89SXX series controller | Microcontroller › 8051 › AT89C51 MICROCONTROLLER › 89SXX series controller March 5, 2014 at 5:16 pm #11209 Ashutosh BhattParticipant 89SXX series controller supports SPI programmer. but 89C51 doesnt have SPI. so you can not use that programmer. but if you have 89S51 programmer then why u r not using 89S51? both are pin compitable. you can use them in same circuit without any change.
