ZLR64400 ROM MCU
Product Specification

Architectural Overview
The ZLR64400 ROM MCU is a member of the Crimzon family of infrared microcon-
trollers. It provides a directly-compatible code upgrade path to other Crimzon MCUs,
offers a robust learning function, and features up to 64KB read only memory (ROM) and
1004 bytes of general-purpose random-access memory (RAM). Two timers allow the gen-
eration of complex signals while performing other counting operations. A UART allows
the ZLR64400 MCU to be a slave/master database chip. When the UART is not in use, the
Baud Rate Generator can be used as a third timer. Enhanced Stop-mode recovery (SMR)
features allow the ZLR64400 MCU to awaken from STOP mode on any change of logic,
and on any combination of the 12 SMR inputs. The SMR source can also be used as an
interrupt source.
Many high-end remote control units offer a learning function. Simply stated, a learning
function allows a replacement remote unit to learn most infrared signals from the original
remote unit and regenerate the signal. However, the amplifying circuits of many learning
remotes are expensive, are not tuned well, and result in frustrated users. ZiLOGs
ZLR64400 MCU is the first chip dedicated to solving this problem because it offers a
built-in tuned amplification circuit in a wide range of positions and battery voltages. The
only external component required is a photodiode.
The ZLR64400 MCU greatly reduces system cost, yet improves learning function reliabil-
ity. Best of all, however, will be the user experience promised by ZiLOGs superior learn-
ing function. With all new features, the ZLR64400 MCU is excellent for infrared remote
control and other MCU applications.
