P83C434; P83C834
· Timer 0 external input replaced by a direct connection to the 32 kHz oscillator output. · Timer 1 external input is connected to pin P0.0 (Port 0); alternate function of P0.0. · Standard serial interface and its control register is not present. · Adjustable on-chip oscillator without external components. · Wake-up from Power-down mode is also possible by means of an interrupt. · Extended external interrupts. 1.2 Memory ROM/RAM sizes MEMORY DEVICE ROM P83C434 P83C834 2 4 kbytes 8 kbytes RAM 128 bytes 256 bytes
· 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. 1.1 Differences from the 80C51 core

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. This data sheet details the specific properties of the P83C434 and P83C834. The shared characteristics of the 80C51 family of microcontrollers are described in "Data Handbook IC20", which should be read in conjunction with this data sheet.
· Port 0 quasi-bidirectional instead of open-drain. · No external memory connection. Signals EA, ALE and PSEN are not present. · Port 1, Port 2 (pins P2.4 to P2.7) and Port 3 are not present. 3 ORDERING INFORMATION
