For engineers reviewing the R5F56514EDFB#10 datasheet, R5F56514EDFB#10 pinout, R5F56514EDFB#10 application, or R5F56514EDFB#10 equivalent, key selection criteria include its 176-pin LFBGA package with 136 GPIOs, dual-bank flash for safe firmware updates, integrated GLCDC + DRW2D for embedded graphics, and IEC60730-compliant safety features including CRC, IWDT, and register write protection.

Technical Context

The R5F56514EDFB#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code density. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent PCLK domains (PCLKA up to 120 MHz for ETHERC/DRW2D, PCLKB up to 60 MHz for timers/A/D).

It supports deterministic real-time operation via Event Link Controller (ELC) for hardware-triggered peripheral chaining, eliminating CPU intervention for time-critical sequences such as PWM-triggered A/D conversion or RTC event capture. Safety is enforced by MPU (8 regions), Trusted Memory (TM) for code protection, and self-diagnostic A/D with internal reference generation.

FAQ

What is the maximum operating frequency and CPU performance of the R5F56514EDFB#10?

The R5F56514EDFB#10 operates at a maximum frequency of 120 MHz using the RXv2 32-bit CPU core, delivering 240 DMIPS of processing performance. Its Harvard architecture with 5-stage pipeline and variable-length instruction set enables efficient code execution, while the integrated single-precision IEEE-754 floating-point unit supports real-time mathematical computation without software emulation overhead. This performance level is sustained across all on-chip peripherals due to the multi-bus architecture and zero-wait-state SRAM.

Does the R5F56514EDFB#10 support secure firmware updates and cryptographic operations?

Yes, the R5F56514EDFB#10 includes hardware-accelerated AES-128/192/256 encryption, Trusted Secure IP (TSIP), and a programmable CRC calculator supporting multiple polynomials for 8- and 32-bit data. Its dual-bank flash architecture enables background programming and atomic bank switching - allowing verified firmware images to be written while the active bank continues execution. Combined with register write protection and MPU-enforced memory isolation, these features satisfy IEC60730 Class B requirements for secure, fail-safe updates.

What display interfaces and graphics capabilities does the R5F56514EDFB#10 provide?

The R5F56514EDFB#10 integrates a Graphic-LCD Controller (GLCDC) supporting 3-layer overlay (background + two graphics planes) and a 2D Drawing Engine (DRW2D) for hardware-accelerated vector drawing, bit blitting, rotation, and stretching. It supports 32/16/8 bpp pixel formats and CLUT-based color lookup tables, enabling direct drive of monochrome or color STN/TFT panels up to VGA resolution. These blocks operate independently of the CPU, freeing it for application logic while maintaining smooth UI rendering.

How many communication interfaces does the R5F56514EDFB#10 include, and which are supported simultaneously?

The R5F56514EDFB#10 integrates Ethernet MAC (10/100 Mbps MII/RMII), two independent CAN 2.0B controllers (32 mailboxes each), three RSPI channels, three I²C interfaces (one supporting 1 Mbps fast-mode plus), one QSPI, one SD host interface (25 MB/s), one SD slave interface, and one MMCIF. All interfaces operate concurrently under independent clock domains (PCLKA/PCLKB), with dedicated DMA channels (DMACAa, EXDMAC, DTCb) ensuring zero-CPU-load data movement - essential for multi-protocol industrial gateways.

What is the package type and pin count of the R5F56514EDFB#10, and what I/O features does it offer?

The R5F56514EDFB#10 uses a PLBG0176GA-A 176-pin LFBGA package (13 mm × 13 mm, 0.8 mm pitch) with 136 general-purpose I/O pins. Each pin supports 5-V tolerance, programmable pull-up resistors, open-drain output, and configurable drive strength. The I/O subsystem includes event linking for hardware-triggered peripheral coordination, and dedicated pins for Ethernet, CAN, SD, and external bus expansion - making it ideal for compact, high-density industrial control boards requiring robust interfacing.
