Features
Key features of Zilog’s ZLP32300 OTP MCU
include:
•2.0–3.6 V operation
•Low-power consumption—6 mW (typical)
•Three standby modes:
–STOP—2 µA (typical)
–HALT—0.8 mA (typical)
–Low-voltage reset
•Special architecture to automate generation
and reception of complex pulses or signals:

with two capture registers and two load
registers
–One programmable 16-bit counter/timer
with one capture register and two reload
registers
–Programmable input glitch filter for pulse
reception
•Six priority interrupts:
–Three external
–Two assigned to counter/timers
–One low-voltage detection interrupt
•Low-voltage and high-voltage detection flags
•Programmable Watchdog Timer (WDT)
•Power-on reset (POR) circuits
•Two independent comparators with
programmable interrupt polarity
•Programmable EPROM options:
–Port 0: 0–3 pull-up transistors
–Port 0: 4–7 pull-up transistors
–Port 1: 0–3 pull-up transistors
–Port 1: 4–7 pull-up transistors
–Port 2: 0–7 pull-up transistors
–EPROM protection
–WDT enabled at POR
General Description
The ZLP32300 MCU is an OTP-based member of
the Crimzon MCU family of infrared microcontrol-
lers. With 237 B of general-purpose RAM and up to
32 KB of OTP, Zilog’s CMOS microcontrollers
offer fast executing, efficient use of memory, sophis-
ticated interrupts, input/output bit manipulation
capabilities, automated pulse generation/reception,
and internal pull-up transistors. Compatible with
ZLR16300 and ZLR32300 mask ROM families.
