* Under development, available in 2Q, 2006
Note:  1. Part numbers including “C” are mask version devices while “R” are OTP  devices, while part numbers suffixed with “L” are low voltage mask version  devices
     2. For the low voltage mask version devices, note that the HT49R30A-1, HT49R50A-1 and HT49R70A-1 devices can be used as corresponding OTP devices
