ML610421
8-bit Microcontroller with a Built-in LCD driver
FEDL610421-02
Issue Date: Feb.9, 2015
GENERAL DESCRIPTION
This LSI is a high-performance 8-bit CMOS microcontroller into which rich peripheral circuits, such as synchronous serial port,
UART, I2C bus interface (master), melody driver, battery level detect circuit, RC oscillation type A/D converter, 12-bit
successive approximation type A/D converter, and LCD driver, 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 3-stage pipe
line architecture parallel procesing. This LSI operates in both high/low-speed mode and power-saving mode, it is most
suitable for battery operated products.
FEATURES
• 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
− Minimum instruction execution time
30.5 µs (@32.768 kHz system clock)
0.24 4µs (@4.096 MHz system clock)
• Internal memory
− Internal 32KBbyte mask ROM (16K×16 bits) (including unusable 1KByte TEST area)
− Internal 1KByte Data RAM (1024×8 bits), 1KByte Display Allocation RAM (1024 x 8bit)
− Internal 100Byte RAM for display
• Interrupt controller
− 2 non-maskable interrupt sources (Internal source: 1, External source: 1)
− 20 maskable interrupt sources (Internal sources: 16, External sources: 4)
• Time base counter
− Low-speed time base counter ×1 channel
Frequency compensation (Compensation range: Approx. −488ppm to +488ppm. Compensation accuracy: Approx.
0.48ppm)
− High-speed time base counter ×1 channel
• Watchdog timer
− Non-maskable interrupt and reset
− Free running
− Overflow period: 4 types selectable (125ms, 500ms, 2s, and 8s)
• Timers
− 8 bits × 4 channels (Timer0-3: 16-bit x 2 configuration available by using Timer0-1 or Timer2-3)
− Clock frequency measurement mode (in one channel of 16-bit configuration using Timer2-3)
