Based on the company's Bluetooth 1.1-compliant core combined with an ARM7 TDMI processor and AMBA bus, the PBM 990 90 baseband controller IC supports up to seven slaves, making it suitable for both point-to-point and point-to-multipoint applications.

The device offers HCI connectivity that is provided through UARTs or a USB port. One UART supports HCI connectivity up to 921Kbps, while a second can be used at up to 230Kbps for production and debugging purposes. The USB port is a self-powered, USB 2.0 compliant, full-speed device interface.

Optional connectivity can be provided by up to 10 GPIO ports. A I?C interface can be used to communicate with PCM codecs or EEPROMs.

The PBM 990 90 also features 64KB of on-chip RAM that enables target applications to be embedded within the controller. The controller can also adapt to several input clock frequencies, while its internal system clock can be configured to the optimal frequency, allowing the target application to achieve a balance of power consumption and performance.

The PBM 990 90 supports 128-bit encryption and provides park, sniff, and hold connectivity modes.
