MediaTek MT2523 product family (MT2523D/MT2523G) is based around a highly integrated system in package (SiP) design that contains a micro controller unit, a low power GNSS chip (MT2523G), dual mode Bluetooth, and a power management unit (PMU). The micro controller unit is an ARM Cortex-M4F MCU with integrated 4MB PSRAM and 4MB flash memory. MT2523 also supports interfaces such as UART, I2C, SPI, I2S, PWM, SDIO, MSDC, USB, PCMIF, ADC and dual digital MIC.
High integration with RF+MCU+Memory
Low power mode with RTC
Supports multiple frequency and voltage modes to achieve an improved and extended battery life while maintaining high performance
Fast switching time from sleep mode to active mode under 10μs
The GNSS companion chip is a multi-GNSS RF SoC aimed to achieve the industry’s highest level of sensitivity, accuracy and Time-to-First-Fix (TTFF) with lowest power consumption. It supports various location and navigation applications, including autonomous GPS, GLONASS, GALILEO, BEIDOU, SBAS ranging (WAAS, EGNOS, GAGAN, and MSAS), QZSS, DGPS (RTCM) and Assisted GPS (A-GPS). It also includes up to 12 multi-tone active interference cancellers.
The Bluetooth subsystem supports Bluetooth 2.1 and Bluetooth 4.2 Low Energy (dual mode). It contains the Bluetooth radio, baseband and link controller.
