GENERAL DESCRIPTION
The PCD3745A is a microcontroller oriented towards
communication and metering applications. It has
4.5 kbytes of One Time Programmable (OTP) memory,
224 bytes RAM and 16 I/O lines.
The PCD3745A also incorporates a low power Real-Time
Clock (RTC) and two low power 16-bit counters. The RTC
runs using a 32 kHz crystal oscillator and is register
adjustable. The RTC and the counters are able to operate
in all microcontroller modes. The instruction set is based
on that of the MAB8048 and is software compatible with
the PCD33xxA family.
This data sheet details the specific properties of the
PCD3745A. The shared characteristics of the PCD33xxA
family of microcontrollers are described in the “Data
Handbook IC14; Section PCD33xxA Family” which should
be read in conjunction with this publication.
