A20737C - 20737 System on Chip Series

The A20737C is a high-performance, FCC & IC certified and ETSI-compliant SOC module featuring Bluetooth® SMART technology that incorporates the Broadcom BCM20737 transceiver chip in one of the industry’s smallest package (11 x 13 x 2.5 mm).

The module incorporates an EEPROM, 24MHz crystal and the required RF matching and filtering for regulatory compliance. The modules operate in the global unlicensed 2.4GHz ISM/SRD frequency band. These radio modules are ideal for achieving low power wireless connectivity without having to deal with extensive protocol, RF design and regulatory compliance, allowing quick time to market. The modules are 100% RF-tested to provide consistent performance.

The A20737C has a RoHS-compliant ENIG finish and is packaged in 36-piece matrix trays or on 500-piece tape & reel for high-volume automated manufacturing.
