AT27HC256R

AT27HC256R Series Datasheet

The ATMEL AT27HC256R/RL chip family is a high-speed, low-power 262,144 bit Ultraviolet Erasable and Electrically Programmable Read Only-Memory (EPROM) organized as 32K x 8 bits. The AT27HC256R is suited for very high-speed applications, while the AT27HC256RL features low Vcc Standby Current. Both Require only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 55ns on the AT27HC256, making this part ideal for high-performance systems. Power consumption is typically only 35mA in Active Mode on both parts, and less than 20µA in Standby Mode on the AT27HC256RL or 15mA on the AT27HC256R.
