P87C51FA-4B Description

Short technical summary and product information.

This NXP USA Inc. P87C51FA-4B is an 8-bit microcontroller based on the 8051 architecture. It offers 8KB of One-Time Programmable (OTP) memory for firmware storage and 256 bytes of RAM. The device operates at a speed of 16MHz and supports a wide supply voltage range from 2.7V to 5.5V.

 

With 32 general-purpose I/O pins, the P87C51FA-4B is suitable for various embedded control tasks. It includes essential peripherals such as Power-on Reset (POR) and Pulse-Width Modulation (PWM), along with connectivity options like EBI/EMI and UART/USART. The microcontroller is designed for surface mounting and comes in a 44-lead PLCC package.

 

Operating within a temperature range of -40°C to 85°C, this component is built for reliability in demanding environments. Its OTP memory type means firmware is programmed once, making it ideal for applications requiring fixed code. The device is noted as obsolete but may be found in existing inventories for legacy systems or repair purposes.
