CDP1822C/3  
High-Reliability CMOS  
256-Word x 4-Bit LSI Static RAM  
March 1997  
Features  
Description  
• For Applications in Aerospace, Military, and Critical  
Industrial Equipment  
The CDP1822C/3 is a 256 word by 4-bit random access  
memory designed for use in memory systems where high  
speed, low operating current, and simplicity in use are  
desirable. The CDP1822 features high speed and excellent  
noise immunity. It has separate data inputs and outputs and  
utilizes a single power supply of 4V to 6.5V.  
• Interfaces Directly with CDP1802 Microprocessor  
• Very Low Operating Current  
- At V  
= 5V and Cycle Time = 1µs . . . . . . 4mA (Typ)  
DD  
Two Chip Select inputs simplify system expansion. An output  
Disable control provides Wire-OR-capability and is also  
useful in common Input/Output systems. The Output Disable  
input allows this RAM to be used in common data Input/Out-  
put systems by forcing the output into a high impedance  
state during a write operation independent of the Chip Select  
input condition. The output assumes a high impedance state  
when the Output Disable is at high level or when the chip is  
deselected by CS1 and/or CS2.  
• Static CMOS Silicon-On-Sapphire Circuitry  
- CD4000 Series Compatible  
• Industry Standard Pinout  
• Two Chip Select Inputs - Simple Memory Expansion  
• Memory Retention for Standby. . . . . . . . . . . . . 2V (Min)  
Battery Voltage  
• Single Power Supply Operation . . . . . . . . . . 4V to 6.5V  
The high noise immunity of the CMOS technology is  
preserved in this design. For TTL interfacing at 5V operation,  
excellent system noise margin is preserved by using an  
external pull-up resistor at each input.  
• High Noise Immunity 30% of V . . . . . . . . . 4V to 6.5V

• Output Disable for Common I/O Systems  
• Three-State Data Output for Bus Oriented Systems  
• Separate Data Inputs and Outputs  
• Latch-Up-Free Transient Radiation Tolerance
