A special type of PROM that can be erased by exposing it to an
electrical charge. An EEPROM retains its contents even when the
power is turned off.
Electromagnetic Emissions.
Electrostatic Discharge.
Federal Communications Commission.
Field-Effect Transistor.
Code executed by an embedded processor such as the Host or DSP in
a subscriber radio. This type of code is typically resident in non-volatile
memory and as such is more difficult to change than code executed
from RAM.
See frequency generation unit.
A non-volatile memory device similar to an EEPROM. Flash memory
can be erased and reprogrammed in blocks instead of one byte at a
time.
A 13-digit code which uniquely identifies the System Software Package
and Software Revenue Options that are enabled in a particular
subscriber radio. FLASHcodes are only applicable for radios which are
upgradeable through the FLASHport process.
A Motorola term that describes the ability of a radio to change memory.
Every FLASHport radio contains a FLASHport EEPROM memory chip
that can be software written and rewritten to, again and again.
See Florida Manual Revision.
A publication that provides supplemental information for its parent
publication before it is revised and reissued.
Number of times a complete electromagnetic-wave cycle occurs in a
fixed unit of time (usually one second).
This unit generates ultra-stable, low-phase noise master clock and other
derived synchronization clocks that are distributed throughout the
communication network.
Pins whose function is programmable.
See General-Purpose Input/Output.
Object code executed by the host processor in an ASTRO subscriber
radio. The host is responsible for control-oriented tasks such as
decoding and responding to user inputs.
See integrated circuit.
