1. Serial Interface
1.1 USB Interface
BTM-860 has a full-speed (12Mbps) USB interface for communicating with other compatible digital devices.
The USB interface on BTM-860 acts as a USB peripheral, responding to requests from a master host controller.
BTM-860 contains internal USB termination resistors and requires no external resistor matching.
BTM-860 supports the Universal Serial Bus Specification, Revision v2.0 (USB v2.0 Specification), supports
USB standard charger detection and fully supports the USB Battery Charging Specification , available from
http://www.usb.org. For more information on how to integrate the USB interface on BTM-860 see the Bluetooth and
USB Design Considerations Application Note.
As well as describing USB basics and architecture, the application note describes:
■ Power distribution for high and low bus-powered configurations
■ Power distribution for self-powered configuration, which includes USB VBUS monitoring
■ USB enumeration
■ Electrical design guidelines for the power supply and data lines, as well as PCB tracks and the effects of
ferrite beads
■ USB suspend modes and Bluetooth low-power modes:
- Global suspend
- Selective suspend, includes remote wake
- Wake on Bluetooth, includes permitted devices and set-up prior to selective suspend
- Suspend mode current draw
- PIO status in suspend mode
- Resume, detach and wake PIOs
■ Battery charging from USB, which describes dead battery provision, charge currents, charging in suspend
modes and USB VBUS voltage consideration
■ USB termination when interface is not in use
■ Internal modules, certification and non-specification compliant operation
1.2 Programming and Debug Interface
BTM-860 provides a debug SPI interface for programming, configuring (PS Keys) and debugging the BTM-860.
Access to this interface is required in production. Ensure the 4 SPI signals and the SPI line are brought out to either
test points or a header. To use the SPI interface, the SPI line requires the option of being pulled high externally.
2. interfaces
2.1 Analogue I/O Ports, AIO
BTM-860 has 2 general-purpose analogue interface pin, AIO[0] & AIO[1]. Typically, this connects to a thermistor for
battery pack temperature measurements during charge control.
2.2 LED Drivers
BTM-860 includes a 3-pad synchronised PWM LED driver for driving RGB LEDs for producing a wide range
of colours. All LEDs are controlled by firmware.
