YINGHUA PIC16LF1789-IPT LQFP44 semiconductor

PIC16LF1789-IPT Microcontroller

The YINGHUA PIC16LF1789-IPT is a low-power 8-bit microcontroller housed in a 44-pin LQFP package. It serves engineers developing embedded control applications where minimal energy consumption and compact board footprint are primary requirements. The device integrates core peripherals for general-purpose I/O and timing functions. It is not suited for designs needing high-speed floating-point math or integrated wireless connectivity.

Sustained Load Behaviour

Under continuous operation the IC maintains stable performance within its specified voltage and temperature ranges. The low-power architecture limits thermal rise during extended duty cycles, reducing the need for active cooling on the PCB. Current draw remains predictable when peripherals are enabled according to the datasheet configuration. Designers must verify timing margins at the target clock frequency for their specific firmware loop.

Installation Notes

The 44-pin LQFP footprint requires precise solder-paste stencil alignment and a reflow profile matched to the package thermal mass. Incorrect pad dimensions or excessive dwell time can lead to bridging or tombstoning defects. In-circuit programming uses standard ICSP pins; verify voltage levels on the programmer header before connection. No bootloader is pre-installed, so initial firmware load must occur via a hardware programmer.
