Note: Minimum/maximum limits are at +25°C ambient temperature, unless otherwise specifiedDescriptionThe GPS baseband processor ATR0625 includes a 16-channel GPS correlator and is based on the ARM7TDMI® processor core.
This ATR0625 processor has a high-performance 32-bit RISC architecture and very low power consumption. 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 ATR0625 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 ATR0625 includes full GPS SuperSense™ 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 the possibility to store the configuration settings in an optional external EEPROM. For customer-specific applications, a Software Development Kit is available.
The ATR0625 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 ATR0625 provides a highly flexible and cost-effective solution for GPS applications.
