For engineers reviewing the R5F526TFCGFM#30 datasheet, R5F526TFCGFM#30 pinout, R5F526TFCGFM#30 application, or R5F526TFCGFM#30 equivalent, key selection considerations include its 100-pin LFQFP package (PLQP0100KB-B), 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit A/D units (up to 7 channels), and Trusted Secure IP Lite with AES-128/256 and true random number generation.

Technical Context

The R5F526TFCGFM#30 implements the RXv3 CPU core with single-cycle instruction execution, 16 general-purpose 32-bit registers, and IEEE 754-compliant single-precision FPU. Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and selectable 16/18/20 MHz HOCO, and PLL for 120 MHz system clock (ICLK), with independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains for peripheral synchronization.

Motor control functionality is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels) and MTU3d (16-bit × 9 channels) support synchronized 3-phase complementary PWM with automatic dead-time insertion; HRPWM provides 260 ps resolution on GPTW0–GPTW3 outputs; S12ADH includes three sample-and-hold units for simultaneous analog acquisition; and ELC allows event-triggered module operation without CPU intervention during sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCGFM#30?

The R5F526TFCGFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 16 general-purpose 32-bit registers, and integrated 32-bit multiplier/divider. The R5F526TFCGFM#30 sustains this speed with no-wait access to both 512 KB code flash and 64 KB SRAM, enabling deterministic real-time motor control loops.

Does the R5F526TFCGFM#30 support CAN FD, and what standard does it comply with?

Yes, the R5F526TFCGFM#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. It includes dedicated TX/RX pins (CAN0TX/CAN0RX), message RAM with configurable mailboxes, and error counters with interrupt reporting. The R5F526TFCGFM#30 requires no external transceiver for physical layer interfacing-only an external CAN bus driver is needed for node connection.

What analog peripherals are included in the R5F526TFCGFM#30, and how many A/D channels support simultaneous sampling?

The R5F526TFCGFM#30 includes three 12-bit A/D units (S12ADH): Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration enables true simultaneous sampling across up to 7 channels-e.g., three phase currents and DC-link voltage-critical for accurate field-oriented control. The R5F526TFCGFM#30 also integrates six analog comparators (CMPCa) and two 12-bit D/A converters usable as reference sources.

What package type and pin count does the R5F526TFCGFM#30 use, and what is its thermal specification?

The R5F526TFCGFM#30 uses the PLQP0100KB-B package: a 100-pin Low-profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. It is rated for the G-version operating temperature range of –40°C to +105°C, making it suitable for under-hood automotive and industrial environments. The R5F526TFCGFM#30's pinout includes dedicated MTU/GPTW I/O, CAN FD, multiple SCI/RSCI, and 82 general-purpose I/Os with 5-V tolerance.

How does the R5F526TFCGFM#30 support IEC60730 functional safety compliance?

The R5F526TFCGFM#30 includes hardware features required for Class B IEC60730 compliance: oscillation-stop detection for main clock failure, A/D converter disconnection detection, independent watchdog timer (IWDT) with window function, memory protection unit (MPU), CRC calculator (CRCA), register write protection, and Trusted Memory (TM) for secure firmware storage. These capabilities reduce software diagnostic overhead and enable systematic hardware-based fault detection-key for certifying R5F526TFCGFM#30-based motor drives in industrial safety applications.
