UNISONIC TECHNOLOGIES CO., LTD RCR2E Preliminary CMOS I C www.unisonic.com.tw 1 of 7 Copyright © 2013 Unisonic Technologies Co., LTD QW-R502-894.a 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 amplifie r, 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 constr ucted. 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 Package Packing Lead Free Halogen Free RCR2EL-x-D16-T RCR2EG-x-D16-T DIP-16 Tube RCR2EL-x-S16-T RCR2EG-x-S16-T SOP-16 Tube RCR2EL-x-S16-R RCR2EG-x-S16-R SOP-16 Tape Reel RCR2EL-x-S16-T (1)Packing Type (2)Package Type (3)Rank (4)Lead Free (1) T: Tube, R: Tape Reel (2) S16: SOP-16, D16: DIP-16 (3) x: refer to I CC (4) L: Lead Free, G: Halogen Free
