Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM6502B/6512 is a low-power, 4-bit microcontroller implemented in complementary
metal-oxide semiconductor technology.
The device is ideally suited to battery-powered systems such as watches and game machines
because it can directly drive LCDs with up to 108 picture elements.
