There are two dice in the HT46R48E package: one is the HT46R48 MCU, the other is a 128´8 bits EEPROM used for data memory purpose. The two dice are wire-bonded to form HT46R48E. The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, Pulse Width Modulation function, HALT and wake-up functions, enhance the versatility of these devices to suit a wide range of A/D application possibilities such as sensor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc. Rev. 1.10 March 24, 2006 Block Diagram P A 5 /IN T In te rru p t C ir c u it S T A C K P ro g ra m R O M P ro g ra m C o u n te r IN T C T M R C T M R P A 3 /P F D In s tr u c tio n R e g is te r M U X P A 4 M U X f S P r e s c a le r P A 4 /T M R f...
