q Core CPU Architecture
q SVD Circuit / Comparator
q Super Low Operating Voltage (0.9V)
q High Quality Display LCD Driver
s DESCRIPTION
The E0C6S37 is an advanced single-chip CMOS 4-bit microcomputer consisting of the E0C6200A CMOS 4-bit
core CPU. It also contains the ROM, RAM, LCD driver circuit, time base counter and stopwatch counter. The
E0C6S37 provides an excellent solution for low-power consumption systems with clock functions.
