ML610Q305/306
8-bit Microcontroller with Voice Output Function
GENERAL DESCRIPTION
Ÿ Please see the "Notes" and the "Notes for product usage" in this document.
Equipped with a 8-bit CPU nX-U8/100, the ML610Q305/306 is a high-performance 8-bit CMOS microcontroller that integrates
a wide variety of peripherals such as timer, synchronous serial port, successive approximation type 10-bit A/D converter and
voice output function. The nX-U8/100 CPU is capable of executing instructions efficiently on a
one-instruction-per-clock-pulse basis through parallel processing by the 3-stage pipelined architecture. The ML610Q305/306
is also equipped with a flash memory* that has achieved low voltage and low power consumption (at read) equivalent to mask
ROM, so it is best suited to battery-driven applications such as alarm and portable devices. In addition, it has an on-chip
debugging function, which allows software debugging/rewriting with the LSI mounted on the board.
