AT28HC256-70SU Product Details
AT28HC256-70SU Overview
Non-Volatile is the type of memory it has. The case comes in Tube size. The 28-SOIC (0.295, 7.50mm Width) case contains it. On the chip, there is an 256Kb 32K x 8 memory, which is the size of the chip's memory. Memory data is stored in EEPROM-format, which is common in mainstream devices. With an extended designed operating temperature of -40°C~85°C TC, this device is capable of lots of demanding applications. A voltage of 4.5V~5.5V can be supplied to memory ics. Its recommended mounting type is Surface Mount. It is planted on the chip with 28 terminations. There are 1 functions supported by this part as part of the comprehensive working process. This ic memory chip is designed to be supplied with 5V. As the base part number for the device, AT28HC256 is frequently used to select similar items. In this ic memory chip, there is an 28-pin package that encloses the device. This memory's operating supply voltage is 5V. As a result of the Surface Mount mounting configuration, this chip is designed to be straightforward, high-efficiency, and easy to install. The nominal supply current of this memory component is 80mA. In terms of power requirements, this memory chip uses only 5V . 5V programming voltage is required to change the state of certain nonvolatile memory arrays. This memory chip processes data at a frequency of 5MHz.
