Intel QD8749H is an 8-bit microcontroller featuring the 8048 CPU architecture. This NMOS device operates at a maximum clock frequency of 11MHz and is equipped with 2048 bytes of UVPROM for program storage and 128 bytes of on-chip RAM. It offers 24 general-purpose I/O lines, a 12-bit address bus width, and an 8-bit external data bus. The QD8749H includes one timer and one external interrupt input. Packaged in a 40-pin CDIP (CERAMIC, GLASS-SEALED DIP) with a terminal pitch of 2.54mm, it supports through-hole mounting. Typical applications include industrial control and embedded systems requiring UV erasable program memory. Operating temperature range is 0°C to 70°C with a supply voltage of 5.0V nominal.
