General Description
The ZLR32300 is an MROM-based member of the
Crimzon MCU family of infrared microcontrollers.
With 237 bytes of general-purpose RAM and up to
32KB of MROM, ZiLOG’s CMOS microcontrol-
lers offer fast executing, efficient use of memory,
sophisticated interrupts, input/output bit manipula-
tion capabilities, automated pulse generation/
reception, and internal pull-up transistors. This
device is compatible with ZLP32300 OTP devices.
