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.

Crimzon ZLF645 Flash MCU Detailed Feature Set
z8® lxmc cpu core
The Z8 LXMC CPU is an enhanced version of the Z8 CPU, with the following features:
Program/constant memory with 64/128 pages of 512 bytes each (total 32/64 KB Flash memory)
Up to 4 KB of register file address space (512 B/1 KB is implemented in ZLF645)
Direct register-to-register architecture allows fast data
Code compatible with other Crimzon / Z8 MCUs
Software stack can be allocated in 1 K linear RAM, which allows much greater depth in subroutine calls
and interrupt nesting than a hardware stack
C-compiler support
flash controller
The Crimzon ZLF645 family of devices can address up to 64 KB of Flash memory. The Flash controller pro-
vides the appropriate Flash controls and timing for byte programming, Page Erase, and Mass Erase. Reading
of the Flash memory for Flash accesses is made by either the CPU or through the In-Circuit Programming
(ICP) interface. The Flash controller contains protection mechanisms to prevent accidental programming or
erasure. It also has the read protection for maximum code security. The Flash option bits provide additional
customization in input port pull up, 16-bit stack pointer, oscillation filter, etc.
The In-Circuit Programming (ICP) interface is a single pin RS-232 like interface for programming, reads, and
memory erasures to the Crimzon ZLF645’s Flash memory. Zilog’s USB Smart Cable can be used across dif-
ferent Zilog Flash MCUs.
infrared learning amplifier & learning algorithm
The Crimzon ZLF645 Flash MCU’s infrared learning amplifier can detect and decode infrared transmissions
directly from the output of an infrared photodiode without the need for external circuitry. The MCU also has
an integrated digital timer that allows it to filter out the carrier signal while capturing the envelope signal.
This capability eliminates external components for the filter, automatic gain control, and the amplifier, thereby
greatly simplifying your design, increasing reliability and lowering your cost.
The Zilog learning algorithm has been characterized with all popular infrared signals to ensure excellent
performance. In addition, Zilog’s tuned IR amplifier can support a wide range of distance between the OEM
remote to the learning remote. Our expertise creates a real user-friendly learning remote application.
uart
The Universal Asynchronous Receiver/Transmitter (UART) is a full-duplex communication channel capable
of handling asynchronous data transfers. The UART uses a single 8-bit data mode with selectable parity. This
communication interface is well suited for Master/Slave system communications and factory diagnostics.
Zilog also provides a complete Application Program Interface (API) to the user. Using the API, it is very simple
to send UART/ I2C commands to the Crimzon RC Blaster. The complete remote functions can be integrated
into any system quickly and easily using Zilog’s solution.
