The parallel interface is 18-bit wide, so the PCB trace matching across the data bus matters for timing closure at this speed. ## 165-ball FBGA — rework and layout notes Housed in a 165-ball FBGA measuring 13x15 mm. Fine-pitch BGA — expect 1 mm ball pitch, which is manageable with standard PCB fab processes (4-mil trace/space). Route the 18 data lines plus address and control on inner layers; use microvia or through-via escape depending on layer count. Hot-air rework is possible with a bottom-side preheat profile; a stencil aperture reduction to 80–85% of the pad diameter helps prevent solder bridging. This rules out outdoor telecom cabinets, automotive under-hood, or factory floor without HVAC.","metaTitle":"Cypress CY7C1423KV18-250BZC 36Mbit DDR II SRAM, 250 MHz","metaDescription":"Cypress CY7C1423KV18-250BZC 36Mbit (2M x 18) synchronous DDR II SRAM, 250 MHz clock, parallel interface, 1.7–1.9V supply, 165-FBGA.
