DATA SHEET
MOS INTEGRATED CIRCUIT
µPD77018A, 77019
16 bits, Fixed-point Digital Signal Processor
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 +R1LR2L)
• 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)
In this document, all descriptions of the µPD77018A also apply to the µPD77019, unless otherwise
specified.
The information in this document is subject to change without notice.
