Renesas R5F51406AGFL#10

Overview

R5F51406AGFL#10 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 256 KB flash, 64 KB SRAM, 8 KB data flash, on-chip FPU, 12-bit A/D converter (11 external channels), two 8-bit D/A channels, CAN 2.0B interface, and capacitive touch sensing (24-key self-capacitance). It targets industrial control panels requiring real-time responsiveness, low-power operation, and secure firmware updates.

For engineers reviewing the R5F51406AGFL#10 datasheet, R5F51406AGFL#10 pinout, R5F51406AGFL#10 application, or R5F51406AGFL#10 equivalent, key selection criteria include its 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), –40 to +105°C temperature grade, integrated AES/RNG encryption, and support for IEC60730 Class B compliance in safety-critical embedded systems.

Technical Context

The R5F51406AGFL#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 204 CoreMark at 48 MHz. Its on-chip FPU complies with IEEE-754 single-precision, and the 32-bit hardware divider executes in two clock cycles.

It integrates event-driven peripheral coordination via the Event Link Controller (ELC), allowing timer-triggered A/D conversion or PWM updates without CPU intervention. The Realtime Clock (RTCB) is omitted in this 48-pin variant per Table 1.2, while the Low Power Timer (LPTa) remains active during software standby mode with 6.2 µs wake-up latency.

FAQ

What is the maximum operating frequency and core type of the R5F51406AGFL#10?

The R5F51406AGFL#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 a 5-stage pipeline, variable-length instruction set, and on-chip FPU compliant with IEEE-754 single-precision. This enables deterministic real-time execution for industrial control tasks while maintaining code density.

Does the R5F51406AGFL#10 support hardware encryption and random number generation?

Yes, the R5F51406AGFL#10 integrates an Advanced Encryption Standard (AES) hardware accelerator supporting 128- and 256-bit keys in ECB, CBC, and CTR modes, plus a True Random Number Generator (RNGA) producing 32-bit values. These are enabled by the 'G' (high-temp) and 'B' (encryption) suffixes in the part numbering scheme-confirmed in Table 1.3 of the datasheet.

How many analog-to-digital input channels does the R5F51406AGFL#10 provide, and what is its resolution?

The R5F51406AGFL#10 includes a 12-bit S12ADE A/D converter with 11 external input channels (AD00–AD10) and one internal channel (temperature sensor). Minimum conversion time is 0.67 µs at 48 MHz ADCLK, and each channel supports independent sampling time configuration and analog input disconnection detection.

What communication interfaces are integrated into the R5F51406AGFL#10?

The R5F51406AGFL#10 integrates one CAN 2.0B module (1 Mbps), five SCI channels (asynchronous/clock-sync/Smart Card), one I2C bus interface (RIICa, 400 kbps), and one RSPI channel (16 Mbps). It does not include RTCB or CTSU2L in this 48-pin variant, but retains CTSU2SL for 24-key capacitive touch sensing.

What is the package type and thermal specification of the R5F51406AGFL#10?

The R5F51406AGFL#10 uses the PLQP0048KB-B package: a 48-pin LFQFP with 7 × 7 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for –40 to +105°C operating temperature ('G' grade), making it suitable for under-hood automotive auxiliary modules and industrial environments with elevated ambient temperatures.
