description
The SMJ320C50KGD digital signal processor (DSP) is a high-performance, 16-bit, fixed-point processor
manufactured in 0.64-µm double-level metal CMOS technology.
The SMJ320C50 KGD employs the hot-chuck-probe process. This process uses standard probed product that
is tested again, this time at full data sheet specifications, in wafer form at speed and elevated temperature
(125°C). Each individual die is then sawed, inspected, and packaged for shipment.
A number of enhancements to the basic ’C2x architecture give the ’C50 a minimum 2x performance over the
previous generation. A four-deep instruction pipeline, which incorporates delayed branching, delayed call to a
subroutine, and delayed return from a subroutine, allows the ’C50 to perform instructions in fewer cycles. The
addition of a PLU gives the ’C50 a method of manipulating bits in data memory without using the ACC and the
ALU. The ’C50 has additional shifting and scaling capabilities for proper alignment of multiplicands or for storage
of values to data memory.
With the addition of the IDLE2 instruction, the ’C50 achieves low-power consumption. IDLE2 removes the
functional clock from the internal hardware of the ’C50 that puts it into a total-sleep mode using only 5 µA. A
low-logic level on an external interrupt with a chip duration of at least five clock cycles ends the IDLE2 mode.
