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
