Overview
The LC737212 and LC737212M are CMOS LSI
telephone dialers for pushbutton telephones. They support
both DTMF and pulse dialing. These products include 25
16-digit memories for storing telephone numbers and one
63-digit memory for redialing, and they provide, in a
single chip, all the functions required for dialing and
control for a standard independent telephone, including
on-hook dialing and a hold function. They also provide a
serial I/O interface for connection to a microcontroller.
Functions
• Fabrication in a CMOS process that allows these circuits
to be directly operated from a telephone line
• Support for single-contact keypads
• Built-in oscillator circuit (fosc = 3.58 MHz) that can
drive either a standard color-TV crystal oscillator
element or a ceramic resonator
• High-precision DTMF signal
• Frequency generator circuit (±0.1%) adopted for eased
ceramic resonator selection
• Five one-touch 16-digit auto-dial memories and 20
quick-dialing memories
• On-hook or off-hook can be specified for memory
entries.
• Mode change and pause data items can be stored in the
dialing memories.
• 63-digit redial memory
• Automatic pause (3.9 seconds) insertion when the mode
is switched.
• Automatic pause (1.0 second) insertion after a flash
operation.
• Mode changing is one-directional, from pulse mode to
tone mode.
• Output of a key press tone (1036 Hz, 31 ms) for keys
other than DTMF keys when key input is valid
• Output of an operation complete confirmation tone
(2072 Hz, 279 ms for each telephone number) when a
telephone number is stored in memory
• Generates 12 signal types in DTMF mode.
• Supports an on-hook dialing mode.
• Supports a hold function with hold mode.
• Supports both 10 and 20 pps dialing pulse rates.
• The mode can be switched from either the P/T pin or by
a key input.
• Settable dialing pulse circuit closed ratio (make
percent): either 33% or 39%.
• Supports either keypad or serial input.
• Provides serial output of the keypad input data and the
internal status.
• Capable of controlling the serial output timing.
• Supports 18 user-defined keys.
• Wide operating power-supply voltage range
— Pulse mode: VDD = 1.5 to 5.5 V
— DTMF mode: VDD = 2.0 to 5.5 V
• Low power operation
— Pulse mode: IDD = 0.5 mA max (VDD = 3.0 V)
— DTMF mode: IDD = 1.0 mA max (VDD = 3.0 V)
• Low standby current
—IDR = 0.5 µA max (VDD = 1.0 V)
