... and surely for all practical purposes, today, "ISP" relates to the serially ("few-pin") programmable chips.
However, where's the line? If you'd not insist on a particular number of pins to be given up for the programming, these chips CAN be programmed e.g. from an LPT port of PC, with zero additional parts (except for a few resistors for line termination) (IIRC, Atmel made a 5V-only version of the AT89C's, too, eliminating the need for the 12V switch). It eats up most of the pins, surely, but is not impossible. JW |

| Go for AT89S52 | 01/01/70 00:00 | |
| I would not say this so definitively... | 01/01/70 00:00 | |
| well 'ISP chip' or 'ISP board' | 01/01/70 00:00 | |
