DESCRIPTION
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.
