LC4064ZE-7TN100C

LC4064ZE-7TN100C is a CMOS SRAM memory device in the 4064 family. It provides 64 Kibits of storage organized as 8K x 8. It’s an asynchronous, single-port SRAM with 13 address inputs (A0–A12), 8 bidirectional data I/O lines (DQ0–DQ7), and three control inputs: chip select/CE, output enable (OE), and write enable (WE). When CE is active, data can be read with OE asserted and WE deasserted, or written by asserting WE during a valid address and data setup; outputs are three-state when not enabled. Typical supply is around 5V (check the specific variant) and speed grade -7 indicates faster access in that family; exact timing and temperature range depend on the vendor and packaging. The TN100C suffix usually relates to packaging (e.g., tape-and-reel), while LC and ZE denote the vendor family and temperature range. Commonly used for memory expansion in microcontrollers, buffering, caches, and video RAM. For precise pinout, voltages, timing, and availability, refer to the exact datasheet from the vendor.
