128 KByte Flash Module (S12XFTM128K2V1)
24.1
Introduction
The FTM128K2 module implements the following:
•
128 Kbytes of P-Flash (Program Flash) memory, consisting of 2 physical Flash blocks, intended
primarily for nonvolatile code storage
•
32 Kbytes of D-Flash (Data Flash) memory, consisting of 1 physical Flash block, that can be used
as nonvolatile storage to support the built-in hardware scheme for emulated EEPROM, as basic
Flash memory primarily intended for nonvolatile data storage, or as a combination of both
•
2 Kbytes of buffer RAM, consisting of 1 physical RAM block, that can be used as emulated
EEPROM using a built-in hardware scheme, as basic RAM, or as a combination of both
The Flash memory is ideal for single-supply applications allowing for field reprogramming without
requiring external high voltage sources for program or erase operations. The Flash module includes a
memory controller that executes commands to modify Flash memory contents or configure module
resources for emulated EEPROM operation. The user interface to the memory controller consists of the
indexed Flash Common Command Object (FCCOB) register which is written to with the command, global
address, data, and any required command parameters. The memory controller must complete the execution
of a command before the FCCOB register can be written to with a new command.
