The parallel interface means no clock is needed — the bus controller simply asserts address and reads or writes within the 45 ns window, making it a straightforward drop-in for 8-bit microcontrollers or legacy memory maps. ## Industrial temperature and board-fit The 32-TSOP I package (0.724\" body width, 18.40 mm) uses a standard 0.50 mm pitch footprint — the same as many 8-pin SOIC and TSOP-II memories, so the PCB layout reuses existing land patterns. Supply decoupling should follow the datasheet recommendation: a 0.1 µF ceramic within 3 mm of each VDD pin, with a 4.7 µF bulk cap near the package. ## Speed-grade decision: 45 ns vs faster peers The closest parametric peer in the same 128K x 8 organization and TSOP I footprint is the CY7C109D-10ZXIT, which offers a 10 ns access time. The 45 ns part here is the cost-optimized, lower-power option — it draws less standby current and costs less per unit, but the bus controller must tolerate the longer access window. If the system clock runs above 20 MHz or the memory is shared with a DMA engine, the 10 ns part is the safer choice. For a 8-bit MCU running at 8-16 MHz with wait states, the 45 ns part fits without timing issues.","metaTitle":"Infineon CY62128EV30LL-45ZXIT SRAM, 1Mbit, 45ns, 2.2-3.6V","metaDescription":"Infineon MoBL® CY62128EV30LL-45ZXIT async SRAM, 1Mbit (128K x 8), 45 ns access, 2.2-3.6V, -40 to 85°C, 32-TSOP I.

The key difference is access time: 10 ns vs 45 ns. The CY7C109D is faster but draws higher active current. For a drop-in replacement without rewiring, verify the bus timing margin; the 10 ns part will work in any socket that accepts 45 ns, but the 45 ns part may not meet timing in a system designed for 10 ns."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY62128EV30LL-45ZXIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY62128EV30LL-45ZXIT when reusing this data.
