HD6417709F80B

HD6417709F80B is a legacy Hitachi/Renesas 16‑bit microcontroller from the HD641/HD64 family. It combines a 16‑bit CPU core with on‑chip ROM and RAM and provides common embedded peripherals such as I/O ports, timers, and serial interfaces, with support for an external bus in some configurations. The F80B suffix typically denotes a particular package and memory variant (often an 80‑pin package). It targets embedded control tasks in consumer electronics, appliances, and industrial equipment. As an older part, current tooling and documentation may be limited; consult the Renesas/Hitachi product archive or the official datasheet for exact specifications (CPU speed, memory map, peripherals, interrupt architecture) and available development tools.

- Pin count: 80 pins (LQFP80 package).
- Function: An HD6417709F80B is a microcontroller unit (MCU) from the Hitachi/Renesas HD6417x/HD64170x family—16‑bit MCU core with on‑chip ROM/RAM and integrated peripherals (GPIO, timers, serial interfaces, etc.) for embedded control.

Manufacturer: Hitachi, Ltd. (Hitachi Semiconductor).
Company type: A Japanese multinational conglomerate known for electronics, IT, and industrial systems; its semiconductor business was later reorganized into Renesas Electronics.
