BCM43236/BCM43236B Preliminary Data Sheet

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

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.

Note: These five pins are muxed with the JTAG interface.
