2.0 Product overview
The DECT transceiver module HW 86010 is a highly versatile and powerful
engine for popular and advanced DECT applications. It provides both RF
and baseband signal processing as well as a complete DECT protocol
stack.
2.1 General description
Built around a 55 MHz high-speed µC core the architecture of the HW
86010 features a full set of useful interfaces for best support of voice and
data services in various environments.
These include RS-232 for circuit data transmission, PCM interface to
connect to standard ISDN or PBX systems, I²C for auxiliary functions and
analogue input/output for voice. Additional general purpose I/Os plus an
accessible bus interface make the HW 86010 ideally suited for automation
and control applications with specific I/O requirements.
The RF section of the HW 86010 comprises a single-blind-slot radio, fully
compliant with EN 300 175-2. It offers improved functionality. Three
antenna connections allow flexible configurations. E.g. use of two antennas
for standard antenna diversity, together with an additional directional
antenna. Switching between antennas is performed under software control.
The DECT protocol stack has been implemented as firmware running on
the µC of the HW 86010. Please consult your Firmware manual for a
detailed description of the Firmware features.
The ultra-compact and low-voltage design make the HW 86010 optimally
suited for battery powered devices.

3.2 Electrical characteristics
3.2.1 Supply voltage V3P3
min. max.
Absolute maximum rating -0.5V +3.63V
Operating +3.0V +3.6V
Ripple +/-30mV
Voltage V3P3 is used as power supply for the baseband section of HW
86010. It is the reference voltage for all digital I/Os.
The current consumption on V3P3 depends on the power management.
Power management only applies to the PT, not to the FT. The PT may enter
a sleep mode whilst the FT is always active.
During firmware download the current consumption is higher, because
additional power is needed for writing the Flash memory
Mode average I3P3 peak I3P3
Sleep mode (PT only) 9mA 50mA
Active mode 40mA 50mA
Firmware download 40mA 90mA
All values are approximate figures measured under typical operating
conditions (20°C).

3.2.2 Supply voltage VBATP
min. max.
Absolute maximum rating -0.5V +5.5V
Operating +3.3V +4.7V
Ripple +/-100 mV
Voltage VBATP is used as power supply for the radio section of HW 86010.
Mode average IBATP peak IBATP
Sleep mode (PT only) 3mA 300mA
Scan mode (PT only) 60mA 300mA
Idle mode (FT only) 50mA 400mA
1 traffic bearer 50mA 400mA
4 traffic bearers 110mA 400mA
All values are approximate figures measured under typical operating
conditions.
IBATP
100mA/div
t2ms/div
Figure 7: Typical IBATP bursts (multi-bearer connection active)
The current consumption on VBATP depends on the power management
and on the number of active traffic bearers. Power management only
applies to the PT, not to the FT. The PT may enter a sleep mode whilst the
FT is always active. If no communication is active, the FT operates in idle
mode. In this mode it sends out a dummy bearer.

Even in sleep mode a PT stays synchronised to the FT. In case
synchronisation is lost, the PT scans all DECT channels until it finds a
suitable FT. In scan mode the PT requires more power.
Caution: When a PT does not receive a valid FT it enters scan mode. This
may reduce stand-by time of battery-powered devices. Try to avoid this
situation.
