The Hitachi HD63645F is a microcontroller designed for various embedded applications. It features 512 bytes of RAM, providing essential memory for program execution and data storage. The device includes an interrupt controller with nine external interrupt pins and 34 internal interrupts, along with three selectable priority levels for efficient interrupt handling. Its bus controller allows for address space partitioning and selectable bus specifications, supporting 8-bit or 16-bit access and multiple wait modes.
The refresh controller is directly connectable to 16-bit-wide DRAM and supports CAS-before-RAS refresh and self-refresh modes. A DMA controller is also integrated, offering both short and full address modes with up to four channels for efficient data transfer. The HD63645F comes in a QFP-112 package, suitable for surface-mount applications.
This component is RoHS Compliant, indicating adherence to environmental standards regarding hazardous substances. Its design considerations include flexible interrupt management and robust bus control, making it a versatile choice for embedded systems requiring reliable processing capabilities.

The HD63645F is offered in a QFP-112 package.
It has 512 bytes of RAM.
It provides nine external interrupt pins (NMI, IRQ0-IRQ7), 34 internal interrupts, and three selectable interrupt priority levels.
The bus controller can partition the address space into eight areas with independent bus specifications, supports chip select output per area, selectable 8/16-bit access, two/three-state access, four wait modes, and bus arbitration.
It directly connects to 16-bit-wide DRAM and supports CAS-before-RAS refresh, selectable self-refresh, and pseudo-static RAM refresh.
The DMA controller offers short address mode and full address mode, each with up to four channels, supporting normal or block transfer mode. Activation can occur via ITU interrupts, SCI interrupts, external requests, or auto-request.
Tape & Reel, Cut Tape, Tray, and Tube packaging are available.
