Product Overview: NXP P89LPC935FDH Microcontroller

The NXP P89LPC935FDH is a highly integrated microcontroller that is part of the P89LPC900 family of low-power 8-bit microcontrollers. This product is designed for applications requiring high-performance operation at low power consumption in a cost-effective package. It is particularly suitable for battery-powered devices, industrial control systems, and consumer electronics.

Key Features

• Core: The P89LPC935FDH is built around a high-performance 8-bit microcontroller core with an accelerated two-clock 80C51 instruction set that delivers up to six times the performance of the standard 80C51 processor at the same clock frequency.
• Memory: It comes with 8 KB of on-chip flash memory, which is typically more than sufficient for most embedded applications. The flash memory is in-system programmable (ISP) and in-application programmable (IAP) for greater flexibility in firmware development and updates.
• Digital Peripherals: The device includes a variety of digital peripherals such as multiple 32-bit timers, a 10-bit A/D converter with eight multiplexed inputs, and two enhanced UARTs for serial communication.
• Power Efficiency: It features multiple power-down modes including Idle and Power-down with external interrupt wake-up, which significantly reduce power consumption and extend battery life in portable applications.
• I/O Ports: The microcontroller offers 21 general-purpose I/O pins, providing ample interfacing capabilities with external circuits and devices.
• Clock Options: A flexible clocking system includes an on-chip oscillator that can be driven by a crystal, an external clock, or an internal RC oscillator, allowing the system designer to optimize power consumption and processing speed.
• Package: It is available in a TSSOP28 package, which is ideal for space-constrained applications.
