This is fantastic! Now if we get parts with SDRAM interface then that would be amazing We heard few things from ST guys but not sure we can share it here.
did you note that (for the first time, as far as I know) press release says “… .accelerate project completion by programming with high-level languages such as Java™, Microsoft® .Net or uClinux™…”?
Quoth the press release: [em]STM32F437IIH6 2MB Flash, 256KB RAM, Crypto/Hash processor in UFBGA176 package at $9.50 for 1000 units/year resale price.[/em]
I’d say, that’s how it can compete with the ChipworkX (which is $116.64 per for 250+). Plus:
[ul]4 KB + 80 Byte backup SRAM
Communication interfaces: 4x USART, 4x UART, 6x SPI, 3x I2C with digital filters, 2x CAN, SDIO, 2x USB OTG
Dedicated audio PLL and two full-duplex I2S channels
Ethernet 10/100 MAC with IEEE 1588 v2 support
2x 12-bit DAC, 3x 12-bit ADC, up to 17 16/32-bit timers[/ul]
Of course; they’re targeted at completely different sorts of projects. I was simply pointing out that SDRAM isn’t the only thing one might want to compare
I was effectively talking about the RAM, which is one of my achilles’heel at the moment, because as Gus said, I need some extra connectiviies that require more RAM !
A question I had: why not simply use SRAM compatible with the FSMC on the STM32? It certainly supports it, and as I understand it, SRAM would be lower-power anyway? Is it that it’s simply more expensive, or is it slower, or…?
That’s 8 mbits, meaning, 1 megabyte. I found a 16 megabyte (64mbit) memory for $60. Seems significantly more expensive. Is it faster and lower power?
8mbit SRAM starts at around $6 on DigiKey, maybe $3-$4 in the quantities that GHI would probably purchase. Seems like a fully-capable STM32 would be possible, but you’d need more space to fit multiple memory chips.
Yes those are small displays with parallel interface, not TFT interface. They are very bad to handle and so you won’t find a decent size display to work with STM.
One they use is like the one we had last year on panda, fez touch.
