MCS213 Report




Intel 8048


-The Intel 8048 microcontroller

-Intel's first microcontroller

-was used in the Magnavox Odyssey² video game console

-The 8048 is probably the most prominent member of Intel's MCS-48 family of microcontrollers.

-A 8048-family chip with UV EPROM, the 8749.

-This one is made by NEC.

-The 8048 has a Modified Harvard architecture, with internal or external program ROM and 64–256 bytes of internal (on-chip) RAM.

-Though the 8048 was eventually replaced by the very popular Intel 8051/8031, even at the turn of the millennium it remains quite popular, due to its low cost, wide availability, memory efficient one-byte instruction set, and mature development tools.

-Because of this it is much used in high-volume consumer electronics devices such as TV sets, TV remotes, toys, and other gadgets where cost-cutting is essential.




Intel 8051

-The Intel 8051 is a Harvard architecture

-single chip microcontroller which was developed by Intel in 1980 for use in embedded systems.

-Intel's original versions were popular in the 1980s and early 1990s
-8051-compatible devices manufactured by more than 20 independent manufacturers including Atmel, Infineon Technologies (formerly Siemens AG), Maxim Integrated Products (via its Dallas Semiconductor subsidiary), NXP (formerly Philips Semiconductor), Nuvoton (formerly Winbond), ST Microelectronics, Silicon Laboratories (formerly Cygnal), Texas Instruments and Cypress Semiconductor.

-Intel's official designation for the 8051 family of µCs is MCS 51.
