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
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/ I
into any system quickly and easily using Zilog’ s solution.
