For engineers reviewing the R5F56514FGFB#10 datasheet, R5F56514FGFB#10 pinout, R5F56514FGFB#10 application, or R5F56514FGFB#10 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), -40°C to +105°C G-grade operation, 12-bit dual A/D converter (21-channel unit), 2-channel 12-bit D/A, and TSIP-based secure boot support - all critical for real-time industrial gateway and edge node designs.

Technical Context

The R5F56514FGFB#10 implements the RXv2 CPU core with Harvard CISC architecture, 5-stage pipeline, and variable-length instructions, supporting little- or big-endian data arrangement. Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL for flexible domain-specific clocking: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for ETHERC/DRW2D/GLCDC, and PCLKB up to 60 MHz for most peripherals including S12AD units.

Memory subsystem includes 1.5 MB dual-bank code flash (no-wait ≤50 MHz, 1-wait ≤100 MHz), 32 KB data flash (100,000 write cycles), 640 KB SRAM (no-wait at 120 MHz), and 8 KB standby RAM. Peripheral integration centers on deterministic real-time control: MTU3a (9-channel timer with complementary PWM), TPUa (6-channel), ELC (83-event interlinking), and dedicated DMA controllers (DMACAa: 8 ch, EXDMAC: 2 ch, DTCb: 1 ch) for offloading data movement from CPU.

FAQ

What is the maximum operating frequency and performance rating of the R5F56514FGFB#10?

The R5F56514FGFB#10 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS (Dhrystone MIPS) performance. This is achieved using the RXv2 CPU core with a 5-stage pipeline, single-cycle 32-bit multiplier, and integrated IEEE-754 compliant floating-point unit. The R5F56514FGFB#10 sustains this performance with zero-wait-state access to 640 KB SRAM and optimized flash cache behavior up to 100 MHz.

Does the R5F56514FGFB#10 support secure boot and cryptographic operations?

Yes, the R5F56514FGFB#10 integrates Trusted Secure IP (TSIP) hardware that supports AES-128/192/256 encryption/decryption, SHA-1/SHA-256 hashing, and true random number generation. It enables secure boot via code authentication in the Trusted Memory (TM) region of flash, where instruction fetch is permitted but read-out is blocked - a feature confirmed in the R01DS0276EJ0240 datasheet section 1.1.3.

What are the supported memory configurations for the R5F56514FGFB#10?

The R5F56514FGFB#10 includes 1.5 MB of on-chip code flash memory organized in a dual-bank structure, 32 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), 640 KB of SRAM (256 KB main + 384 KB expansion), and 8 KB of battery-backed standby RAM. Flash access requires zero wait states up to 50 MHz, one wait state up to 100 MHz, and two wait states above 100 MHz - all verified in Table 1.1 of the R01DS0276EJ0240 datasheet.

Which communication interfaces are integrated into the R5F56514FGFB#10?

The R5F56514FGFB#10 integrates Ethernet MAC (10/100 Mbps MII/RMII), CAN 2.0B (2 channels, 32 mailboxes each), SD host/slave interfaces (SDHI/SDSI), quad SPI (QSPI), three RSPI channels, three I²C channels (RIIC), 13 SCI channels (SCIg/h/i), USB 2.0 FS host/function/OTG, and MMCIF. These are explicitly listed in the "Various communications interfaces" section of the R01DS0276EJ0240 datasheet Rev.2.40.

What is the package type and pin count of the R5F56514FGFB#10?

The R5F56514FGFB#10 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm ball pitch. It is rated for the industrial G-grade temperature range of –40°C to +105°C. This package mapping is confirmed in the "Package Information" section of the R01DS0276EJ0240 datasheet and Renesas' official part numbering guide.
