RFID reader writer IC (CR95HF)
1 Description
The CR95HF is an integrated transceiver IC for contactless applications.
The CR95HF manages the frame coding and decoding in Reader mode for standard
applications such as NFC, proximity and vicinity standards.
The CR95HF embeds the Analog Front End for 13.56 MHz Air Interface.
The CR95HF supports ISO/IEC 14443 B protocols.

3 Power management and operating modes
3.1 Operating modes
The CR95HF has 2 operating modes: Idle and Active. In Active mode, the CR95HF communicates
actively with a tag or an external MCU. Idle mode includes two low consumption states: Hibernate and
Tag Detector.The CR95HF can switch from one mode to another.
Table 2. Operating modes
Hibernate and Tag-Detector states can only be activated by a command from the external
MCU. As soon as Application environmentany of these states are activated, the CR95HF
can no longer communicate with the external MCU. It can only be woken up.
The behavior of the CR95HF in 'Tag-Detector' state is defined by the Idle command.

Federal Communications Commission (FCC) Statement:
15.105(b)
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures: -Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a
circuit different from that to which the receiver is connected. -Consult the dealer or an experienced
radio/TV technician for help.
15.21:
You are cautioned that changes or modifications not expressly approved by the part responsible for
compliance could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
1.This Transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
2.This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20 centimeters
between the radiator and your body.
FCC RF Exposure requirements:
This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna
or transmitter.
15.19:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1) this device may not cause harmful interference and
2) this device must accept any interference received, including interference that may cause undesired
operation of the device.

Industry Canada Statement:
This device complies with ISED’s applicable licence-exempt RSSs. Operation is subject to the following
two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired operation of
the device.
RF Radiation Exposure Statement:
This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20 centimeters between the
