DESCRIPTION

TM1628 is an LED Controller driven on a 1/7 to 1/8 duty factor. 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 TM1628 via a three-line serial interface.

Housed in a 28-pin SO Package, TM1628 pin assignments and application

circuit are optimized for easy PCB Layout and cost saving advantages.
