mpc533/mpc534產品簡介

　　This document provides an overview of the MPC533/MPC534 microcontroller， including a block diagram showing the major modular components， sections that list the major features， and differences between the MPC533 and the MPC555. The MPC533 and MPC534 devices are members of the Motorola MPC500 RISC Microcontroller family. The parts herein will be referred to only as MPC533 unless specific parts need to be referenced.

　　The MPC533 device offers the following features： ? 32-bit single issue PowerPC? core ? Unified system integration unit （USIU） with a flexible memory controller and enhanced interrupt controller （EIC） ? 64-bit floating-point unit （FPU） ? 512-Kbytes of Flash EEPROM memory — Typical endurance of 100，000 write/erase cycles @ 25oC — Typical data retention of 100 years @ 25oC ? 32-Kbytes of static RAM in one CALRAM module， configured as — 28-Kbyte normal access only array — 4-Kbyte normal access or overlay access array （eight 512-byte regions） ? One 22-timer channel modular I/O system （MIOS14） ? One TouCAN module （TouCAN B） ? Enhanced queued analog system （QADC64E） ? One queued serial multi-channel module （QSMCM）， which contains one queued serial peripheral interface （QSPI） and two serial controller interfaces （SCI/UART） ? One peripheral pin multiplexing module （PPM） with a parallel to serial driver
