DESCRIPTION The UTC 1616 is a CMOS design for 6 different alarm sounds application. The sound of UTC 1616 will be generated in cycling sequence. The soft chirp is only generated within 200ms of the 1st sound. By the way, UTC 1616 is also partitioned for single tone siren/alarm sound generator with soft chirp, 1616A. The types of UTC 1616 Series are listed as following. 1616: 6 tones with 200ms soft chirp in the 1st sound. 1616A: Single tone with 200ms soft chirp on chip.
FEATURES * Low operating voltage: 2V ~ 5V. * On-chip RC oscillator. * Low stand by current. * CMOS process.
OVERVIEW The CF5761 series are analog clock ICs with alarm functions that derive their timing from a standard 32.768kHz oscillator element. Two kinds of alarm output are available and can be selected using a control pin. The series lineup comprises devices with various alarm patterns and motor outputs for a wide range of clock specifications. They support convenient functions, such as input chattering elimination circuit and power-on clear functions. They are fabricated using Molybdenum-gate CMOS process, realizing low power consumption.
FEATURES ■ 32.768kHz fundamental frequency oscillator ■ Feedback resistor and oscillator capacitor CD built-in ■ Supports various alarms: piezo-alarm, electromagnetic speaker ■ Snooze function ■ Switchable alarm function using SEL pin ■ alarm auto-stop function (see series lineup) ■ Input chattering elimination circuit (SEL, AI, SN) ■ Test function ■ 1.2 to 3.6V operating supply voltage ■ Molybdenum-gate CMOS process ■ chip form (CF5761××)
Overview Both the LM8560N and LM8560B are alarm equipped digital clock ICs with built-in drivers capable of directly driving LED display equipment. AS ICs themselves, the VDD pin for the LM8560N is graded to withstand a voltage of 15V while the LM8560B VDD is graded for up to 17V.
Applications ● alarm clocks ● Clock-radios
Functions ● Current time display ● Snooze alarm function ● Sleep timer function (maximum intervals of 59 minutes or 1 hour and 59 minutes)
