The 70V658S12BC is a high-speed, asynchronous dual-port static RAM from Quarktwin Technology Ltd., featuring a memory configuration of 128/64/32K x 36 bits. It operates at a voltage of 3.3V (¬±150mV) for the core and offers selectable I/O voltage levels of 3.3V (¬±150mV) or 2.5V (¬±100mV). This device supports simultaneous access to the same memory location from both ports, making it suitable for applications requiring high-speed data transfer and efficient memory management. The memory chip includes on-chip hardware for semaphore signaling and supports JTAG features compliant with IEEE 1149.1. It is available in multiple package types, including a 208-pin Plastic Quad Flatpack and various Ball Grid Array configurations. The device operates within an industrial temperature range of -40¬8C to +85¬8C, ensuring reliability in demanding environments. The 70V658S12BC is designed for applications that require fast, dual-port memory solutions without the need for additional external logic for depth expansion.
