s 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
