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.

Key features

  • 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.

The display component supports MIPI-DSI and serial interfaces. It includes 2D capabilities of true color, per pixel alpha channel and anti-aliasing fonts, plus 1-bit index color to save memory and computing power. The camera component supports DDR mode with a maximum clock rate of 48MHz, up to VGA.
