Product details
Overview
R5F56217BDFP#H0 from Renesas is a 32-bit RX CPU-based microcontroller delivering 165 DMIPS at 100 MHz, featuring single-precision IEEE-754 FPU, 384 KB on-chip flash, 64 KB SRAM, 32 KB data flash, 10-bit dual-channel DAC, 12-bit × 8-channel or dual 10-bit × 4-channel ADC, Ethernet MAC (10/100 Mbps), USB 2.0 Full-Speed Host/Function/OTG, CAN 2.0B (1 channel, 32 mailboxes), and TFT-LCD support up to WQVGA - deployed in industrial HMI and networked edge controllers.
For engineers reviewing the R5F56217BDFP#H0 datasheet, R5F56217BDFP#H0 pinout, R5F56217BDFP#H0 application, or R5F56217BDFP#H0 equivalent, key selection considerations include LQFP100 package compatibility, 100 MHz real-time deterministic execution, integrated Ethernet+USB+CAN connectivity, low-power Deep Software Standby with RTC retention, and 5 V-tolerant GPIO for legacy interface bridging.
Technical Context
The R5F56217BDFP#H0 implements the RXv1 CPU core with CISC-Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a Memory Protection Unit (MPU) and supports little-endian or big-endian data arrangement, with interrupt response as fast as 5 CPU cycles.
Its clock system combines external 8–14 MHz crystal + PLL for 100 MHz ICLK, internal 125 kHz LOCO for IWDT, and 32 kHz subclock for RTC. The peripheral bus (PCLK) runs up to 50 MHz, while BCLK is unsupported in the 100-pin LQFP variant per datasheet Note 2.
