Does code read protection exist on the LPC2106 ?

Started by smt5211 October 6, 2004

Hi,

I know that code read protection exists on the
LPC2114,2124,2212,2214. Does code read protection exist on the
LPC2106.

If it doesnt, will the bootloader eventually support this feature?

If the LPC2106 doesnt have code protection, then we're going to have
to use a PIC (gasp! horror!)

No (I think we may need to start building a FAQ).

>If it doesnt, will the bootloader eventually support this feature?

Also no, There was a recent post from philips_apps on this, apparently a
re-spin of the silicon would be required.

"Hello Armando,

Richard is right, The LPC2104 / 2105 and 2106 do not support code read
protection. Somebody with a JTAG debugger can go in an read your code.
All other devices of the LPC2000-family do support code read protection.

Hi Shane,

As Robert said the LPC210X family does not support code read
protection (great mistake from Philips). If you are working in a cost
effective product, probably you can use a PIC or wait for the
AT91SAM7S Atmel ARM7 family.

Just for information LPC2210 too ? (no flash integrated ...)

With no internal flash there is nothing to protect. The point is moot.

Protecting external flash would require some sort of encrypted bus.

It's just for complete the list of LPC who have'nt code read protection.

I find this groups very usefull, and interresting, thank for all.
