PIC16F1507T-I/GZ - 8-bit MCU 3.5KB Flash 12 I/O | Microchip
MPN: PIC16F1507T-I/GZ ✓ Hoạt độngPIC16F1507T-I/GZ Tóm tắt
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that combines a CPU, non-volatile program memory, RAM, and peripherals on a single die. The PIC16F1507 belongs to the broader PIC16 family -> 8-bit microcontroller category -> microcontroller -> embedded processor hierarchy. Compared with 32-bit ARM Cortex parts, 8-bit MCUs trade raw throughput for deterministic latency, low cost, and ultra-low sleep current, which is why they continue to dominate simple sensing, lighting, and human-interface designs.
Key features include an internal 16 MHz high-precision oscillator that eliminates an external crystal in most applications, two Configurable Logic Cells (CLC) for hardware-state-machine glue logic, a Numerically Controlled Oscillator (NCO) for fine-frequency digital synthesis, and a Complementary Waveform Generator (CWG) for motor/lighting half-bridge drive. An integrated Temperature Indicator module provides on-die thermal monitoring without an external sensor, and the 25 mA I/O source/sink rating enables direct LED drive.
Architecturally, the Enhanced Mid-range core adds hardware-limited arithmetic, a wider instruction set, and tighter interrupt latency versus baseline PIC12/PIC16. Self-read/write Flash allows in-application firmware updates and EEPROM-style data logging without an external memory IC.
Typical applications include consumer white goods, LED lighting controllers, battery chargers, small appliance user interfaces, and low-cost sensor nodes where the ADC, NCO, and CLC peripherals replace discrete analog components.
When designing with this part, reserve the UQFN-20 exposed pad as the primary thermal path and stitch it to a ground copper pour of at least 1 cm square; configure the configuration words (CONFIG1/CONFIG2) for the internal 16 MHz HFINTOSC during prototyping, then validate with the calibrated LFINTOSC for sleep-mode current budgets.

Ứng dụng tiêu biểu
PIC16F1507T-I/GZ phù hợp cho 7 Áp dụngs: LED Lighting Controller, Battery Charger Controller, Small Appliance User Interface, Sensor Node / IoT Edge Device, Hobby / Maker Development Boards, Industrial Control Logic, Fan / Motor Speed Controller.
LED Lighting Controller
The PIC16F1507T-I/GZ fits LED lighting controllers because its 4 standalone PWM channels, 25 mA I/O source/sink rating, and Complementary Waveform Generator (CWG) can directly drive MOSFET half-bridges for dimmable white or RGBW LED strings. The internal 16 MHz HFINTOSC provides jitter-free PWM frequency without an external crystal, while the 12-channel 10-bit ADC reads ambient-light sensors and potentiometer dim inputs. Compared with discrete 555-timer designs, the 1507 removes the oscillator RC tuning, integrates thermal fold-back via the on-die Temperature Indicator, and shrinks the BOM to one IC.
Được đề xuất
Battery Charger Controller
The PIC16F1507T-I/GZ fits cost-sensitive Li-ion / NiMH charger designs where the 10-bit ADC monitors battery voltage and current, the NCO generates precise PWM for synchronous-rectifier control, and the CLC blocks implement hardware-level charge-state logic without burning CPU cycles. Flash self-read/write lets the charger store custom charge profiles, while the 128 B EEPROM retains cycle-count and fault logs across power cycles. The industrial -40C to +85C grade covers consumer and light-industrial chargers and matches typical charge-temperature windows.
Được đề xuất
Small Appliance User Interface
The PIC16F1507T-I/GZ fits small-appliance HMIs - coffee makers, blenders, toaster ovens - because its 25 mA I/O drives LED indicators and 7-segment displays directly, the 12-channel ADC reads keypad matrices and thermistor inputs, and the integrated Temperature Indicator enables overtemperature shutdown without a separate sensor. The Enhanced Mid-range core's deterministic interrupt latency keeps capacitive-touch button response below 50 ms. Combined with a 3.5 KB Flash budget, this device replaces legacy PIC16F505 designs with much richer firmware in the same UQFN-20 footprint.
