Features

Description

• Industry Standard Pinout

The MWS5101 and MWS5101A are 256 word by 4-bit static

random access memories designed for use in memory

systems where high speed, very low operating current, and

simplicity in use are desirable. They have separate data

inputs and outputs and utilize a single power supply of 4V to

6.5V. The MWS5101 and MWS5101A differ in input voltage

characteristics (MWS5101A is TTL compatible).

• Very Low Operating Current . . . . . . . . . . . . . . . . . . 8mA

at V

= 5V and Cycle Time = 1µs

• Two Chip Select Inputs Simple Memory Expansion

• Memory Retention for Standby. . . . . . . . . . . . . 2V (Min)

Battery Voltage

Two Chip Select inputs are provided to simplify system

expansion. An Output Disable control provides Wire-OR

capability and is also useful in common Input/Output

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.

• Output Disable for Common I/O Systems

• Three-State Data Output for Bus Oriented Systems

• Separate Data Inputs and Outputs

• TTL Compatible (MWS5101A)

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.

For applications requiring wider temperature and operating

voltage ranges, the mechanically and functionally equivalent

static RAM, CDP1822 may be used.

The MWS5101 and MWS5101A types are supplied in 22

lead hermetic dual-in-line, sidebrazed ceramic packages (D

sufﬁx), in 22 lead dual-in-line plastic packages (E sufﬁx), and

in chip form (H sufﬁx).
