12 ns asynchronous SRAM for fast cache or buffer duty
The Infineon CY7C10212CV33-12BAXET is a 1Mbit asynchronous SRAM organized as 64K x 16 bits, with a 12 ns access time that lets it keep up with moderate-speed processors and DSPs without inserting wait states.
48-FBGA footprint — plan for fine-pitch assembly
The part comes in a 48-ball TFBGA (7x7 mm) package.
Active status — no LTB clock ticking
Infineon lists the CY7C10212CV33-12BAXET as Active. That means no announced end-of-life, no last-time-buy deadline, and the part remains in the factory price book.
Parallel interface — simple bus integration
The memory interface is parallel asynchronous — no clock, no burst mode, no DLL to lock. Address and data are latched on the falling edge of chip enable or write enable, whichever comes last.
That margin absorbs the drop from a switching regulator's ripple or a long PCB trace without needing a local LDO. The 3V floor also means the SRAM stays alive during a brown-out condition down to 3.0V — useful if the system has a backup battery or a hold-up capacitor on the 3.3V rail.
