General Description
The HT46R48E are 8-bit, high performance, RISC ar-
chitecture microcontroller devices specifically designed
for A/D applications that interface directly to analog sig-
nals, such as those from sensors.
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 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.
