Quality Control: Learn More
The Intel P82C08-20 is a CMOS DRAM controller from the P82C08 series, featuring a 1M x 8 memory organization. This component operates with a 20 MHz clock frequency and supports up to an 18-bit address bus. It is designed for compatibility with the IAPX286 bus architecture and offers five programmable refresh modes for efficient memory management. The device supports two memory banks and includes a low-power mode. Packaged in a 48-lead PDIP (Plastic Dual In-line Package) with through-hole mounting, the P82C08-20 is suitable for applications requiring direct DRAM interface control, including computing and embedded systems. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal 5.0V, and has a maximum operating temperature of 70°C.
