AT29C256-70PI is a CMOS non-volatile memory chip. It has a block architecture with 27512 X 8 bits of erasable code (EPROM) organized in 1,048,576 bits of word-wide organization. The AT29C256-70PI chip is commonly used in memory products, such as ROM, EPROM, RAM, and flash memory.

The AT29C256-70PI chip is a 64K x 8-bit memory efficient and convenient for low power, high speed, and low pin count applications. It has a fast access time of 70ns and a low power consumption of less than 25 mW. The parts also have a wide operating temperature range (-40° to +85°C). Its main features include the following:

• 256Kbytes of memory with access time of 70 ns
• 128Kbytes of non-volatile memory with access time of 70 ns
• Data bus size of 8 bits
• Low standby current
• Maximum data retention of 100 years
• Softwear-selectable fast page mode

The AT29C256-70PI chip is widely used in applications such as embedded systems, consumer electronics, automotive, medical and industrial applications. Due to their high reliability, low power consumption and fast access time, the AT29C256-70PI chip is a popular choice in the semiconductor marketplace.

The AT29C256-70PI chip works by using a single +5V power supply and is programmed through an external programming voltage (typically 12V). The chip also has a 5V write enable/disable pin that is used to enable programming during programming and disables programming when not programming.

When the AT29C256-70PI chip is first powered up, the chip is put into an unprogrammed state in which the chip is ready to be programmed. Then the chip is programmed by writing data to the memory location that needs to be programmed. After the block sector has been programmed, the chip will enter the Verify Mode, where the contents of the memory location are checked to ensure that it was written correctly. If the data is correct, then the chip is ready for use.

The AT29C256-70PI chip is programmed using an externally provided programming voltage. This voltage is provided by the user, typically through an on-chip programming mode pin. Once the programming voltage has been supplied, the programming process begins. The chip is then programmed according to the instructions provided. Once the instructions have been completed, the chip is ready for use.

The AT29C256-70PI chip is capable of performing erase operations through an erase enable/disable pin. This pin is used to enable or disable programming and erase operations. When the erase pin is active, the erase operation is executed. Once the erase operation has been completed, the chip is ready for use.

The AT29C256-70PI chip is a reliable and cost-effective solution for embedded and non-volatile memory applications. Its low power consumption, fast access time, and wide operating temperature range make it an ideal solution for a wide range of applications. The parts have a long service life, are easy to use, and are RoHS compliant, making them a popular choice among electronics manufacturers.
