Driver
The MC144898 is a flexible light-emitting-diode driver which directly in-
terfaces to individual lamps, 7-segment displays, or various combinations of
both. LEOs wired with common cathodes are driven in a multiplexed-by-5
fashion. Communication with an MCUIMPU is established through a synchro-
nous serial port. The MC 144898 features data retention plus decode and scan
circuitry, thus relieving processor overhead. A single, current-setting resistor
is the only ancillary component required.
A single device can drive anyone of the following: a 5-digit display plus
decimals, a 4-112-digit display plus decimals and sign, or 25 lamps. A special
technique allows driving 5 112 digits; see Figure 16. A configuration register
allows the drive capability to be partitioned off to suit many additional applica-
tions. The on-chip decoder outputs 7-segment-format numerals Oto 9, hexa-
decimal characters A to F, plus 151etters and symbols.
The MC144898 is compatible with the Motorola SPI and National MI-
CRO-WIRETM serial data ports. The chip's patented 8itGrabberTM registers
augment the serial interface by allowing random access without steering or
address bits. A 24-bit transfer updates the display register. Changing the con-
figuration register requires an 8-bit transfer.
.Operating Voltage Range of Drive Circuitry: 4.5 to 5.5 V
.Operating Junction Temperature Range: -40° to 130°C
.Current Sources Controlled by Single Resistor Provide Anode Drive
.Low-Resistance FET Switches Provide Direct Common Cathode Interface
.Low-Power Mode (Extinguishes the LEDs) and Brightness Controlled via
Serial Port
.Special Circuitry Minimizes EMI when Display is Driven and Eliminates EMI
in Low-Power Mode
.Power-On Reset (POR) Blanks the Display on Power-Up, Independent of
Supply Ramp Up Time
.May Be Used with Double-Heterojunction LEDs for Optimum Efficiency
.Chip Complexity: 4300 Elements (FETs, Resistors, Capacitors, etc.)
