scope:

This drawing documents two product assurance classes, high reliability (device class H) and space application (device class K) and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). When available. a choice of radiation hardness assurance levels are reflected in the PIN.

The PIN shall be as shown in the following example:

Device classes H and K RHA marked devices shall meet the MIL-PRF-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.

The device type(s) shall identify the circuit function as follows:

Device type Generic number Circuit function Access time 01 WS512K32F-120G4Q SRAM, 512K × 32-bit 120 ns 02 WS512K32F-100G4Q SRAM, 512K × 32-bit 100 ns 03 WS512K32F-85G4Q SRAM, 512K × 32-bit 85 ns 04 WS512K32F-70G4Q SRAM, 512K × 32-bit 70 ns 05 WS512K32F-55G4Q SRAM, 512K × 32-bit 55 ns 06 WS512K32F-45G4Q SRAM, 512K × 32-bit 45 ns 07 WS512K32F-35G4Q SRAM, 512K × 32-bit 35 ns 08 WS512K32F-25G4Q SRAM, 512K × 32-bit 25 ns 09 WS512K32F-20G4Q SRAM, 512K × 32-bit 20 ns 10 WS512K32M-45G4Q SRAM, 512K × 32-bit 45 ns 11 WS512K32M-35G4Q SRAM. 512K × 32-bit 35 ns 12 WS512K32M-25G4Q SRAM, 512K × 32-bit 25 ns

This device class designator shall be a single letter identifying the product assurance lever as follows:
