µPD77018A, 77019 are 16 bits fixed-point DSPs (Digital Signal Processors) developed for digital signal processing

with its demand for high speed and precision.

Maximum operating speed of the

µPD77018A, 77019 is improved compared with the µPD77015, 77017, 77018.

And the

µPD77019 internal instruction RAM (4K × 32 bits) is suitable for program code replacement.

FEATURES

• FUNCTIONS

• Instruction cycle: 16.6 ns (MIN.)

Operation clock: 60 MHz

External clock: 60, 30, 20, 15, 7.5 MHz

Crystal: 60 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)
