Renesas R5F526TFCGND#30

Overview

R5F526TFCGND#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and high-resolution PWM with 260 ps timing resolution. It supports IEC60730 functional safety compliance and operates across –40°C to +105°C.

For engineers reviewing the R5F526TFCGND#30 datasheet, R5F526TFCGND#30 pinout, R5F526TFCGND#30 application, or R5F526TFCGND#30 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 3-phase/5-phase complementary PWM generation, simultaneous sampling across three 12-bit A/D units, and Trusted Secure IP Lite encryption support.

Technical Context

The R5F526TFCGND#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at up to 60–120 MHz).

Motor control capability is anchored by GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel, 260 ps resolution), all synchronized via PCLKC and coordinated through ELC event linking - allowing hardware-triggered A/D conversion start, dead-time insertion, and phase-counting without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCGND#30?

The R5F526TFCGND#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under those conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all verified in the official R01DS0407EJ0120 Rev.1.20 datasheet. The R5F526TFCGND#30 sustains this speed across its full 2.7–5.5 V supply range and –40°C to +105°C temperature envelope.

Does the R5F526TFCGND#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TFCGND#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, A/D converter disconnection monitoring, clock accuracy measurement circuit, independent watchdog timer (IWDT) with window function, RAM test-assisting function via DOC, and CRCA for data integrity. These are documented in Section 1.1 and Section 23 of the R01DS0407EJ0120 Rev.1.20 datasheet and require no external components to implement baseline self-test routines for the R5F526TFCGND#30.

What PWM configurations does the R5F526TFCGND#30 support for 3-phase motor control?

The R5F526TFCGND#30 supports 3-phase complementary PWM in both MTU3d (9-channel, 16-bit) and GPTWa (8-channel, 32-bit) timers, with automatic dead-time insertion and non-overlapping waveform generation. It also provides 5-phase complementary PWM (2 channels) and single-phase complementary PWM (10 channels). All modes are hardware-coordinated via ELC and support synchronous start/stop - confirmed in Tables 1.1 and 13.1 of the R01DS0407EJ0120 Rev.1.20 datasheet for the R5F526TFCGND#30.

How many A/D converter channels does the R5F526TFCGND#30 have, and what is their sampling capability?

The R5F526TFCGND#30 includes three 12-bit A/D converter units (S12ADH): Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 configurable inputs. Each unit supports simultaneous sampling, with minimum conversion time of 0.9 µs per channel when ADCLK runs at 60 MHz. This architecture is explicitly specified for "products with 64 Kbytes of RAM" - matching the R5F526TFCGND#30's memory configuration per Table 1.2 in R01DS0407EJ0120 Rev.1.20.

Is the R5F526TFCGND#30 pin-compatible with other RX26T group MCUs in the same package?

Yes, the R5F526TFCGND#30 is pin-compatible with other 100-pin LFQFP variants in the RX26T Group, including R5F526TDDGND#30 and R5F526TEAGND#30, sharing identical PLQP0100KB-B footprint, power/ground pinout, and peripheral signal assignments. Differences are limited to memory size and feature enablement - confirmed in Table 1.2 ("Comparison of Functions for Different Packages") of the R01DS0407EJ0120 Rev.1.20 datasheet for the R5F526TFCGND#30.
