HD6417709F80B

HD6417709F80B is a legacy microcontroller from Hitachi/Renesas in the HD64 family, used for embedded control tasks. It’s a 16‑bit MCU designed for real‑time embedded applications and integrates basic on‑chip resources and peripherals.
Key points:
- Core and memory: 16‑bit CPU with on‑chip flash/RAM (density varies by variant).
- Peripherals: common MCU peripherals such as timers, serial interfaces (SCI), GPIO, and interrupt support (exact mix depends on the revision).
- Package/variant: the F80B suffix denotes a specific package/density option within the HD64 family.
- Tooling: development relies on legacy Renesas/Hitachi toolchains and documentation; public datasheets are limited.
- Use case: suited for automotive, industrial, or other embedded controllers in older designs.
If you need exact specifications, pinout, or toolchain requirements, consult the original HD6417709F80B datasheet or Renesas/Hitachi archival manuals. Availability is often limited, so you may need to reach out to Renesas support or legacy distributors for documentation or cross references.
