Microchip Technology's 27HC256-90-K is a 32768 x 8 bit CMOS EPROM featuring a 90ns maximum access time. This asynchronous memory device operates with a nominal supply voltage of 5V, ranging from 4.5V to 5.5V, and exhibits a maximum supply current of 55mA. The 27HC256 series component is housed in a 32-terminal CQCC (Ceramic Quad Flatpack) package, identified by the R-CQCC-N32 JESD-30 code. Its output characteristics are 3-state, facilitating efficient bus interfacing. This component finds application in industrial and telecommunications equipment requiring reliable, non-volatile program storage. The memory organization is 32K words by 8 bits, providing a total density of 262,144 bits.
