Overview

R5F51403AGFL#10 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), 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 across –40 to +105°C.

For engineers reviewing the R5F51403AGFL#10 datasheet, R5F51403AGFL#10 pinout, R5F51403AGFL#10 application, or R5F51403AGFL#10 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/power/communication parameters for industrial control, sensor hubs, and embedded HMI systems.

Technical Context

The R5F51403AGFL#10 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark @ 48 MHz, and on-chip divider (2-cycle latency). Its clock system integrates HOCO (48 MHz ±1%), sub-clock oscillator (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.

Peripheral integration includes ELC for event-driven module activation without CPU wake-up, DTC for five transfer modes, MTU2a (6-channel 16-bit timer with complementary PWM), and CTSU2SL supporting 24-key self-capacitance touch - all mapped to its 48-pin LFQFP (PLQP0048KB-B) package with 0.5 mm pitch and 7 × 7 mm footprint.

FAQ

What is the maximum operating frequency and core type of the R5F51403AGFL#10?

The R5F51403AGFL#10 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark at this speed and includes an IEEE-754-compliant 32-bit floating-point unit. The core uses a CISC Harvard architecture with a 5-stage pipeline and variable-length instructions, enabling efficient code density and real-time deterministic execution for the R5F51403AGFL#10.

Which package and pin count does the R5F51403AGFL#10 use?

The R5F51403AGFL#10 uses the PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package with 7 × 7 mm body size and 0.5 mm lead pitch. This package includes an exposed thermal pad and supports reflow soldering. All 48 pins are electrically assigned per the official Renesas pin function table, and the R5F51403AGFL#10 shares this footprint with other RX140 48-pin variants like R5F51405AGFL#30.

Does the R5F51403AGFL#10 include a real-time clock (RTC) module?

No, the R5F51403AGFL#10 does not include a real-time clock (RTCB) module. According to Table 1.2 in the RX140 datasheet, RTC is only available in 80-pin and certain 64-pin packages - not in the 48-pin configuration used by the R5F51403AGFL#10. Designs requiring calendar timekeeping must use an external RTC or select a higher-pin-count variant such as R5F51405AGFM#30. This limitation applies specifically to the R5F51403AGFL#10.

How many analog-to-digital converter (A/D) input channels does the R5F51403AGFL#10 support?

The R5F51403AGFL#10 supports 11 external analog input channels plus one internal channel (temperature sensor) for its 12-bit S12ADE A/D converter. This count is confirmed in Table 1.2 for 48-pin products with 64 KB ROM. Each channel allows independent sampling time configuration, and the module supports conversion start via software, timer, or ELC events - all fully implemented in the R5F51403AGFL#10.

What communication interfaces are integrated into the R5F51403AGFL#10?

The R5F51403AGFL#10 integrates one CAN 2.0B module (ISO11898-1, 1 Mbps), five SCI channels (including LIN support on SCI12), one I²C bus interface (RIICa, 400 kbps), and one RSPI channel (16 Mbps). It does not include Ethernet, USB, or SDIO. These interfaces are fully routed to dedicated pins in the 48-pin LFQFP package and are documented in the R5F51403AGFL#10 datasheet sections covering SCIg, SCIh, RIICa, and RSCAN.
