Overview
The ICM7243BIPLZ is an 8-character, microprocessor-compatible LED display decoder driver manufactured by Renesas Electronics Corporation. It integrates a 64-character ASCII decoder, 8x6 static memory, high-power character and segment drivers, and multiplex scan circuitry on a single chip. Designed for direct interfacing with common cathode LED displays, it supports both 14-segment and 16-segment fonts including decimal points. The device operates on a single +5V supply and features a standby mode for low power consumption.
Feature Summary
- Integrates 64-character ASCII decoder and 8x6 static memory for efficient data handling
- Directly drives common cathode LED displays with high-power segment and character drivers
- Supports mask-programmable font sets beyond standard ASCII characters
- Features cascading capability without additional hardware for multi-display systems
Applications
- Microprocessor-based alphanumeric display systems
- Digital instrumentation requiring 14-segment or 16-segment LED readouts
- Industrial control panels with multiple display characters
- Consumer electronics utilizing common cathode LED indicators
Procurement Notes
Verify the specific suffix 'BIPLZ' against the manufacturer's current datasheet to confirm package type (PDIP-40) and RoHS compliance status. Ensure the ordering code matches the exact temperature range and material specifications required for your design. Cross-reference with official Renesas documentation to avoid confusion with similar variants like ICM7243BIPL or ICM7243AIPLZ.
Selection Notes
Select this component when an integrated solution for driving 8-character alphanumeric LED displays is required. It eliminates the need for external decoders and memory chips. Consider its microprocessor compatibility and sequential/random entry modes for system integration. Verify that the target application utilizes common cathode LED displays compatible with the device's drive capabilities.
Part Context
The ICM7243 series belongs to Renesas' family of specialty logic circuits designed for display applications. Variants such as ICM7243BKIT and ICM7243BLPL share core functionalities but may differ in packaging or testing configurations. This part specifically denotes a lead-free, PDIP-40 packaged version within the broader ICM7243 product line.
Replacement Considerations
Public confirmed substitute part numbers include ICM7243BIPL and ICM7243AIPLZ. Verify pinout compatibility and electrical characteristics before substitution. Ensure the alternative variant supports the same 14/16-segment font requirements and microprocessor interface protocols.
