Note: 1. Part numbers including "C" are mask version devices,
"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. |
