No, you can erase only the whole chip.
The only way to modify a part of the content is to read the whole content into a temporary storage (I'd use an external serial eeprom e.g. 24Cxx, if there is not enough internal storage onchip of the PIC); perform the erase, and then write back the...
simple question..!!
The manufacturer tells us in their full color brochures ;-)
Seriously: it's the width of the data bus; most arithmetic operations, data moves etc. work on this number of bits.

p89c51rd2 isp
On of the high points of '89C51RD2 and family is the built-in serial bootloader. It means, you don't neead ANY programmer, as long as the board with the 'RD2 has an RS232 level converter (such as MAX232) connected to Rx and Tx pins of the mcu; then a simple serial cable (or an...
8051 timer problem
Although unlikely, in some very rare applications it might be viable to use the timer serving as a baudrate generator also as a timer, simply enabling its interrupt (and reducing most of the interrupts to a mere djnz SlowDownCounter,xxx; xxx: reti); although if baudrate is...
Performance of ....
"Performance" (whatever that might mean) of ANY integrated circuit heavily depends also on its surrounding circuitry and enclosure. There are certainly parameters such as latch-up immunity and expected lifetime/reliability, given by design and manufacturing process of the...
89s8253 replace
The 8253 had quite a lot of hardware issues - it took Atmel several versions of silicon to get it right. Look at the erratas available on Atmel's site and make sure you purchase the newest version of silicon.
