Product Description
The RT5370 is a highly integrated MAC/BBP and 2.4
GHz RF/PA/LNA single chip with 150Mbps PHY rate
supporting. It fully complies with IEEE 802.11n and IEEE
802.11 b/g feature rich wireless connectivity at high
standards, delivers reliable, cost-effective, throughput
from an extended distance. Optimized RF architecture
and baseband algorithms provide superb performance
and low power consumption. Intelligent MAC design
deploys a high efficient DMA engine and hardware data
processing accelerators without overloading the host
processor. The RT5370 is designed to support standard
based features in the areas of security, quality of
service and international regulation, giving end users
the greatest performance anytime in any circumstance.

2.4 Storage Condition
The calculated shelf life in sealed bag is 12 months if stored between 0°C and 40°C at less than 90% relative
humidity (RH). After the bag is opened, devices that are subjected to solder reflow or other high temperature
processes must be handled in the following manner:
a) Mounted within 168-hours of factory conditions < 30 °C /60%RH
b) Storage humidity needs to maintained at <10% RH
c) Baking is necessary if customer expose the component to air over 168 hrs, baking condition: 125°C / 8hrs
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
