Datasheet
LED DRIVER IC OF(12~11) x(6~7)SEGMENTS DISPLAY
DESCRIPTION
Eleven segment output lines, six grid output lines, 1 segment/grid
output lines, one display memory, control circuit, key scan circuit are
all incorporated into a single chip to build a highly reliable peripheral
device for a single chip microcomputer. Serial data is fed to SC16461
via a four-line serial interface. Housed in a 32-pin SOP package,
SC16461 pin assignments and application circuit are optimized for
easy PCB layout and cost saving advantages.
