Renesas R5F566TEAGFF#10

Overview

R5F566TEAGFF#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, operating at up to 160 MHz with 1 MB code flash, 128 KB SRAM, 32 KB data flash, integrated 3-phase/5-phase PWM timers (GPTW/MTU3), 12-bit A/D converter with simultaneous sampling across three units (30 channels total), and on-chip TSIP-Lite encryption. It targets real-time motor drive systems requiring precise timing, safety compliance (IEC60730), and USB/CAN connectivity.

For engineers reviewing the R5F566TEAGFF#10 datasheet, R5F566TEAGFF#10 pinout, R5F566TEAGFF#10 application, or R5F566TEAGFF#10 equivalent, key selection considerations include its 144-pin LFQFP package with 110 GPIOs (4× 5-V tolerant), 195-ps HRPWM resolution, dual 12-bit DAC outputs usable as comparator references, and support for IEC60730 self-test functions including oscillation-stop detection and RAM ECC.

Technical Context

The R5F566TEAGFF#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and configurable endianness. Its clock system integrates PLL, high-speed on-chip oscillator (16–20 MHz), and independent IWDT-dedicated 120-kHz oscillator - enabling deterministic real-time response in motor control loops.

Peripheral coordination is managed via Event Link Controller (ELC), allowing 188 internal event signals (e.g., timer overflows, ADC completions) to trigger module actions without CPU intervention - critical for low-latency PWM dead-time compensation, synchronous A/D triggering, and fault-safe output disable during short-circuit detection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F566TEAGFF#10?

The R5F566TEAGFF#10 operates at a maximum frequency of 160 MHz and achieves 928 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 8-KB ROM cache, and zero-wait-state access to 128 KB SRAM - enabling tight motor control loops with sub-microsecond jitter. The R5F566TEAGFF#10 maintains this speed across its full industrial temperature range (–40°C to +105°C).

Does the R5F566TEAGFF#10 support simultaneous sampling across all 30 A/D channels?

No - the R5F566TEAGFF#10 supports simultaneous sampling only within each of its three independent S12ADH units: Unit 0 (8 channels, 3 sample-and-hold circuits), Unit 1 (8 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels, no shared sample-and-hold). While all 30 channels can be scanned in sequence, true simultaneous capture is limited to up to 7 channels across Units 0 and 1 when configured for group-triggered acquisition. The R5F566TEAGFF#10 uses hardware event linking to synchronize triggers between units for coordinated multi-axis current sensing.

What safety certifications and self-test features does the R5F566TEAGFF#10 include for IEC60730 compliance?

The R5F566TEAGFF#10 includes dedicated hardware for IEC60730 Class B compliance: oscillation-stoppage detection for main clock, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test-assisting function via DOC, analog comparator disconnection detection, and register write protection. These features are implemented in silicon - not software libraries - and require no external components. The R5F566TEAGFF#10 also supports Trusted Memory (TM) to protect critical bootloader code in flash blocks 8–9.

Can the R5F566TEAGFF#10 generate 5-phase complementary PWM waveforms, and how many output channels does it support?

Yes - the R5F566TEAGFF#10's 32-bit GPTW timer supports 5-phase complementary PWM mode with two dedicated output channels (GTIOCA0/GTIOCB0 and GTIOCA1/GTIOCB1), providing non-overlapping waveforms with hardware-configurable dead time. This mode is optimized for 5-phase BLDC motors used in high-efficiency fans and pumps. The R5F566TEAGFF#10 also supports 10-channel single-phase and 3-channel 3-phase complementary PWM simultaneously, enabling multi-motor control on a single chip.

What is the purpose of the 16 KB SRAM with ECC in the R5F566TEAGFF#10, and where is it mapped in memory?

The 16 KB SRAM with SEC-DED (single error correction/double error detection) ECC in the R5F566TEAGFF#10 is mapped to address range 00FF_C000h–00FF_FFFFh and is intended for storing safety-critical variables, control algorithm coefficients, and fault logs. Unlike the main 128 KB SRAM, this block performs automatic error correction on read access and detects uncorrectable errors - meeting ASIL-B-equivalent reliability requirements. The R5F566TEAGFF#10 initializes this region at boot and reports ECC faults via dedicated interrupt vectors to enable fail-safe shutdown.
