Our sales will reply to
your request by email within 24 hours.
1. You'll receive an order information email in your inbox.
(Please remember to check the spam folder if you didn't hear from us).
2. Since inventories and prices may fluctuate to some
extent, the sales manager is going to reconfirm the order and let you know if there
are any updates.
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The basic freight (for package ≤0.5kg or corresponding volume) depends on the time
zone and country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:
FedEx International, 5-7 business days.

The OM9663 is a highly integrated transceiver IC for contactless communication at
13.56 MHz.
The OM9663 transceiver IC supports the following operating modes
• Read/write mode supporting ISO/IEC 14443A/MIFARE
• Read/write mode supporting ISO/IEC 14443B
• Read/write mode supporting JIS X 6319-4 (comparable with FeliCa1 (see
Section 21.5) scheme)
• Passive initiator mode according to ISO/IEC 18092
• Read/write mode supporting ISO/IEC 15693
• Read/write mode supporting ICODE EPC UID/ EPC OTP
• Read/write mode supporting ISO/IEC 18000-3 mode 3/ EPC Class-1 HF
The OM9663’s internal transmitter is able to drive a reader/writer antenna designed to
communicate with ISO/IEC 14443A/MIFARE cards and transponders without additional
active circuitry. The digital module manages the complete ISO/IEC 14443A framing and
error detection functionality (parity and CRC).
The OM9663 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,
MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The OM9663
supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions.
The OM9663 supports layer 2 and 3 of the ISO/IEC 14443B reader/writer communication
scheme except anticollision. The anticollision needs to be implemented in the firmware of
the host controller as well as in the upper layers.
The OM9663 is able to demodulate and decode FeliCa coded signals.The FeliCa receiver
part provides the demodulation and decoding circuitry for FeliCa coded signals. The
OM9663 handles the FeliCa framing and error detection such as CRC. The OM9663
supports FeliCa higher transfer speeds of up to 424 kbit/s in both directions.
The OM9663 is supporting the P2P passive initiator mode in accordance with
ISO/IEC 18092.
The OM9663 supports the vicinity protocol according to ISO/IEC15693, EPC UID and
ISO/IEC 18000-3 mode 3/ EPC Class-1 HF.
The following host interfaces are supported:
• Serial Peripheral Interface (SPI)
• Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)
• I
2C-bus interface (two versions are implemented: I2C and I2CL)
The OM9663 supports the connection of a secure access module (SAM). A dedicated
separate I2C interface is implemented for a connection of the SAM. The SAM can be used
for high secure key storage and acts as a very performant crypto coprocessor. A
dedicated SAM is available for connection to the OM9663.
