3.2 Max VID comparison
S29GL064N VID range is 11.5V ~ 12.5V. But EN29GL064H/L/T/B doesn’t support VID
function. Any voltage level higher than chip spec would damage the device, possibly.
(Using high voltage on Address9 enters autoselect mode)
3.3 Different VHH level (for accelerating programming functions)
EN29GL064H/L/T/B voltage level: 8.5V ~ 9.5V.
S29GL064N voltage level: 11.5 ~ 12.5V.
3.4 Different VIO level (for adjusting different I/O voltage range)
EN29GL064H/L/T/B voltage level: 1.65V ~ 3.6V.
S29GL064N: 1.65V ~ 3.6V
3.5 Different random access speed
EN29GL064H/L/T/B: 70ns @ full VCC range: 2.7V ~ 3.6V.
S29GL064N: 100ns or 110 ns @ full VCC range / 90 ns. (When VCC is used between
3.0V ~ 3.6V)

4.2. Password protection commands
EN29GL064H/L/T/B: No support.
S29GL064/N: Support.
4.3. Multi-sector erasure commands
EN29GL064H/L/T/B: No supported. (Users must issue another sector erase command
for the next sector to be erased after the previous one is completed)
S29GL064N: Support.
4.4. Different PPB protect range
EN29GL064H/L: Sector 0~3 and 124~127 have PPB for each sector. Sector 4~123 are
1 PPB per 4 sectors.
EN29GL064T: Sector 0~123 are 1 PPB per 4 sectors. Sector 124~134 have PPB for
each boot sector.
EN29GL064B: Sector 0~10 have PPB for each boot sector. Sector 11~134 are 1 PPB
per 4 sectors.
S29GL064/N: A Persistent-Protection-Bit (PPB) is assigned to each block.
