PIC16F1789-E/P - 8-Bit 32MHz 28KB Flash MCU | Microchip DIP-40
MPN: PIC16F1789-E/P ✓ Hoạt độngPIC16F1789-E/P Tóm tắt
What is an 8-bit Flash Microcontroller? An 8-bit MCU is a microprocessor-on-a-chip that processes data in 8-bit chunks and integrates Flash program memory, RAM, peripherals, and a CPU core in a single package. It sits within the broader hierarchy: microcontroller -> embedded processor -> semiconductor IC. The PIC16F1789 belongs to Microchip's PIC16F1xxx Enhanced Mid-Range family with 49 instructions, 16 stack levels, and self read/write Flash capability.
Key features of the PIC16F1789-E/P include a wide operating voltage range from 2.3V to 5.5V, four PSMC channels for advanced motor and power control, three operational amplifiers, and ultra-low-power XLP technology with deep sleep current as low as 20 nA typical. The device also offers 4x 12-bit ADC with 11 channels, 8-bit DAC output, and up to 36 I/O pins. Hardware peripherals include EUSART, I2C/SPI, two CCP, and Fast Comparator.
The architecture uses an Enhanced Mid-Range RISC CPU with a 14-bit instruction word and 16-level hardware stack. The integrated PSMC and op-amps reduce BOM cost by eliminating external analog components, while the XLP technology extends battery life in energy-harvesting and portable designs. Self-write capable Flash supports in-field firmware upgrades.
Typical applications include industrial sensor conditioning, BLDC/PMSM motor control with PSMC, LED lighting drivers, battery chargers, and IoT edge nodes. The combination of analog peripherals and digital logic makes it suited for closed-loop control and mixed-signal designs.
When designing with this part, ensure decoupling capacitors are placed close to VDD/AVDD pins and that the in-circuit serial programming (ICSP) interface pins are accessible for firmware updates.

Ứng dụng tiêu biểu
PIC16F1789-E/P phù hợp cho 6 Áp dụngs: BLDC Motor Control, LED Lighting Drivers, Industrial Sensor Conditioning, Battery Management Systems, IoT Edge Sensor Nodes, Smart Appliance Control.
BLDC Motor Control
The PIC16F1789-E/P is a strong fit for BLDC and PMSM motor control because it integrates four PSMC channels that generate complementary PWM with programmable dead-band, plus three on-chip op-amps for current sensing and back-EMF amplification. The 32 MHz CPU closes current/torque loops in tens of microseconds, while the 12-bit ADC samples phase currents synchronously to the PWM. Pin-to-pin replacement of legacy PIC16F1939 designs with on-chip PSMC and op-amps eliminates external gate-driver logic. The PIC16F1789-E/P adds active braking and hardware fault response without extra ICs.

LED Lighting Drivers
Tunable-white and RGBW LED drivers benefit from the PIC16F1789-E/P's four PSMC channels for high-frequency dimming and color-mixing PWM, plus 12-bit ADC for ambient-light and color-sensor feedback. The 8-bit DAC sets constant-current reference levels for buck/boost driver ICs. Operating voltage up to 5.5V simplifies USB-C or 5V supply rails. The XLP deep-sleep mode cuts standby power below 20 nA, meeting Energy Star and EU Ecodesign standby limits for connected luminaires.

Industrial Sensor Conditioning
Bridge sensor, strain-gauge, and thermocouple front-ends exploit the PIC16F1789-E/P's three op-amps configured as PGAs with the 12-bit ADC and 8-bit DAC for offset nulling. The EUSART and I2C peripherals transmit calibrated data to PLC or industrial-bus gateways. Extended -40C to +125C temperature supports outdoor and factory-floor deployments. The wide 2.3V to 5.5V supply range tolerates regulated 24V rails post-LDO. The same 40-pin PDIP footprint eases migration to surface-mount QFN-44 variants in volume.

Battery Management Systems
Lithium-ion pack monitoring and balancing rely on the PIC16F1789-E/P's 12-bit ADC for cell voltage measurement and 5-bit DAC for reference generation. The op-amps form cell-balancing current regulators, while PSMC channels drive synchronous buck converters for charging. XLP sleep current of 20 nA preserves pack charge during storage. The 28 KB Flash stores complex state-of-charge algorithms, and EEPROM retains cell history across power cycles. Drop-in compatibility with PIC16F1789-I/P simplifies regional qualification.

IoT Edge Sensor Nodes
Connected sensors for predictive maintenance and HVAC monitoring use the PIC16F1789-E/P's 12-bit ADC to digitize temperature, humidity, and pressure signals, then relay via I2C/SPI to a wireless module. XLP technology delivers multi-year battery life, and 28 KB Flash supports MQTT-SN or LoRaWAN stacks. The 32 MHz CPU handles local edge processing without external DSP. The 40-pin PDIP eases breadboard prototyping for makers and proof-of-concept before transitioning to the QFN-44 production variant.

Smart Appliance Control
Washing machines, dishwashers, and induction cooktops integrate the PIC16F1789-E/P for inverter control and user-interface processing. The PSMC channels drive induction coils or BLDC drums, the 12-bit ADC reads current and temperature, and the op-amps condition zero-crossing signals. EUSART links to Wi-Fi/BLE modules for app connectivity. The extended -40C to +125C grade survives appliance compartments. Pin compatibility with PIC16F1779-I/P and PIC16F1769-I/P simplifies platform variants.

Ghi chú thiết kế
Place a 100 nF decoupling capacitor as close as possible to each VDD/AVDD pin pair, and a bulk 10 uF tantalum or ceramic capacitor near the IC. The PIC16F1789-E/P's analog and digital supplies are independent: route AVSS to the ground plane through a star-point rather than daisy-chain. For applications using ADC at >100 kSPS, a ferrite bead between VDD and AVDD improves noise by 6-10 dB.
The 40-pin PDIP is ideal for breadboard and through-hole prototypes, but at production volume migrate to the QFN-44 variant PIC16F1789-E/ML to save board area. Both share the same pin mapping for port bits; the QFN adds ground pad that should be soldered to a 5x5 mm copper pour to meet thermal and electrical performance. Use 0402 or 0603 passives near QFN variant for compact layout.
Do not leave the MCLR/VPP pin floating: tie it to VDD through a 10 kohm resistor with a 100 nF cap to ground for noise immunity. When using the PSMC channels in complementary-PWM mode, ensure dead-band registers (PDCx) are non-zero to prevent shoot-through. The on-chip op-amps have limited output swing; for rail-to-true-rail operation use the DAC reference output. Always include ICSP header (PGC/PGD/VPP/VDD/VSS) on prototype boards for firmware updates.
The PDIP-40 package has theta_JA approximately 50 C/W in still air, dropping to 35 C/W with light airflow. At 32 MHz and 5.5V with all peripherals active, the device typically dissipates under 50 mW, so self-heating is negligible. Estimated: junction temperature rise is 2.5C at 50 mW dissipation, well below the 150C maximum. Industrial applications above 85C ambient still require verification of derated clock frequency per datasheet Figure 36-3.
