For engineers reviewing the R5F5651EDGLC#20 datasheet, R5F5651EDGLC#20 pinout, R5F5651EDGLC#20 application, or R5F5651EDGLC#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), -40°C to +85°C temperature grade, dual-bank flash for safe firmware updates, 120-MHz real-time deterministic execution, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.

Technical Context

The R5F5651EDGLC#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) supporting eight configurable regions. Its clock system combines external crystal or internal PLL (up to 120 MHz ICLK), independent PCLKA/PCLKB domains (120/60 MHz), and dedicated IWDT oscillator (120 kHz).

Peripheral subsystems are tightly coupled via Event Link Controller (ELC): 262 interrupt sources feed into ICUB, DMA controllers (DMACAa: 8 ch, EXDMAC: 2 ch, DTCb: 1 ch) manage data movement without CPU intervention, and timer units (MTU3a, TPUa, CMTW) provide synchronized PWM, capture, and RTC-triggered A/D conversion across multiple clock domains.

FAQ

What is the maximum operating frequency and CPU performance of the R5F5651EDGLC#20?

The R5F5651EDGLC#20 operates at a maximum system clock frequency of 120 MHz using the RXv2 core, achieving 240 DMIPS of processing performance. Its single-precision IEEE-754 floating-point unit (FPU) executes math-intensive operations without software emulation, and the 5-stage pipeline with variable-length instructions ensures efficient code density and deterministic timing critical for real-time industrial applications.

Does the R5F5651EDGLC#20 support dual-bank flash for safe firmware updates?

Yes, the R5F5651EDGLC#20 supports dual-bank flash architecture, enabling background programming and seamless firmware updates. One bank can execute code while the other is being reprogrammed, eliminating downtime and ensuring continuous operation-a key requirement for unattended industrial systems. This feature is implemented in hardware and requires no external memory or bootloader complexity.

What graphics capabilities does the R5F5651EDGLC#20 provide for HMI applications?

The R5F5651EDGLC#20 integrates both a Graphic-LCD Controller (GLCDC) and a 2D Drawing Engine (DRW2D). The GLCDC supports 3-plane overlay (background, graphic 1, graphic 2) and multiple pixel formats (32/16/8 bpp), while DRW2D accelerates vector drawing, bit-blitting, rotation, and scaling-enabling responsive GUIs on resolutions up to WVGA without burdening the CPU.

How does the R5F5651EDGLC#20 meet IEC60730 safety requirements for household appliances?

The R5F5651EDGLC#20 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, CRC calculator (8/32-bit), independent watchdog timer (IWDT) with windowing, register write protection, and self-diagnostic A/D functions. These are documented in Renesas' functional safety manual R01US0094EJ0300 and validated for use in certified safety firmware stacks.

What is the package type and pin count of the R5F5651EDGLC#20?

The R5F5651EDGLC#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array (LFBGA) with 24 mm × 24 mm body size and 0.5 mm ball pitch. This package provides 136 general-purpose I/O pins-including 19 with 5-V tolerance-and supports full peripheral access including Ethernet, dual CAN, SD interfaces, and GLCDC signal routing.
