Part identity and key parametrics
The Infineon CY62128DV30LL-55ZAXI is a 1 Mbit parallel SRAM from the MoBL series, organized as 128K x 8 bits. Access time is 55 ns, with a matching 55 ns write cycle time — this sets the bus timing floor for the memory controller. Supply voltage is 2.2 V, and the operating temperature range spans -40°C to 85°C, covering industrial-grade environments.
Board-fit and interface note
Surface-mount 32TSOP package — the 0.50 mm pitch and 8 mm body width require a standard SMT reflow profile; store the reels dry per MSL level. Parallel interface means it connects directly to an address/data bus — no serial translation needed, but the pin count (32) occupies more board area than a serial flash of the same density.
