BCM43236/BCM43236B Preliminary Data Sheet
Global Functions
Bluetooth Coexistence Interface
A 5-wire handshake interface is provided to enable signalling between the device and an external Bluetooth
device host to manage sharing of the wireless medium for optimum performance. The signals provided are:
• btcx_tx_conf
• btcx_rf_active
• btcx_status
• btcx_prisel
• btcx_freq
Note: These five pins are muxed with the JTAG interface.
OTP
The BCM43236/BCM43236B chips contain an on-chip One-Time-Programmable (OTP) area that can be used for
nonvolatile storage of WLAN information such as a MAC address and other hardware-specific parameters. The
total area available for programming is 2 Kbits.
JTAG Interface
The BCM43236/BCM43236B chips support the IEEE 1149.1 JTAG boundary-scan standard for testing the device
packaging and PCB manufacturing.
UART Interface
One UART interface is provided that can be attached to RS-232 Data Termination Equipment (DTE) for
exchanging and managing data with other serial devices. The UART interface is primarily used for debugging
and development.
Serial Flash Interface
Serial flash is available regardless of whether USB 2.0 operation is enabled or disabled. The flash interface is an
STMicroelectronics^®-compatible 4-pin interface.
