In-System FLASH Programming with hardware
implemented bank switching capability
The following information concerns all microcontrollers of the C5xx / SAB 80C5xx family
which use an internal ROM mask in combination with an external code FLASH memory.
The external FLASH memory can be used as reprogrammable code memory for the
application software. This application focuses on SIEMENS 8-bit microcontroller
derivatives with internal code memory (ROM) sizes of 8/16 Kbyte in maximum because
of the overlapped code memory area of the FLASH memory of 8/16 Kbyte cannot be
used:
C501-1R
C502-2R
C504-2R
C511(A)-R
C513(A)-R/-2R
C515-1R
SAB 80C535
SAB 80C537
This application note describes the proceeding for the in-system reprogramming of
application software by using special application hardware for memory bank switching and
software programming service routines in the internal mask programmable ROM for
external FLASH memories (5V-only).
Due to the ′Harvard Architecture′ (separate code memory and data memory areas)
erasing and writing of the FLASH memory only can be done when mapping it in the
corresponding data memory area. This will be achieved by using a port pin as a software
switch which distinguishes between ′Normal Mode′ and ′Programming Mode′ in
combination with a PLD (Programmable Logic Device).
