3.2 Pin Descriptions

The Hirose DF12C board-to-board connector on the module is a 40-pin double-row receptacle.

The table below defines the pin functions. Note that this pin-out is as viewed from the underside of

the Module.

Notes:

* The reset circuitry within the BISM Serial Modules now incorporates a brown-out detector within

the module. Customers migrating from previous modules should check their implementation, as they

may be able to simplify their external power supply design. The reset line has a fixed 10kOhm pull

down resistor to ground.

** Pins 33, 35 and 37 were N/C on BISM1. Pin 39 was a 1V8 monitor. Designers migrating between

designs should be aware that these are now available as I/O. Default configuration is as an input.

*** Pins 2 and 4 were used as GPIO in previous versions of the BISM and WISM. These signals are

used internally for PA control. These pins MUST NOT BE CONNECTED.

PIO lines can be configured through software to be either inputs or outputs with weak or strong pull-

ups or pull-downs. At reset, all PIO lines are configured as inputs with weak pull-downs.

UART_RX, UART_TX, UART_CTS, UART_RTS, UART_RI, UART_DCD and UART_DSR are all 3.3v level

logic. For example, when RX and TX are idle they will be sitting at 3.3V. Conversely for handshaking

pins CTS, RTS, RI, DCD, DSR a 0v is treated as an assertion.
