8051 microcontrollers

Phyton has been delivering highest quality with the PICE-51 in-circuit emulators for over five years. Even though our customers' feedback has been very positive, we are constantly looking for ways to improve our product. We have recently announced a new PICE-52 model that provides all major functions of the old model yet supports many more 8051 derivatives, thus offering developers more features for the same price.

However, a few 8051 derivatives from Dallas Semiconductor and Philips are supported by PICE-51 only. Please be sure to check if PICE-52 supports your target; if it does not, repeat search in the PICE-51 data base. Please do not hesitate to call us if you need our assistance.

PICE-52 and PICE-51 - what is similar and what is different in the tools?

Major features PICE-51 (old) PICE-52 (new) Differences Enhanced Hook emulation of the Atmel 8xC51Rx2, CC01/02/03, 8xC511x, others.
