Overview

This document provides essential corrections and technical updates for the MC68340 Integrated Processor with DMA. Key revisions include corrected timing diagrams for the negation of HALT and BERR signals during Retry and Late Retry sequences, and a typo correction in the Channel Status Register description regarding error status bits. It details updated pin assignments and case dimensions for the 144-lead Thin Quad Flat Pack (PV suffix) and introduces the Plastic Quad Flat Pack (FT suffix) specifications. Comprehensive ordering tables for 5.0V and 3.3V versions are provided, covering frequencies from 8.39MHz to 25MHz in FE, RP, and PV package types. Additionally, the document specifies VCC and GND pin groupings for electrical isolation of output drivers.
