SDA2040

The SDA2040 is application-oriented single-chip microcomputer.

Features of the SDA2040 are:(1)upgraded 8-bit CPU as compared to SAB 8051;(2)+5V supply voltage;(3)1us internal cycle with 12MHz clock frequency;(4)input for direct modulated digital infrared signal processing;(5)powerful interrupt structure with 5 sources and 2 hierarchy levels;(6)instruction set downward-compatible with existing programs;(7)power-down mode with internal RAM data retention and reduced power consumption;(8)two 16-bit timer/counters;(9)instructions for direct multiplication or divison,execution time only 4us.

The absolute maximum ratings of the SDA2040 can be summarized as:(1)voltage between any pin and ground:-0.5V to 7V;(2)total power dissipation:2W;(3)storage temperature range:-40 to +125;(4)supply voltage:5±10%V;(5)ambient temperature:0 to 70.
