UNISONIC TECHNOLOGIES CO., LTD UL0512 Preliminary CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2021 Unisonic Technologies Co., Ltd QW-R125-103.a LANDSCAPE LIGHTING DRIVE IC DESCRIPTION The UTC UL0512 is a three-channel LED drive control IC using single channel transmit the unipolar return-to-zero(RZ) code data protocol. The UTC UL0512 contains power clamp module, signal decoding module, oscillation m odule, data regeneration module, output current drive module etc. A fter receiving its own data, the data regeneration module will automatically shape and forward the cascaded data to ensure that the data is not attenuated in the process of serial transmission. The UTC UL0512 builds in output current setting module, the default output current of OUT R/G/B is 12mA. FEATURES * Input Voltage: 3.5V~5.5V * OUT R/G/B Constant Current: 12mA * OUT R/G/B Output Gray Level: 256 * OUT R/G/B Power-on state: OFF * Build in high precision and high stability oscillator * Serial data transmission * Shaping the cascade data before output to prevent attenuation * Data transmission rate : 800Kbps * Synchronous refresh of display data in the same frame DIP-8 ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free UL0512L-D08-T UL0512G-D08-T DIP-8 Tube (1) T: Tube (2) D08: DIP-8 (3) G: Halogen Free and Lead Free, L: Lead Free UL0512G-D08-T (1)Packing Type (2)Package Type (3)Green Package MARKING

The UTC UL0512 protocol uses unipolar return-to-zero (RZ) code, and each code element must have low level. Each code element of this protocol starts at high level, and time of this high level determines the 0 code or 1 code. Figure 2. UTC UL0512 RZ-code data communication protocol diagram Notes: 1. When writing programs, the minimum code element period requirement is 1.2μs.
- The high level time of 0 code 、1 code shall be in accordance with the above table, and the low level time
requirement of 0 code、1 code is less than 20μs.
- 24bit data structure of gray level: MSB, sending in the order of RGB
- Input data stream of each chip (Take three chips as an example)
