Overview
The Broadcom BCM58102 secure processor, which supports Windows 7/8/10,
follows the ISO14443 Type A and Type B Reader specification. It can be used in PC or
other embedded devices, and allows linking ISO 14443 Type A and Type B cards
through the air. It supports for the ISO/IEC 18092, ISO/IEC 21481, ISO/IEC 14443
Types A, B, and B’, Japanese Industrial Standard (JIS) (X) 6319-4, and ISO/IEC 15693
standards. Both Reader and Card communicate via near-field inductive coupling and
load modulation techniques.
The ISO14443 Type A and Type B Reader operate in the globally available 13.56 MHz
unlicensed Industrial, Scientific and Medical (ISM) band and uses ASK/BPSK/ALM
(Active Load Modulation) with sub-carrier communication techniques.
Functional Description
The BCM58102 system-on-chip (SoC) includes Peripheral I/Os, Baseband, Logic
Control, 32-Bit Cortex-M3 CPU, Transmitter & Receiver.
The BCM58202 system-on-chip (SoC) includes Peripheral I/Os, Baseband, Logic Control,
32-Bit Cortex-M3 CPU, Transmitter & Receiver.
1. Tx Mode
Digital signals are converted by Baseband circuits, then modulated and converted to 13.56
MHz RF signals by the RF Transceiver. Finally, the RF signals are transmitted into the air
through reader coil via inductive coupling method.
2. Rx Mode
Card modulates signal on to 13.56 MHz carrier frequency via load modulation, this signal is
filtered and enters to BCM58202 chip. The received RF signals are demodulated by the
Transceiver to analog I, Q signals. The Baseband circuit converts the I, Q signals into digital
signals and sends the I, Q signals to DSP and logic for decoding. The analog-front-end (AFE)
