MTCH6303 PIN DESCRIPTIONS BOOSTDO RESET • MTCH6303 DO serial data output, connect to MTCH652 DIN Input. • Pulling the RESET pin low generates a device Reset. BOOSTPWM • MTCH652 OSCIN input signal for boost AVDD • Positive supply for analog modules. This pin must be connected at all times. AVSS • Ground reference for analog modules. This pin must be connected at all times. SDA/SCL/IRQ • • • BOOSTOE1/BOOSTOE2 • MTCH652 OE Outputs When OE is set to logic ‘0’, all MTCH652 output latches (OUTxx) are GND. When OE is set to logic ‘1’, all output latches that are set to drive ‘1’ will output the boost voltage level. The MTCH6303 supports up to two MTCH652 devices for larger size screen support. BOOSTLE1/ BOOSTLE2 I2C™ Data I2C Clock I2C Interrupt • MTCH652 LE Outputs Latch Enable Input (LE) is the active-low latch input used for latching-in serial data. Serial data is ignored unless LE is logic ‘0’. After clocking serial data, the data is internally latched when LE changes from logic ‘0’ to logic ‘1’. The MTCH6303 supports up to two MTCH652 devices for larger size screen support. D+/D• USB D+ and D- COMM_SEL • Communication selection pin • VDD: I2C • GND: USB VUSB3V3 • USB internal transceiver supply If the USB module is not used, this pin must be connected to VDD OSC1/OSC2 • Clock signal input VCAP • A low-ESR capacitor is required on the VCAP pin, which is used to stabilize the internal voltage regulator output. The VCAP pin must not be connected to VDD and must have a CEFC capacitor, with at least a 6V rating, connected to ground.
