General Description
The HTG2190 is an 8-bit high performance RISC-like
microcontroller capable of driving 1024 pixel (max.)
LCD display. Its single cycle instruction and two-stage
pipeline architecture make it suitable for high speed ap-
plications. The device is suited for use in multiple LCD
· R to F function for temperature measurement
· Synchronous serial interface
· On-chip RC oscillator for system clock
· 32768Hz crystal oscillator for time base and LCD
driver
· Watchdog Timer
· HALT function and wake-up feature reduce power
consumption
· Eight-level subroutine nesting
· Bit manipulation instructions
· 63 powerful instructions
· Built-in supply voltage detection circuit
· One interrupt input
· 128-pin QFP package
low power applications among which are calculators,
clock timer, game, scales, leisure products, other hand
held LCD products and battery operated systems in par-
ticular.
