1. Overview
The S5U1C6F632T1/T2 (SVT6F632: Software eValuation Tool for S1C6F632) are evaluation boards for the S1C6F632 single-chip
microcomputer made by Seiko Epson. These boards feature a circuit structure designed for the Weather Center, which is an example
of one of S1C6F632’s applications. The S1C6F632’s internal circuit functions can drive a 48 seg. x 32 com LCD, measure
temperature and humidity, and produce a buzzer output. Equipped with an external pressure sensor and an illumination sensor, the
S5U1C6F632T1/T2 boards provide power-saving control based on weather forecasts and illumination intensity.
The SVT6F632 comes with two types of boards: S5U1C6F632T1 and S5U1C6F632T2. The S5U1C6F632T1 is capable of
standalone operations, while the S5U1C6F632T2 can connect to the In-Circuit Emulator (ICE63: S5U1C63000H) for software
debugging. Each board is provided with an expansion connector to allow clients to connect custom boards.
