DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD77015,77017,77018  
16 bits, Fixed-point Digital Signal Processor  
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").  
In this document, all descriptions of the µPD77017 also apply to the µPD77015 and µPD77018, unless  
otherwise specified.  
The information in this document is subject to change without notice.
