P89LPC9107FN,112

Microcontrollers Overview

The P89LPC9107FN is an 8-bit microcontroller based on the NXP P89LP family, utilizing a high-performance 80C51 core that executes instructions in two to four clocks. It features 1 kB of byte-erasable flash memory organized into sectors and pages, allowing for non-volatile data storage via single-byte erasing. The device includes 128 bytes of RAM, two 16-bit timer/counters, a 23-bit system timer/RTC, and a four-input multiplexed 8-bit ADC with a DAC output. It operates within a VDD range of 2.4 V to 3.6 V with 5 V tolerant I/O pins.

Microcontrollers Feature Summary

• Accelerated 80C51 CPU architecture providing instruction cycle times significantly faster than standard 80C51 devices.
• Integrated analog peripherals including an 8-bit A/D converter and a single DAC output channel.
• Enhanced UART supporting fractional baud rate generation, break detect, and automatic address detection.
• High-accuracy internal RC oscillator factory calibrated to 1%, enabling operation without external oscillators.

Microcontrollers Applications

• Low-cost embedded control systems requiring reduced component count
• Battery-powered applications utilizing low voltage operation and power-down modes
• Industrial monitoring using integrated analog-to-digital conversion

Microcontrollers Procurement Notes

Verify the specific package type matches the required footprint, as the P89LPC9107 series is available in TSSOP14 and DIP14 configurations. Confirm the operating temperature range aligns with the -40 °C to +85 °C specification. Ensure the design accounts for the 2.4 V to 3.6 V supply voltage requirements and utilizes the 5 V tolerant I/O capabilities where necessary.

Microcontrollers Selection Notes

Select this component when a cost-effective solution with an accelerated 80C51 core is needed. It is suitable for designs requiring onboard flash programming and analog signal processing. Consider the DIP14 package for through-hole mounting or TSSOP14 for surface mount applications. Evaluate the pin count against the specific I/O and peripheral requirements of the target application.
