1. Outline The PCA7755D is a converter board from 64-pin QFP (64P6U) to standard-pitch (2.54-mm). The pins correspond one-to-one. 2. Connecting the Oscillator Circuit Pattern Take notice that the processing depends on whether or not the IC1 (oscillator module) is used. (1) When the IC1 (oscillator module) is used Recommended oscillator module: SG-51P (Seiko Epson Corporation) When using the IC1, the following processing is necessary (see (1) to (3) in Figure 1). (1) Supply VCC

(2) When using 2-pin type oscillator When using a 2-pin type oscillator, follow the procedure below (see (1) to (8) in Figure 3). For the capacitor capacity and the resistance value, contact the capacitor distributor. (1) Install an oscillator at the XTAL1. (2) Install a capacitor at the C2. (3) Install a capacitor at the C3b. (4) Install a resistor at the Rd. (5) Install a resistor at the Rf. (6) Connect the XIN pin. (7) Connect the XOUT pin. (8) Connect the GND of the oscillator.
