How do I choose a micro controller?
10 Steps to Selecting a Microcontroller
- Step 1: Make a list of required hardware interfaces.
- Step 2: Examine the software architecture.
- Step 3: Select the architecture.
- Step 4: Identify Memory Needs.
- Step 5: Start searching for microcontrollers.

How much is a micro controller?
In 2018, 8-bit microcontrollers can be bought for $0.03, 16-bit for $0.393 (1,000 units, but at $0.563 for 100 or $0.349 for full reel of 2,000), and 32-bit for $0.503 (1,000 units, but at $0.466 for 5,000). A lower-priced 32-bit microcontroller, in units of one, can be had for $0.891.
Why is microcontroller cheap?
The starting price is lower, because there is no matching CPU for the entry-level MCU’s. CPU’s don’t have on-chip flash memory and peripherals. The very same device with more on-chip memory can cost double the price.
What is the cheapest MCU?
The PMS150C is their lowest cost offer at $0.033, the original “3 cent MCU”. This device comes with 1 kiloword of one-time programmable memory and 64 bytes of RAM.
How many types of microcontroller are available?
AVR Microcontrollers are classified into three types: TinyAVR – Less memory, small size, suitable only for simpler applications. MegaAVR – These are the most popular ones having a good amount of memory (up to 256 KB), the higher number of inbuilt peripherals, and suitable for moderate to complex applications.
What is microcontroller IC?
A microcontroller ic is a small computer on a single metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. A microcontroller is also known as an embedded controller.
Which is cheaper microcontroller or microprocessor?
The complementary metal-oxide-semiconductor technology used in making a microcontroller is far cheaper than the material used in making microprocessors. The external components that are required by the applications made with microcontrollers are less in number, so the cost is minimal.
What are the cheapest microcontrollers in the world?
Under given is the list of world cheapest microcontrollers ICs, from different vendors & makers of the world. Microchip Technology / Atmel ATTINY9-TS8R Mouser No:556-ATTINY9-TS8R Mfr. No:ATTINY9-TS8R
How much does a 32-bit microcontroller cost?
It costs a little over $1 in volumes of around 10k pieces. It runs at 20 MHz and includes 32 KB of Flash and 2KB of RAM. On the other hand, you can purchase a 32-bit microcontrollers running at 48 MHz with similar memory for only 60 cents.
What is a microcontroller (MCU)?
Microcontrollers (MCUs) have come a long way since the pioneering 4-bit Intel 4004 hit the market back in the 1970s. Today, they’re the heart of most embedded systems, from automotive engine control systems, medical devices, toys, and more, serving as low-cost, compact, single chip computers.
How to select the right microcontroller?
When selecting a microcontroller, Suresh recommends that designers consider core size, peripherals required, speed, power consumption, flash memory, cost of ownership, and support ecosystems. Many of these factors will depend on design requirements. For example, core size directly impacts cost, hence designers should only select as much as needed.
