■ DESCRIPTION

The MB90520A/520B series is a general-purpose 16-bit microcontroller designed for process control applications in consumer products that require high-speed real-time processing.

The microcontroller instruction set is based on the AT architecture of the F2MC* family with additional instructions for high-level languages, extended addressing modes, enhanced multiplication and division instructions, and a complete range of bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long word (32-bit) data.

■ FEATURES

• Clock

• Internal PLL clock multiplication circuit

• Selectable machine clock (PLL clock) : Base oscillation divided by two or multiplied by one to four (For a 4 MHz base oscillation, the machine clock range is 4 MHz to 16 MHz) .

• Sub-clock (32.768 KHz) operation available

Minimum instruction execution time : 62.5 ns (for oscillation = 4 MHz, PLL clock setting = ×4, VCC = 5.0 V)

• 16MB CPU memory space

Internal 24-bit addressing

• Instruction set optimized for controller applications

Rich data types (bit, byte, word, long-word)

Extended addressing modes (23 types)

Enhanced signed multiplication and division instructions and RETI instruction

Enhanced calculation precision using a 32-bit accumulator

• Instruction set designed for high-level language (C) and multi-tasking

System stack pointer

Enhanced pointer-indirect instructions and barrel shift instructions

• Faster execution speed

4-byte instruction queue

ROM mirror function (48 Kbytes of bank FF is mirrored in bank 00)

• Program patch function : An address match detection function (2 × addresses)

• Interrupt function

32 programmable interrupts with 8 levels

• Automatic data transmission function independent of CPU operation

Extended intelligent I/O service function (EI2OS) : Up to 16 channels

• Low-power consumption (stand-by) modes

Sleep mode (CPU operating clock stops, peripherals continue to operate.)

Pseudo-clock mode (Only oscillation clock and timebase timer continue to operate.)

Clock mode (Main oscillation clock stops, sub-clock and clock timer continue to operate.)

Stop mode (Main oscillation and sub-clock both stop.)

CPU intermittent operation mode

Hardware stand-by mode (Change to stop mpde by operating hardware stand-by pins.)
