Where can I buy AT89C2051-24PU 8-bit Microcontroller, 2KB Flash, 24MHz, 20-pin DIP in Egypt?
AT89C2051-24PU 8-bit Microcontroller, 2KB Flash, 24MHz, 20-pin DIP is available from Makers Electronics. Compare the offers above to find the best price.
How is it different from the AT89C4051?
The AT89C2051 has 2 KB of Flash, while the AT89C4051 has 4 KB. Both use the MCS-51 core and 20-pin packages, but the AT89C4051 has one UART and the AT89C2051 is limited to its smaller memory for program size.
Does it need an external crystal to run?
Yes. The 8051 core needs an external clock source, typically a crystal with two load capacitors connected to the XTAL pins. The 24 in the part number refers to the 24 MHz maximum clock rate.
