Densan DVE441 (9215A)
Product Name
Densan DVE441 9215A. Retrieved public technical sources did not return a Densan datasheet, schematic or official product page for this exact model and suffix. Verified board-level values cannot be stated without manufacturer documentation.
Product Introduction
DVE441 9215A appears in the Densan DVE product family naming convention, but no reliable public specification was found during retrieval. Treat all electrical, mechanical and firmware values as unconfirmed until the official Densan datasheet or board label is supplied.
Densan DVE-SH7700
Product Name
Densan DVE-SH7700. Retrieved sources did not provide a Densan board manual for this model. The data below is the SuperH SH7700/SH3 microcontroller family reference for component-level identification only.
Product Introduction
SH7700 is a 32-bit RISC microcomputer family in the SuperH SH3 series. It is intended for embedded applications requiring higher integration than earlier SH2 devices, combining RISC CPU core, memory controller and configurable peripherals. Densan DVE-SH7700, if built around this silicon, would function as an embedded single-board or VME processor module.
Densan DVE-SH7604 (9271)
Product Introduction
SH7604 is a 32-bit RISC single-chip microcontroller built on the SuperH architecture. It integrates CPU core, cache, multiplier, divide unit, direct memory access controller, timers, serial interface, interrupt controller and bus state controller. On a Densan carrier board it would serve as the main embedded processor for real-time control, communication management and VME/industrial I/O orchestration.
Densan DVE-511-PBF (9559A)
Product Name
Densan DVE-511-PBF(9559A) VME control and signal PCB, 8-channel slave configuration.
Product Overview
Densan DVE-511-PBF(9559A) is an industrial control printed circuit board used for machine power distribution and signal transmission. Surplus and equipment listings identify DVE-511 as an 8-channel VME slave PCB with DPM-506A association, removed from Rudolph F30 300 mm wafer mounter and defect-inspection systems. The PBF suffix denotes a lead-free process build.
Densan DVE-503 (9204A)
Product Name
Densan DVE-503(9204A) VME industrial module.
Product Overview
Densan DVE-503(9204A) is listed by the user as a Densan VME-class module. Public retrieval did not return a Densan-specific factory datasheet for DVE-503 with 9204A. Third-party DVME-503 memory modules exist from other manufacturers, but those specifications do not apply to Densan DVE-503 unless the original equipment documentation explicitly confirms equivalence.
Densan DVE-486-22S (9387A)
Product Name
Densan DVE-486-22S(9387A) VME 486-class single-board computer, S variant.
Product Overview
Densan DVE-486-22S(9387A) is listed as a VME SBC, single-board computer PCB, model DVE 486/22S, made in Japan and supplied as working surplus. The S suffix commonly denotes a variant of the DVE-486/22 base model, but the retrieved surplus listings do not publish the exact electrical differences between 22 and 22S.
Densan DVE-486-22 (9387A)
Product Name
Densan DVE-486-22(9387A) VME 486-class single-board computer.
Product Overview
Densan DVE-486-22(9387A) is confirmed in industrial surplus channels as a VME SBC, single-board computer PCB, made in Japan and supplied as working surplus. The model line DVE 486/22S is associated with the same 9387A listing family. CPU clock, memory size and onboard I/O for the 22 non-S variant are not included in retrieved public documentation.
Densan DVE-486-20A (9295A)
Product Name
Densan DVE-486-20A(9295A) VME 486-class single-board computer.
Product Overview
Densan DVE-486-20A belongs to the Densan DVE-486 VME SBC family. The 9295A marker identifies the board revision. Public surplus listings for the 20A revision were not retrieved with CPU, memory and I/O details; the information below combines confirmed Densan 486-family VME context with Intel 80486 architecture data applicable to 486-class SBCs.
Densan DVE-440(9214)
Product Name
Densan DVE-440(9214) VME industrial board.
Product Overview
Densan DVE-440(9214) is listed in industrial surplus channels as a Densan VME board for factory automation, SMT, industrial PC, controller and MRO applications. The 9214 marker is treated as the board revision or internal production code. Complete factory electrical documentation was not retrieved.
Densan DVE-102A
Product Name
Densan DVE-102A industrial graphic board or generic circuit board, depending on supplied revision.
Product Overview
Densan DVE-102A appears in two verified surplus configurations. One listing describes a Densan graphic board with 128 KB SRAM. A separate industrial listing describes DVE-102A with alternative number 9327A as a used circuit board. Confirm the exact sticker, firmware label and connector layout before defining the board as a graphics module or a general-purpose control card.
Densan DVESH7750
Product Overview
Densan supplies VME and embedded CPU boards for industrial systems, and Densan is listed among solution partners for SH7750 reference and development platforms. The model suffix SH7750 aligns with the Renesas/Hitachi SH-4 SuperH microprocessor family. Where DVESH7750 integrates an SH7750 core, the processor parameters below apply; board-level I/O assignments must be confirmed from the original Densan schematic.
