Dual-port SRAM with multiple supply rails
The Infineon CYDMX128A16-65BVXIKB is a 128Kbit dual-port asynchronous SRAM organised as 8K x 16 bits, with a 65 ns access time across the full operating range. It accepts three separate supply voltage bands — 1.7V–1.9V, 2.4V–2.6V, and 2.7V–3.3V — allowing the core and I/O to run at different levels without an external level shifter on the address and data bus.
Board-fit and temperature grade
Housed in a 100-ball VFBGA (6x6 mm body), the package footprint suits dense PCB layouts where board space is at a premium — the fine-pitch BGA demands careful fan-out via microvias on a multi-layer board.
Active production and sourcing posture
Sourced through independent distribution channels, each unit is verified for date-code consistency and marking integrity before shipment — the laser etch is a fingerprint, and we check it traces cleanly to Infineon's plant records.
Parallel interface and write timing
The memory interface is parallel, with a write cycle time matching the 65 ns access — word and page writes complete in the same cycle, simplifying the timing budget in a synchronous system.
