Preliminary
GENERAL DESCRIPTION
EM73675 is a highly-integrated digital answering machine controller in which control function and signal
amplification capability are integrated into a monolithic device. The EMC EM73400 based 4-bit controller
contains 6K-byte ROM, 244-nibble RAM, 5 interrupt sources, a melody generator, two 12-bit timer/counters,
a time-based interrupt and 14 general purpose I/O pins to provide interfaces with keyboard, LED display, DAA
circuit, tape mechanism and DTMF detection circuit etc. Total component counts and production cost can
therefore be reduced.
The linear amplifier portion combines all necessary amplifiers with Automatic Level Control function for
signal amplification and conditioning, analog switches and digital attenuator, designed to provide the most
integrated design for the Single Deck Tape-Based Telephone Answering Device applications.
