CYW20736
The following additional profiles can be supported1 from RAM:
■ Blood glucose monitor
■ Temperature alarm
■ Location
■ Custom profile
1.1.6 Test Mode Support
The CYW20736 fully supports Bluetooth Test mode, as described in the Bluetooth low energy specification.
1.2 Infrared Modulator
The CYW20736 includes hardware support for infrared TX. The hardware can transmit both modulated and unmodulated wave-
forms. For modulated waveforms, hardware inserts the desired carrier frequency into all IR transmissions. IR TX can be sourced
from firmware-supplied descriptors, a programmable bit, or the peripheral UART transmitter.
If descriptors are used, they include IR on/off state and the duration between 1–32767 µsec. The CYW20736 IR TX firmware driver
inserts this information in a hardware FIFO and makes sure that all descriptors are played out without a glitch due to underrun (see
Figure 2).

1.3 Infrared Learning
The CYW20736 includes hardware support for infrared learning. The hardware can detect both modulated and unmodulated sig-
nals. For modulated signals, the CYW20736 can detect carrier frequencies between 10 kHz–500 kHz and the duration that the sig-
nal is present or absent. The CYW20736 firmware driver supports further analysis and compression of learned signal. The learned
signal can then be played back through the CYW20736 IR TX subsystem (see Figure 3).
