Unpacking and Special Handling Instructions
This PEP product is carefully designed for a long and fault-free life; nonetheless, its life expectancy can be drastically
reduced by improper treatment during unpacking and installation.
Observe standard anti-static precautions when changing piggybacks, ROM devices, jumper settings etc. If the product
contains batteries for RTC or memory back-up, ensure that the board is not placed on conductive surfaces, including
anti-static plastics or sponges. These can cause shorts and damage to the batteries or tracks on the board.
When installing piggybacks, switch off the power mains.
Furthermore, do not exceed the specified operational temperature ranges of the board version ordered. If batteries are
present, their temperature restrictions must be taken into account.
Keep all the original packaging material for future storage or warranty shipments. If it is necessary to store or ship the
board, re-pack it as it was originally packed.

PEP Modular Computers TwoYear Limited Warranty
We grant the original purchaser of PEP products the following hardware warranty. No other warranties that may be
granted or implied by anyone on behalf of PEP are valid unless the consumer has the expressed written consent of PEP
Modular Computers.
PEP Modular Computers warrants their own products (excluding software) to be free from defects in workmanship
and materials for a period of 24 consecutive months from the date of purchase. This warranty is not transferable nor
extendible to cover any other consumers or long term storage of the product.
This warranty does not cover products which have been modified, altered, or repaired by any other party than PEP
Modular Computers or their authorized agents. Furthermore, any product which has been, or is suspected of being
damaged as a result of negligence, misuse, incorrect handling, servicing or maintenance; or has been damaged as a re-
sult of excessive current/voltage or temperature; or has had its serial number(s), any other markings, or parts thereof

A customer who has not excluded his eligibility for this warranty may, in the event of any claim, return the product at
the earliest possible convenience, together with a copy of the original proof of purchase, a full description of the ap-
plication it is used on, and a description of the defect; to the original place of purchase. Pack the product in such a way
as to ensure safe transportation (we recommend the original packing materials), whereby PEP undertakes to repair or

1.1 Product Overview
The VMEM-F1 is a FLASH memory module with a maximum capacity of up to 192 Mbyte. The mod-
ule is split into a base board containing 64 Mbytes and an optional FLASH Extension Board containing
up to 128 Mbyte. Both, base board and Extension Board cover a single 3U VMEbus slot.
TheVMEM-F1 has 48 memory banks , each with a size of 4 Mbyte. The FLASH is built up withAMDs
29F016 chips forming a 16 bit wide data path.
The VMEM-F1 occupies a programmable address range of 4Mbyte within the VMEbus A24/D16 and
User Defined address spaces.
FLASH memory enabled status and FLASH Busy/Ready status are displayed by two LEDs on the front
panel. Additionally, a general Write Protection can be selected via a front panel switch.
A small EEPROM on the base board as well as on the extension board can be used for storing board spe-
cific (board Id) and application specific parameters.

2.2 Addressing Board Configuration Registers
The VMEM-F1 occupies 4 kByte in the VMEbus A16 address space (Short I/O) where the board con-
figuration registers are situated. The base address of this 4 kByte block is selected using a jumper (see
Chapter 3 Configuration for more details). It can be accessed inA16 supervisory orA16 non-privaleged
address space.
Memory base address, size, AM code and some board control/status functions can be programmed via
the board configuration registers. The memory base address register must be initialized before FLASH
memory access is enabled.

2.3 Addressing Memory
The VMEM-F1 occupies 4 MByte of the VMEbus A24/D16 address space. The base address is pro-
grammable in 4 MByte blocks via the board base address register (see ...)
In order to reach the whole of the 192 MByte, the area is paged in blocks of 4 MByte.
On the VMEM-F1, one page represents one FLASH bank, which is physically built up of a pair of
FLASH chips. Within one page, the whole memory can be linearly addressed. The FLASH page is se-
lected via the FLASH page register (see...).
Before addressing memory, the following configuration registers must be initialized:
• Memory base address register , which defines the FLASH memory address.
• Memory address mask register , which defines the FLASH page size.
• Memory address modifier code register , which defines the board address modifier codes.
• Memory page register , which defines the currently used FLASH page.
