RE: [lpc2000] Re: interesting info from Atmel / STM / Analog
I'll give it a shot myself;
"super-simple" MP3 player!
1) needs at least 128KB internal flash (can't connect to external MMC
2) needs USB client interface that's 2 pins minimum (integrated
transceiver) - for download from PC/MAC
3) needs SPI interface or I2S - that's another 3 pins
(requirements depend on whether you use a VS1001 or
similar Micronas-type fully integrated
or just a audio-DAC w.line-amp etc.) Typically
these have separate data(audio) and control i/f, so it won't
That was another 3 pins - now we don't have any
(need Vcc/GND and Reset - probably
4) forget about ETM or JTAG - debug will be by listening (probably an
awkward process ...;-)
Rather far-fetched, but it's the best I can do:-)
PS: I won't accept any low-bandwidth, low
type of application (example: reading tempsensor, sending value out the
Those are exactly what 8-bitters are for!
Rgd. Atmel AT91 packaging -
there's a new selection guide (SAM - "Smart ARM
on the AT91 website
(http://at91.com) showing several new,
(32-356KB internal Flash).
The smallest one
(AT91SAM7S32) comes in a LQFP48(=TQFP48?) package.
That is, on par w. Phillips - so they *are* probably watching
PS: what "Smart" stands for is not yet revealed,
but my guess is that it will be possible to program the
Flash through the USB client port (like on their
bigger ARM9 - AT91RM9200).
PS,PS: just curious - could you give a "Real-Worl"
of an appliction for an 8-pin ARM7, where a
8-bit MCU wouldn't do??

they will be too similar to the Atmel devices.

8-pin ARM7 would also be useful.
