Overview
R5F56609EGFB#10 from Renesas is a 32-bit RXv3 microcontroller designed for industrial and automotive control applications requiring high reliability, real-time performance, and functional safety support. It operates at up to 120 MHz, integrates 1 Mbyte of on-chip code flash memory with zero-wait-state access, 128 Kbytes of SRAM, 32 Kbytes of data flash (100,000 write/erase cycles), and features CAN FD, 12-bit A/D and D/A converters, RTC, and IEC60730-compliant self-test functions.
For engineers reviewing the R5F56609EGFB#10 datasheet, R5F56609EGFB#10 pinout, R5F56609EGFB#10 application, or R5F56609EGFB#10 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, G-grade temperature range (–40°C to +105°C), dual D/A outputs usable as comparator references, and integrated ELC for interrupt-free peripheral coordination in low-power modes.
Technical Context
The R5F56609EGFB#10 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, delivering 709 CoreMark at 120 MHz. It supports little-endian or big-endian data arrangement and includes 16 register banks for fast context switching - critical for deterministic real-time task handling in motor control and safety-critical systems.
Its clock system combines an 8–24 MHz main oscillator, 32.768 kHz sub-clock, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocking: ICLK up to 120 MHz, PCLKA up to 120 MHz (for MTU3a/RSPI), PCLKB up to 60 MHz (for TMR/CMT), and ADCLK up to 60 MHz - allowing precise timing partitioning across analog, control, and communication subsystems.
