Product overview

The UT8ER512K32 is a 16 Mb monolithic CMOS SRAM organized as 512K × 32, with embedded error detection and correction. It offers 20 ns read and 10 ns write access and uses separate 3.3 V I/O and 1.8 V core supplies. Programmable master and slave scrub modes let the system balance error correction against memory availability. Single-bit errors are corrected on read output, while periodic scrubbing rewrites corrected data into the memory array. Active-low and active-high enables, output enable and three-state drivers support bus control. The device is supplied in a 68-lead ceramic quad flatpack, with SMD-defined quality and radiation-assurance options.

Product features

  • Embedded EDAC with programmable scrub timing
  • Master and slave device options
  • Asynchronous SRAM-compatible interface
  • Deselected power-down mode

Read correction and array scrubbing

Read cycles correct single-bit errors on the output bus without rewriting the core array. Periodic scrub cycles perform the array correction, limiting accumulation of memory upsets.

Programmable scrub scheduling

A master device scrubs at the programmed period. A slave device scrubs when SCRUB is asserted, allowing system-controlled scheduling.
