GENERAL DESCRIPTION
The Broadcom® BCM20793S is an NFC-compliant, highly integrated, low power, low cost, 40 nm NFC controller combined with an integrated EEPROM for battery-off operation in a single package. The BCM20793S is an update to the BCM20793, which features secure configuration and patch download for applications involving the management and operation of NFC secure elements. The BCM20793S sizeoptimized architecture is housed in a QFN-34L package that measures 4.0 mm × 4.5 mm × 0.9 mm (nominal), and requires minimal external components. This brings the traditional two-chip NFC controller and EEPROM for battery-off operation into a single package solution to minimize PCB footprint. Refer to the architecture block diagram in Figure 1 on page 2.
