Description
AT27C256R-45PU Overview
Non-Volatile is the type of memory it has. The case comes in Tube size. There is a 28-DIP (0.600, 15.24mm) case embedded in it. A memory chip with a capacity of 256Kb 32K x 8 is used on this device. There is a EPROM-format memory used in this device, which is the memory format used by mainstream devices. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. It is capable of handling a voltage supply of 4.5V~5.5V. There is a recommended mounting type of Through Hole for it. It is planted on the chip with 28 terminations. It supports up to 1 functions for comprehensive operation. A voltage of 5V is required for the operation of this memory device. As the base part number for the device, AT27C256 is frequently used to select similar items. The memory device is enclosed in a package with an 28-pin connector. This memory chip has an operating supply voltage of 5V. Memory chips configured with Through Hole mounting achieve high efficiency and simplicity. As far as the nominal supply current of this memory component is concerned, it is rated at 20mA. This memory chip requires a mere 5V of power. This device has COMMON-bit memory mapped I/O port addresses. OTP ROMs components are usually considered types of this component. There is a frequency of 45GHz for the data to be processed on this memory chip. In terms of voltage, the chip performs well under a voltage of 7V volts. Devices operating at 100μA volts are recommended.
