描述 Description

16 bits, Fixed-point Digital Signal ProcessorThe µPD77019-013 is a masked 16 bits fixed-point DSP (Digital Signal Processor) developed for digital signal processing with its demand for high speed and precision.
The µPD77019-013 internal ROM area is masked already by the void code to use as RAM based DSP without mask code ordering process. Also the µPD77019-013 can operate as simplified evaluate chip for as the µPD7701x family.
About mask ROM and mask option, there are following differences between the µPD77019-013 and µPD77019.FEATURES
• FUNCTIONS
• Instruction cycle: 16.6 ns (MIN.)
  Operation clock: 60 MHz
  External clock: 15 MHz
• 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
• On-chip PLL to provide higher operation clock (60 MHz max.) than the external clock. PLL clock multiple rate is fixed to 4.
• ON-CHIP PERIPHERAL
• I/O port: 4 bits
• Serial I/O (16 bits): 2 channels
• Host I/O (8 bits): 1 channel
• CMOS
• +3 V single power supply
