Description

The CDP1824/3 and CDP1824C/3 types are high-reliability
CMOS 32-word x 8-bit fully static random-access memories
for use in CDP1800-series microprocessor systems. These
parts are compatible with the CDP1802 microprocessor and
will interface directly without additional components.

The CDP1824/3 is fully decoded and does not require a pre­charge or clocking signal for proper operation. It has com­mon input and output and is operated from a single voltage
supply. The
three-state output drivers, and overrides the
CS input is provided for memory expansion.

The CDP1824C/3 is functionally identical to the CDP1824/3.
The CDP1824/3 has a recommended operating voltage
range of 4V to 10.5V, and the CDP1824C/3 has an operating
voltage range of 4V to 6.5V.

NOTES:

1. The CDP1824C/3 meets all 5V Static Electrical Characteristics of the CDP1824/3 except Quiescent Device Current for which the limits
are IDD = 200µA at +25oC/-55oC; IDD = 1000µA at +125oC.

2. Guaranteed, but not tested.
