caption_attribution_description: English: An Intel 8049 microcontroller, as used in a HP3478A Multimeter. This chip was manufactured in the 48th week 1990.
context_page_description: The MCS-48 microcontroller series, Intel's first microcontroller, was originally released in 1976. Its first members were 8048, 8035 and 8748. Initially, this family was produced using NMOS technology. In the early 1980s, it became available in CMOS technology. It was still manufactured into the 1990s to support older designs that still used it.
  The MCS-48 series has a modified Harvard architecture, with internal or external program ROM and 64–256 bytes of internal RAM. The I/O is mapped into its own address space, separate from programs and data. The 8048 is probably the most prominent member of Intel's MCS-48 family of microcontrollers.
  Though the MCS-48 series was eventually replaced by the very popular MCS-51 series, even at around year 2000 it remained 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.
