Schematic for ATMEL FLIP for 8051 ISP by UART interface

[mafanyau]

Is any body have the schematic for ATMEL FLIP for 8051 ISP by UART interface ?

Attention : FLIP is design for C51 family of processor (such as T89C51RB2/C2/D2. T89C51CC01), it is different with AT89C51.

No special hardware to use FLIP, just use regular RS232 interface.

Actually, there IS a schematics for FLIP on the Atmel's pages - interestingly enough there is no link to it from FLIP's page...

http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3445

Pages 2 and 3 are for the UART connection.

Yes, nothing spectacular there...

PS. budhy is right, this is NOT for AT89C(x0)5x/AT89(x0)S5x. FLIP is for the Temic-legacy higher end '51s - Rx2/Ex2/Ix2 etc.

What's difference of C51 family of processor and AT89C51 processor ? I found the FLIP device selection also support AT89C51xx !

The following device (AT89C51xx) are classified as C51 Family of processor :

AT85C5121, T85C5121 , AT89C5115 , AT89C5121, T89C5121 , AT89C5122 , AT89C5130A-M , AT89C5131 , AT89C5131A-L , AT89C5131A-M , AT89C5132 , AT89C51AC2 , AT89C51AC3 , AT89C51CC01, T89C51CC01 , AT89C51CC02, T89C51CC02 , AT89C51CC03 , AT89C51ED2 , AT89C51IC2 , AT89C51ID2 , AT89C51RB2 , AT89C51RC2 , AT89C51RD2 , AT89C51RE2 , AT89C51SND1C , AT89C51SND2C , T89C51RB2 , T89C51RC2 , T89C51RD2

which have :
* Large Flash memory >= 16 K (16K; 32K; 64K and 128K)
* More than 256 byte Internal RAM (XRAM addressable internal RAM)
* some device equip with special I/O function
* the most important thing is equip with UART Bootloader to support FLIP

flip flash uart programming

Just a minor addition to budhy: some of them don't have UART bootloader, but CAN or USB bootloader...

But the principle is the same.

The OP probably meant the plain old AT89C51, for which there is no ISP method (only parallel programming; and the same applies to AT89C52, AT89C55(WD), AT89Cx051). The newer AT89Sxxx can be ISP programmed; however, not via UART/CAN/USB, but via an ISP-like interface, (with reportedly problematic results if not performed correctly...)
