WL102B/IG/TP1R 100 pin package
WL102BC/PR/FP1R 144 pin package
The WL102B is a highly integrated CMOS wireless data
controller designed to dramatically reduce the cost of
radio data applications. It works with the WL600C RF IF
chip and WL800 synthesiser chip to offer a complete
solution for a frequency hopping, spread spectrum radio
in the 2.4 to 2.45GHz ISM band.
Its flexible design means that it can also be used in a
wide range of other applications using a range of "proc-
essor", protocols and additional memory options as well
as radios at other frequencies.

WL102 System Overview
The WL102 is a highly integrated digital wireless
transceiver controller suitable for controlling multiple
channel radios with data rates up to 1Mbit/s 2-level data or
2Mbit/s 4-level data. It has been designed to interface easily
with the WL600 and WL800 radio transceiver chips.
The use of low power synchronous on chip RAM and
selective power down of system blocks makes the WL102
ideally suited to power sensitive applications. Also the
WL102 can be operated from 3V or 5V supply rails with level
translation between the Host and MAC system built in to the
Host Interface. A minimum configuration of the WL102 with
a 64Kbyte external ROM for code storage makes it ideal for
small footprint applications, and the option of 100 pin or 144
pin TQFP 1mm packages make it suitable for PC-Card
applications.
The 100 pin package option allow the WL102 to be used in
the lowest cost solution. This includes all the internal blocks
of the WL102 hardware plus the option of an external
processor, to replace the internal 8051 core, and the
external system RAM and / or other peripherals on the
processor bus. The 144 pin package includes the 100 pin
features plus the option of using an external data buffer
RAM (up to 64K), to replace the internal 6.4K buffer RAM,
and the option of using the parallel synthesiser load pins the
are active in DE6003 mode of the CCB block, the Datasheet
DS4837 should be checked for further information on this
option.
The Communications Control Block performs transmit and
receive operations directly to the buffer RAM so minimising
the load on the MAC system processor. A minimum
controller system configuration would be the WL102 plus
an external code memory device.
WL102 Hardware Blocks
System Processor
The WL102 contains an embedded processor, identical in
operation to an industry standard 8051 microcontroller,
with the exception that the internal data memory is
increased from 128 to 256 bytes.
System busses and strobes allow the 8051 to access the
full 64 Kbytes of external code memory. Internal
connections exist to the processor's two interrupt inputs,
and to the two timer inputs. Two I/O port pins are internally
connected to blocks within the WL102, whilst four of the
remaining I/O port pins are brought out to external pins,
including the serial receive and transmit port pins. Internal
address decoding provides access to the other blocks of
the device, with 36 Kbytes of the processor's 64 Kbytes
address range being unassigned and available for the
addition of external peripheral devices.
The 8051 demultiplexed address and data bus are
available externally to allow for the addition of extra
memory or other peripheral devices.
It is envisaged that the WL102 hardware will allow the
development of a wireless network to the Media Access
Layer of the IEEE model for networking, with the addition
of an LLC layer providing the equivalent of the Data Link
layer of the ISO network model. In such a system the Host
interface buffer RAM would provide the boundary between
the LLC layer running on the Host and the MAC layer on the
internal WL102 8051 processor, or an optional external
MAC system processor.
Figure 1 shows the internal architecture of the WL102.
The WL102 provides an interface between a Host system,
such as a PC or PDA, which can be a PC-Card interface or
an 8 bit microprocessor bus, and an interface designed for
use with the DE6038 (WL600/WL800) radio transceiver.
The host interface provides a buffer and interrupt signalling
mechanisms between the Host and Mac system
processors. The MAC system processor is required to
provide the timing and control functions of Media Access
Control.
The 8051 is clocked at the internal system clock frequency
of 10MHz.
If additional processing power is required for a particular
application the WL102 may also be used with an external
processor instead of the internal 8051. This external
processor also accesses the WL102 blocks via the internal
address decode. Interrupt and Counter outputs are
brought to external pins and two control signals must also
be provided to the WL102.
Data RAM
The WL102 contains 4 Kbytes of static RAM which the
processor may use for variable storage etc. If additional
storage space is required, an external static RAM may also
be used, and mapped to an unused area of the WL102
memory map.
