STK14C88-5C35M

The Infineon STK14C88-5C35M is a 256 Kbit (32K × 8) non-volatile static random-access memory (nvSRAM) with AutoStore, manufactured in a hermetic ceramic dual-in-line package (CDIP) and rated for the full military temperature range. This device integrates the fast 35 ns asynchronous SRAM interface with a matching non-volatile quantum-trap storage array, delivering unlimited write endurance in the SRAM cells while automatically transferring the entire memory content to the non-volatile elements if supply voltage drops below a safe threshold. On power-up the data is recalled without external intervention, effectively eliminating the need for battery-backed SRAM solutions. The CDIP package provides robust environmental protection, making the part suited for circuits where shock, vibration, moisture, and extreme temperatures are design constraints.

Typical end-use scenarios span defense, aerospace, and high-reliability industrial systems that must preserve critical state information during unexpected power loss. The part is commonly deployed in flight computers, mission recorders, radar processing boards, secure communications platforms, and industrial safety controllers where continuous data integrity is non-negotiable. Procurement professionals should recognize that this is a military-temperature-grade component (–55 °C to +125 °C) with a niche nvSRAM architecture; long-term supply can be subject to obsolescence management cycles and extended lead times common to ceramic-packaged, high-reliability semiconductor lines. Sourcing through authorized channels ensures traceability, latest revision control, and conformance to the manufacturer’s performance specifications for this legacy Simtek-origin product now under Infineon heritage.
