Things are happening! Not sure exactly what "release" means, maybe first chips shipping, add to taobao store?Release 1st Sept.

Re: Here We Go: Release 1st Sept.
txs!
..what we do without you..
txs!
240 ( 220 ? ) MHz CPU clock - fine
one think over: ESP32-wRover ( think he mean wifi Rover )
does John Lee mean with "4 MByte of SRAM" the extern possible from a SRAM over (h)SPI ? or mistake and 4 MBit ?

Yes I think so, external ram. Flash and SRAM can both be used with cache.rudi ;-) wrote: does John Lee mean with "4 MByte of SRAM" the extern possible from a SRAM over (h)SPI ? or mistake and 4 MBit ?

have thinked so,too. txs for confirm. i was little unsure what he mean.WiFive wrote:Yes I think so, external ram. Flash and SRAM can both be used with cache.rudi ;-) wrote: does John Lee mean with "4 MByte of SRAM" the extern possible from a SRAM over (h)SPI ? or mistake and 4 MBit ?
nice 'accelerator's datasheet - one thing is not on the list just in time - hope for the 'CAN' Controller implant
think we need for receive/send datatelegram one extern transceiver like MCP2551 or the TJA1050..
what you mean about the 'CAN' Controller implant ?

good news
Where to go on sale?

Re: Here We Go: Release 1st Sept.
we have 3x I2C in the ESP32 release?
( beta was/is 2xI2C )
wide supply volt range operation changed
SRAM changed
and DMIPS changed
fine!
( beta was/is 2xI2C )
in datasheet 2x I2C toobefore wrote: 3 x UARTs, including hardware flow control
3 x SPI
2 x I2S
12 x ADC input channels
2 x DAC
2 x I2C <<<<<<<<<<<<<<<<<<<<<<<<<<<<<
PWM/timer input/output availabe on every GPIO pin
OpenOCD debug interface with 32 kB TRAX buffer
SDIO master/slave 50 MHz
Supports external SPI flash up to 16 MB
SD-card interface support
wide supply volt range operation changed
tobefore wrote: 2.2V to 3.6V operating voltage
before wrote: 2.0 to to 3.6V operating voltage
SRAM changed
tobefore wrote: Integrated 520 KB SRAM
before wrote: 512 kByte SRAM
and DMIPS changed
tobefore wrote: 600 DMIPS
We have 650 DMIPS?John Lee on Twitter wrote: "link twitter"
..What will you do with 650 DMIPS? *drum roll*..
fine!

Now where can we find 32mbit serial SRAM??rudi ;-) wrote:have thinked so,too. txs for confirm. i was little unsure what he mean.WiFive wrote:Yes I think so, external ram.

i think we do this from spi slave contected SPI Flash
have a look: CY62177EV30LL-55ZXI ( parallel )
SRAM 32Mb 3V 55ns 2M x 16 LP SRAM
option 2
- Micro SD cards are serial interface and only need a couple of control lines.
- You can always bit-bang a parallel bus. To safe pins you could use 74xx595 shift registers to make the address lines
- Option 3
-Option 4

Re: Here We Go: Release 1st Sept.
about the supply voltage range. the main issue is not with ESP32, but with the flash chips which usually runs off 3.3V, with the exception of some vendors which went as low as 2.2V. with ESP32, we decided to try using 1.8V flash; hence we can now go to 2.0V.
