The Intel LS87C51FA-20 is an 8-bit microcontroller featuring a 20MHz CMOS core. This component offers 8KB of One-Time Programmable Read-Only Memory (OTPROM) and 256 bytes of on-chip data RAM. It supports a 16-bit address bus and an 8-bit external data bus. The device includes 32 general-purpose I/O lines, three timers, one serial I/O port, and two external interrupt inputs. Additional features include a Boolean processor and on-circuit emulation capabilities. Operating within a supply voltage range of 5V to 6V, this microcontroller is housed in a 44-pin PQFP package with a 0.8mm terminal pitch. The Intel LS87C51FA-20 is suitable for applications in industrial automation, consumer electronics, and embedded systems requiring reliable 8-bit processing. Operating temperature range is -40°C to +85°C.
