Renesas R5F526TBCGFN#50

Overview

R5F526TBCGFN#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM with dead-time control - deployed in industrial HVAC compressors and servo drives.

For engineers reviewing the R5F526TBCGFN#50 datasheet, R5F526TBCGFN#50 pinout, R5F526TBCGFN#50 application, or R5F526TBCGFN#50 equivalent, key selection criteria include its 120 MHz GPTWa timer with 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, IEC60730-compliant self-test features, and 100-pin LFQFP package supporting 82 general-purpose I/O pins with 5-V tolerance and programmable drive strength.

Technical Context

The R5F526TBCGFN#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in real-time motor control loops. Its clock system integrates PLL with external 8–24 MHz crystal support, internal 240 kHz LOCO and selectable 16/18/20 MHz HOCO, and dedicated 120 kHz IWDT oscillator.

Peripheral coordination is managed via Event Link Controller (ELC), enabling 183 internal event signals to trigger timer starts/stops, A/D conversion triggers, or port output changes without CPU intervention - critical for deterministic timing in field-oriented control (FOC) algorithms using simultaneous sampling across three 12-bit S12ADH units.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCGFN#50?

The R5F526TBCGFN#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency in real-world embedded workloads, including motor control algorithms and communication stack processing. The R5F526TBCGFN#50 sustains this performance with zero wait-state access to both 512 KB code flash and 64 KB SRAM, making it suitable for demanding real-time applications.

Does the R5F526TBCGFN#50 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBCGFN#50 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps in FD mode. It includes dedicated TXD/RXD pins (CTX0/CRX0), built-in message RAM, and error counters - enabling robust communication in industrial networks and automotive subsystems. The R5F526TBCGFN#50 requires an external CAN transceiver for physical layer interfacing.

How many A/D converter channels does the R5F526TBCGFN#50 support, and what is their architecture?

The R5F526TBCGFN#50 includes three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 configurable inputs. Each unit features dedicated sample-and-hold circuits (3 per unit for Units 0/1), programmable sampling time per channel, and simultaneous trigger capability via ELC-linked timers. This architecture enables true simultaneous sampling across multiple current/voltage sensors - a critical requirement for accurate field-oriented control in the R5F526TBCGFN#50.

What package type and pin count does the R5F526TBCGFN#50 use?

The R5F526TBCGFN#50 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 × 14 mm body size, 0.5 mm pitch, and exposed thermal pad. It provides 82 general-purpose I/O pins with 5-V tolerance, open-drain capability, and programmable drive strength - optimized for noise-immune motor control board layouts. The R5F526TBCGFN#50's pinout is documented in Section 1.2 of the R01DS0407EJ0120 datasheet.

Does the R5F526TBCGFN#50 include hardware security features for firmware protection?

Yes, the R5F526TBCGFN#50 incorporates Trusted Secure IP Lite, including AES-128/256 encryption engines (ECB/CBC/GCM), true random number generator, and Trusted Memory (TM) functionality. TM restricts code flash read access to CPU instruction fetch only, preventing unauthorized firmware extraction. Additionally, register write protection and MPU guard critical system registers and memory regions - collectively supporting IEC60730 Class B and basic functional safety requirements in the R5F526TBCGFN#50.
