      Build-in Speech Playback Function ML62Q2000 Series / ML62Q2700 Group (U16)

      Overview

      ML62Q2700 group System Block Diagram

      The ML62Q2700 group CMOS MCUs utilize LAPIS TECHNOLOGY™ 's original 16-bit RISC U16 Core to achieve superior performance.
      This group is equipped with program memory(Flash memory), data memory(RAM), data Flash (Erase unit:128byte, Write unit:1byte), and rich peripheral functions such as the multiplier/divider, CRC generator, Clock generator, Timer, General Purpose Ports, UART, Synchronous serial port, I2C bus interface unit(Master, Slave),
      Voltage Level Supervisor(VLS), High-speed Successive approximation type 12bit A/D converter, LCD driver, Speech playback function, Safety function (IEC60730/60335 Class B), and so on.
      The built-in on-chip debug function enables debugging and programming the software. Also, the ISP (In-System Programming) function supports the Flash programming in the production line.

      Product Features

      Feature 1Built-in hardware-based speech playback function facilitates speech playback without the need to purchase middleware.

      Built-in hardware-based speech playback function facilitates speech playback without the need to purchase middleware

      Built-in hardware-based ADPCM speech playback function that can reduce the CPU load when playing guidance and sound effects.
      Facilitates Speech Playback by calling the library function for playing sound provided by LAPIS TECHNOLOGY™.
