GENERAL DESCRIPTION
AKTP01/02 chassis series are applied A14T02/A14T02a respectively which uses mainly TOSHIBA’
advanced UOC-ultimate chip TMPA8803/8821/8851 and I2C-bus controlled IC with combination of
micro controller and small signal processor, the TMPA8803/8821/8851 series feature high-integration,
high performance-to-price ratio and high-reliability and advanced functions with fewer external
components, which provide much convenience for manufacturing and technical service.
