The Microchip Technology 27HC256L-55I-VS is a 262,144 bit, CMOS, One-Time Programmable (OTP) Read-Only Memory (ROM) organized as 32K words by 8 bits. This component offers a maximum access time of 55 nanoseconds, facilitating high-speed data retrieval. Operating across a temperature range of -40°C to +85°C, it features a 5V ±10% supply voltage. The 27HC256L-55I-VS is housed in a 28-lead TSOP (Type 1) package with a 0.55mm terminal pitch, suitable for surface-mount applications. Its asynchronous operation and 3-state outputs provide design flexibility. Typical applications for this memory device include industrial control systems, legacy system upgrades, and embedded computing platforms where non-volatile program storage is required. The standby current is rated at 100µA, with a maximum active supply current of 65mA.
