ICM7218
ICM7218 is 8-Digit LED Microprocessor-Compatible Multiplexed Display Decoder Driver manufactured by Renesas.
feature two control lines (WRITE and MODE) which write either 4 bits of control information (DATA ING, SHUTDOWN, DECODE and HEXA/CODE B) or 8 bits of display input data. Display data is automatically sequenced into the 8-byte internal memory on successive positive going WRITE pulses. Data may be displayed either directly or decoded in Hexadecimal or Code B formats. The ICM7218C and l CM7218D feature two control lines (WRITE and HEXA/CODE B/SHUTDOWN), 4 separate display data input lines, and 3 digit address lines. Display data is written into the internal memory by setting up a digit address and strobing the WRITE line low. Only Hexadecimal and Code B formats are available for display outputs. Features - Microprocessor patible - Total circuit integration on-chip includes: - Digit and segment drivers - All multiplex scan circuitry - 8-Byte static display memory - 7-Segment Hexadecimal and Code B decoders - Output drive suitable for LED displays directly - mon anode and mon cathode versions - Single 5V supply required - Data retention to 2V Supply - Shutdown feature - turns off display and puts chip into low power dissipation mode - Sequential and random access versions - Decimal point drive on each digit Related Literature - Technical Brief TB363, “Guidelines for Handling and Processing Moisture Sensitive Surface Mount Devices (SMDs)” ID0-ID7 INPUT DATA ICM7218A MON ANODE ICM7218B MON CATHODE ID4-ID7 MODE WRITE 8 CONTROL INPUTS DECODE CONTROL SHUTDOWN HEXA/CODE B LOGIC 8-BYTE WRITE ADDRESS STATIC...
