■ DESCRIPTION

The MB90860A-series is Fujitsu 16-bit general-purpose microcontroller which enhances each kind of timers and communication macros. With the new 0.35 µm CMOS technology, Fujitsu now offers 128 Kbytes on-chip FLASHROM program memory. An internal voltage booster removes the necessity for a second programming voltage.

■ 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 by 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 multiplied 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

• Extended 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
