LC76GABMD Features
- ⚫ The single-band, multi-constellation GNSS module series features a high-performance, high reliability positioning engine facilitating fast and precise GNSS positioning.
- ⚫ The LC76G (AB) is designed to meet standard application requirements while operating at 3.3 V, while the LC76G (PA) and the LC76G (PB) are super low power consumption variants operating at 3.3 V and 1.8 V respectively.
- ⚫ Supported serial communication interfaces: UART, SPI* and I2C.
- ⚫ Supported advanced power saving modes: Backup mode and ALP mode.
- ⚫ The embedded low-power algorithms make the LC76G series module suitable for different application scenarios.
- ⚫ EASY technology facilitates achieving a faster Time to First Fix (TTFF) in either hot or warm start.
- ⚫ The integrated flash memory provides the capacity for storing user-specific configurations and future firmware upgrades.
The LC76G is a series of SMD type modules with a compact form factor of 10.1 mm × 9.7 mm × 2.4 mm. They can be embedded in your applications through 18 LCC pins and 10 LGA pins.
