1. Description
The GPS baseband processor ATR0622P includes a 16-channel GPS correlator and is based
on the ARM7TDMI processor core.
This processor has a high-performance 32-bit RISC architecture and very low power consump-
tion. In addition, a large number of internally banked registers result in very fast exception
handling, making the device ideal for real-time control applications. The ATR0622P has two
USART and an USB device port. This port is compliant with the Universal Serial Bus (USB) V2.0
full-speed device specification.
The ATR0622P includes full GPS firmware, licensed from u-blox AG, which performs the basic
GPS operation, including tracking, acquisition, navigation and position data output. For normal
PVT (Position/Velocity/Time) applications, there is no need for off-chip Flash memory or ROM.
The firmware supports e.g. the NMEA® protocol (2.1 and 2.3), a binary protocol for PVT data,
configuration and debugging, the RTCM protocol for DGPS, SBAS (WAAS, EGNOS and MSAS)
and A-GPS (aiding) it is also possible to store the configuration settings in an optional external
EEPROM.
The ATR0622P is manufactured using Atmel®’s high-density CMOS technology. By combining
the ARM7TDMI microcontroller core with on-chip SRAM, 16-channel GPS correlator, and a wide
range of peripheral functions on a monolithic chip, the ATR0622P provides a highly flexible and
cost-effective solution for GPS applications.

2. Architectural Overview
2.1
Description
The ATR0622P architecture consists of two main buses, the Advanced System Bus (ASB) and
the Advanced Peripheral Bus (APB). The ASB is designed for maximum performance. It inter-
faces the processor with the on-chip 32-bit memories. The APB is designed for accesses to
on-chip peripherals and is optimized for low power consumption. The AMBA™ Bridge provides
an interface between the ASB and the APB.
An on-chip Peripheral Data Controller (PDC2) transfers data between the on-chip USARTs/SPI
and the on-chip and off-chip memories without processor intervention. Most importantly, the
PDC2 removes the processor interrupt handling overhead and significantly reduces the number
of clock cycles required for a data transfer. It can transfer up to 64K contiguous bytes without
reprogramming the starting address. As a result, the performance of the microcontroller is
increased and the power consumption reduced.
The ATR0622P peripherals are designed to be easily programmable with a minimum number of
instructions. Each peripheral has a 16 Kbyte address space allocated in the upper 3 Mbyte of
the 4 Gbyte address space. (Except for the interrupt controller, which has 4 Kbyte address
space.) The peripheral base address is the lowest address of its memory space. The peripheral
register set is composed of control, mode, data, status, and interrupt registers.
To maximize the efficiency of bit manipulation, frequently written registers are mapped into three
memory locations. The first address is used to set the individual register bits, the second resets
the bits, and the third address reads the value stored in the register. A bit can be set or reset by
writing a “1” to the corresponding position at the appropriate address. Writing a “0” has no effect.
Individual bits can thus be modified without having to use costly read-modify-write and complex
bit-manipulation instructions.
All of the external signals of the on-chip peripherals are under the control of the Parallel I/O
(PIO2) Controller. The PIO2 Controller can be programmed to insert an input filter on each pin or
generate an interrupt on a signal change. After reset, the user must carefully program the PIO2
Controller in order to define which peripheral signals are connected with off-chip logic.
The ARM7TDMI processor operates in little-endian mode on the ATR0622P GPS Baseband.
The processor's internal architecture and the ARM and Thumb instruction sets are described in
the ARM7TDMI datasheet.
The ARM standard In-Circuit Emulator (ICE) debug interface is supported via the JTAG/ICE port
of the ATR0622P.
For features of the ROM firmware, refer to the software documentation available from u-blox AG,
Switzerland.

Setting GPSMODE0 to GPSMODE12
The start-up configuration of a ROM-based system without external non-volatile memory is
defined by the status of the GPSMODE pins after system reset. Alternatively, the system can be
configured through message commands passed through the serial interface after start-up. This
configuration of the ATR0622P can be stored in an external non-volatile memory like EEPROM.
Default designates settings used by ROM firmware if GPSMODE configuration is disabled
(GPSMODE0 = 0).

For all GPS receivers the sensitivity depends on the integration time of the GPS signals. There-
fore there is a trade-off between sensitivity and the time to detect the GPS signal (Time to first
fix). The three modes, “Fast Acquisition”, “Normal” and “High Sensitivity”, have a fixed integra-
tion time. The “Normal” mode, recommended for the most applications, is a trade off between
the sensitivity and TTFF. The “Fast Acquisition” mode is optimized for fast acquisition, at the
cost of a lower sensitivity. The “High Sensitivity” mode is optimized for higher sensitivity, at the
cost of longer TTFF. The “Auto” mode adjusts the integration time (sensitivity) automatically
according to the measured signal levels. That means the receiver with this setting has a fast
TTFF at strong signals, a high sensitivity to acquire weak signals but some times at medium sig-
nal level a higher TTFF as the “Normal” mode. These sensitivity settings affect only the startup
performance not the tracking performance.
3.3.3
Serial I/O Configuration
The ATR0622P features a two-stage I/O message and protocol selection procedure for the two
available serial ports. At the first stage, a certain protocol can be enabled or disabled for a given
USART port or the USB port. Selectable protocols are RTCM, NMEA and UBX. At the second
stage, messages can be enabled or disabled for each enabled protocol on each port. In all con-
figurations discussed below, all protocols are enabled on all ports. But output messages are
enabled in a way that ports appear to communicate at only one protocol. However, each port will
accept any input message in any of the three implemented protocols

