6585F

The 6585F is a type of integrated circuit (IC) commonly used in digital electronics, specifically as a 64-kilobit (8 kilobyte) static random-access memory (SRAM) chip. Introduced by Texas Instruments, it is part of the TMS4000 series and was widely adopted in the 1980s and early 1990s for applications requiring fast, volatile memory storage.

The 6585F operates at a supply voltage of 5 volts and provides 8-bit data buses, making it suitable for systems requiring parallel data transfer. It features asynchronous operation, allowing for flexible timing with external circuitry, and includes a chip enable (CE) and output enable (OE) pin for control. The chip is organized as 8,192 words by 8 bits, offering a total of 65,536 bits of memory.

Due to its static nature, the 6585F does not require periodic refreshing, unlike dynamic RAM (DRAM) chips, which simplifies its use in many applications. It was commonly used in early personal computers, embedded systems, and other digital devices where low-power, high-speed memory was required. Over time, it has been largely superseded by modern SRAM and DRAM technologies, but it remains a notable component in the history of semiconductor memory.

The 6585F is housed in a 28-pin dual inline package (DIP) or small outline integrated circuit (SOIC) form factor, making it compatible with standard circuit board designs. Its reliability and performance during its era contributed to its enduring presence in vintage computing and retro technology projects.
