General Description
The HT45R04 is an 8-bit high performance, RISC archi-
tecture microcontroller devices specifically designed for
A/D applications that interface directly to analog signals,
such as those from sensors.
There are two dice in the HT45R04E package: one is
the HT45R04 MCU, the other is a 128´8 bits EEPROM
used for data memory purpose. The two dice are
wire-bonded to form HT45R04E.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, multi-channel A/D Converter, HALT
and wake-up functions, enhance the versatility of these
devices to suit a wide range of A/D application possibili-
ties such as security systems, smoke detectors, smart
tags, etc.
