IC SONY CXK5864P-15L - DIP-28

The Sony CXK5864P-15L is a 64-kilobit (8K × 8-bit) static RAM (SRAM) integrated circuit produced by Sony.

It is built with CMOS technology and is designed for fast, low-power operation in a standard 28-pin Dual In-Line Package (DIP-28).

Key Specifications

Memory Capacity: 8,192 words × 8 bits (64K bits total)

Access Time: 150 ns

Operating Voltage: 5V

Package Type: 28-pin Plastic DIP (PDIP)

Technology: CMOS

Common Uses

The CXK5864P-15L is primarily used in retro computing, vintage audio equipment, and older electronic circuit designs that require non-volatile or battery-backed static RAM to store system parameters, firmware, or temporary data.

Because it operates on a standard 5V rail and uses an industry-standard pinout, it is often a drop-in replacement for equivalent chips from other manufacturers like the HM6264.
