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 a complete RC oscillator, divider chain, backplane driver, and 28 segment outputs to drive LCD displays directly. The device provides 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 features a maximum clock frequency of 16 kHz. Power consumption is low, with a maximum supply current of 10 uA and power dissipation of 500 mW. It 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 onboard RC oscillator and divider chain to generate backplane frequency without external components
• Provides direct high-speed processor interface via 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

Display Drivers Applications

• Four-digit non-multiplexed LCD display systems
• Microprocessor-based instrumentation requiring direct decoding
• Digital readout devices utilizing seven-segment LCDs

Display Drivers Procurement Notes

Verify the specific suffix 'AMIPL+' against official datasheets to confirm lead-free status and RoHS compliance, as generic part numbers may vary. Confirm package type is PDIP-40 and check for availability constraints, as some distributors indicate limited regional sales or discontinuation status for certain variants. Ensure the intended application matches the specified -20°C to +85°C temperature range.

Display Drivers Selection Notes

Select this component when a non-multiplexed solution for four-digit seven-segment LCDs is required. It is suitable for designs needing integrated timing generation and direct microprocessor interfacing. Consider the 3V to 6V supply requirement and 10 uA current consumption for battery-powered applications. Verify that the 40-pin PDIP package fits the PCB layout constraints compared to other available packages like MQFP.

Display Drivers Part Context

The ICM7211 series belongs to the family of LCD display drivers from Maxim Integrated (now Analog Devices). These devices are designed to simplify the interface between digital logic and LCD panels by combining decoding, driving, and timing functions. The ICM7211 specifically targets four-digit applications, distinguishing it from multi-digit multiplexed drivers like the ICM7218.

Display Drivers Replacement Considerations

Direct substitutes include the ICM7211AMlPLZ (Pb-free version) and the ICM7211AMlM44 (MQFP package variant). Verify pin compatibility and electrical specifications before substitution.
