Norflash chip erase
WebThe Chip Erase instruction sequence is shown in Figure 20. The /CS pin must be driven high after the eighth bit has been latched. If this is not done the Chip Erase instruction will not be executed. After /CS is driven high, the self-timed Chip Erase instruction will commence for a time duration of tCE. While the Chip Erase cycle is in progress ... Webflash memory contains multiple sector sizes, but the Addr ess 21h definition corresponds to the time taken to erase the largest sector size of the device. Addresses 22h and 26h define the typical and maximum timeout values of the chip erase operation in milliseconds. Typical time = 2N ms and maximum time = 2N times typical. 3.3 Device Geometry ...
