Description

The ICM7211 (LCD) and ICM7212 (LED) devices constitute a family of non-multiplexed four-digit seven-segment CMOS display decoder-drivers.

The ICM7211 devices are configured to drive conventional LCD displays by providing a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs.

Features ICM7211 (LCD)

? Four Digit Non-Multiplexed 7 Segment LCD Display Outputs with Backplane Driver

? Complete Onboard RC Oscillator to Generate Backplane Frequency

? Backplane Input/Output Allows Simple Synchronization of Slave-Devices to a Master

? ICM7211 Devices Provide Separate Digit Select Inputs to Accept Multiplexed BCD Input (Pinout and Functionally Compatible with Siliconix DF411)

? ICM7211M Devices Provide Data and Digit Address Latches Controlled by Chip Select Inputs to Provide a Direct High Speed Processor Interface

? ICM7211 Decodes Binary to Hexadecimal; ICM7211A Decodes Binary to Code B (0-9, Dash, E, H, L, P, Blank)

? ICM7211A Available in Surface Mount Package

Features ICM7212AM (LED)

? 28 Current-Limited Segment Outputs Provide 4-Digit Non-Multiplexed Direct LED Drive at >5mA Per Segment

? Brightness Input Allows Direct Control of LED Segment Current with a Single Potentiometer or Digitally as a Display Enable

? ICM7212AM Device Provides Same Input Configuration and Output Decoding Options as the ICM7211AM
