The STK11C88-3N35I is a 32Kx8 non-volatile SRAM from the * series, combining the fast read/write of SRAM with on-chip non-volatile storage. The 35 ns access time lets it interface with mid-speed microcontrollers and DSPs without inserting wait states — a direct fit for processor buses running up to about 28 MHz. Typical applications include configuration storage, calibration data, and parameter logging where the system needs to retain state through power loss without a battery.
Access time — what the 35 ns means for bus margin
On a 20 MHz bus with a 50 ns cycle, this leaves 15 ns of margin for address decoding, buffer delay, and signal settling — comfortable for a single glue-logic stage. If the host runs at 33 MHz (30 ns cycle), the margin shrinks to zero, and the designer needs to check whether the part's output-enable timing can still meet setup. The 35 ns figure is the ceiling; a faster 25 ns sibling would be the pick for a 33 MHz bus.
Lifecycle — active, no LTB pressure
Product status is Active per the manufacturer's listing. For the BOM buyer, this means the part can still be specified into new production runs without an obsolescence clock ticking.
Bulk packaging — tray or tube delivery
If your pick-and-place line expects reels, you will need to hand-place or transfer to a carrier tape.
