Product details
Overview
R5F5671CHGBP#20 from Renesas is a 120-MHz 32-bit RXv3 microcontroller with double-precision IEEE-754 FPU, 2-MB on-chip code flash (dual-bank), 384-KB SRAM, and integrated capacitive touch sensing unit. It supports CAN 2.0B (2 channels), USB 2.0 FS host/function/OTG, SDHI, QSPIX, and 12-bit A/D converters - deployed in industrial HMI and smart appliance control systems.
For engineers reviewing the R5F5671CHGBP#20 datasheet, R5F5671CHGBP#20 pinout, R5F5671CHGBP#20 application, or R5F5671CHGBP#20 equivalent, key selection criteria include its 145-pin TFLGA (0.65-mm pitch) package, -40°C to +105°C G-grade temperature rating, TSIP-based AES256/SHA256 encryption, and IEC60730-compliant self-test features for functional safety-critical firmware.
Technical Context
The R5F5671CHGBP#20 implements the RXv3 CPU core with 113 instructions, 16 general-purpose 32-bit registers, and dual-precision floating-point coprocessor supporting 21 FP64 instructions. Its memory subsystem includes 2-MB code flash with ROM cache (8 KB), zero-wait access up to 60 MHz, and background programming/erasing capability.
Peripheral integration centers on deterministic real-time control: MTU3a (9-channel 16/32-bit timer), TPUa (6-channel 16-bit PWM), CMTW (2×32-bit compare-match timers), and ELC-driven event linking across 99 internal signals - enabling hardware-synchronized sensor sampling, motor commutation, and secure boot sequence execution without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F5671EHGBP#20 | Same RX671 Group silicon, but 145-pin TFLGA-0.50mm pitch (7 × 7 mm); 113 GPIOs vs. 111; identical peripherals and memory. | Smaller footprint suits space-constrained designs; requires PCB redesign due to different pitch and pin assignment. | Select when board area is constrained and 0.50-mm assembly capability exists. |
| R5F566TEHDFP#30 | RX66T Group part: 160-MHz CPU, no TSIP, no CTSU, 1.5-MB flash, 256-KB SRAM, 100-pin LQFP. | Targeted at motor control only; lacks USB, SDHI, QSPIX, and security features - unsuitable for HMI or secure gateway use cases. | Consider only for cost-sensitive motor drive applications where encryption and touch are unnecessary. |
Compared with R5F5671EHGBP#20, the R5F5671CHGBP#20 offers larger PCB real estate margin and simplified 0.65-mm pitch assembly, while R5F566TEHDFP#30 trades security and connectivity for raw motor-control throughput - making the R5F5671CHGBP#20 optimal for integrated HMI+control+security applications.
