Manufacturer:TI Description:The M59PW064 is a 64Mbit (4Mbx16), Mask- ROM pin-out compatible, non-volatile LightFlash memory, that can be read, erased and reprogrammed. Read operations can be performed using a single low voltage (2.7 to 3.6V) supply. Program and Erase operations require an additional VPP (11.4 to 12.6V) power 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. The memory is divided into 32 uniform blocks that can be erased independently so it is possible to preserve valid data while old data is erased (see Table 2., Block Addresses). Program and Erase commands are written to the Command Interface of the memory. An on-chip Program/Erase Con- troller (P/E.C.) simplifies the process of program- ming or erasing the memory by taking care of all of the special operations that are required to update the memory contents. |
