1 / 8 page 1 ® ICM7211AM 4-Digit, LCD Display Driver The ICM7211AM device is a non-multiplexed four-digit seven-segment CMOS LCD display decoder-driver. This device is configured to drive conventional LCD displays by providing a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs. It also has a microprocessor compatible input configuration, which provides data input latches and Digit Address latches under control of high-speed Chip Select inputs. These devices simplify the task of implementing a cost-effective alphanumeric seven-segment display for microprocessor systems, without requiring extensive ROM or CPU time for decoding and display updating. The ICM7211AM provides the “Code B” output code, i.e., 0-9, dash, E, H, L, P, blank, but will correctly decode true BCD to seven-segment decimal outputs. Features • 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 • Provides Data and Digit Address Latches Controlled by Chip Select Inputs to Provide a Direct High Speed Processor Interface • Decodes Binary to Code B (0-9, Dash, E, H, L, P, Blank) • Pb-Free Plus Anneal Available (RoHS Compliant) Ordering Information PART NUMBER PART MARKING DISPLAY TYPE DISPLAY DECODING INPUT INTERFACING DISPLAY DRIVE TYPE TEMP.

Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. *Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications. CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
