This LSI is a high-performance 8-bit CMOS microcontroller into which rich peripheral circuits, such as timers, PWM, UART, I2 C bus interface (master/slave), synchronous serial port, voltage level supervisor analog comparators and 10-bit successive approximation type A/D converter, are incorporated around 8-bit CPU nX-U8/100. The CPU nX-U8/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by pipe line architecture parallel processing. The Flash ROM that is installed as program memory, and the on-chip debug function that is installed, enable program debugging and programming on customer’s 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
- Minimum instruction execution time: 30.5µs (@32.768kHz system clock) 0.122µs (@8.192MHz system clock)
- Internal memory
- ML610Q112: Flash memory : Internal 32Kbyte Flash memory (16K x 16bit) for program including unusable 32byte test data area. Internal 4Kbyte Flash memory (2K x 16bit) for data.
- SRAM : Internal 4Kbyte data RAM (4K x 8bit)
- Flash Memory operating condition and specification
- Interrupt controller
- 1 non-maskable interrupt source (Internal source: 1(WDT))
- 30 maskable interrupt sources (Internal sources: 23, External source: 7)
- Time base counter (TBC)
- Low-speed time base counter: 1 channel
- High-speed time base counter: 1 channel (This time base counter is divided by 1-16, then it can be used as a clock of the Timer and PWM.) FEDL610Q111-01 ML610Q112 2/26
- Watchdog timer (WDT)
- Non-maskable interrupt and reset (Non-maskable interrupt is generated by the first overflow, and reset is generated by the second overflow)
- Free running
- Overflow period: 7 types selectable by software (23.4ms, 31.25ms, 62.5ms, 125ms, 500ms, 2s, and 8s)
- Timer
- 8-bit x 6 channels (16-bit configuration available, 16-bit x 3ch)
- Supports auto reload timer mode/One shot timer mode
- Timer count start/stop by software or external input trigger (Timer function with external trigger input supports for only 2ch. Selectable external pins/analog comparator output as an exeternal trigger.)
- The effective minimum pulse width of the external trigger input: Timer clock 3f (about 183 ns @ 16.384 MHz)
- Allows measurement of pulse width etc. using an external trigger input.
- 8-selectable clock frequency as counter clock per channel
