GENERAL DESCRIPTION

The P83C434 and P83C834 are low-cost microcontrollers of the 80C51 family, with LCD drivers. Main application is in the user-interface (keypad, display) of consumer products, e.g. portable radios, CD-players, etc.

FEATURES

• 80C51 type core

• System clock derived from an internal free running Current Controlled Oscillator (CCO); no external components required. Clock frequency can be adjusted by software.

• Optimized for EMC (Electromagnetic Compatibility)

• Clock frequency fclk = 1 to 12 MHz

• 12 I/O lines, quasi-bidirectional

• Gated interrupt on 8 I/O lines:

– P0.0 to P0.3 when LOW

– P0.4 to P0.7 when LOW or HIGH

• LCD driver clock, 32 kHz, which also provides the time base for a Real Time Clock

• 1-second interrupt by internal 15-bit counter

• On-chip Liquid Crystal Display (LCD) drivers with 26 outputs, comprising:

– 22, 23 or 24 segment drivers

– 1 to 4 backplanes

• LCD multiplexing rates: 1 : 1 (static), 1 : 2, 1 : 3 or 1 : 4

• Operating temperature: −40 to +85 °C

• Single power supply:

– Operating voltage: 3.5 to 5.5 V

– Power-down mode: 1.8 V.
