MB90340 Series
■ FEATURES
• Clock
• Built-in PLL clock frequency multiplication circuit
• Selection of machine clocks (PLL clocks) is allowed among frequency division by two on oscillation clock, and
multiplication of 1 to 6 times of oscillation clock (for 4 MHz oscillation clock, 4 MHz to 24 MHz).
• Operation by sub-clock (up to 50 kHz : 100 kHz oscillation clock divided two) is allowed. (devices without S-
suffix only)
• Minimum execution time of instruction : 42 ns (when operating with 4-MHz oscillation clock, and 6-time multi-
plied PLL clock).
• 16 Mbyte CPU memory space
• 24-bit internal addressing
• Instruction system best suited to controller
• Wide choice of data types (bit, byte, word, and long word)
• Wide choice of addressing modes(23 types)
• Enhanced multiply-divide instructions and RETI instructions
• Enhanced high-precision computing with 32-bit accumulator
• Instruction system compatible with high-level language (C language) and multitask
• Employing system stack pointer
• Enhanced various pointer indirect instructions
• Barrel shift instructions
• Increased processing speed
• 4-byte instruction queue
• Powerful interrupt function
• Powerful 8-level, 34-condition interrupt feature
• Up to 16 external interrupts are supported
• Automatic data transfer function independent of CPU
• Expanded intelligent I/O service function (EI2OS) : up to 16 channels
• DMA : up to 16 channels
• Low power consumption (standby) mode
• Sleep mode (a mode that halts CPU operating clock)
• Time-base timer mode (a mode that operates oscillation clock, sub clock, time-base timer and clock timer only)
• Watch mode (a mode that operates sub clock and clock timer only)
• Stop mode (a mode that stops oscillation clock and sub clock)
• CPU blocking operation mode
• Process
• CMOS technology
• I/O port
• General-purpose input/output port (CMOS output)
- 80 ports (devices without S-suffix)
- 82 ports (devices with S-suffix)
• Timer
• Time-base timer, clock timer, watchdog timer : 1 channel
• 8/16-bit PPG timer : 8-bit X 16 channels, or 16-bit X 8 channels
• 16-bit reload timer : 4 channels
• 16- bit input/output timer
- 16-bit free run timer : 2 channel (FRT0 : ICU 0/1/2/3, OCU 0/1/2/3, FRT1 : ICU 4/5/6/7, OCU 4/5/6/7)