ATR0622P
Both USART ports and the USB port accept input messages in all three supported protocols
(NMEA, RTCM and UBX) at the configured baud rate. Input messages of all three protocols can
be arbitrarily mixed. Response to a query input message will always use the same protocol as
the query input message. The USB port does only accept NMEA and UBX as input protocol by
default. RTCM can be enabled via protocol messages on demand.
In Auto Mode, no output message is sent out by default, but all input messages are accepted at
any supported baud rate. Again, USB is restricted to only NMEA and UBX protocols. Response
to query input commands will be given the same protocol and baud rate as it was used for the
query command. Using the respective configuration commands, periodic output messages can
be enabled.

USB Power Mode
For correct response to the USB host queries, the device has to know its power mode. This is
configured via GPSMODE7. If set to bus powered, an upper current limit of 100 mA is reported
to the USB host; that is, the device classifies itself as a “low-power bus-powered function” with
no more than one USB power unit load.

Active Antenna Supervisor
The two pins P0/NANTSHORT and P15/ANTON plus one pin of P25/NAADET0/MISO or
P14/NAADET1 are always initialized as general purpose I/Os and used as follows:
• P15/ANTON is an output which can be used to switch on and off antenna power supply.
• Input P0/NANTSHORT will indicate an antenna short circuit, i.e. zero DC voltage at the
antenna, to the firmware. If the antenna is switched off by output P15/ANTON, it is assumed
that also input P0/NANTSHORT will signal zero DC voltage, i.e. switch to its active low state.
• Input P25/NAADET0/MISO or P14/NAADET1 will indicate a DC current into the antenna. In
case of short circuit, both P0 and P25/P14 will be active, i.e. at low level. If the antenna is
switched off by output P15/ANTON, it is assumed that also input P25/NAADET0/MISO will
signal zero DC current, i.e. switch to its active low state. Which pin is used as NAADET (P14
or P25) depends on the settings of GPSMODE11 and GPSMODE10 (see Table 3-14 on
page 13).

Connecting an Optional Serial EEPROM
The ATR0622P offers the possibility to connect an external serial EEPROM. The internal ROM
firmware supports to store the configuration of the ATR0622P in serial EEPROM. The pin
P16/NEEPROM signals the firmware that a serial EEPROM is connected with the ATR0622P.
The 32-bit RISC processor of the ATR0622 accesses the external memory with SPI (Serial
Peripheral Interface). Atmel recommend to use 32 Kbit 1.8V serial EEPROM, e.g. the Atmel
AT25320AY1-1.8. Figure 3-3 shows an example of the serial EEPROM connection.

4. Power Supply
The baseband IC is supplied with four distinct supply voltages:
• VDD18, the nominal 1.8V supply voltage for the core, the RF-I/O pins, the memory interface
and the test pins and all GPIO-pins not mentioned in next item.
• VDDIO, the variable supply voltage within 1.8V to 3.6V for following GPIO-pins: P1, P2, P8,
P12, P14, P16, P17, P18, P19, P20, P21, P23, P24, P25, P26, P27 and P29 In input mode,
these pins are 5V input tolerant.
• VDD_USB, the power supply of the USB pins: USB_DM and USB_DP.
• VBAT18 to supply the backup domain: RTC, backup SRAM and the pins NSLEEP, NSHDN,
LDO_EN, VBAT18, P9/EXTIN0, P13/EXTINT1, P22/RXD2 and P31/RXD1 and the 32kHz
oscillator. In input mode, the four GPIO-pins are 5V input tolerant.
Figure 4-1, Figure 4-2, and Figure 4-3 show examples of the wiring of ATR0622P power supply.

The baseband IC contains a built in low dropout voltage regulator LDO18. This regulator can be
used if the host system does not provide the core voltage VDD18 of 1.8V nominal. In such case,
LDO18 will provide a 1.8V supply voltage from any input voltage VDD between 2.3V and 3.6V.
The LDO_EN input can be used to shut down VDD18 if the system is in standby mode.
If the host system does however supply a 1.8V core voltage directly, this voltage has to be con-
nected to the VDD18 supply pins of the baseband IC. LDO_EN must be connected to GND.
LDO_IN can be connected to GND. LDO_OUT must not be connected.
A second built in low dropout voltage regulator LDOBAT provides the supply voltage for the RTC
and backup SRAM from any input voltage LDOBAT_IN between 2.3V and 3.6V or from VBAT
between 1.5V and 3.6V. The backup battery connected to VBAT is only discharged if the supply
connected to LDOBAT_IN is shut-down.
Only after VDD18 has been supplied to ATR0622P the RTC section will be initialized properly. If
only VBAT is applied first, the current consumption of the RTC and backup SRAM is
undetermined.
