The 3V to 10V supply range is the headline decision point. At 3.3V nominal the part is fully operational, but check the LCD contrast voltage — the driver's output swing tracks VDD, so a 3.3V rail yields a 3.3V segment drive. If your display needs a higher contrast voltage (common in larger or high-temperature LCDs), you may need to run the driver from a boosted supply within the 10V ceiling. Industrial temperature rating (-40°C to 85°C) means the part is specified for outdoor, unheated, or engine-adjacent enclosures. No derating needed for cold-start or hot-day operation within that range. Note that the part is RoHS non-compliant, so it is not suitable for new European-market consumer products or any assembly requiring RoHS exemption-free status. For repair or legacy builds where leaded solder is acceptable, this is not a blocker.","metaTitle":"National Semiconductor MM5452V LCD Driver, 4.5 Digits","metaDescription":"National Semiconductor MM5452V COPS™ LCD driver: 3V-10V supply, 32-segment, 4.5 digits, -40°C to 85°C, 44-PLCC.

The LCD segment drive voltage will equal the supply, so contrast may be lower than with a 5V rail."},{"question":"What microcontroller interfaces with MM5452V?","answer":"The MM5452V uses a serial data interface, so any microcontroller with a spare serial output (GPIO bit-banged or SPI) can drive it. No special peripheral is required."},{"question":"Does MM5452V replace MM5452N in existing designs?","answer":"The MM5452V is the surface-mount 44-PLCC variant of the same driver. The MM5452N is the through-hole DIP version. Functionally identical, but the footprint and mounting are different — verify the PCB layout before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MM5452V","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MM5452V when reusing this data.
