Flash Memory (HFM)
20.1 Overview
The embedded flash memory module is a nonvolatile memory module that operates with
the program and IP buses.
The programming voltage required to program and erase the flash memory is generated
internally by charge pumps. Program and erase operations are performed by a command-
driven interface from the DSC core using an internal state machine. It is not possible to
read or fetch from a block while it is being programmed or erased.
20.1.1 Features
Freescale Semiconductor
• Up to 64 KB (32K words) of program flash memory
• 60 MHz (word access) operation for all flash access.
• Automated program and erase operation
• Interrupts on command completion, command buffer empty and access error.
• Fast page erase capability to erase only 2 KB
• Security feature to prevent unauthorized reads of flash contents
• Programmable sector protection feature to protect flash from being erased and
• The flash memory supports byte and word read operations by the DSC core
• Code integrity check using built-in data signature calculation
• In-application programming and in-circuit programming capabilities
programmed unexpectedly
