In short, the difference between PIC and ATMEL is moretheless the same as the difference between "Pink Lady" and "Granny Smith" ..
The first two are both microprocessors - the second two are both apples ..
8051 and 8052 - no programmer will program chips without program memory ..
And finally, here is a link to programmer which can program t

I m using at89c51/at89s51 to drive the motor
the circuit is like controller generates the PWM on two pins( 50% duty cycle + equal and opposite)
that is fed into a latch and in turn latch drives the transistor + relay circuit
The relay in the response runs the motor in CW/ACW direction depending on PWM signal
my problem is that some

A simple presence of flash memory alterable when the 8951 is supplied only with +5v was strong enough for a good advertisement.
A voltage of +12v was not so common available in the electronic boards based on microcontroller supplied at +5v.
Thus, such a kind of microcontrollers with internal flash memory program, alterable only at +12v, have to b

I have a problem with the at89s51 and at89c51.
Why at89c51 easily damaged if the reprogram continue, while at89s51 safe.
Coz the at89c51 flash memory can be programmed upto 1000 times while the at89s51 can be programmed from 1000-10000 times.

that example is not for a 8051 device... it`s big brother, the 8052 (and likes) actually have 256 Bytes of ram, but just the lower half (00h to 7Fh) can be accessed by direct and indirect addressing and the existing upper half, (80 to FFh) just can be accessed by indirect addressing
Direct addressing will make access to the SFRs...

The issue here is NOT the mechanics or semantics of Synopsys.
There is a major difference between Clock Tree & Reset Tree - in regards to correct design practices.
1. Clock Tree must always be 'Skew Balanced' to avoid synchronous skips & races.
2. Reset Trees - especially for those cases where the Reset is Asynchrounous - MAY not be 'Skew Ba
