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.
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.
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 .
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?
