PT2264 Remote Control Encoder IC DESCRIPTION PT2264 is a remote control encoder utilizing CMOS Technology. It encodes data and address pins into a serial coded waveform suitable for RF modulation. PT2264 has a maximum of 12-bit of tri-state address pins providing up to 531,441 (or 312) address codes; thereby, drastically reducing any code collision and unauthorized code scanning possibilities. APPLICATIONS FEATURES CMOS technology Low power consumption Very high noise immunity Up to 12 Tri-State code address pins Up to 4 data pins Wide range of operating voltage: VCC=8 ~ 15V Single resistor oscillator Latch or momentary output type Available in DIP and SOP package Remote control fan Home security/Automation system Remote control toys Remote control for door bell BLOCK DIAGRAM A0 System Tim ing A1 OSC1 OSC OSC2 A2 A3 A4 A5 A6 Address Contr ol Logic /TE A7 A8/D3 A9/D2 A 10/D1 A 11/D0 Code Generation DOUT Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, 233-1, Baociao Road, Sindian Dist., New Taipei City 23145, Taiwan PT2264 ORDER INFORMATION Valid Part Number Package Type Top Code PT2264-S SOP, 300mil, 20pins PT2264-S PT2264-18S PT2264 SOP, 300mil, 18pins DIP, 300mil, 18pins PT2264-18S PT2264 PIN CONFIGURATION A0 1 18 VC C A0 1 20 VC C A1 2 17 DOUT 2 19 DOUT A2 3 16 OSC2 A1 A2 3 18 OSC2 A3 4 15 OSC1 A3 4 17 OSC1 A4 5 14 /TE A4 5 16 /TE A5 6 13 A11/D0 A5 6 15 A11/D0 A6 7 12 A10/D1 A6 14 A10/D1 A7 8 11 A9/D2 A7 7 8 13 A9/D2 VSS 9 10 A8/D3 VSS 9 12 A8/D3 10 11 NC NC PT 2264 P T2264-18S V1.2 PT 2264-S -2- January, 2016 PT2264 PIN DESCRIPTION Pin Name I/O A0 I Pin No. 18 20 1 1 A1 I 2 2 A2 I 3 3 A3 I 4 4 A4 I 5 5 A5 I 6 6 A6 I 7 7 A7 I 8 8 A8/D3 I 10 12 A9/D2 I 11 13 A10/D1 I 12 14 A11/D0 I 13 15 /TE I 14 16 OSC1 O 15 17 OSC2 I 16 18 DOUT O Data Output Pin. The encoded waveform is serially outputted to this pin. When PT2264 is not transmitting, DOUT outputs low (VSS) voltage. 17 19 VCC Power Supply Positive Power Supply 18 20 VSS Power Supply Negative Power Supply 9 9 No connection - 10,11 N.C V1.2 Description These ten tri-state pins are detected by PT2264 to determine the encoded waveform bit 0 - bit 9. Each pin can be set to “0”, “1” or “f” (floating). These four tri-state pins are detected by PT2264 to determine the encoded waveform bit 10, bit 11. When these pins are used as address pins, they can be set to “0”, “1”, or “f” (floating). When these pins are used as data pins, they can be set only to “0” or “1”. Transmission Enable. Active Low Signal. PT2264 outputs the encoded waveform to DOUT when this pin is pulled to low. A resistor connected between these two pins determine the fundamental frequency of the PT2264. -3- January, 2016 PT2264 IMPORTANT NOTICE Princeton Technology Corporation (PTC) will issue official documents to have customers’ approval in advance, when we need to make corrections, modifications, enhancements, improvements, and other changes of the products and to discontinue the product.
