The Intel LD87C52 is an 8-bit microcontroller built on CMOS technology, operating at a maximum clock frequency of 24MHz. This device features an 8KB UVPROM for program memory and 256 bytes of on-chip data RAM. It offers 32 general-purpose I/O lines, three timers, and one serial I/O port. The microcontroller supports a 16-bit address bus and an 8-bit external data bus. Additional features include a Boolean processor and on-circuit emulation capabilities. Designed for operation within a temperature range of -40°C to +85°C, it requires a supply voltage between 5V and 6V. The LD87C52 is packaged in a 40-pin CDIP (CERAMIC, GLASS-SEALED) with through-hole mounting. This component finds application in industrial control, automotive systems, and embedded systems requiring robust 8-bit processing.
