The 4.5V to 5.5V supply rail matches legacy 5 V logic families — no level translation needed when connecting to 5 V CPLDs or older microcontrollers. The 15 ns write cycle time (word, page) matches the read access, so back-to-back read-write operations run at the same bus speed without wait states. This is a volatile memory — data is lost at power-down; typical use is as a fast scratchpad, cache buffer, or configuration store in embedded systems. Infineon has discontinued production; no future manufacturing is planned. Sourcing is limited to inventory already in the channel — broker-held stock, surplus lots, or authorized overstock with remaining shelf life. When sourcing from open market, verify date code and moisture sensitivity level (MSL) against the original Cypress/Infineon datasheet — older trays may have been stored outside recommended conditions. ## Commercial temperature grade — indoor use only If the BOM requires a wider temperature grade, a different SRAM in the same package but with industrial or automotive qualification would be needed — expect a different base product number and likely a different supply voltage range.","metaTitle":"CY7C109BN-15ZXC SRAM 1Mbit 15 ns TSOP I Infineon Obsolete","metaDescription":"CY7C109BN-15ZXC Infineon 1Mbit (128K x 8) asynchronous SRAM, 15 ns access, 4.5V-5.5V, 32-TSOP I, 0°C-70°C.

We source it through independent distribution — broker inventory, surplus stock, or authorized overstock. Submit an RFQ with your target quantity and acceptable date code window; we will confirm availability, pricing, and delivery terms at quote time. No stock-holding claim is made here; each order is sourced per request."},{"question":"What is the memory organization and voltage supply for CY7C109BN-15ZXC?","answer":"Memory organization is 128K x 8 (1 Mbit total).
