perfect substitute for pic 16c74

[harishwww]

i want to know perfect substitute for 16c74 pls help me

 

[nikhilele]

you can use 89C2051 or 89C4051
atmega8
attiny2313

 

[microcon555]

you can use 89C2051 or 89C4051
atmega8
attiny2313

Nothing is substitute for PIC16C74
2051 & 4051 is 51core
while atmega and tiny are avr

I think you can try pic16f877a

hey hey ops is asking for pic 16C74 micro controller equivalent you are suggesting atmel how this is possible?
try Microchip Technology Inc. is a Leading Provider of Microcontroller and Analog Semiconductors, providing low-risk product development, lower total system cost and faster time to market for thousands of diverse customer applications worldwide. and compare chips :-D

 

[nikhilele]

he has not mentioned whether he want pin to pin compatiblity or he wants function wise...
that is replacement for function wise..

yes i want pin as well as function wise replacement

 

[lockman_akim]

i think all the answer is at microchip.com..
go there and search for the datasheet and make your own comparison..

Hi,
Take a look at 16c77. It's quite similar, except an extended memory,etc. Peripherals are similar.
nikhilele,
The ATMEGA8 has 28 pins and ATTINY23 has 20 pins. They are better than the 16C77 function wise but the main difference would be the pin count. The 16c74 has 40 pins.

Hope this helps.
Tahmid.

i think 16c74 is absolute in the market / no more production if you see 16F877A is much similar to 16c74
The PIC16F877A CMOS FLASH-based 8-bit microcontroller is upward compatible with the PIC16C5x, PIC12Cxxx and PIC16C7x devices. It features 200 ns instruction execution, 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, a synchronous serial port that can be configured as either 3-wire SPI or 2-wire I2C bus, a USART, and a Parallel Slave Port.

Hi,
You can still find some 16c77 and 16c74 at mouser:
16c74:
16c74
16c77:
16c77

Hope this helps.

pls read https://www.edaboard.com/threads/81368/ before choosing your micro controller i think 16F877A is the perfect substitute for your device ? choice is yours my friend .

 

[Tahmid]

Hi,
I would suggest a move to 16F887 rather than 16F877A as it's newer and seems improved and enhanced and is compatible.

Hope this helps.
Tahmid.

 

[mishra12]

like Tahmid said
harrishwww your final choice 16F877

 

[pranam77]

As i guess you are from India, there are many vendors where you get the said device in abundant. But can you first let us all know why are you looking for a exact replacement?
