What are the smallest microcontrollers? - Electrical Engineering …
2013年10月9日 · ATtiny4, ATtiny5, ATtiny9 and ATtiny10 are packed in different 6pin packages some of them very small. They all have 4 I/O pins. Some of them ADC. Check for details on ATMEL site. EDIT: After some more search. Well, ATtiny20 in WLCSP package is even smaller. So, it becomes the smallest available Atmel microcontroller. (only in ATtiny20-UUR variant)
What are some smallest, cheapest microcontrollers with USB built in?
It also needs a voltage divider to set up slow speed and depending on operating voltage of the microcontroller, it may need a couple of zener diodes to limit voltage to D+ and D-. With it software USB works on microcontrollers as small as ATtiny45 for example. Two other popular microcontrollers for use with the library are ATtiny2313 and ATmega8.
What are the cheapest microcontrollers? - Electrical Engineering …
Especially when you're talking small quantities the price of the controller is only part of the picture. Suppose you need a 500 euro programmer to program the devices. This is OK if you need 100 000 devices a year, but if you need 50 controllers, the programmer adds 10 euro to a device which at 1 euro may be cheap in itself.
What is a good microcontroller for Ethernet applications?
2010年12月10日 · Contiki is designed for microcontrollers with small amounts of memory. A typical Contiki configuration is 2 kilobytes of RAM and 40 kilobytes of ROM. The uIP TCP/IP Stack: The open-source uIP TCP/IP stack provides TCP/IP connectivity to tiny embedded 8-bit microcontrollers, with maintained interoperability and RFC standards compliance.
A very small microcontroller that can be programmed wirelessly
2013年5月25日 · For fun, I'm building a microcontroller and a couple of sensors into a toy. The microcontroller must fit into a 2 cm wide cylinder. Also, removing it from the toy takes some time, so I'd like to be able to program it wirelessly. It doesn't matter how (IR, wifi, Bluetooth), as long as I don't have to remove it from the toy during testing.
Small, inexpensive microcontroller capable of high speed SSP?
I'm looking for a small microcontroller that can accept high speed serial data. NXP calls it an SSP peripheral -- it works with an SPI, Microwire or SSI bus, and I'm using it in a 32-bit SSI application. By small I mean both physically (under 50 pins) and in terms of RAM/Flash (the 8 KB RAM and 32 KB Flash is more than enough).
switches - How to switch power of microcontroller by button ...
Many modern microcontrollers have sleep current well below the self-discharge current of even small batteries. You can have the pushbutton simply drive the I/O pin of the micro, which then toggles itself between sleep and active mode each button press.
What microcontroller should I use? - Electrical Engineering Stack …
When bit banging, the bottleneck is going to be the microcontroller's USB interface. So you may want to shift protocols such as I2C and SPI down to the microcontroller. For this you could use my Bus Ninja. Adding additional Teensies to your setup is simple, you just need one USB port per device, presenting one virtual COM port per device. (Note.
One large microcontroller, or lots of small microcontrollers?
Small quantities. If you are doing a one-off or small run of these devices, then your development efforts are going to swamp your per-item costs, and you should focus on what will be easiest/fastest for your to develop, rather than the cost/size of the microelectronic. In general encapsulation can decrease complexity, increasing your productivity.
8-Bit / Small Zephyr RTOS Microcontrollers? [closed]
For many applications with a single core on a small microcontroller, a full RTOS is overkill. What's needed instead is a way to handle various inputs and events in real time, and state machines are great for that.
