For engineers reviewing the R5F51405BGFM#30 datasheet, R5F51405BGFM#30 pinout, R5F51405BGFM#30 application, or R5F51405BGFM#30 equivalent, this page delivers verified package mapping (PLQP0064KB-C, 64-pin LFQFP, 10 × 10 mm, 0.5 mm pitch), confirmed low-power modes (0.25 µA standby), real-time clock support, capacitive touch sensing (32 keys), and encryption-ready AES-128/256 hardware acceleration.
Technical Context
The R5F51405BGFM#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, 204 CoreMark @ 48 MHz, and IEEE-754-compliant 32-bit FPU. Its clock system integrates HOCO (48 MHz ±1%), sub-clock oscillator (32.768 kHz), PLL, and CAC for frequency accuracy validation.
Peripheral coordination is managed via Event Link Controller (ELC) enabling interrupt-free module triggering and linked operation during CPU sleep. The MCU supports IEC60730 Class B compliance through self-diagnostic A/D, RAM test assistance, IWDT, and clock monitoring functions.

FAQ
What is the maximum operating frequency and core type of the R5F51405BGFM#30?
The R5F51405BGFM#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark at that speed and includes an IEEE-754-compliant 32-bit floating-point unit. The core uses a 5-stage pipeline Harvard architecture with variable-length instructions and supports both little-endian and big-endian data arrangement.
Does the R5F51405BGFM#30 include hardware encryption capabilities?
Yes, the R5F51405BGFM#30 includes an Advanced Encryption Standard hardware accelerator (AESA) supporting AES-128 and AES-256 in ECB, CBC, and CTR modes, plus a True Random Number Generator (RNGA). These are enabled by the "B" suffix in the part number and are absent in "A"-suffix variants like R5F51405ADFM#30.
What package type and pin count does the R5F51405BGFM#30 use?
The R5F51405BGFM#30 uses the PLQP0064KB-C package: a 64-pin Low-Profile Quad Flat Package with 10 × 10 mm body size and 0.5 mm pitch. This is confirmed in Table 1.3 and Figure 1.1 of the datasheet, where "FM" denotes LFQFP/64/0.50.
How many A/D and D/A channels does the R5F51405BGFM#30 support?
The R5F51405BGFM#30 integrates a 12-bit A/D converter (S12ADE) with 15 external input channels and one internal channel (temperature sensor), plus two independent 8-bit D/A converter channels. These are fully functional in the 64-pin variant per Table 1.2, unlike smaller-package versions which omit D/A or reduce A/D count.
Is CAN functionality available on the R5F51405BGFM#30, and what standard does it meet?
Yes, the R5F51405BGFM#30 includes one CAN module (RSCAN) compliant with ISO11898-1, supporting both standard and extended frames at up to 1 Mbps. CAN is present in all 64-pin and 80-pin RX140 variants, including this part, and requires only an external transceiver for physical layer implementation.
