The Microchip Technology 27HC256T-70-L is a 256Kbit, CMOS, One-Time Programmable (OTP) Read-Only Memory (ROM) organized as 32,768 words by 8 bits. This asynchronous memory device offers a maximum access time of 70 nanoseconds, facilitating rapid data retrieval. Featuring 3-state outputs, it ensures compatibility with various bus configurations. The component is housed in a 32-terminal PQCCJ (Plastic Chip Carrier) package, suitable for surface-mount applications. Its operating temperature range is 0°C to 70°C, with a nominal supply voltage of 5V. This device finds application in areas requiring fixed program storage, such as industrial control systems and legacy embedded designs. The 27HC256 series OTP ROMs are designed for efficient, non-volatile data retention.
