The Infineon CY62136VLL-55ZI is a 2 Mbit asynchronous SRAM from the MoBL® (More Battery Life) series, organized as 128K words by 16 bits. It is a volatile, parallel-interface memory designed for low-power data buffering in embedded systems — think industrial controllers, telecom line cards, medical instrumentation, and portable instruments where a 3.3 V rail is already on the board. The 55 ns access time puts it in the mid-speed tier for asynchronous SRAM, fast enough to keep up with a 16-bit microcontroller or DSP without wait states at moderate clock rates.
No 5 V tolerance on the I/O — keep the supply inside the 3.6 V ceiling.
Package and mounting
Housed in a 44-pin TSOP II (0.400" body width, 10.16 mm), this is a gull-wing leaded package that reworks cleanly with a hot-air station — no hidden pads, no underfill. The 0.8 mm pitch is forgiving for hand rework; just preheat the board to 100°C to avoid lifting the inner-layer traces on a multi-layer PCB. Bulk shipping means the parts arrive in a tube or tray, not taped, so handle them with ESD tweezers.
