FXM2IC102 2-Bit I2C Bus Interface Voltage Translator / Repeater Features Description ƒ Bi-Directional Interface between any Two Levels from 1.65V to 5.5V ƒ Auto-Direction Sensing, Direction Control not Needed The FXM2IC102 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation over a wide range of input and output voltage levels. ƒ Buffer Isolates Capacitance and Allows 400pF on Each Port ƒ ƒ ƒ Open-Drain Inputs/Outputs ƒ Fully Configurable: Inputs and Outputs Track VCC Level ƒ Non-Preferential Power-up; Either VCC May be Powered Up First Schmitt Trigger Data Inputs Accommodates Standard-Mode and Fast-Mode 2 I C-bus Devices ƒ Outputs Remain in 3-State until Active VCC Level is Reached ƒ ƒ ƒ ƒ Power-Off High Impedance ƒ ESD Protection Exceeds: Active HIGH Output Enable Referenced to VCCA 5V-Tolerant Output Enable Packaged in 8-Terminal Leadless MicroPak™ (1.6mm x 1.6mm) The FXM2IC102 is intended for use as a voltage 2 translator in applications using the I C bus interface. 2 Input and output voltage levels are compatible with I C device specification voltage levels. The device is designed so that the A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi-directional voltage translation over voltage ranges: 1.8V, 2.5V, 3.3V, and 5.0V. The device remains in 3-state until both VCCs reach active levels, allowing either VCC to be powered up first. Internal power-down control circuits place the device in 3-state if either VCC is removed. The two ports of the device have auto-direction sense capability. Either port may sense an input signal and transfer it as an output signal to the other port. Schmitt triggers are used on data inputs for signal noise suppression. Typically the inputs have 100 millivolts of hysteresis over the full VCC range. The FXM2IC102 typically consumes only 230nA during 2 “no I C data transactions” when VCCA = 1.8V and VCCB = 3.3V. See Figure 4 and Figure 5 for more details. 2 ‚ ‚ 8kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7) 15kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7) FXM2IC102 exhibits robust I C repeater performance due to strong current sinking capability in > 400pf bus segments.

This benefit derives from the chip design. When either VCC is at 0V, outputs are in a high-impedance state. The control input (OE) is designed to track the VCCA supply. A pull-down resistor tying OE to GND should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull-down resistor is based upon the current-sinking capability of the device driving the OE pin. 1. Apply power to the first VCC. 2. Apply power to the second VCC. 3. Drive the OE input HIGH to enable the device. The recommended power-down sequence is: 1. Drive OE input LOW to disable the device. 2. Remove power from either VCC. 3. Remove power from other VCC.

Application Circuit Application Notes The FXM2IC102 has open-drain outputs and requires pull-up resistors on the four data I/O pins, as shown in Figure 3. If a pair of data I/O pins (An/Bn) is not used, both pins should be tied to GND (or both to VCC). In this case, pull-down or pull-up resistors are not required. © 2008 Fairchild Semiconductor Corporation FXM2IC102 • Rev. 1.0.2 The recommended values for the pull-up resistors (RPU) are 1kΩ minimum to 10kΩ maximum. The recommended value for the bypass capacitors (CBP) is 0.1µF. The recommended value for the pull-down resistor (RPD) on OE is 1kΩ or higher and may depend upon the current-sinking capability of the device driving the OE pin. www.fairchildsemi.com 4 2 transactions. In Figure 4, VCCB = 5.5V and in Figure 5, VCCB = 3.3V. For example, to translate from 1.8V to 3.3V (Figure 5), 2 with no I C data transactions present, the total ICC of the FXM2IC102 is typically only 230nA. In effect, the 2 FXM2IC102 virtually powers itself down when the I C bus is idle. 3.5 0.35 3.0 0.30 2.5 0.25 2.0 Total ICC (µA): Total ICC (µA): In a typical Mobile Internet Device (MID) application, I C data transactions are idle the vast majority of the time. 2 Therefore, it is critical that the I C translator burns as little current as possible when no data transactions are 2 passing across the I C bus.

In short, the more a repeater can sink current while maintaining the maximum VOL, the more capacitance it 2 can drive at a given data rate. The I C specifically benchmarks this by stating: “to drive a full bus load at 400kHz, 6mA IOL is required at 0.6V VOL. Parts not meeting this specification can still function, but not at 400kHz and 400pF”. 2 The question then arises, “What makes a good I C repeater?” The question becomes complicated when considering the following factors: ƒ ƒ ƒ As shown in Figure 6, the FXM2IC102 can typically sink 11mA – 13mA, depending on temperature, while maintaining a VOL of 0.33V when VDD is only 1.65V. This says the FXM2IC102 delivers conservatively twice the current sinking capability for a 400pF, 1.65V segment running at 400kHz. Current sinking capability of the outputs Output edge rates 2 Distributed and lumped capacitances of the I C segment ƒ Speed of the I C bus: standard mode (100kbits/s), fast mode (400kbit/s), or fast-mode plus (1000kbit/s) ƒ ƒ Pull-up resistor sizing ƒ ƒ Multiple master / slave topologies 2 If VDD = 1.95V, (Figure 7) the FXM2IC102 can sink 18mA – 21mA, depending on temperature, while maintaining a VOL of 0.39V. This says the FXM2IC102 delivers conservatively 3 times the current sinking capability for a 400pF, 1.95V segment running at 400kHz. System signal delays, including device propagation delay and time of flight vs. meeting critical data setup/hold times If VDD = 3.0V, the FXM2IC102 can sink 25mA – 30mA, depending on temperature, while maintaining a VOL of 0.4V. This says the FXM2IC102 delivers conservatively 4x the current sinking capability for a 400pF, 3.0V segment running at 400kHz. Clock stretching It is possible to simplify this by focusing on the output current sinking capability relative to the bus impedance. 2 The DC electrical tables of the I C specification, for fast mode, require a maximum VOL of 0.4V while sinking 3mA of current when VDD > 2V, and a maximum VOL of 0.2 * VDD, while sinking 3mA when VDD < 2V.
