Ordering Information
GP4020/IG/GQ1N (trays)
GP4020/IG/GQ1Q (tape and reel, 1000 units per reel)
The GP4020 is available in a 100 pin PQFP package in
Industrial (-40°C to +85°C) grade. The ordering code is
standard for screened devices
Description
The GP4020 is a complete digital baseband processor
for a Global Positioning System (GPS) receiver. It
combines the 12-channel correlator function of the
GP2021 with an advanced ARM7TDMI (Thumb)
microprocessor to achieve a higher level of integration,
reduced system cost, reduced power consumption and
added functionality. The GP4020 complements the
GP2015 and GP2010 C/A code RF downconverters
available from Zarlink Semiconductor.
The correlator section contains 12 identical tracking
module blocks, one for each channel. Each channel
contains all the components necessary for acquiring
and tracking the received signal, and also contains
other functional blocks, which are used to produce part
of the measurement data set. Individual channels may
be deactivated for systems not requiring full 12-channel
operation and thus allowing for reduced power
consumption and processor loading.
The microprocessor section contains the Firefly MF1
microcontroller core, which includes an ARM7TDMI
with a Thumb instruction de-compressor plus the Firefly
BµILD module. Also included are a second UART,
BµILD Serial I/O, General I/O and Watchdog functions.
