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.
