microcontroller choice -- 2 uart + 3.3V

[shashavali_m]

Hi all, i want microcontroller which is having 2 uart and which runs with 3.3V,please help me Thanking u all.

 

[jojokatada]

try to check pic16LF877a L stand for low voltage operate from 2v to 5.v

 

[revolt]

The atmega64L and 128L (8 Bit)from Atmel are running with 3.3V and has two UARTs.

or the MSP430F149 (16 Bit) from Texas.

 

[Bingo600]

Or the ATMEL ATmega 162L
You can get that one in 40 Pin-PDIP for development , and SMD TQFP

[C-Man]

You can also use some of the PIC18 devices like 18LF6621, 18LF6520, 18LF6620 and many more.

best regards

Another choise 32-bit LPC213x from Philips

[Mr_Programmer]

another possibility is the MSP430, new devices comming with 2 UARTS and the voltage is also ok...

Hi

The MSP430F169 can run down to 2V and have 2 UART or 1 UART + SPI or 1 UART + I2C or 1 SPI + I2C or you can MUX any combinetion you want


All the best

Also, SiLabs ( www.silabsl.com) has several 8051-compatible variants and all are 3,3V powered. Look for F02x, F12x or F13x devices...

Hi
The cypress series are best for it. For example high speed controllers such as CY7C68013 or CY7C68013A.

Aslo check Microchip dsPIC!

 

[ahmbay]

also check renesas r8c series

 

[alexan_e]

also check renesas r8c series

The last post in this thread was 6 years ago...
I assume they have found a solution by now ...;-)
