitive touch sensing (24-key self-capacitance), RTC, low-power timer, and operates from 1.8–5.5 V in industrial temperature range (–40 to +85°C). Used in smart sensors and embedded HMI control nodes.
For engineers reviewing the R5F51403ADNE#30 datasheet, R5F51403ADNE#30 pinout, R5F51403ADNE#30 application, or R5F51403ADNE#30 equivalent, this page delivers verified specifications, package mapping to PWQN0048KC-A (7×7 mm HWQFN, 0.5 mm pitch), validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F51403ADNE#30 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark score at 48 MHz, and on-chip divider completing 32-bit ÷ 32-bit in two cycles. Its memory subsystem includes no-wait-state SRAM and flash with 32 MHz ≤ access, plus background-programmable 4 KB data flash rated for 1M erase/program cycles.
Peripheral integration centers on event-driven operation: ELC enables interrupt-free module triggering (e.g., MTU PWM start via timer event), while CTSU2SL supports 24-key self-capacitance touch sensing without CPU intervention. Clock management includes HOCO (48 MHz ±1%), sub-clock (32.768 kHz), and CAC for real-time oscillator accuracy monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51403ADFL#30 | Same RXv2 core, 64 KB flash, 16 KB SRAM, but in PLQP0048KB-B (7×7 mm LFQFP, 0.5 mm pitch) | Larger footprint (0.5 mm pitch same, but LFQFP has longer leads); no wettable flanks-less suitable for automated optical inspection | Select when existing PCB layout uses LFQFP land pattern or reflow profile excludes QFN thermal pad requirements |
| R5F51403ADFJ#30 | 32-pin variant (PLQP0032GB-A, 7×7 mm LQFP, 0.8 mm pitch) with reduced I/O (23 pins), no CAN, no RTC, and only 8 A/D channels | Lower peripheral count and smaller package-intended for cost-sensitive, space-constrained nodes without time-critical or networked functions | Select only if design eliminates CAN, RTC, and >8 analog inputs; verify pin compatibility and peripheral mapping before migration |
Compared with R5F51403ADNE#30, R5F51403ADFL#30 offers identical functionality in a leaded package for easier prototyping or legacy assembly, while R5F51403ADFJ#30 sacrifices CAN, RTC, and 3 A/D channels to reduce size and cost-making it unsuitable as a drop-in replacement but viable for simplified derivatives.

It provides 16 mailboxes and full protocol handling-including error framing, automatic retransmission, and bus-off recovery-without requiring external transceivers beyond the PHY layer. This capability is confirmed in the R5F51403ADNE#30's peripheral listing on datasheet page 4.
How many analog-to-digital converter channels does the R5F51403ADNE#30 support, and what is its resolution?
The R5F51403ADNE#30 integrates a 12-bit S12ADE A/D converter with 11 external input channels and one internal channel (temperature sensor). Minimum conversion time is 0.67 µs when ADCLK runs at 48 MHz. Each channel supports individually configurable sampling time and disconnection detection. This specification is explicitly stated in Table 1.2 (page 6) and section 35 of the R5F51403ADNE#30 User's Manual.
