Intel LD87C54 microcontroller, an 8-bit device from the LD87C54 series, operates with an 8051 CPU core at a maximum clock frequency of 12MHz. This CMOS component features 16KB of UVPROM for program storage and 256 bytes of on-chip data RAM. It supports a 16-bit address bus and an 8-bit external data bus, with 32 general-purpose I/O lines and one serial I/O port. The device includes three timers and two external interrupts. Additional functionalities include a Boolean processor and on-circuit emulation capabilities. The LD87C54 is housed in a 40-pin CDIP package (R-GDIP-T40) and operates within a temperature range of -40°C to +85°C, with a supply voltage range of 5V to 6V. This microcontroller is utilized in industrial automation, telecommunications, and embedded control systems.
