1. Outline

The PCA7757 is a converter board from 64-pin FLGA (64F0G) 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 and GND.
(2) Connect the OUT pin to the XIN pin.
(3) Install a bypass capacitor at the C1.
