1.1 Features
Equipped with an OKI SEMICONDUCTOR original 8-bit CPU nX-U8/100, the ML610Q346 is a high-performance
8-bit CMOS microcontroller that integrates a wide variety of peripherals such as an op-amp, 12-bit A/D converter, timer,
synchronous serial port, UART, 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 microcontroller is also equipped with a flash memory that has achieved low voltage and low power consumption (at
read) equivalent to mask ROMs, so it is best suited to battery-driven applications such as cellular phones. In addition,
it has an on-chip debugging function, which allows software debugging/rewriting with the LSI mounted on the board.
CPU
8-bit RISC CPU (CPU name: nX-U8/100)
Instruction system: 16-bit instructions
Instruction set: Transfer, arithmetic operations, comparison, logic operations, multiplication/division, bit
manipulations, bit logic operations, jump, conditional jump, call return stack manipulations, arithmetic shift,
and so on
On-Chip debug function

Internal 1 Kbyte RAM (1024 8 bits)
Interrupt controller
2 non-maskable interrupt sources (Internal source: 1, External source: 1)
18 maskable interrupt sources (Internal source: 10, External source: 8)
Time base counter
Low-speed time base counter 1 channel
High-speed time base counter 1 channel
Watchdog timer
Generates a non-maskable interrupt upon the first overflow and a system reset occurs upon the second
Free running
Overflow period: 4 types selectable (125ms, 500ms, 2s, and 8s)
Timers
8 bits 2ch (16-bit configuration available) |
