CY7C346-35RMB

CY7C346-35RMB is a Cypress 128-macrocell MAX erasable programmable logic device (EPLD). The Cypress datasheet divides the 128 macrocells into eight logic array blocks, with 20 dedicated inputs, up to 64 bidirectional I/O pins and 256 shared expander product terms. The CY7C346 uses 0.8 µm double-metal CMOS EPROM technology. For the exact -35RMB ordering code, the ordering table specifies a 35 ns speed grade and the R100 100-pin windowed ceramic pin grid array in the military operating range.

The military range is -55°C to +125°C case temperature with a 5 V ±10% supply. ZZX Electronics lists 190 pcs with date code 1844. Because this is a UV-erasable legacy programmable device, procurement should verify programmed versus erased state, window condition, original marking, lot/date-code evidence, handling history and the required screening flow instead of inferring qualification from the ceramic package alone.
