512-Word X a-Bit Static
Read-Only Memory
Features:
• Compatible with CDP1800 and CD4000-series
devices
• Functional replacement for industry type 2704
512 x 8 EPROM
• Three-state outputs
The RCA COP1832 and COP1832C types are 4096-bit
mask-programmable CMOS read-only memories organized
as 512 words x 8 bits and designed for use in COP1800-
series microprocessor systems.
The COP1832 ROMs are completely static; no clocks are
required.
A Chip-Select input (CS) is provided for memory expansion.
Outputs are enabled when CS=O.
The CDP1832 is a pin-for-pin compatible replacement for
the industry types 2704 EPROM.
The COP1832C is functionally identical to the COP1832.
The COP1832 has an operating voltage range of 4 to 10.5
volts, and the COP1832C has an operating voltage range of
4 to 6.5 volts.
The COP1832 and COP1832C are supplied in 24-lead,
hermetic, dual-in-line, side-brazed, ceramic packages (0
suffix) and in 24-lead dual-in-line plastic packages (E
suffix). The COP1832C is also available in chip form (H
suffix).
