Product overview
The UT8CR512K32 is a 16 Mb asynchronous CMOS SRAM multichip module containing four 512K × 8 memories. Individual chip-enable and write-enable controls allow 8-, 16-, 24- or 32-bit accesses, while a common output enable and three-state drivers support shared-bus operation. The module provides 17 ns maximum access time with separate 3.3 V I/O and 1.8 V core supplies. A power-down feature reduces consumption by more than 90% when deselected. Its 68-lead ceramic quad flatpack and SMD ordering options support selection of temperature and radiation assurance for the system, without requiring a different interface for each supported access width.

More about this product
Product features
- Four 512K × eight SRAM die in one module
- Flexible 8-, 16-, 24- or 32-bit accesses
- Three-state bidirectional bus
- Power-down mode when deselected
Flexible bus width
Separate die enables and write enables allow the four 8-bit memories to be combined for 8-, 16-, 24- or 32-bit accesses using a common output enable.
