The Microchip Technology WS128K32-85G4TIA is a standard asynchronous SRAM component from the WS128K32 series. This device offers a memory density of 4Mb, organized as 128K words by 32 bits, with a maximum access time of 85ns. It operates using CMOS technology and features a common I/O type with 3-state outputs, controlled by an output enable signal. The component is configurable as 512K x 8, providing flexibility in memory mapping.
Designed for surface mounting, the WS128K32-85G4TIA is housed in a 68-terminal ceramic, metal-sealed cofired CQFP package (JESD-30 Code S-CQFP-F68) with a terminal pitch of 1.27mm. It operates within a temperature range of -40°C to +85°C and supports a supply voltage from 4.5V to 5.5V, with a nominal voltage of 5V. Typical applications for this component include industrial control systems, medical equipment, and aerospace and defense systems where high reliability and performance are critical. The standby current is rated at a maximum of 20mA.
