HT46R47E/HT46C47E

Cost-Effective A/D Type 8-Bit MCU

Rev. 1.30

1

July 13, 2005

General Description

The HT46R47E/HT46C47E are 8-bit, high perfor-

mance, RISC architecture microcontroller devices spe-

cifically designed for A/D applications that interface

directly to analog signals, such as those from sensors.

The mask version HT46C47E is fully pin and function-

ally compatible with the OTP version HT46R47E de-

vice.

There are two dice in the HT46R47E/HT46C47E pack-

age: one is the HT46R47/HT46C47 MCU, the other is a

128

´8 bits EEPROM used for data memory purpose.

The two dice are wire-bonded to form HT46R47E/

HT46C47E.

The advantages of low power consumption, I/O flexibil-

ity, programmable frequency divider, timer functions,

oscillator options, multi-channel A/D Converter, Pulse

Width Modulation function, HALT and wake-up func-

tions, enhance the versatility of these devices to suit a

wide range of A/D application possibilities such as sen-

sor signal processing, motor driving, industrial control,

consumer products, subsystem controllers, etc.
