Densan DVE-SH7604
Product Introduction
The Densan DVE-SH7604 is a member of the Densan DVE product family of embedded controller boards. It carries the SH7604 32-bit RISC microprocessor as its central processing unit. Retrieved public sources do not provide a distinct Densan board manual for the DVE-SH7604 model without the 9271 suffix; the technical parameters of the SH7604 silicon described in the 9271 entry apply at the component level. The board functions as an embedded single-board or VME processor module for industrial control applications.
Detailed content
Technical Specifications
Component-level technical specifications are defined by the SH7604 microprocessor. Refer to the DVE-SH7604 (9271) entry for detailed electrical and timing parameters. Board-specific specifications such as supply voltage, current consumption, mechanical dimensions, and connector assignments are not published in retrieved public documentation.
Functional Features
The board provides the processing, memory interfacing, serial communication, and interrupt handling capabilities of the SH7604 microcontroller. A serial communication interface (SCI) supports asynchronous and clocked synchronous operation. A multiprocessor communication function enables serial communication among multiple processors. The DMAC and bus state controller provide high-performance data movement and memory management.
Application Scenarios
Embedded real-time control, industrial automation, VME system orchestration, and communication management tasks requiring a compact 32-bit RISC processing platform.
Material Composition
Constructed as a printed circuit board assembly with the SH7604 microcontroller and associated passive and active components. PCB substrate material and solder composition details are not published.
Structural Characteristics
VME-class form factor. The board integrates the SH7604 microcontroller with supporting memory, interface, and power management circuitry.
Working Principle
Identical to the DVE-SH7604 (9271) working principle, centered on the SH7604 RISC processor executing instructions and managing peripheral and memory interfaces through its integrated bus state controller, DMAC, SCI, and interrupt controller.
Installation Requirements
Installation in a VMEbus chassis or as a standalone embedded controller depending on the Densan carrier configuration. Power-on sequencing requirements for synchronous DRAM initialization apply.
Usage Precautions
The SH7604 does not support little-endian mode for 8-bit data bus devices. Endian conversion is limited to the CS2 space. Proper refresh control configuration is required for DRAM and pseudo-SRAM operation.
