The CP2022 drive is designed to operate either as a master drive (C
Drive) or a slave (D Drive) depending on the state of Jumper E1.
When E1 is closed, the drive will assume the role of master, when
open it will act as the slave. In single drive configurations E1
must be closed.

The drive may be mounted in any attitude!
Recommended Mounting Configuration
----------------------------------
The CP2022 is designed to be used in applications where the unit
may experience shock and vibrations at greater levels than larger
and heavier disk drives.
The design features which allow greater shock tolerance are the use
of rugged heads and media, a dedicated landing zone, closed loop
servo positioning and specially designed motor and actuator
assemblies.
Four (4) mounting points are provided to the customer. The drive is
mounted from the bottom using 4-40 screws 1/4" max. insertion.
The system integrator should allow ventilation to the drive to ensure
reliable drive operation over the operating temperature range.
For additional vibration isolation, an external suspension system
may be used.
Interface Connector
-------------------
The CP2022 has a 44 pin right angle interface/power connector
mounted on the PCB. The recommended mating connector is Dupont part
number: 86455-144. The drive is intended to be directly connected
through a connector. It is not recommended to solder the connector to
a motherboard or other PCBA. Note that through board configuration
must allow for 50 pins.
Diagnostic Routines
-------------------
The microprocessor performs diagnostics upon application of power.
If an error is detected, the CP2022 will not come ready.
Magnetic Field
--------------
The externally induced magnetic flux density does not exceed 6 gauss
as measured at the disk surface.
Acoustic Noise
--------------
40 dBA max. at 1 meter

Key Features
------------
The CP2022 is a high performance 2.5 inch low-profile (0.69")
21.4 megabyte (formatted) disk drive with average seek time not do
exceed 23ms which is designed to operate on IBM PC/XT & PC/AT or
equivalent computers. The drives feature a low 5V power requirement
and high shock resistance, enabling battery operation in portable
environments.
- 2.5" Form factor
- Single 5 Volt supply
- Low power requirements
- 5.5 oz
- High performance rotary voice coil actuator with embedded servo
system.
- Single connector for power & interface
- Run length limited code (2/7)
- High shock resistance
- Internal air filtration system
- Sealed HDA
- Automatic actuator latch over data free landing zone during standby
mode or power-down
- Microprocessor-controlled diagnostics routines that are auto-
matically executed at start-up.
- Automatic error correction and retries
- Block size 512 bytes
- PC XT/AT Interface (interface selectable)
- 1:1 sector interleave
- Look Ahead Read Capability
- 8K Buffer
AT Mode
-------
The Host addresses the drive using programmed I/O. This method
requires that the desired register address be placed on the three
address lines A2-A0, a proper drive chip select is asserted and read
or write strobe (-IOR/-IOW) is given to the chip.
The Host generates two independent chip selects on the interface. The
high order chip select, -CS1, is used to access register 3F6 or 3F7.
The low order chip select, -CS0, is used to address registers 1F0 -
1F7.
The Host data bus 15-8 is only enabled when I016 enable is active and
the Host is addressing the data register for transferring data and
not the ECC bytes which are only transferred if the operation is read
or write long.
XT Mode
-------
The Host addresses the drive using programmed I/O. This method re-
quires that the desired register address be placed on the address
lines A1 - A0, a proper drive select is asserted and a read or write
strobe (-IOR/-IOW) is given to the drive. The drive is normally
decoded at base address 320H.

Functional Description
----------------------
The CP2022 contains all necessary mechanical and electronic parts to
interpret control signals, position the recording heads over the
desired track, read and write data, and provide a contaminant free
environment for the heads and disks.
Read/Write and Control Electronics
----------------------------------
One integrated circuit is mounted within the sealed enclosure in
close proximity to the read/write heads. Its function is to provide
one of two head selection, read preamplification, and write drive
circuitry.
The single microprocessor controlled circuit card provides the
remaining electronic functions which include:
- Read/Write Circuitry
- Rotary Actuator Control
- Interface Control
- Spin Speed Control
- Dynamic Braking
- Power Management
At power down or the start of STANDBY MODE the heads are auto-
matically retracted to the inner diameter of the disk and are latched
and parked on a landing zone that is inside the data tracks.
Drive Mechanism
---------------
A brushless DC direct drive motor rotates the spindle at 3433 RPM.
The motor/spindle assembly is balanced to provide minimal mechanical
runout to the disks and to reduce vibration of the HDA. A dynamic
brake is used to provide a fast stop to the spindle motor when power
is removed, or upon initiation of STANDBY MODE.
Air Filtration System
---------------------
Within the sealed enclosure, a 0.3 micron filter which provides a
clean environment for the heads and disks.
Head Positioning Mechanism
--------------------------
The two read/write heads are supported by a mechanism coupled to the
voice coil actuator.
Read/Write Heads and Disks
--------------------------
Data is recorded on 65mm diameter disk through two miniature thin
film heads.
Error Correction
----------------
The CP2022 performs internal error correction. The error correction
polynominal is capable of correcting one error burst with a maximum
of 8 bits per 512 byte block.
Reliability and Maintenance

MTBF 40,000 hours POH (population is min. of 100
units)
