Product details
Overview
P89LPC9102FTK,115 from NXP Semiconductors is a low-pin-count 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 (T0/T1), 23-bit system timer/RTC, four-channel 8-bit ADC, single DAC, analog comparator, and clock output (CLKOUT). Designed for space-constrained embedded control in battery-powered sensors and industrial I/O modules.
For engineers reviewing the P89LPC9102FTK,115 datasheet, P89LPC9102FTK,115 pinout, P89LPC9102FTK,115 application, or P89LPC9102FTK,115 equivalent, key selection criteria include its HVSON10 package, internal RC oscillator with ±1 % calibration, 2.4–3.6 V operation with 5 V-tolerant I/O, ultra-low-power Power-down mode (<1 µA), and absence of UART - distinguishing it from P89LPC9103/9107 variants.
Technical Context
The P89LPC9102FTK,115 implements a high-efficiency 80C51 derivative core with instruction cycle times of 136–272 ns using its factory-trimmed 7.3728 MHz internal RC oscillator (doubling enabled), enabling power savings versus standard 8051s. Its architecture supports In-Application Programming (IAP-Lite) and byte-erase flash, allowing code memory to serve as non-volatile data storage without external EEPROM.
System-level integration includes a dedicated watchdog timer with independent on-chip oscillator and eight prescaler options, brownout reset with interrupt capability, four interrupt priority levels, keypad interrupt detection on Port 0 pins, and programmable slew-rate outputs (≥10 ns ramp time) to reduce EMI. All I/O pins feature Schmitt-trigger inputs and 20 mA LED drive capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P89LPC9103FTK,115 | Includes UART (TXD/RXD), lacks CLKOUT and T1 toggle/PWM; same HVSON10 package and flash/RAM specs | Suitable for serial communication interfaces (e.g., RS-232/485 modems), not for clock distribution or dual PWM generation | Select when UART connectivity is required and CLKOUT/T1 PWM are unnecessary |
| P89LPC9107FDH,118 | 14-pin TSSOP package; adds UART, CLKOUT, T0/T1 toggle/PWM; higher pin count enables more I/O and serial interface | Fits applications needing both serial comms and clock output (e.g., synchronized sensor networks), but requires larger PCB footprint | Choose when additional I/O, UART, and CLKOUT are needed and HVSON10 size constraint is relaxed |
Compared with P89LPC9103FTK,115 and P89LPC9107FDH,118, the P89LPC9102FTK,115 uniquely delivers CLKOUT and dual timer PWM in the smallest HVSON10 package without UART overhead - optimizing for timing-critical, space-constrained control where serial comms are handled externally.

FAQ
Does the P89LPC9102FTK,115 include a UART interface?
No, the P89LPC9102FTK,115 does not include a UART. This is confirmed in Table 1 (Product comparison overview) of the datasheet, which explicitly marks UART as "–" for P89LPC9102. The P89LPC9102FTK,115 instead provides CLKOUT, T0, and T1 functions - making it distinct from the UART-equipped P89LPC9103FTK,115 and P89LPC9107FDH,118 variants. Designers requiring serial communication must use external UART ICs or select alternate models.
What is the maximum operating frequency of the P89LPC9102FTK,115?
When using the internal 7.3728 MHz RC oscillator with clock doubling enabled, the P89LPC9102FTK,115 achieves an effective CPU clock of 14.7456 MHz, yielding instruction cycle times of 136–272 ns. With an external 18 MHz clock, cycle times improve to 111–222 ns. The device does not support frequencies above 18 MHz, and oscillator selection is configured via User Configuration Registers.
Can the P89LPC9102FTK,115 operate from a 3.3 V supply while driving 5 V logic?
Yes, the P89LPC9102FTK,115 operates from 2.4 V to 3.6 V and features 5 V-tolerant I/O pins - meaning all GPIOs (including P0.x and P1.x) can be safely pulled up to or driven by 5.5 V signals without damage. This allows direct interfacing with legacy 5 V logic families while maintaining low-power 3.3 V core operation, simplifying level-shifting requirements in mixed-voltage systems.
How many analog input channels does the P89LPC9102FTK,115 support?
The P89LPC9102FTK,115 supports four analog input channels (AD10–AD13) multiplexed onto Port 0 pins P0.1, P0.2, P0.3, and P0.4. These share physical pins with keypad interrupt and comparator functions, enabling flexible analog acquisition in resource-constrained designs. The integrated 8-bit ADC provides sufficient resolution for sensor interfacing, battery monitoring, and industrial control feedback loops.
Is the P89LPC9102FTK,115 pin-compatible with other devices in the LPC910x family?
No, the P89LPC9102FTK,115 is not pin-compatible with P89LPC9103FTK,115 or P89LPC9107FDH,118. While all three share the HVSON10 package, their pin functions differ significantly: P89LPC9102FTK,115 assigns P0.7 to T1/CLKOUT, whereas P89LPC9103FTK,115 uses that pin for n.c., and P89LPC9107FDH,118 uses a 14-pin TSSOP. PCB layout must be specific to P89LPC9102FTK,115's 10-pin HVSON mapping.
