4096-Word X a-Bit Static Read-Only Memory
Features: Interfaces with CDP1800-series microprocessors
(fCIOCk :s 5 MHz) without addItIonal components
On-chip address latch On-chip address decoder provides programmable location within 64K
memory space Three-state outputs
The RCA-CDP1837C is a 32768-bit mask-programmable
CMOS read-only memory, organized as 4096 words x 8 bits and is completely static: no clocks required. It will directly interface with CDP1800-series microprocessors, having clock frequencies up to 5 MHz, without additional components.
The CDP1837C responds to a 16-bit address multiplexed on 8 address lines Address latches are provided on chip for storing the high byte address data. By mask opti...
