µPD77015, 77017, 77018 are 16 bits fixed-point DSPs (Digital Signal Processors) developed for digital signal

processing with its demand for high speed and precision.

FEATURES

• FUNCTIONS

• Instruction cycle: 30 ns (MIN.)

Operation clock: 33 MHz

External clock: 33, 16.5, 8.25, 4.125 MHz

Crystal: 33 MHz

• On-chip PLL to provide higher operation clock than the external clock

• Dual load/store

• Hardware loop function

• Conditional execution

• Executes product-sum operation in one instruction cycle

• PROGRAMMING

• 16 bits

× 16 bits + 40 bits → 40 bits multiply accumulator

• 8 general registers (40 bits each)

• 8 ROM/RAM data pointer: each data memory area has 4 registers

• 10 source interrupts (external: 4, internal: 6)

• 3 operand instructions (example: R0 = R0 +R1L

∗R2L)

• Nonpipeline on execution stage

• MEMORY AREAS

• Instruction memory area : 64K words

× 32 bits

• Data memory areas : 64K words

× 16 bits × 2 (X memory, Y memory)

• CLOCK GENERATOR

• Mask option for CLKOUT pin:

Fixed to the low level.

Does not output the internal system clock.

• Selectable source clock: external clock input and crystal resonator

[External clock]

On-chip PLL to provide higher operation clock (33 MHz MAX.) than the external clock.

Variable multiple rates (1, 2, 4, 8) by mask option.

[Crystal resonator]

Oscillation frequency corresponds directly to the system clock frequency (Sure to specify the mask option

frequency multiple as "1").
