Product details
Overview
R5F56517BGFB#10 from Renesas is a 32-bit RXv2 microcontroller with 120 MHz CPU frequency, 240 DMIPS performance, single-precision IEEE-754 FPU, 2 MB on-chip code flash memory, and 640 KB SRAM. It integrates Ethernet MAC, dual CAN channels, SD host/slave interfaces, QSPI, GLCDC, DRW2D, and hardware AES encryption - designed for industrial HMI, networked gateway, and secure IoT edge devices.
For engineers reviewing the R5F56517BGFB#10 datasheet, R5F56517BGFB#10 pinout, R5F56517BGFB#10 application, or R5F56517BGFB#10 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), -40°C to +105°C operating range (G-version), dual-bank flash for safe firmware updates, 136 GPIOs with 5-V tolerance, and integrated real-time clock with battery backup support.
Technical Context
The R5F56517BGFB#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-based memory protection. Its clock system combines external crystal oscillation (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO/HOCO/IWDT-dedicated) to drive independent peripheral clocks - PCLKA up to 120 MHz for ETHERC/DRW2D/AES, PCLKB up to 60 MHz for timers and ADC.
It features three DMA controllers (DMACAa: 8 channels, EXDMAC: 2 channels, DTCb: 1 channel), event-linking capability across 83 internal signals, and safety-oriented peripherals including CRC calculator (CRCA), register write protection, and IEC60730-compliant self-diagnostic A/D converter.
