Product details

45 ns byte-wide SRAM for 8-bit buses

The CY62128EV30LL-45SXI: For an 8-bit MCU or a FIFO buffer running at typical bus speeds, 45 ns sets the read-cycle ceiling — the processor must stretch its wait states if it clocks faster than ~22 MHz on consecutive reads. The industrial temperature grade (-40 to +85 °C) covers factory-floor, outdoor telecom cabinet, and unheated enclosure deployments.

Housed in a 32-SOIC (0.445-inch body width, 11.30 mm), the same footprint used by legacy 128K x 8 SRAMs from multiple vendors. Supplied in tube. The write cycle time matches the read access at 45 ns — byte-wide writes complete in one cycle with no page-mode or burst overhead.

ROHS3 compliant, with no exemption-based restrictions that would block EU or California market entry. The part belongs to the MoBL (Motherboard Battery-Less) series — Infineon's low-power asynchronous SRAM family characterized by reduced standby current.

Frequently asked questions

What is the closest pin-compatible alternative to CY62128EV30LL-45SXI?

The 32-SOIC (300-mil) footprint is a standard JEDEC outline used by multiple vendors for 128K x 8 asynchronous SRAMs — functionally equivalent parts exist from ISSI, Alliance Memory, and others, but each must be verified for access time, supply range, and temperature grade against the BOM requirements.

What compliance documentation does Infineon provide for CY62128EV30LL-45SXI?

Infineon certifies the CY62128EV30LL-45SXI as ROHS3 Compliant. Standard Infineon compliance documents (material declaration, REACH SVHC declaration) are typically available through the manufacturer's product page or by request at RFQ.
