The M29W022B is a 2 Mbit (256Kb x8) non-volatile memory that can be read, erased and reprogrammed.
These operations can be performed using a single low voltage (2.7 to 3.6V) supply.
On power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or EPROM.
Compare M29W022BB distributor prices and check real-time stock availability from major suppliers. Prices and inventory may vary by region and order quantity.
