UNISONIC TECHNOLOGIES CO., LTD RCR2E Preliminary CMOS IC DECODER FOR REMOTE CONTROLLER WITH FIVE FUNCTIONS DESCRIPTION The UTC RCR2E provides a complete control functions to the remote-controlled toy. The UTC RCR2E has five output pins corresponding with the five actions. The received signals are amplified by the three-stage amplifier, and than the appropriate amplified signals are sampled, fault-tolerantly checked and decoded to control the actions of the remote-controlled toy. There is an internal oscillator in the UTC RCR2E respectively. By adding an external resistor conveniently, the oscillator will be constructed. The oscillator frequency can be adjusted by the external resistor. The relative error between the frequencies of the two on-chip oscillators in the UTC RCR2E must be less than ±25%. The auto-power-off function is achieved by an internal counter. The PC output is used to control on/off state of the external power supply. Pressing OFF button can also shut down the power supply. Press on any function button will wake up the chip promptly FEATURES * The UTC RCR2E works as decoder * RCR2E-A have not ZENER RCR2E-B built-in 3.6V ZENER * Five Pins for five control functions * Operating power-supply voltage: SOP-16: 2.0V ~ 5.0V, DIP-16: 2.5V ~ 5.0V * Auto-power-off if no press on any button in 8s or continuously press on any button over 4 minutes * Manual-power-off with OFF button * On-chip oscillator with an external resistor * On-chip reversing amplifiers * Low operating current ORDERING INFORMATION Order Number Lead Free Halogen Free RCR2EL-x-D16-T RCR2EG-x-D16-T RCR2EL-x-S16-T RCR2EG-x-S16-T RCR2EL-x-S16-R RCR2EG-x-S16-R Package Packing DIP-16 SOP-16 SOP-16 Tube Tube Tape Reel RCR2EL-x-S16-T (1)Packing Type (1) T: Tube, R: Tape Reel (2)Package Type (2) S16: SOP-16, D16: DIP-16 (3)Rank (3) x: refer to ICC (4)Lead Free (4) L: Lead Free, G: Halogen Free www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., LTD 1 of 7 QW-R502-894.a RCR2E Preliminary PIN CONFIGURATION VO2 GND SI OSCI OSCO RIGHT LEFT RD CMOS IC 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VI2 VO1 VI1 VDD TURBO FORWARD BACKWARD LD PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 PIN NAME VO2 GND SI OSCI OSCO Right Left RD LD Backward Forward Turbo VCC VI1 VO1 VI2 FUNCTION Output pin for the amplifier 2 Negative power supply Input pin of the encoding signal Oscillator input pin Oscillator output pin Rightward output pin Leftward output pin With Pull-up resistor, rightward function disabled if this pin connected to GND With Pull-up resistor, leftward function disabled if this pin connected to GND Backward output pin Forward output pin Turbo output pin Positive power supply Input pin for the amplifier 1 Output pin for the amplifier 1 Input pin for the amplifier 2 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 7 QW-R502-894.a RCR2E Preliminary CMOS IC BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 7 QW-R502-894.a RCR2E Preliminary CMOS IC ABSOLUTE MAXIMUM RATING (Above which the useful life may be impaired.
