The headset reference design is based on the MT0750 OneChip. The MT0750-HS integrates the Bluetooth headset solution including the radio, baseband, processor, audio CODEC, and flash program memory into a single BGA package. The chip’s built-in CODEC directly connects to the headset speaker and microphone. The onboard processor and execution of man machine interface (MMI) code in the embedded flash offer direct control of volume, on/off and airing switches, LED indication, and power management. The reference hardware provides the Microtune wireless voice circuit mounted on plastics with the speaker, microphone, control switches, LED antenna, a lithium polymer battery, and a separate battery charger circuit. Hardware documentation includes schematic, BOM, and PCB gerber files. The Microtune PCB design has high voice quality, good class 2 range, and low power consumption. The Microtune solution is a proven platform, allowing product developers to quickly enter the Bluetooth headset market. • • • BENEFITS • • Small size eases integration into most industrial designs Low BOM count reduces component and manufacturing costs Low power consumption increases talk time • DataSheet4U.com Product Brief DataSheet 4 U .com www.DataSheet4U.com MT0750-HS HEADSET REFERENCE DESIGN PRODUCT BRIEF OPERATIONAL CHARACTERISTICS SYSTEM-ON-CHIP BLOCKS Radio LNA (receiver) Radio PA (transmitter) Baseband Microprocessor Program memory Audio CODEC Asynchronous connectionless link (ACL) data (up to 723 kbps) SCO voice (64 kbps) Power management Power consumption (ratings for complete reference design) -80 dBm sensitivity Four-level RSSI control Class 2 -34 to +5 dBm 8-step power control Bluetooth version 1.1 Enhanced 8051 with configurable 8-bit ports 64 kB flash containing: • BT 1.1 full protocol stack • BT 1.1 headset profile • Configurable MMI G711 8-bit full duplex CODEC BLUETOOTH VOICE APPLICATIONS INTEROPERABILITY DEVICE TYPE DEVICE PART NUMBER Ericsson T39 Ericsson T68 Ericsson R520m Ericsson T68i Nokia 6310 Microtune MT1750AG Mobile phones Audio gateway Rx LNA Antenna Balun PA VCO PLL Filter GMSK Modem 24MHz Crystal Lithium Polymer Battery 3.7V/150mAh BLUETOOTH PACKET PROCESSING DM1/DH1, DM3/DH3, DM5/DH5, AUX1 Tx UART0/SPI UART1/SPI PCM Audio CODEC 8051 Processor OCI GPIOs Switch – On/Off/Pairing Baseband RAM FLASH 64kB 3V Regulator HV1, HV2, HV3, DV Sniff, park, and hold power saving modes Block power control Low voltage battery detection HV3 talk 43 mA Page scan: 1.5 mA Standby: 100 µA UART Programing & Test Interface Charging Circuit Interface RAM JTAG Programing & Test Interface Speaker Switch – Volume Up/Down Indication LED(s) Battery Voltage Comparator Microphone I/O PORTS Analog audio port Audio CODEC supports: • PCM A-Law, µ-Law, and CVSD • Microphone and speaker volume control • Single-ended or differential operation MT0750 chip: 2 x UART/SPI channels MT0750-RDHS reference design: UART1 available for programming and test MT0750 chip: 28 available GPIOs MT0750-RD-HS01 reference design: 4 GPIOs used: • Power on/off/pair • Volume up/down • LED indication • Battery detection Programming and test interference 4-pin IEEE-1149.1 Preliminary MT0750-HS Block Diagram Serial ports et4U.com SOC control ports DataSheet4U.com JTAG port PHYSICAL CHARACTERISTICS PACKAGING MT0750 BGA MT0750-HS PCB (Rev 4) (custom PCBs available on contract) 8 x 8 x 1.4 mm 64 balls 0.8 mm pitch 14.6 x 17.3 mm FR4 (4-layer, double-sided) MT0750-HS Headset-on-Chip mounted on Microtune reference circuit.
