Product overview

The UT9Q512E is a 4 Mb radiation-tolerant CMOS static RAM with 20 ns maximum address access at a 5 V supply. Its 512K × 8 organization, active-low chip enable and active-low output enable provide conventional asynchronous memory control. TTL-compatible input and output levels and a three-state bidirectional bus support connection to the host memory interface. The device uses a 36-lead ceramic 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.
