ICM7211AMIPL+

Display Drivers Overview

The ICM7211AMIPL+ is a non-multiplexed four-digit seven-segment CMOS LCD display decoder-driver manufactured by Analog Devices Inc./Maxim Integrated. It integrates an onboard RC oscillator, divider chain, backplane driver, and 28 segment outputs to drive LCD displays directly. The device features data input latches and digit address latches controlled by chip select inputs for high-speed processor interfacing. It operates within a supply voltage range of 3 V to 6 V and supports a maximum clock frequency of 16 kHz. The component is housed in a 40-pin PDIP package and functions reliably across an operating temperature range of -20°C to +85°C.

Display Drivers Feature Summary

• Integrates complete onboard RC oscillator and divider chain to generate backplane frequency without external timing components
• Provides direct high-speed processor interface through data and digit address latches controlled by chip select inputs
• Includes backplane input/output capability to allow simple synchronization of slave devices to a master system

Display Drivers Applications

• Four-digit non-multiplexed LCD display systems
• Industrial instrumentation with direct microprocessor interfaces
• Consumer electronics requiring low-power LCD decoding

Display Drivers Procurement Notes

Verify the specific suffix 'AMIPL+' against official Analog Devices documentation to confirm lead-free status and RoHS compliance. Confirm current availability as distribution channels may list limited stock or obsolete status. Ensure the 40-pin PDIP package matches the target PCB footprint. Cross-reference the manufacturer part number with the base product ICM7211A to validate functional equivalence before procurement.

Display Drivers Selection Notes

Select this component when a non-multiplexed LCD solution is required to simplify PCB routing and reduce pin count compared to multiplexed alternatives. The integrated oscillator eliminates external timing components, reducing bill of materials cost. Ensure the application requires parallel BCD input and that the 4-digit capacity meets the display requirements. Verify that the 3V to 6V supply range aligns with the system power architecture.

Display Drivers Part Context

The ICM7211 series belongs to the family of CMOS LCD decoder-drivers originally developed by Maxim Integrated, now part of Analog Devices. This specific variant targets applications needing straightforward, non-multiplexed driving for four-digit displays. The PDIP package facilitates through-hole prototyping and assembly. The device serves as a bridge between digital logic and analog LCD segments, handling decoding and driving functions internally.

Display Drivers Replacement Considerations

Direct substitutes include other variants within the ICM7211 family such as ICM7211IQH+TD, though package differences must be accounted for. Verify compatibility with existing firmware and hardware interfaces when switching between different package types or suffixes within the same functional family.
