The XL7221 from Xinluda is a compact serial input/output, common-cathode LED display driver that connects a microprocessor to a 7-segment numeric LED display of up to 8 digits, a bar-graph display, or up to 64 individual LEDs. It is designed as a drop-in, MAX7221-compatible device, making it a practical second source for legacy and cost-sensitive display designs.
Each XL7221 integrates a BCD Code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8×8 static RAM that stores each digit’s data. Only a single external resistor is required to set the segment current for all LEDs, and the device offers both per-digit decode selection and dual (digital and analog) brightness control. Its slew-rate-limited segment drivers help reduce electromagnetic interference (EMI), and a low-power shutdown mode retains display data.
The XL7221 is a specialty display-driver IC with little to no authorized-distributor stock, which can stall production and repair builds. Pacific Component Xchange specializes in hard-to-find and obsolete power-management and interface ICs, helping engineers and buyers secure parts that mainstream catalog distributors cannot supply. We back our sourcing with authenticity verification and global shipping. Request a quote (RFQ) for the XL7221 today and our team will source genuine product to meet your quantity, lead-time, and quality requirements.
The XL7221 is a serially interfaced, 8-digit common-cathode LED display driver from Xinluda. It connects a microprocessor to up to 8 seven-segment digits, a bar-graph display, or up to 64 individual LEDs through a simple serial interface.
Yes. The XL7221 is designed to be function- and pin-compatible with the industry-standard Maxim/Analog Devices MAX7221, making it a practical second source for existing display designs.
The XL7221 is supplied in a 24-pin SOP-24 (300mil) surface-mount package. A through-hole DIP-24 version is offered by Xinluda under the part number XD7221.
The XL7221 uses a 10MHz serial interface that is compatible with SPI, QSPI, and Microwire, allowing straightforward connection to most microcontrollers.
The XL7221 is a specialty display-driver IC with limited authorized-distributor availability. Pacific Component Xchange sources it on a request-for-quote basis so we can confirm genuine stock, quantity, and lead time for your specific order.
