Microchip Technology's 27HC256T-70-SO is a 256K x 16-bit OTP (One-Time Programmable) Read-Only Memory (ROM) device. This CMOS component offers an asynchronous operating mode with a maximum access time of 150ns. The memory organization of 256K words by 16 bits provides a total density of 4M bits. It features a 3-state output characteristic and common I/O. The device operates from a nominal supply voltage of 5V and is housed in a 28-terminal, rectangular, gull-wing Small Outline Package (SOP) with a terminal pitch of 1.27mm. Designed for surface mounting, it operates within a temperature range of 0°C to 70°C. Applications for this type of non-volatile memory include embedded systems, industrial control, and data storage in various electronic equipment.
