Product details
Overview
R5F5651EHDFB#10 from Renesas is a 120-MHz 32-bit RXv2 core MCU with single-precision IEEE-754 FPU, 240 DMIPS performance, 2 MB on-chip code flash (dual-bank), 640 KB SRAM, and integrated Ethernet MAC, CAN, SD host/slave, QSPI, GLCDC, DRW2D, and TSIP encryption. It targets industrial HMI, networked gateways, and secure IoT edge controllers requiring real-time deterministic execution and rich peripheral integration.
For engineers reviewing the R5F5651EHDFB#10 datasheet, R5F5651EHDFB#10 pinout, R5F5651EHDFB#10 application, or R5F5651EHDFB#10 equivalent, key selection criteria include its 176-pin LFBGA package, -40°C to +85°C operating range, 120 MHz system clock synchronized with PCLKA, dual-bank flash for safe firmware updates, and hardware-accelerated AES/TSIP for secure boot and data protection.
Technical Context
The R5F5651EHDFB#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-enforced memory protection. Its CPU executes 32-bit multiply in one cycle and division in two cycles, supports little/big-endian data, and delivers 240 DMIPS at 120 MHz using on-chip FPU and dual MAC units.
Peripheral clock domains are strictly partitioned: ICLK up to 120 MHz drives the CPU; PCLKA (up to 120 MHz) clocks ETHERC, EDMAC, AES, GLCDC, and DRW2D; PCLKB (up to 60 MHz) serves TPU, MTU3, SCI, and A/D converters; PCLKC/PCLKD (up to 60 MHz) drive S12AD units independently. This enables concurrent high-speed communication, graphics rendering, and analog acquisition without contention.

FAQ
What is the maximum system clock frequency supported by the R5F5651EHDFB#10?
The R5F5651EHDFB#10 supports a maximum system clock (ICLK) frequency of 120 MHz, achieved using the on-chip PLL with an external 8–24 MHz crystal or internal HOCO. At this speed, the CPU delivers 240 DMIPS and the PCLKA domain (driving Ethernet MAC, GLCDC, and DRW2D) also operates at 120 MHz, enabling real-time multimedia and network processing without bottlenecks.
Does the R5F5651EHDFB#10 include hardware cryptographic acceleration?
Yes, the R5F5651EHDFB#10 integrates dedicated hardware blocks for AES encryption/decryption (128/192/256-bit keys) and the Trusted Secure IP (TSIP) engine, which accelerates secure boot, key generation, and TLS handshake operations. These features eliminate software-based crypto overhead and meet IEC 60730 Class B requirements for secure firmware validation in the R5F5651EHDFB#10.
What package type and pin count does the R5F5651EHDFB#10 use?
The R5F5651EHDFB#10 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm body size and 0.5-mm pitch. It provides 136 general-purpose I/O pins (19 of which are 5-V tolerant), supporting complex peripheral routing for Ethernet, CAN, SD, and parallel LCD interfaces in space-constrained industrial designs.
Can the R5F5651EHDFB#10 operate in low-power modes while maintaining RTC and backup RAM functionality?
Yes, the R5F5651EHDFB#10 supports four low-power modes including deep software standby, where the RTC continues counting from VBATT backup power and 8 KB of standby RAM retains data. During deep standby, only the IWDT and RTC remain active, drawing minimal current-enabling battery-backed operation for years in metering or alarm systems using the R5F5651EHDFB#10.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F5651EHDFB#10?
The ELC in the R5F5651EHDFB#10 enables direct hardware-level chaining of 83 internal events-such as MTU3 timer overflow triggering S12AD conversion, which then initiates DMACA transfer to SRAM-without CPU intervention or ISR latency. This deterministic signal routing reduces jitter in time-critical control loops and improves throughput in data acquisition systems built around the R5F5651EHDFB#10.
