General Description
The HT49C10 is an 8-bit high performance single
chip microcontroller. Its single-cycle instruction
and two-stage pipeline architecture make it suit-
able for high speed applications. The device is
· Buzzer output
· Halt function and wake-up feature reduce
power consumption
· LCD driver with 19´3 or 18´4 segments
· 4-level subroutine nesting
· Bit manipulation instruction
· 14-bit table read instruction
· Up to 1ms instruction cycle with 4MHz
system clock
· 63 powerful instructions
· All instructions in 1 or 2 machine cycles
· 48-pin SSOP package
also suited for multiple LCD low power applica-
tions among which are calculators, clock timers,
games, scales, leisure products, other hand held
LCD products, and battery systems in particular.
