LCD Type MCU
The HT49C30L, HT49C50L and HT49C70L are all low voltage versions of the LCD Type MCUse-
ries. With the ability to operate at a minimum low voltage power supply of only 1.2V these devices
are extremely suitable for single cell battery applications. Although they are only available as
mask versions, their sister OTP devices, the HT49R30A-1, HT49R50A-1 and the HT49R70A-1
are fully compatible and available for use during product development.
