Product overview
The UT8Q512K32E is a 16 Mb radiation-tolerant CMOS static RAM with 25 ns maximum address access at a 3.3 V supply. It contains four 512K × 8 memories with a common output enable; separate die controls support 8-, 16-, 24- or 32-bit accesses. TTL-compatible input and output levels and a three-state bidirectional bus support connection to the host memory interface. The device uses a 68-lead dual-cavity ceramic quad flatpack, with quality and radiation-assurance options defined by its SMD ordering code. Select the appropriate voltage, package and temperature configuration for the design, and use the radiation-assured ordering option when the application requires guaranteed total-dose performance.

More about this product
Product features
- Asynchronous memory interface
- TTL-compatible input and output levels
- Three-state bidirectional data bus
- Flexible 8-, 16-, 24- or 32-bit accesses
Control the memory bus
Active-low chip enable, write enable and output enable control data access. Three-state output drivers isolate the device when deselected or writing.
Flexible access width
The four 8-bit memory die can be grouped through their chip-enable and write-enable controls for 8-, 16-, 24- or 32-bit accesses.
Applications
- Fault-tolerant designs for low Earth orbit
