AT28HC256-12JI memories are a type of static random access memories (SRAM) integrated circuits used in electronic applications. The SRAM circuit utilizes an array of memory cells consisting of flip-flops connected in associative pairs to store binary data. They are used for storing data and instructions for many different types of electronic hardware.For many applications, AT28HC256-12JIs are the preferred memory device due to their low power consumption, wide operating temperature range, low chip count, and high density. Their low power consumption makes them suitable for portable or battery-powered applications such as cell phones and handheld devices. The wide operating temperature range allows them to be used in temperatures up to 125°C. This makes them ideal for automotive and industrial applications. The low chip count and high density make them ideal for projects with limited space and power, such as embedded systems.The AT28HC256-12JI is an 8K x 8-bit static RAM which has been designed specifically for low-power operation. It is available in a variety of packages from a 16-pin DIP up to a 44-pin PLCC.The AT28HC256-12JI can be operated in either static or asynchronous mode. In static mode, the device is completely static, requiring no clock signal and consuming minimal power. In asynchronous mode, the device is clocked and may enter true asynchronous operation at clock rates up to 10 MHz.The AT28HC256-12JI also offers data protection features in the form of Write Protect and Data Latch/Write Enable. The Write Protect feature prevents accidental writes or erasures of stored data and the Data Latch/Write Enable allows data to be written to or rewritten to specific memory locations while protecting data located in other memory locations. The AT28HC256-12JI also offers a wide array of programming features to enable designers to create robust and low-power applications. These include Block Protection and Patches that provide extra functionality and functionality upgrades, Long Data Burst which enables faster data transfer rates, Mode Change Exception handling which allows specific code segments to be monitored and temporarily disabled, and Spillover Detection which prevents data overflow and data loss.The AT28HC256-12JI utilizes a standard architecture for static RAM devices and is based on an array of one-transistor memory cells arranged in rows and columns. Each memory cell consists of a static flip-flop and an address decoder. The combination of the static flip-flop and the address decoder allows for the address to be provided and the data stored at that location to be retrieved.The AT28HC256-12JI is a reliable and cost-effective solution for both consumer and industrial applications. It offers low power consumption, wide operating temperature range, high-density memory and is available in a variety of packages. Its wide range of programming features make it suitable for a variety of applications such as embedded systems and automotive. The AT28HC256-12JI is an ideal choice for applications which require reliable and low power static RAM.
