SH-4 core at 200 MHz — ROMless MCU for external memory systems
The Renesas HD6417751RBP200 is a 32-bit single-core MCU built around the SH-4 CPU core, clocked at 200 MHz. It belongs to the SuperH SH7750 series and is supplied in a 256-ball BGA package. The part is ROMless — all program and data memory must be provided externally via the EBI/EMI interface, making it a fit for systems that already carry NOR Flash or SDRAM on a shared bus. Peripheral support includes DMA, POR, WDT, FIFO, SCI, and SmartCard connectivity, with 39 general-purpose I/O lines.
1.35 V supply — design the rail before the BGA
The core runs on a 1.35 V supply. A dedicated regulator or programmable LDO is required on the board. The oscillator is external only.
EOL status — sourcing through independent channels
The HD6417751RBP200 is recorded as end-of-life (EOL). No official successor is listed.
