MPN: PIC16LF1907T-I/PT ✓ פעילPIC16LF1907T-I/PT סקירה
A PIC microcontroller (Peripheral Interface Controller) is a family of 8-bit RISC microcontrollers from Microchip featuring Harvard architecture, separate program and data buses, and a compact instruction set optimized for embedded control. The PIC16F190X family sits in the mid-range PIC16 lineup (PIC10/12/16/18 hierarchy), offering a balance of low power, peripheral integration, and small footprint; the 'LF' prefix denotes the wide-voltage low-power variant, and 'XLP' (eXtreme Low Power) is Microchip's branded nanoWatt technology achieving quiescent currents in the microamp range for sleep states.
Key features include 14KB Flash program memory, 512 bytes RAM, an integrated LCD driver supporting up to 116 segments, a 10-bit ADC with up to 17 channels, multiple communication peripherals (EUSART, MSSP I2C/SPI), and nanoWatt XLP sleep currents typically below 1 uA. The 'T' suffix denotes Tape & Reel packaging for high-volume assembly.
Internally, the PIC16LF1907 uses an enhanced mid-range 8-bit core with a hardware multiplier, 16-level hardware stack, and configurable oscillator block supporting internal 16 MHz HFINTOSC, 31 kHz LFINTOSC, and external crystal modes. The integrated LCD driver includes charge pump and voltage regulator blocks enabling direct glass driving without external bias components.
Typical applications include battery-powered consumer products with segment LCDs (thermostats, scales, remote controls), industrial sensor transmitters with LCD readouts, low-power IoT edge nodes, metering and instrumentation displays, and white-goods user interfaces. The XLP technology is specifically engineered to extend coin-cell battery life beyond five years in intermittent-duty applications.
When designing with this device, budget I/O pins carefully - the 44-pin TQFP exposes 36 GPIO lines but several are multiplexed with the LCD segment outputs, requiring pin allocation trade-offs when both LCD and digital I/O are required.

הערות תכנון
The PIC16LF1907T-I/PT's nanoWatt XLP technology achieves sub-1 uA sleep currents when properly configured. Engineers should disable unused peripherals via the PMD (Peripheral Module Disable) registers before entering Sleep mode. The VREGPM bit selects the low-power voltage regulator mode, and the IDCIDSLE bit controls idle mode current. Average current in intermittent-duty applications (sensor reading every 10 seconds) can drop below 5 uA with proper configuration, enabling multi-year battery life from a CR2032 coin cell.
When designing the PCB for the PIC16LF1907T-I/PT in the 44-pin TQFP (PT) package, place the VDDCORE capacitor (typically 0.1 uF) as close as possible to pin 9 (VDD) and pin 10 (VSS) to minimize supply noise. The LCD segment pins share GPIO functions; if the LCD is not used, configure unused segment pins as digital outputs driving low to minimize crowbar current. Maintain a continuous ground plane beneath the IC to reduce EMI from the internal oscillator.
Do not leave the MCLR pin (pin 38) floating - it must be tied to VDD through a 10 kOhm pull-up resistor or driven by the programmer/debugger. The ICSPDAT and ICSPCLK pins (RB6/RB7) require series resistors or careful routing if used as GPIO, because in-circuit programming during production may otherwise interfere with connected circuitry. The LFINTOSC and HFINTOSC tolerances are +/-2% over voltage and temperature; if precise timing is required, use an external crystal.
