Product details
Overview
R5F566NNHGFB#10 from Renesas is a 32-bit RXv3 microcontroller operating at 120 MHz, featuring double-precision IEEE-754 FPU, 2 MB on-chip code flash, 1 MB SRAM (including 32 KB ECC RAM), and integrated Ethernet MAC, CAN, USB 2.0 FS, SDHI, and GLCDC - designed for industrial HMI, networked gateway, and real-time control applications requiring deterministic timing and functional safety support.
For engineers reviewing the R5F566NNHGFB#10 datasheet, R5F566NNHGFB#10 pinout, R5F566NNHGFB#10 application, or R5F566NNHGFB#10 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-C), dual-bank flash architecture enabling background programming, IEC60730-compliant self-test features, and hardware-accelerated 2D graphics rendering via DRW2D engine.
Technical Context
The R5F566NNHGFB#10 implements the RXv3 CPU core with 698 CoreMark performance at 120 MHz, supporting little-endian data and single/double-precision IEEE-754 floating-point arithmetic. It integrates a memory protection unit (MPU), collective register bank save function, and JTAG/FINE debugging interfaces for secure, deterministic embedded execution.
Its clock system combines external crystal oscillation (8–24 MHz), PLL synthesis, and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated 120 kHz), enabling independent domain clocking: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, GLCDC, DRW2D), and PCLKB up to 60 MHz for timers and ADCs - ensuring precise timing partitioning across real-time subsystems.
