Key Features
Cascadable up to 4 units for 32-bit by 32-bit multiply or64 -7- 32 bit divide.
8-blt by 8-bit multiply or 16 -7- 18 bit divide in 5.6 jJs at 5 Vor 2.8 jJs at 10 V.
Direct interface to CDP1800 series microprocessors.
Easy interface to other 8-bit microprocessors.
Significantly increases throughput of microprocessor used for
arithmetic calculations
The RCA-CDP1855 and CDP1855C are CMOS 8-bit multiply/divide units which can be used to greatly increase.
