DESCRIPTION
The E0C6S32 is an advanced single-chip CMOS 4-bit microcomputer consisting of the E0C6200A 4-bit core
CPU. It also contains the ROM, RAM, LCD driver, event counter, SVD circuit, stopwatch counter, and time base
counter. With wide voltage range and low power consumption, the E0C6S32 provides an excellent solution for
the low-power consumption systems with manganese dry cell.
