хотя.. ответ дан в даташите: Appendix A: Migrating from dsPIC33FJXXXMCX06/X08/X10 Devices to dsPIC33FJXXXMCX06A/X08A/X10A Devices . 

The dsPIC33FJXXXMCX06A/X08A/X10A devices were designed to enhance the dsPIC33FJXXXMCX06/ X08/X10 families of devices.

In general, the dsPIC33FJXXXMCX06A/X08A/X10A devices are backward-compatible with dsPIC33FJXXXMCX06/X08/X10 devices; however, manufacturing differences may cause dsPIC33FJXXXMCX06A/X08A/X10A devices to behave differently from dsPIC33FJXXXMCX06/X08/X10 devices.

Therefore, complete system test and characterization is recommended if dsPIC33FJXXXMCX06A/X08A/X10A devices are used to replace dsPIC33FJXXXMCX06/X08/X10 devices.

The following enhancements were introduced:

• Extended temperature support of up to +125ºC

• Enhanced Flash module with higher endurance and retention

• New PLL Lock Enable Configuration bit

• Added Timer5 trigger for ADC1 and Timer3 trigger for ADC2
