Description
The PER1220 is a ready to market Class 2 Bluetooth Modul Solution. It can easy implemented in any
electronical device to add Bluetooth connectivity. In standard configuration the module includes an 8
Mbit Flash, a radio solution, interfaces to antenna and application together with signalling at RFComm
level. The Module supports both voice and data transmissions.
Since the PER1220 is already a qualified product according to Bluetooth Specification V1.2 the
requested cost and time afford for qualification is kept to a minimum.
The standard software contains a full Bluetooth Protocol Stack up to RFComm and a serial port
application. For example this on-chip-application can support your cable-replacement.

5 Radio Characteristics
The PER1220 Bluetooth Module is qualified according to Bluetooth Specification V 1.2. So its radio
characteristics are equal or better as requested in the specification.
Please contact PRETTL support staff for more detailed information.
6 PER1220 Bluetooth Software Stack
PER1220 comes with a Bluetooth stack firmware running in the internal RISC microcontroller. This is
compliant to the Bluetooth Specification V1.2
The Bluetooth Module software architecture includes an on chip “Serial Port Profile” application. This

7 Device Terminal Description
7.1 Antenna
- 2.4 GHz Antenna (Z
0
= 50 Ohm)
- Min. 100 MHz Bandwidth
- Temperature range: -20 °C to + 70 °C
- A ceramic antenna requires a copper free area in all PCB layers
- Antenna gain: 0 dBi (If your antenna uses another antenna gain, you must do your own FCC
approval)
This antenna gain is mandatory for the FCC limited modular approval. See Chapter 12 “Regulatory
Statements”.
7.2 UART Interface
PER1220 Universal Asynchronous Receiver Transmitter (UART) interface provides a simple
mechanism for communicating with other serial devices using the RS232 Standard

Four signals are used to implement the UART Function as shown in figure 6. When PER1220 is
connected to another digital device UART_RX and UART_TX transfer data between the two devices.
The remaining two signals UART_CTS and UART_RTS can be used to implement RS232 hardware
flow control. Where both are active low indicators. All UART connections are implemented using
CMOS technology and have signalling levels of 0 V and 3.3 V.
UART configuration parameters, such baud rate and packet format, can optionally set

7.3 USB Interface
PER1220 contain a full speed (12 Mbit/s) USB interface, capable of driving a USB cable directly. No
external USB transceiver is required. The device operates as a USB peripheral, responding to
requests from a master host controller such a PC. Both the OHCI and the UHCI standards are
supported. The set of USB endpoints implemented behave as a specified in the USB section of the
Bluetooth Specification V1.2, part H2.
As USB is a master-slave oriented system, PER1220 only supports USB slave operation.

®
Support.
7.4 Serial Peripheral Interface
PER1220 holds the firmware and the persistent store in a flash. It can be read/write by the SPI.
Normally, this will be done by PRETTL
®
. Ask for more details
7.5 PCM
Pulse Code Modulation (PCM) is the standard method used to digitise human voice patterns for
transmission over digital communication channels. Through it’s PCM interface, PER1220 has
hardware support for continual transmission and reception of PCM data, thus reducing processor
overhead for wireless headset applications. PER1220 offers a bi-directional digital audio interface that
routes directly into the Baseband layer to the on-chip firmware. It does not pass through the HCI
protocol layer.
Hardware on PER1220 allows the data to be sent and received from a SCO connection.
Up to three SCO connections can be supported by the PCM interface at any one time.
(1)
PER1220 can operate as the PCM interface Master generating an output clock of 128, 256 or 512
kHz. When configured as PCM interface slave it can operate with an input clock up to 2048 kHz.
PER1220 is compatible with a variety of clock formats, including Long Frame Sync, Short Frame Sync
and GCI timing environments.

It support 13- or 16-bit-linear, 8-bit-
µ
-law or A-law companded sample formats at 8 ksamples/s and
can receive and transmit on any selection of three of the first four slots following PCM_SYNC. The
PCM configuration options are enabled by setting a Persistent Store Key.
PER1220 interfaces directly to PCM devices includes the following:
•
Qualcomm MSM 3000 series and MSM 5000 series CDMA Baseband devices
•
OKI MSM7705 four channel A-law and
µ
-law CODEC
•
Motorola MC145481 8-bit-A-law and
µ
-law CODEC
•
Motorola MC145483 13-bit-A-law and

-law CODEC
PER1220 is also compatible with Motorola SSi
TM
Interface
Ask for PER1220 that includes the Audio CODEC.
Note:

Subject to firmware support, contact PRETTL for details
7.6 PIO
The Parallel Input Output (PIO) Port is a general purpose I/O interface to PER1220. The port consists
of 8 programmable, bi-directional lines, PIO[7,0]
Programmable I/O lines can be accessed either via an embedded application running on PER1220 or
via private channel.

-
There are two different voltage rails inside the PER1220. One section of the module is directly
powered with 3.3 Volt input voltage. The other section is powered with 1.8 Volt. Therefore the
PER1220 includes a 1.8 V voltage regulator.
