Overview
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 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™.
Feature 2High-speed 12-bit successive approximation A/D converter that contributes to high-accuracy sensor measurement
High-speed (Min 1.375μs / Ch.) A/D conversion is possible, and the number of times of sensing can be increased in a short period, contributing to improving measurement accuracy.

Applications
The ML62Q2700 group takes over the “Safety Function” of the ML62Q1000 series and also has class-leading power consumption and a high-speed 12-bit successive approximation A/D that contributes to improving sensor measurement accuracy. Therefore, the ML62Q2700 group is ideal for industrial such as measuring equipment requiring high accuracy analog measurement, and home appliances such as water heaters, and rice cookers.
speech synthesis utility (Speech LSI Tools)
Run the 'Speech LSI Tools' program on a PC to create sound code data using a ML62Q2700 group.
Speech LSI Tools include a Wave Editor that makes it easy to change (i.e.fade in/out), cut, and connect original sound data (WAVE files) as well as a Speech LSI Utility capable of editing phrases and converting WAVE files to the HQ-ADPCM and ADPCM2 formats.
