See Electrically Erasable Programmable Read-Only Memory.
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.
A programmable, digitally-tuned, temperature-compensated
16.8 MHz crystal oscillator.
Federal Communications Commission.
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.
A custom integrated circuit providing interface support for the Patriot
and GCAP II ICs.
See Florida Manual Revision.
A document that provides interim updates to a publication until the
entire publication can be updated and reissued.
A Motorola-proprietary, CMOS fractional-N frequency synthesizer with
built-in, dual-port modulation.
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.
See Global Control Audio and Power IC.
Pins whose function is programmable.
