Note
IMPORTANT: STM8S 8-bit MCU with 8KByte Flash and 640Byte EEPROM. EEPROM is mapped to Data Pattern addresses 4000h-427Fh. Option bytes are mapped to Data Pattern addresses 4800h-483Fh. Flash is mapped to Data Pattern addresses 8000h-9FFFh. ROP byte are ignored during program and verify operation. Select SECURE operation to program AAh to ROP byte which enables read protection. For a read protected device Erase operation clears Read-Out protection and erases all memory. For device that is not read protected Erase operation will only erase Option Bytes and Flash Memory. EEPROM contents remain in their previous state. Option bytes contain configurations for device hardware features and memory protection for the device. Programming invalid data to Option bytes area can cause programming failure.
BPM does not sell programmable devices, nor do we program devices directly. BPM makes programmers and accessories to make programming in-house fast, easy, and profitable.
