Product overview
Block diagram
The A2541E24C is a high-performance, FCC & IC certified and
ETSI-compliant SOC module featuring Bluetooth® SMART
technology that incorporates the Texas Instruments CC2541
transceiver chip and CC2590 range extender in one of the
industry’s smallest package (11 x 19 x 2.5 mm). The module
incorporates two crystals 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 A2541E24C has an RoHS-compliant ENIG finish and is
packaged in 27-piece matrix trays or on 500-piece tape & reel
for high-volume automated manufacturing.
