Download File 16. Motorola Chip PIC16F88 18 pin

The Intel 8051 was a Harvard architecture single chip microcontroller (lC) developed by Intel in 1980 for use in embedded systems. It was extremely popular in the 1980s and early 1990s, but today it has largely been superseded by a vast range of enhanced devices with 8051-compatible processor cores that are manufactured by more than 20 independent manufacturers including Atmel, Maxim IC (via its Dallas Semiconductor subsidiary), Philips, Winbond, and Silicon Laboratories. Intel's official designation for the 8051 family of lCs is MCS 51. 10 pages.

The 89C51RX+ devices contain a non-volatile FLASH program memory (up to 64 k bytes in the 89C51RD+) that is both parallel programmable and Serial In-System Programmable. In-System Programming allows devices to alter their own program memory, in the actual end product, under software control. This opens up a range of applications that can include the ability to field update the application firmware. 50 pages.


Download File 18. P89V51RD2-01 8-bit 80C51 5 V low power 64 kB Flash microcontroller with 1 kB RAM

The P89V51RD2 is an 80C51 microcontroller with 64 kB Flash and 1024 bytes of data RAM. A key feature of the P89V51RD2 is its X2 mode option. The design engineer can choose to run the application with the conventional 80C51 clock rate (12 clocks per machine cycle) or select the X2 mode (6 clocks per machine cycle) to achieve twice the throughput at the same clock frequency. Another way to benefit from this feature is to keep the same performance by reducing the clock frequency by half, thus dramatically reducing the EMI. 75 pages.
