Product details
Overview
P89LPC9103FTK,115 from NXP Semiconductors is a low-cost 8-bit microcontroller based on an accelerated two-clock 80C51 core, executing instructions in 2–4 clocks. It integrates 1 kB byte-erasable flash, 128-byte RAM, dual 16-bit timers, four-channel 8-bit ADC, DAC output, analog comparator, and enhanced UART with fractional baud rate generation. It operates from 2.4 V to 3.6 V with 5 V-tolerant I/O and targets compact embedded control in sensor interfaces and industrial monitoring.
For engineers reviewing the P89LPC9103FTK,115 datasheet, P89LPC9103FTK,115 pinout, P89LPC9103FTK,115 application, or P89LPC9103FTK,115 equivalent, this page delivers verified functional scope, validated HVSON10 package mapping, confirmed UART + ADC + comparator capability, and precise alternative part comparisons - all grounded in NXP's Rev. 03 product data sheet (10 July 2007).
Technical Context
The P89LPC9103FTK,115 implements a high-performance 80C51 CPU architecture with instruction cycle times of 136–272 ns using its internal 7.3728 MHz RC oscillator in clock-doubling mode. Its integrated peripherals include a four-input multiplexed 8-bit ADC, single DAC output, and one analog comparator with selectable reference - all sharing Port 0 pins under configurable I/O modes.
It supports In-Application Programming (IAP-Lite) with byte-erase capability for non-volatile data storage, features a watchdog timer with independent on-chip oscillator and eight prescaler options, and provides four interrupt priority levels plus keypad interrupt inputs (KBI1/KBI2) tied to Port 0 pins - enabling responsive human-interface sensing without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P89LPC9102FTK | No UART; includes T0/T1 toggle/PWM and CLKOUT; same HVSON10 package and ADC/DAC/comparator set. | Suitable for PWM-driven actuator control where serial comms are unnecessary. | Select when UART is not required but timer-based waveform generation or clock distribution is critical. |
| P89LPC9107FDH | TSSOP14 package; adds UART, T0/T1 toggle/PWM, and CLKOUT; retains identical ADC/DAC/comparator functionality. | Preferred for designs needing both UART and PWM outputs with more I/O routing flexibility. | Choose when board layout allows larger TSSOP14 and dual requirements for serial comms + PWM outputs exist. |
Compared with P89LPC9103FTK,115, the P89LPC9102FTK omits UART but adds PWM/CLKOUT for timing-critical control, while the P89LPC9107FDH expands I/O count and retains UART + PWM - making it suitable for feature-rich edge nodes where HVSON10 pin density is limiting.

FAQ
What is the maximum operating frequency of the P89LPC9103FTK,115?
The P89LPC9103FTK,115 operates with an internal RC oscillator factory-calibrated to 7.3728 MHz, extendable to 18 MHz using an external clock source. Instruction execution occurs in 2–4 clocks, yielding effective throughput up to 6× that of standard 80C51 devices - with cycle times ranging from 136 ns to 272 ns at 7.3728 MHz (clock-doubling mode).
Does the P89LPC9103FTK,115 support in-system programming?
Yes, the P89LPC9103FTK,115 supports In-Application Programming (IAP-Lite) with byte-erase capability. This allows firmware updates and non-volatile data storage directly within the target system without requiring external programming hardware - a key enabler for field-upgradable embedded devices.
What analog functions are integrated into the P89LPC9103FTK,115?
The P89LPC9103FTK,115 integrates a four-channel 8-bit ADC (AD10–AD13), one DAC output (DAC1), and one analog comparator (CIN1A/CIN1B/CMPREF). All analog functions share Port 0 pins and operate within the 2.4–3.6 V VDD range, enabling sensor interfacing, calibration offset correction, and threshold monitoring in a single chip.
Is the P89LPC9103FTK,115 pin-compatible with other members of the LPC910x family?
No - the P89LPC9103FTK,115 uses the HVSON10 package and shares pinout with P89LPC9102FTK, but differs functionally: P89LPC9103FTK,115 includes UART (TXD/RXD) and excludes T0/T1 toggle/PWM and CLKOUT present in P89LPC9102FTK. Pin compatibility exists only within identical package variants, not across functional variants.
What power-saving modes does the P89LPC9103FTK,115 support?
The P89LPC9103FTK,115 supports Idle mode and two reduced-power Power-down modes. In full Power-down mode with voltage comparators disabled, typical current consumption is less than 1 µA. Wake-up is supported via LOW interrupt input, enabling rapid resumption of operation - ideal for battery-powered sensor nodes.
