• SACMOS technology.

GENERAL DESCRIPTION

The PCD5041 DECT Burst Mode Controller (BMC) is a

custom IC that performs the DECT Physical Layer and

MAC Layer time-critical functions, for use in DECT

handset products which comply with the following

standards (and updates):

• DECT CI part 2: Physical layer (DE/RES 3001-2)

• DECT CI part 3 : Medium Access Control layer

(DE/RES 3001-3)

• DECT CI part 7: Security features for DECT

(DE/RES 3001-7)

• DECT CI part 9: Public Access Profile

(DE/RES 3001-9).

The PCD5041 has interfaces to:

• ADPCM CODECs in the handset mode

• A radio transceiver; the interface is fully decoded, and

includes power-down signals

• An external microcontroller.

The PCD5041 is designed to be connected to an ADPCM

CODEC (Philips’ PCD5032, for example) and an

80C51-type microcontroller. Other microcontrollers (e.g.

68000) and CODECs can also be supported.
