Harris Semiconductor M1-6616-9 Static RAM (SRAM) chip gomd pins

Key Features

​Manufacturer: Harris Semiconductor (now part of L3Harris Technologies) 🏢

​Part Number: M1-6616-9. The "M1" prefix indicates it was a product line identifier for military-grade or high-reliability components, while "6616" specifies the chip's function and organization.

​Function: It is a Static RAM (SRAM) chip. Unlike Dynamic RAM (DRAM), SRAM does not need to be refreshed periodically to retain data, making it faster and more expensive.

​Memory Configuration: It has a memory capacity of 2K x 8 bits, which is 2048 words, each 8 bits (one byte) wide, for a total of 16,384 bits (or 2KB) of memory.

​Technology: It's a CMOS (Complementary Metal-Oxide-Semiconductor) chip, a technology known for its low power consumption.

​Date Code: The "8609" on the chip is a date code, indicating it was manufactured in the 9th week of 1986. This dates the component to the early days of personal computing and dedicated electronics.

​Package: The chip is in a DIP (Dual In-line Package). The gold top is a common feature of hermetic, ceramic packages used for high-reliability components, often for military or aerospace applications.
