MOTOROLA MVME165
Specifications
CACHE
The MC68040 contains an internal 8Kb cache (with 4K instruction and 4K data) which supports one cycle read accesses and external (to the processor) bus snooping of local DRAM memory.
Clock Signal
25.0-33.0 MHz CPU clock frequency (The specific operating frequency is determined by the oscillator installed.)
DRAM
4/16Mb of DRAM (Dynamic RAM) are provided using either one megabit or four megabit RAMs.
FPU
The MC68040 contains a Floating Point Unit (FPU) which implements a subset of the MC68881/MC68882 FPU.
I/O
Two RS-232C asynchronous serial ports are provided through the MC68681 DUART (Dual Asynchronous Receiver/Transmitter).
Microprocessor
MC68040 32-bit microprocessor
MMU
The MC68040 contains an internal Memory Management Unit (Na" which supports 4K or 8K page sizes.
Power requirements
+5Vdc, 5.9 Amps maximum (5.4 A typical), +12Vdc, 250 mA maximum, -12Vdc, 250 mA maximum
ROM
Two 32-pin JEDEC sockets which provide support for 128K x 8, or 256K x 8 EPROMs (165Bug supplied with 256K x 8 devices).
SRAM
One 28-pin JEDEC socket which provides 8K x 8 of NVRAM (Non-Volatile RAM) and a TOD (Time-Of-Day) Clock.
Storage temperature
-40' to 85' C
Timers
Three 24-bit counter/timers are in the LRC and one 16-bit timer is in the MC68681 DUART.
VMEbus
A VMEbus master/slave interface (A321A24/D321D16) is implemented with the MVME6000 (VMEchip).
VSB
A VSB (bus) master/slave interface (A32/D32) is implemented using the MVSB2400 (VSBchip).

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
