• Manufacturer Part Number: z893232yfsc
• Description: 16-bit Digital Signal Processors
• Manufacturer: ZiLOG Semiconductor

GENERAL DESCRIPTION (Continued)
The Z893X3 DSP family is 100 percent source and object-
code compatible with the existing Z89321/371/391 devices,
providing users, who can benefit from increased integration
and reduced system cost, an easy migration path from one
DSP product to the next.
Throughout this specification, references to the Z89323
device applies equally to the Z89373 and Z89393, unless
otherwise specified.
