The UTC 6610 is a frequency and clock display driver
used for displaying FM/AM radio frequency or a 12 hour
alarm clock. By using CMOS technology, it consumes very
low power in clock display mode.
FEATURES
* FM input with pre-scalar for radio frequency up to 150
MHz
* AM input for radio frequency up to 30 MHz
* 3 common, 13 segment, 1/3 bias LCD display drivers
which supports 4 digits LCD display
* On chip oscillator for external 32.768kHz crystal
* 10.7 MHz / 70 kHz I.F. frequency offset for FM signal and
455kHz I.F. frequency offset for AM signal
* Internal real time clock in 12 hour display mode
* Selectable clock or frequency display
* 1.8V to 3.3V supply voltage

FUNCTIONAL DESCRIPTION
1. RADIO FREQUENCY DISPLAY OPERATION (DTS MODE):
The FM and AM local oscillator output generated from the external RF receiver enters a high gain input
comparator through the FMIN and the AMIN pins respectively. The FM signal then routes through a divide-by-
10
dynamic pre-scalar. Depending on the state of the AM/FM-SEL pin, the FM and AM signal will be selected and
enters the IF frequency offset block. Depending on the FM/AM selection, 10.7MHz/70kHz or 455kHz
I.F.frequency will be subtracted or added from the input signal.

2. CLOCK FUNCTION:
(1) The clock will be advanced in the following flow:
PM 12:00 → PM 11:59 → AM 12:00 → 11:59
(2) The [:] sign is the second indicator and will blink at a rate of 2Hz
(3) TIME SETTING:
-- Pressing the keys combination of [TIME SET] [HR SET] or [TIME SET] [MIN SET] will enter the time
setting mode.
-- One digit will be incremented after entering the alarm setting mode. Keep pressing the keys
combination for more than 0.5 seconds will make the digit to be advanced at a rate of 2Hz.
(4) ALARM TIME SETTING:
-- Pressing the keys combination of [AL DISP] [HR SET] or [AL DISP] [MIN SET] will enter the alarm time
setting mode. The [AL] indicator will turn on and the [:] sign will stop blinking.
-- One digit will be incremented after entering the alarm setting mode. Keep pressing the keys combination

for more than 0.5 seconds will make the digit to be advanced at a rate of 2Hz.
(5) ALARM FUNTION:
-- AL OUT output pin will output an alarm frequency of 1024Hz at 0.2 sec on and 0.2 sec off.
-- AL OUT pin can be used to direct drive a piezo buzzer.
-- When alarm is active, AL OUT output can be disabled by pressing the [AL-ON/OFF] key or it will turn
off automatically after 3 minutes lapse.
-- AL-SIG pin is an open drain output (active low). Once alarm is activated, AL-SIG can be disabled by
pressing [AL-ON/OFF] key or it will turn off automatically after one hour time lapse.
-- When [AL DISP] is pressed, alarm setting time will be displayed on the LCD and the [AL] indicator will
be on.
-- The [AL-ON/OFF] pin will toggle the [

(6) 32.768kHz crystal is used for the reference frequency.
(7) After Power-on-reset (RST):
-- [HR SET] and [MIN SET] keys will be disabled.
-- [AL-DISP] KEY,[AL-ON/OFF] KEY AND AL-SIG output will be enabled.
3. After POWER-ON-SET(RST):
-- When in clock mode, it will display and start at AM 7:00.
-- When in DTS frequency mode, if CLKFREQ-SEL = High, and FMIN & AMIN pins are grounded, all LCD
segments will be turned on(LCD test mode).
