ZLF645 Crimzon Flash Microcontroller with ZBase Database
Industry Leading Universal Infrared Remote Control (UIR) Solution
Overview
The Crimzon ZLF645 Flash Microcontroller with ZBase database is the latest industry leading universal
remote control solution in Zilog’s popular UIR product line. The ZLF645 Flash MCU incorporates Flash
technology for greater supply chain flexibility and faster time-to-market. With the Crimzon ZLF645 Flash
Microcontroller, the program code and Zilog’s ZBase database, the industry-leading infrared database, can be
programmed into the Flash memory at the final manufacturing stage.
The Crimzon ZLF645 Flash microcontroller also offers exceptional Bill of Material (BOM) costs savings. With
up to 64 KB of Flash, the Crimzon ZLF645 MCU can be used to store the user programmed data, learning
infrared signal timing and the infrared database eliminating the need for external EEPROM. For learning
remote applications, the Crimzon ZLF645 Flash MCU has an integrated tuned IR amplifier with a learning
distance range of 0 to 8 inches, a significant increase over other solutions on the market that typically work
in a small 0 to 3 inch range. Additionally, our integrated tuned IR amplifier eliminates the need for an external
signal filter, amplifier, and automatic-gain-control circuit, further reducing the overall BOM cost.
Zilog’s ZBase database is a complete IR database with comprehensive brand and model coverage based on
Point-of-Sale (POS) data for most all consumer electronic equipment. Independent third party field tests show
that Zilog’s ZBase database outperforms the competition in brand and model coverage. The use of POS data
allows us to scientifically articulate our market coverage. ZBase database coverage includes thousands of
codes for devices such as TVs, DVRs, DVDs and cable/satellite boxes. And, unlike other databases in the
market, Zilog captures codes directly from OEM remote controls. Our Zero Defect policy ensures precise cap-
ture of the OEM remote, resulting in the highest quality database available in the market today. The benefits
to our customers are lower call center volume, lower return rate, and more satisfied consumers.
Zilog’s Crimzon ZLF645 Flash Microcontroller with ZBase database is a complete universal remote control
solution that decreases system BOM cost, minimizes inventory management costs, and delivers the highest
quality database coverage.
