General Description
The HT49C30-1 and the HT49C30L are 8-bit high per-
formance single chip microcontrollers. The
HT49R30A-1 is the OTP version of the HT49C30-1. Its
single cycle instruction and two-stage pipeline architec-
ture make it suitable for high speed applications. The
devices are also suitable for use in multiple LCD low
power applications such as scales, leisure products,
high-level household appliances, hand held LCD prod-
ucts and batteries operated systems in particular.
