Device specific information

1.1

Flash technology types

Three Flash technologies are available in the ST7 family with different programming

methods. Each ST7 Flash microcontroller is associated with one of these three technologies

as shown in Table 1: ST7 Flash microcontroller types.

●

XFlash (Extended): Flash memory based on a EEPROM technology

●

HDFlash (High Density): Flash memory based on Flash technology

●

CFlash (ST72Cxxx): Flash memory based on a EEPROM technology (see AN1179 for

more details)

For further information on XFlash and HDFlash, refer to the Flash programming reference

manual.

RC calibration value addresses

Table 2 holds the addresses of the RC calibration values in the event of removal of readout

protection. The full procedure of restoring RC calibration values is described in the Flash

programming reference manual. This procedure applies only to the devices listed in the

following table. For the other devices, the RC calibration values are not lost if the readout

protection is removed.
