■ 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
