M27C4001-15C1

M27C4001-15C1 is an IC (integrated circuit) component manufactured by various electronic component companies, such as STMicroelectronics. It is a 4 Megabit (4 Mb) UV-erasable and electrically programmable EPROM (erasable programmable read-only memory) with a speed grade of 150 ns. Here are some key features and details: 1. Memory Capacity: The M27C4001-15C1 has a storage capacity of 4 Mb, which is equivalent to 512 Kilobytes (KB). It consists of 512 K x 8 bits, meaning it can store 512,000 8-bit bytes of data. 2. Erasable and Programmable: The IC uses the EPROM technology, which allows it to be both electrically programmable and UV-erasable. This means that the chip can be written or programmed with data electronically, and it can also be erased using ultraviolet (UV) light for reprogramming. 3. Speed Grade: The M27C4001-15C1 has a speed grade of 150 ns, which refers to the time it takes for the chip to access and retrieve data. This indicates that the component can perform read operations at a rate of 150 nanoseconds. 4. Voltage Requirements: The IC operates on a power supply voltage range of 4.5 to 5.5 volts (V)
