Download Speed

Flasher STM8 has been designed to download to the target as fast as possible while still providing the best compatibility and convenience in behavior of the software across all STM8 devices. The table below shows the measured download speed for standalone programming and for programming via PC driven software.

The following environment has been used:

PC with 2.53 GHz Core2Duo, running WinXP
USB 2.0 port
USB 2.0 hub
STM8S208MBT6B

OperationStandalone modePC mode
Program (128KB)8.5s (15KB/s) 8.5s (15KB/s)
Program and verify (128KB)11.3s 11.3s

For compatibility and convenience reasons the standard block programming mode with self-erase is used. As STM8 devices do not provide a mass erase command, a block by block erase of the CPU is required for a full chip erase (please note that removing the Read-Out-Protection for this case might cause side effects in some STM8 devices and is therefore not a suitable replacement for a proper mass erase command). If not required for a specific case like unlocking/erasing the CPU, the normal block programming mode with self-erase provides the better performance and is therefore used.
