Each device is available for production in user programmable versions (Flash) as well as in factory coded
versions (ROM/FASTROM).
ST7232A-Auto are ROM versions. ST72P32A-Auto devices are factory advanced service technique
ROM (FASTROM) versions: they are factory-programmed HDFlash devices.
Flash devices are shipped to customers with a default content (FFh), while ROM factory coded parts
contain the code supplied by the customer. This implies that Flash devices have to be configured by the
customer using the option bytes while the ROM devices are factory-configured.

1. Depends on device type as defined in
The option bytes allows the hardware configuration of the microcontroller to be selected. They have no
address in the memory map and can be accessed only in programming mode (for example using a
standard ST7 programming tool). The default content of the Flash is fixed to FFh. To program directly the
Flash devices using ICP, Flash devices are shipped to customers with an internal clock source selected.
In masked ROM devices, the option bytes are fixed in hardware by the ROM code (see option list).
