PIC16LF1773-E/SS - 8-bit MCU, 7KB Flash, 32MHz, 28-SSOP | Microchip
MPN: PIC16LF1773-E/SS ✓ Hoạt độngPIC16LF1773-E/SS Tóm tắt
An 8-bit microcontroller (MCU) is a small computing system-on-chip that integrates a CPU, program memory (Flash), data memory (RAM), non-volatile storage (EEPROM), and a configurable set of peripherals on a single die. The PIC16F family uses a modified Harvard RISC architecture with a 14-bit instruction word optimized for deterministic execution and very low power consumption, sitting within the broader hierarchy of MCU -> microcontroller -> embedded processor -> semiconductor.
Key features include an operating voltage range of 1.8V to 3.6V (LF variant for low-voltage / battery applications), internal oscillator up to 32MHz, 25 I/O pins, 4 x 10-bit ADC, 1 x 10-bit DAC, multiple 8-bit/10-bit timers, enhanced PWM, complementary waveform generators, zero-cross detect, and a hardware limit timer. The "E" suffix indicates the -40°C to +125°C extended temperature grade, suitable for industrial and automotive under-hood environments.
The PIC16LF1773 architecture pairs a 14-bit instruction pipeline with a rich analog front end, enabling functions such as digital power conversion, LED lighting control, motor drive, and battery management to be implemented with minimal external components. The XLP™ (eXtreme Low Power) technology provides nanoWatt deep-sleep modes (typically < 50 nA sleep current) suitable for energy harvesting and IoT battery nodes.
Typical applications include LED lighting drivers, switch-mode power supplies (digital SMPS), battery chargers, brushless DC motor control, sensor conditioning, and general-purpose low-power embedded control. The extended temperature grade makes it suitable for industrial automation, white goods, and certain automotive sub-system tasks.
When designing with this part, choose decoupling capacitors (100 nF + 1 µF) close to VDD/AVDD pins, and use the MPLAB X IDE with XC8 compiler for development. Configure unused I/O as outputs to minimize sleep current. Verify the brown-out reset and watchdog settings match the application's worst-case power profile.

Ứng dụng tiêu biểu
PIC16LF1773-E/SS phù hợp cho 6 Áp dụngs: LED Lighting Drivers, Switch-Mode Power Supply (SMPS) Control, Battery Charging & Battery Management, Brushless DC (BLDC) Motor Control, Sensor Signal Conditioning & IoT Edge Nodes, Industrial Automation & White Goods.
LED Lighting Drivers
The PIC16LF1773-E/SS is well suited to LED lighting driver designs thanks to its integrated 10-bit DAC, multiple 10-bit PWMs, complementary waveform generators, and zero-cross detect. Its 32 MHz core executes PID brightness loops with sub-microsecond latency, while the XLP nanoWatt sleep modes (under 50 nA) keep standby losses negligible in always-on fixtures. The 1.8V-3.6V VDD range allows direct battery or USB-powered driver topologies. Source current/sink current per I/O (25 mA) is sufficient to drive MOSFET gate drivers directly, simplifying the BOM. Engineers use the device for tunable-white, RGBW, and architectural lighting where high peripheral integration reduces part count.

Switch-Mode Power Supply (SMPS) Control
Digital SMPS designs benefit from the PIC16LF1773-E/SS's high-resolution PWM, programmable dead-band control, and 4 x 10-bit ADC for voltage and current feedback. Its 32 MHz instruction rate supports multi-loop digital control at 200 kHz+ switching frequencies with cycle-by-cycle current limiting. The integrated op-amps and comparators (CIP analog) close the feedback loop without external components, lowering BOM cost. The 28-SSOP package footprint fits compact DC-DC bricks and isolated POL converters. With 256 bytes of EEPROM, calibration constants and telemetry logs persist across power cycles.

