26 PART 5 – Appendix
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes:
1. l'appareil ne doit pas produire de brouillage, et
2. l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage
est susceptible d'en compromettre le fonctionnement.
2.3
Electrostatic discharge considerations
Although damage from electrostatic discharge (ESD) is much less common on these devices than on early
CMOS circuits, normal handling precautions should be used to avoid exposure to static discharge.
Qualification tests are performed to ensure that these devices can withstand exposure to reasonable levels
of static without suffering any permanent damage.
All ESD testing is in conformity with the JESD22 Stress Test Qualification for Commercial Grade
Integrated Circuits. During the device qualification ESD stresses were performed for the human body
model (HBM), the machine model (MM) and the charge device model (CDM).
All latch-up test testing is in conformity with the JESD78 IC Latch-Up Test.
When operating or handling the development boards or components, Freescale strongly recommends
using at least the grounding wrist straps plus any or all of the following ESD dissipation methods:
•
Flexible fabric, solid fixed size, or disposable ESD wrist straps
•
Static control workstations, static control monitors and table or floor static control systems
•
Static control packaging and transportation materials and environmental systems

MCR20A transceiver overview and description
3.1
Introduction
The FRDM-CR20A development board is an evaluation environment to support the Freescale
MCR20AVHM SoC transceiver (MCR20A), a 2.4 GHz Industrial, Scientific, and Medical (ISM)
transceiver intended for the IEEE 802.15.4 Standard.
The MCR20A is a highly-integrated, cost-effective radio transceiver operating in the 2.36 GHz to 2.48
GHz range, usually combined with a software stack and a Freescale Kinetis MCU to implement an IEEE
802.15.4 Standard platform solution.
Freescale supplements the MCR20A transceiver with tools and software that include hardware evaluation
and development boards, software development IDE and applications, drivers, custom PHY usable with
the Freescale IEEE 802.15.4 compatible MAC.
