Differences 3.1 Secured Silicon Sector 128-word is not supported by Eon. 3.2 Manufacturer ID Eon’s device uses an extended manufacurer identification code at address 100h , instead of address 000h. Thus, on address 100h, the output is 1Ch ;while on address 000h, the output is 7Fh. 3.3 Autoselect command during erase suspend mode. The auto-select command sequence allows the host system to access the manufacturer and device codes, and determine whether or not a sector is protected. Normally, it is initiated from read mode. For EN29LV640T/B, in erase suspend mode while an erase operation has been suspended, the system can read data from any sector not selected for erasure. However, manufacturer and device codes can not be read out by writing auto-select command sequence during this period. In other words, Auto-select command is not supported during erase suspend mode in EN29LV640T/B, however S29GL064A supports it. 3.4 Page Read & Write buffer S29064A has 4-word/8-byte page read buffer and 16-word/32-byte write buffer in accordance with the commands, write-to-buffer, program-buffer-to-flash, and write-to-buffer-abort-reset. These are not available for EN29LV640T/B. 3.5 Continuous Sector Erasure Sector erase is a six bus cycle operation as defined in the datasheet of EN29LV640T/B. Once the sector erase operation has begun, only the erase suspend command is valid. All other commands are ignored. Unlike the devices from other vendors, only a single sector can be specified for each sector erase command. Users must issue another sector erase command for the next sector to be erased after the previous one is completed. 3.6 VID and VHH is 11.5V Max. VID applied to enable Signature (Auto-select) and sector(group) protection and VHH applied to Accelerated Program are between 10.5V and 11.5V. The same parameters for S29064M are 11.5V to 12.5V. Any voltage level higher than 11.5V would damage the device. This Application Note may be revised by subsequent versions or modifications due to changes in technical specifications. Rev.

Conclusion EN29LV640T/B are compatible with Spansion S29GL064A on the major features. Moreover Eon has faster word program time 8μs (Spansion 15us) and lower active read current 9mA, ( Spansion 18mA ) which is more useful in practice. Note: 1.
