Maxim DS87C520 and DS83C520 EPROM/ROM High‑Speed Microcontroller Datasheet
The Maxim DS87C520 and DS83C520 are high‑speed EPROM/ROM microcontrollers compatible with the 80C52 instruction set. They include large on‑chip memory, two full‑duplex hardware serial ports, and 13 interrupt sources (six external). Power‑management and EMI‑reduction modes are provided, and the devices support a high‑speed architecture.
These microcontrollers are offered in multiple package types, including 40‑pin PDIP, 44‑pin PLCC, 44‑pin TQFP, and 40‑pin windowed CERDIP. The datasheet also references the accompanying High‑Speed Microcontroller User’s Guide and notes RoHS compliance for the windowed ceramic DIP package.
