M68Z128W General Description
The M68Z128W is a 1 Mbit (1,048,576 bit) Fast CMOS SRAM, organized as 131,072 words by 8 bits. The device features fully static operation requiring no external clocks or timing strobes, with equal address access and cycle times. It requires a single 3.0V (+0.6V / 0.3V) supply, and all inputs and outputs are TTL compatible. This device has an automatic power-down feature, reducing the power consumption by over 99% when deselected. The M68Z128W is available in the standard 450mil-wide TSOP type 1 package.
M68Z128W Maximum Ratings
| Symbol | Parameter | Value | Unit |
| TA | Ambient Operating Temperature | 0 to 70 | °C |
| TSTG | Storage Temperature | 65 to 150 | °C |
| VIO (2) | Input or Output Voltage | 0.3 to VCC + 0.3 | °C |
| VCC | Supply Voltage | 0.3 to 7.0 | V |
| IO (3) | Output Current | 20 | V |
| PD | Power Dissipation | 1 | V |
Note: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.
2. Up to a maximum operating VCC of 5.5V only.
3. One output at a time, not to exceed 1 second duration.