Battery Charging & Battery Management
Battery charging applications exploit the PIC16LF1773-E/SS's low-voltage (1.8V-3.6V) operation, accurate ADC for current/voltage monitoring, and PWMs for buck/boost switching. The nanoWatt sleep modes are critical for solar or energy-harvesting nodes where quiescent current dominates efficiency. The 256-byte EEPROM stores learned battery parameters, charge cycle counts, and fault logs. The extended -40C to +125C temperature grade supports under-hood automotive and outdoor industrial deployments. With deterministic 14-bit instruction execution, the MCU can implement CC/CV charging profiles in firmware without external charger ICs.

Brushless DC (BLDC) Motor Control
The PIC16LF1773-E/SS drives BLDC motors via its 6-output complementary PWM module with programmable dead-band and fault shut-down inputs. Hardware timers trigger ADC conversions exactly synchronized to PWM edges, eliminating software jitter. The integrated op-amps condition back-EMF signals for sensorless commutation algorithms, while the 4 x 10-bit ADC samples phase currents. The 28-SSOP industrial/extended temp range supports appliance and small-fan applications. With 7 KB Flash, sensorless commutation algorithms fit comfortably and leave room for serial (UART/I2C/SPI) command interfaces.

Sensor Signal Conditioning & IoT Edge Nodes
IoT edge nodes benefit from the PIC16LF1773-E/SS's low sleep current, integrated 10-bit DAC for sensor excitation, and on-chip comparators for threshold detection. CIP peripherals can wake the CPU only when a sensor crosses a programmed limit, dramatically reducing average power. The 1.8V-3.6V range matches 2x AA / coin-cell battery topologies directly. UART, I2C, and SPI peripherals enable connectivity to external radios or sensors. The 28-SSOP package is footprint-compatible with many PIC16LF family alternatives, allowing memory upgrades without board redesign.

Industrial Automation & White Goods
The PIC16LF1773-E/SS extended temperature grade (-40C to +125C) qualifies it for industrial controllers, white goods, and certain automotive sub-systems. Its 25 I/O pins interface to keypads, displays, relays, and serial buses. The hardware limit timer and zero-cross detect are valuable for triac-based load control. With 7 KB Flash and 512 B RAM, the MCU executes appliance state machines (wash cycles, HVAC modes) without external memory. The 28-SSOP package is widely accepted in industrial designs due to its 5.30mm body width and compatibility with hand-solder rework.

Ghi chú thiết kế
The PIC16LF1773-E/SS operates from 1.8V to 3.6V on VDD with a separate AVDD/AVSS analog supply pair. Decouple both VDD and AVDD with a 100 nF ceramic capacitor placed within 5 mm of each pin, plus a bulk 1 µF to 10 µF. For ADC accuracy, tie AVSS to the same ground plane as VSS with a single point connection to avoid digital switching noise coupling into analog readings. The XLP nanoWatt sleep modes drop current below 50 nA typical with the watchdog disabled.
Configure all unused I/O pins as outputs (driven low) rather than inputs to minimize sleep current and prevent floating-pin oscillation. Do not exceed the absolute maximum VDD of 4.0V (per datasheet), even momentarily during power transients. For ICD debugging via PGC/PGD (RB6/RB7), ensure those lines are not assigned to user functions that would conflict with the debug tool. Brown-out reset should be enabled in configurations running from battery power to prevent code corruption at low VDD.
Estimated: at maximum CPU activity (32 MHz, full peripheral clock, all I/O toggling) the device draws approximately 8 mA at 3.6V. This yields a dissipation of roughly 29 mW. The 28-SSOP package's typical thermal resistance theta_JA is around 95 °C/W, giving a junction temperature rise of only ~3 °C above ambient - well within the -40 °C to +125 °C operating window. No heatsink or special copper pour is required for typical industrial use. Verify in-situ with a thermal probe during regulatory compliance testing.
Route the crystal traces (OSC1/OSC2) symmetrically and keep them short, with a ground guard ring around the crystal to minimize noise coupling. Place decoupling capacitors adjacent to each VDD/AVDD pin before any via to the power plane. The SSOP's 0.65 mm pin pitch is hand-solderable with a fine tip and good flux, but production assembly should use a stencil and reflow profile per JEDEC J-STD-020 (peak temperature 260 °C for matte-tin lead finish). Reserve a programming footprint (5-pin header for ICSP) even on production boards to allow post-assembly firmware update.
