PIC16LF1507T-I/SS - 20MHz 8-bit MCU, 3.5KB Flash | Microchip
MPN: PIC16LF1507T-I/SS ✓ Hoạt độngPIC16LF1507T-I/SS Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals onto one die. PIC microcontrollers use a Harvard architecture with a reduced instruction set, executing one instruction per clock cycle (excluding branches). The "LF" prefix designates the wide-voltage, low-power variant designed for operation from 1.8V to 3.6V, making it suitable for 2xAA/coin-cell applications. Within the power-management hierarchy, PIC16 MCUs sit at the entry-level 8-bit tier, balancing cost, peripheral integration, and ease of development with the free MPLAB X IDE ecosystem.
Key features include 18 I/O pins with interrupt-on-change capability, 4 standalone PWM channels, a Complementary Waveform Generator (CWG), a Numerically Controlled Oscillator (NCO), two Configurable Logic Cells (CLC), an integrated temperature indicator, and 128 bytes of EEPROM emulation in Flash. The PIC16 enhanced mid-range core delivers 49 instructions with 16-level hardware stack and self read/write Flash capability.
The PIC16LF1507 utilizes Microchip's enhanced mid-range core implemented on CMOS process technology. The CWG module generates complementary outputs with programmable dead-band control for half-bridge drivers, while the NCO provides fine-frequency clock generation for cost-effective waveform synthesis without a dedicated DDS chip. The 10-bit ADC includes a voltage reference and supports 12 analog input channels with hardware acquisition timer.
Typical applications include battery-powered IoT sensor nodes, low-cost consumer appliances, LED lighting controllers, small motor control (PWM/CWG-driven), e-metering sub-systems, and general-purpose logic replacement. Its 18 I/O count and 20-pin SSOP footprint fit compact PCBs where PIC12/PIC16 baseline cores are insufficient but PIC18/XLP Cortex-M0+ are over-spec.
When designing with this device, ensure Vdd decoupling uses a 0.1uF ceramic capacitor placed within 5mm of the Vdd pin. The internal 16MHz oscillator provides +/-2% accuracy across -40C to +85C; switch to an external crystal if a precision UART baud rate is required. Configure unused I/O as outputs with low level to minimize current draw.

Ghi chú thiết kế
Place a 0.1uF ceramic decoupling capacitor within 5mm of the Vdd pin (pin 7) and a bulk 1uF-10uF capacitor near the Vss pin (pin 8) to suppress switching noise. For battery-powered applications, the PIC16LF1507T-I/SS XLP technology provides typical sleep currents below 1uA at 1.8V - verify with the datasheet's electrical characteristics table for the specific Sleep mode (Sleep vs Deep Sleep vs Watchdog Timer-only) chosen.
The MCLR pin (pin 3, shared with RA5) MUST be pulled high via a 10k resistor to Vdd for normal operation. If left floating, the device will randomly reset due to noise. The ICSPDAT/ICSPCLK pins (pins 19, 20) require series 10k resistors for in-circuit serial programming if these pins are used for general I/O - omitting them can interfere with programming. Do not connect a capacitor directly to MCLR without consulting Microchip's ICSP specification.
The 20-pin SSOP (Shrink Small Outline Package) has a 0.65mm pitch and 5.30mm body width. Per Microchip's land pattern recommendation in the package datasheet, use 0.40mm-wide pads with 0.20mm solder mask expansion for reliable reflow soldering. The thermal pad is not present on this package; standard SMT reflow profiles (JEDEC J-STD-020) at 250C peak temperature are appropriate for lead-free assembly.
Route the analog ADC inputs (AN0-AN12) away from digital switching traces and PWM outputs to minimize coupling noise. Use a ground pour on the bottom layer as a return path, with single-point connection between analog and digital ground if the design uses separate analog/digital supplies. For high-accuracy ADC readings, the voltage reference (Vref+ on RA3) should be bypassed with 0.1uF and 10uF capacitors at the pin.
