Microchip Technology's 27HC256L-70-VS is a 262,144-bit, CMOS, One-Time Programmable (OTP) Read-Only Memory organized as 32,768 words by 8 bits. This device offers a maximum access time of 70ns, enabling efficient data retrieval in high-speed applications. Operating from a nominal 5V supply voltage (4.5V to 5.5V range), it features asynchronous operation with 3-state outputs. The component is housed in a 28-terminal, rectangular, plastic/epoxy, surface-mount package (TSOP1) with a 0.55mm terminal pitch. The 27HC256 series is commonly found in industrial control, telecommunications infrastructure, and consumer electronics where fixed program storage is required. The standby current is specified at 100µA maximum, with a typical operating supply current of 55mA maximum.