Được đề xuất
Sensor Node / IoT Edge Device
The PIC16F1507T-I/GZ fits simple IoT edge nodes where cost and sleep current dominate. Its 8-bit core, integrated ADC, and small Flash footprint let a battery-powered sensor sleep for months between readings, while the PIC16F1507T-I/GZ's PIC16 instruction set keeps firmware small and deterministic. Two CLC blocks implement hardware event filtering (e.g., wake-on-pulse) without CPU involvement, dramatically reducing average current. For wireless connectivity, an external sub-GHz or BLE module such as the MRF24J40 family can be SPI-attached.
Được đề xuất
Hobby / Maker Development Boards
The PIC16F1507T-I/GZ fits low-cost educational and hobby development boards such as Microchip's Curiosity platform because the UQFN-20 (GZ) package has the small footprint needed for compact demo boards while exposing 12 I/O for breadboard-friendly pin headers. Its internal 16 MHz oscillator, MPLAB X IDE support, and rich peripheral set make it a strong teaching example for ADC, PWM, and CLC concepts. The 3.5 KB Flash is large enough for sample code demonstrating interrupt-driven designs but small enough to be fully understood by students.
Được đề xuất
Industrial Control Logic
The PIC16F1507T-I/GZ fits industrial control logic blocks - relay drivers, solenoid multiplexers, valve controllers - where its 25 mA I/O directly drives optocouplers and low-side FETs, and its 12-channel ADC reads 4-20 mA loops through external shunts. The CWG module generates complementary PWMs for H-bridge motor direction control on small DC pumps or fans, and the industrial -40C to +85C grade handles factory-floor environments. Microchip's MPLAB X ecosystem and XC8 compiler enable IEC 61508 functional-safety paths for low-risk subsystems.
Được đề xuất
Fan / Motor Speed Controller
The PIC16F1507T-I/GZ fits small DC fan and motor speed controllers because the Complementary Waveform Generator (CWG) outputs dead-band-controlled complementary PWMs ideal for driving N-channel/P-channel MOSFET half-bridges. The 10-bit ADC reads back-EMF or tachometer pulses for closed-loop RPM control, and the NCO can synthesize a fine-frequency dither signal to spread EMI. Compared with a discrete 555 + op-amp design, the 1507 reduces part count, adds programmable acceleration/deceleration curves, and stores last-set RPM in EEPROM.

Ghi chú thiết kế
Estimated: at 20 MHz instruction rate and typical 8 mA active I_DD for the PIC16F1507, the UQFN-20's thermal pad must be soldered to a ground copper pour of at least 1 cm squared to keep theta_JA low. UQFN packages rely almost entirely on the exposed pad for heat removal - if the pad is left floating, junction temperature can rise 20-30 C above ambient at full CPU load, reducing long-term reliability. Stitch vias through the pad to the inner ground plane for best thermal performance.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 16) with the ground return via placed within 2 mm. For designs with high-current I/O switching (e.g., 25 mA LED drive), add a 10 uF bulk capacitor near VDD to suppress switching transients. The UQFN-20 land pattern requires NSMD (non-solder-mask-defined) pads for reliable paste release during assembly - review the Microchip UQFN-20 land-pattern application note before finalizing the PCB footprint.
Route the MCLR pin (RA3) away from high-current switching traces to avoid spurious resets. If RA3 is not used as MCLR, configure it as an input-only GPIO. Use Microchip's recommended 100 nF capacitor on MCLR for ICSP programming reliability. Avoid placing the 32.768 kHz crystal traces (if used) parallel to switching I/O traces to prevent coupling. Place the ICSP header on the board edge or under-bump to enable in-circuit programming during prototyping.
Do not exceed the absolute maximum VDD of 5.5V; use the MCP1700 LDO or similar for USB/5V-supplied designs. Configuration words (CONFIG1, CONFIG2) must be explicitly set in source code - leaving them at default may disable the MCLR pin or select the wrong oscillator. The 12-channel ADC requires both ADCON0 and ADCON1 to be initialized before use; forgetting to set the channel-select bits is a common first-time-programming bug. Watch for read-modify-write hazards on PORTA when bit-banging.
Sleep current on the PIC16F1507T-I/GZ with the 16 MHz HFINTOSC disabled is in the low-microamp range (per Microchip datasheet DS40001586D), enabling years of battery life on a 3 V coin cell for sensor nodes. Use the CLC + NCO + CWG peripherals to wake the CPU only on edge events so the core spends most of its time in sleep. Avoid leaving floating analog inputs - they draw bias current and can corrupt ADC readings. Set unused I/O pins as outputs low to minimize supply current.
