UM3302H/UM3302Q 2-Bit Bidirectional Voltage-Level Translator with Auto Direction sensing and ±15kV ESD Protection UM3302H CSP8 1.90×0.90 UM3302Q QFN8 1.40×1.20 General Description The UM3302, a ESD protected level translator, provides the level shifting necessary to allow data transfer in multi-voltage system. This 2-channel noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. Both I/O ports are auto-sensing; thus, no direction pin is required, making it ideal for data transfer between low-voltage ASICs /PLDs and higher voltage systems. The UM3302 operates at a guaranteed data rate of 20Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are up to 100Mbps. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. The UM3302 is designed so that the OE input circuit is designed to track VCCA. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull down resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The UM3302H is a dual channel level translator available in 1.90mm×0.90mm CSP8 bump package while UM3302Q is available in 1.40mm×1.20mm QFN8 package.

Externally applied voltages, VCCA and VCCB set the logic levels on either side of device. A low voltage signal present on VCCA side of the device appears as a high voltage logic signal on the VCCB side of the device, and vice-versa. Block Diagram The UM3302 (block diagram see Figure 1) does not require a direction-control signal to control the direction of data flow from A to B or from B to A. In a dc state, the output drivers of the UM3302 can maintain a high or low, but are designed to be weak, so that they can be overdriven by an external driver when data on the bus starts flowing the opposite direction. The output one shot detects rising or falling edges on the A or B ports. During a rising edge, the one shot turns on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly, during a falling edge, the one shot turns on the NMOS transistors (T2, T4) for a short duration, which speeds up the high-to-low transition. Figure 1 Block Diagram of UM3302 I/O Cell ________________________________________________________________________ http://www.union-ic.com Rev.07 Sep.2013 8/13 UM3302H/UM3302Q Input Driver Requirements Typical IIN vs VIN characteristics of the UM3302 are shown in Figure 2. For proper operation, the device driving the data I/Os of the UM3302 must have drive strength of at least ±2 mA. A: VT is the input threshold voltage of the UM3302 (typical VCCI/2) B: VD is the supply voltage of the external driver. Figure 2 Typical IIN vs VIN Curve Power Up During operation, ensure that VCCA≤VCCB at all times. During power-up sequencing, VCCA≥ VCCB does not damage the device, so any power supply can be ramped up first. The UM3302 has circuitry that disables all output ports when either VCC is switched off (VCCA/B = 0 V). Enable and Disable The UM3302 has an OE input that is used to disable the device by setting OE = low, which places all I/Os in the high-impedance (Hi-Z) state. The disable time (tdis) indicates the delay between when OE goes low and when the outputs actually get disabled (Hi-Z). The enable time (ten) indicates the amount of time the user must allow for the one-shot circuitry to become operational after OE is taken high. Pullup or Pulldown Resistors on I/O Lines The UM3302 is designed to drive capacitive loads of up to 50pF. The output drivers of the UM3302H have low dc drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be kept higher than 50kΩ to ensure that they do not contend with the output drivers of the UM3302. For the same reason, the UM3302 should not be used in applications such as I2C or 1-Wire where an open-drain driver is connected on the bidirectional data I/O. ________________________________________________________________________ http://www.union-ic.com Rev.07 Sep.2013 9/13 UM3302H/UM3302Q Typical Operating Circuit 1.8V 3.3V 0.1μF 1.8-V System Controller VCCA VCCB OE Data A1 Data GND A2 GND 3.3-V System B1 Data B2 Data GND 0.1μF Figure 3 Typical operating circuit Test Circuits Figure 4 Load Circuits and Voltage Waveforms ________________________________________________________________________ http://www.union-ic.com Rev.07 Sep.2013 10/13 UM3302H/UM3302Q Package Information UM3302H: CSP8 1.90×0.90 Outline Drawing A1 A e L D D1 b Symbol A A1 D E D1 E1 e b C L DIMENSIONS Millimeters Inch Min Max Min Max 0.65 0.026 0.21 0.24 0.008 0.010 1.85 1.95 0.074 0.078 0.85 0.95 0.034 0.038 1.50BSC 0.06BSC 0.50BSC 0.020BSC 0.50BSC 0.02BSC 0.27 0.32 0.011 0.013 0.25BSC 0.01BSC 0.25BSC 0.01BSC Land Pattern NOTES: 1.
