The DS87C520-QCL is an 8-bit microcontroller from Analog Devices / Maxim Integrated, based on the 8051 architecture. It offers 16KB of One-Time Programmable (OTP) memory and 1KB of internal SRAM, making it suitable for applications requiring moderate code and data storage.
This high-speed microcontroller runs at clock rates up to 33MHz, with a 4-clock machine cycle architecture for efficient instruction execution. It features 32 I/O pins, three 16-bit timer/counters, and two full-duplex hardware serial ports. Peripherals include power-fail reset and a watchdog timer (WDT).
The DS87C520-QCL is available in a 44-pin PLCC (Plastic Leaded Chip Carrier) package, designed for surface mounting. It operates within a voltage range of 4.5V to 5.5V and has an operating temperature range of 0°C to 70°C.
Key features include compatibility with the 80C52 and 8051 instruction sets, an external oscillator type, and connectivity options such as EBI/EMI, SIO, and UART/USART.
The operating temperature range is 0°C to 70°C (TA).
The DS87C520-QCL is available in a 44-PLCC (16.59x16.59) package, also described as 44-LCC (J-Lead).
The program memory size is 16KB (16K x 8).
The RAM size is 1K x 8.
The maximum clock speed is 33MHz.
The operating voltage range is 4.5V to 5.5V.
