... Due to the fully integrated design, just an RF SAW filter, a GPS XTAL (no TCXO) and blocking capacitors are required to realize a stand-alone GPS functionality. The ATR0630 includes a complete GPS firmware, licensed from u-blox AG, which performs the GPS operation, including tracking, acquisition, navigation and position data output. For normal PVT (Position/Velocity/Time) applications, there is no need for external Flash- or ROM-memory ...

... Especially, due to its fast search engine and GPS accelerator, the ATR0630 only needs a GPS crystal (XTAL resonator for the integrated crystal oscillator of the ATR0630. This saves the considerable higher cost of a TCXO which is required for competi- tor’s systems. Also, as the powerful standard software is available in ROM, no external flash memory is needed ...

... Connecting an Optional Serial EEPROM The ATR0630 offers the possibility of connecting an external serial EEPROM. The internal ROM firmware supports storing the configuration of the ATR0630 in serial EEPROM. The pin P16/NEEPROM signals the firmware that a serial EEPROM is connected to the ATR0630. The ATR0630’s 32-bit RISC processor accesses the external memory via SPI (serial peripheral inter- face). For best results, use a 32-Kbit 1.8V serial EEPROM such as Atmel’ ...

... Power Supply The ATR0630 is supplied with six distinct supply voltages: • The power supplies for the RF part (VCC1, VCC2, VBP) within 2.7V to 3.3V. • VDIG, the 1.8V supply of the digital pins of the RF part (SIGHI, SIGLO and CLK23). VDIG should be connected to VDD18. • VDD18, the nominal 1.8V supply voltage for the core, the I/O pins, the memory interface and the test pins and all GPIO pins not mentioned in next item. • ...

... NSHDN 1. 3.6V The ATR0630 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 RTC section will be initialized properly if VDD18 is supplied first to the ATR0630. If VBAT is applied first, the current consumption of the RTC and backup SRAM is undetermined.
