■ DESCRIPTION

The MB90560/565 series is a general-purpose 16-bit microcontroller designed for industrial, OA, and process control applications that require high-speed real-time processing. The device features a multi-function timer able to output a programmable waveform.

The microcontroller instruction set is based on the same AT architecture as the F2MC-8L and F2MC-16L families with additional instructions for high-level languages, extended addressing modes, enhanced signed 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 oscillator circuit and PLL clock multiplication circuit

• Oscillation clock

Clock speed selectable from either the machine clock, main clock, or PLL clock. The main clock is the oscillation

clock divided into 2 (0.5 MHz to 8 MHz for a 1 MHz to 16 MHz base oscillation) . The PLL clock is the oscillation

clock multiplied by one to four (4 MHz to 16 MHz for a 4 MHz base oscillation) .

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

• Maximum CPU memory space : 16 MB

• 24-bit addressing

• Bank addressing

• Instruction set

• Bit, byte, word, and long word data types

• 23 different addressing modes

• Enhanced calculation precision using a 32-bit accumulator

• Enhanced signed multiplication and division instructions and RETI instruction

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

• Uses a system stack pointer

• Symmetric instruction set and barrel shift instructions

• Program patch function (2 address pointers) .

• 4-byte instruction queue

• Interrupt function

• Priority levels are programmable

• 32 interrupts

• Data transfer function

• Extended intelligent I/O service function : Up to 16 channels

• Low-power consumption modes

• Sleep mode (CPU operating clock stops.)

• Timebase timer mode (Only oscillation clock and timebase timer continue to operate.)

• Stop mode (Oscillation clock stops.)

• CPU intermittent operation mode (The CPU operates intermittently at the specified interval.)

• Package

• LQFP-64P (FTP-64P-M09 : 0.65 mm pin pitch)

• QFP-64P (FTP-64P-M06 : 1.00 mm pin pitch)

• SH-DIP (DIP-64P-M01 : 1.778 mm pin pitch)

• Process : CMOS technology

■ PERIPHERAL FUNCTIONS (RESOURCES)

• I/O ports : 51 ports (max.)

• Timebase timer : 1 channel

• Watchdog timer : 1 channel

• 16-bit reload timer : 2 channel 5

• Multi-function timer

• 16-bit free-run timer : 1 channel

• Output compare : 6 channels

Can output an interrupt request when a match occurs between the count in the 16-bit freerun timer and the value set in the compare register.

• Input capture : 4 channels

On detecting an active edge on the input signal from an external input pin, copies the count value of the 16- bit freerun timer to the input capture data register and generates an interrupt request.

• 8/16-bit PPG timer (8-bit × 6 channels or 16-bit × 3 channels) The period and duty of the output pulse can be set by the program.

• Waveform generator (8-bit timer : 3 channels)

• UART : 2 channels

• Full-duplex, double-buffered (8-bit)

• Can be set to asynchronous or clock synchronous serial transfer (I/O expansion serial) operation

• DTP/external interrupt circuit (8 channels)

• External interrupts can activate the extended intelligent I/O service.

• Generates interrupts in response to external interrupt inputs.

• Delayed interrupt generation module

• Generates an interrupt request for task switching.

• 8/10-bit A/D converter : 8 channels

• 8-bit or 10-bit resolution selectable
