Note: 1. Part numbers including
²C²
are mask version devices,
²R²
are OTP devices, while part numbers suffixed with
²L²
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.
