PIC16LC620-04I/SS Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and peripheral interfaces on one die. Within the broader semiconductor taxonomy, the PIC16LC620 belongs to the microcontrollers > embedded ICs > integrated circuits hierarchy. Its RISC architecture and Harvard memory layout (separate program and data buses) allow most instructions to execute in a single instruction cycle, enabling deterministic real-time control. The LC variant specifically targets low-power applications where battery life is critical, distinguishing it from the standard C and upgraded A revisions.
Key features of the PIC16LC620-04I/SS include 35 instructions to learn (single-cycle, with the exception of two-cycle branches), 8-level hardware stack, 4 oscillator selection options (RC, LP, XT, HS), power-on reset, watchdog timer, power-saving SLEEP mode, and programmable code protection. The device also includes a comparator module and 13 I/O pins. Industrial temperature grade (-40C to +85C) supports operation in harsh environments.
The PIC16LC620-04I/SS architecture uses a 14-bit instruction word with separate 8-bit data path, allowing compact code density for state-machine and control-loop applications. The OTP program memory (One-Time Programmable) enables cost-effective low-volume production with programming performed at the factory or by the user with a device programmer. The 80-byte RAM supports small state tables and stack frames typical of motor-control and sensor-interface designs.
Typical applications include low-power battery-operated sensors, simple motor control circuits, automotive interior subsystems, industrial process controllers, white-goods control boards, and consumer appliance user interfaces. The 4 MHz clock and 200 ns instruction cycle suit timing-sensitive tasks such as PWM generation, event counting, and basic serial communication.
When designing with this device, plan for OTP programming (one-time only, no field re-programming) - use PIC16F series equivalents for development flexibility. The SSOP-20 footprint is the same as the PIC16C620 family, enabling PCB layout reuse across temperature grades and process variants.

Typische Anwendungen
PIC16LC620-04I/SS ist geeignet für 6 Anwendungs: Low-Power Battery Sensor Nodes, Simple PWM Motor Control, Consumer Appliance User Interface, Industrial Process Controller, Automotive Interior Subsystems, White Goods Control Boards.
Low-Power Battery Sensor Nodes
The PIC16LC620-04I/SS fits low-power battery sensor nodes because its LC designation delivers 2.5V minimum VDD operation with reduced quiescent current versus standard PIC16C620, allowing 2x AA alkaline cells to power the design. Its 4 MHz clock and 200 ns instruction cycle execute periodic sensor-sampling loops in just a few microamps of average current. The 13 GPIO pins accommodate digital I/O for switch inputs, LED indicators, and one-wire or I2C sensor interfaces via bit-banging. With only 80 bytes of RAM, firmware must be compact - but the 896-byte OTP program memory easily fits state-machine-style sampling code. Designers should use the SLEEP mode aggressively between samples to extend battery life to multi-year runtime.
Empfohlen
Simple PWM Motor Control
The PIC16LC620-04I/SS handles simple PWM motor control via its 13 GPIO pins configured as timer-driven outputs, suitable for small DC fans, solenoid drivers, or low-current stepper coils. With a 4 MHz instruction cycle, the device can generate PWM frequencies up to about 20 kHz with 8-bit duty resolution - sufficient for brushed DC motor speed control. The hardware watchdog timer catches firmware stalls that could otherwise leave a motor energized indefinitely. For three-phase BLDC, a PIC16F628 with USART and PWM peripheral is preferred; the LC620 suffices for brushed or unipolar stepper designs. The industrial -40C to +85C temperature range supports automotive under-hood or factory-floor deployments.
Empfohlen
Consumer Appliance User Interface
The PIC16LC620-04I/SS is well-matched to consumer appliance user interface boards - washing machine control panels, microwave keypads, and dishwasher displays - where it scans up to 13 button/LED matrix pins, debounces inputs, and drives 7-segment or LED indicators. Its 4 MHz clock processes keyscan loops in microseconds with negligible CPU load. The 80-byte RAM accommodates a small display buffer and mode state machine, while 896 bytes of OTP program memory holds the entire menu logic. The SSOP-20 footprint saves board space versus PDIP equivalents. Industrial temperature grade is appropriate for kitchen environments where internal temperatures can exceed 70C near heating elements.
Empfohlen
Industrial Process Controller
The PIC16LC620-04I/SS suits industrial process controllers requiring deterministic timing at 2.5V to 6.0V supply, including PLC digital input cards, conveyor sorters, and packaging machine actuators. Its built-in watchdog timer and brown-out reset provide field-reliable operation in electrically noisy factory environments. The on-chip comparator module enables analog threshold detection without an external op-amp, saving board space. With 35 single-cycle instructions, the LC620 executes deterministic control loops at sub-microsecond resolution. For new industrial designs, the flash-based PIC16F628-I/SS in the same SSOP-20 footprint is recommended for firmware update capability.
Empfohlen
Automotive Interior Subsystems
The PIC16LC620-04I/SS operates from 2.5V to 6.0V which aligns with 5V automotive body electrical rails, and the industrial -40C to +85C temperature range handles cabin environments. Suitable applications include HVAC mode controls, seat position memory switches, and interior lighting controllers. The watchdog timer ensures recovery from electrical transients on the 12V battery rail. With 13 I/O pins, the LC620 can scan button matrices, drive relay coils, and read back switch position feedback. For under-hood or AEC-Q100 qualified designs, choose PIC16F627-I/SS or PIC16F628-I/SS flash parts in the same SSOP-20 package for automotive-grade qualification.
Empfohlen
White Goods Control Boards
The PIC16LC620-04I/SS is a typical choice for white goods like washing machines, dryers, and dishwashers where its 13 GPIO pins drive relay coils, read thermistor NTC voltages via the comparator module, and interface with encoder knobs. With 896 bytes of OTP, control firmware including cycle state machines, fault detection, and user menu logic fits comfortably. The industrial -40C to +85C rating handles the wide temperature swings near heating elements. Engineers designing modern white goods with firmware update capability should consider the PIC16F628-I/SS as a drop-in flash replacement sharing the SSOP-20 footprint and pinout.

Wichtigste Unterscheidungsmerkmale
- Low-voltage operation down to 2.5V vs 3.0V on standard C620A (vs. PIC16C620A-04I/SS)
- Flash reprogrammability vs OTP one-time programmable (vs. PIC16F627-04I/SS)
- Same-die LC620 family with extended temperature range option (vs. PIC16LC620-04E/SS)
Designhinweise
PIC16LC620 uses One-Time Programmable (OTP) EPROM - any firmware bug means a new chip is required for every production unit, with no possibility of field updates. Plan development carefully: prototype with PIC16F627 or PIC16F628 flash equivalent in the same SSOP-20 footprint, validate firmware, then port to the LC620 OTP for production. Avoid using all 80 bytes of RAM - leave at least 16 bytes headroom for stack depth during interrupt servicing.
Place the 20-SSOP decoupling capacitor (100 nF ceramic) within 5 mm of the VDD pin 20 with a low-inductance trace to the nearest VSS pin (5, 14, or 19). For battery-powered designs using the LC variant, add a 10 uF bulk capacitor near the IC to handle motor or relay inrush. Avoid routing noisy digital signals (PWM, relay coil drive) under the IC package to prevent coupling into the OSC1/OSC2 oscillator pins.
The LC620 supports 2.5V to 6.0V operation; ensure your power supply stays within this range during all transients including motor back-EMF. Add a TVS diode or Zener clamp on VDD if the design drives inductive loads. The brown-out reset and power-on reset are factory-trimmed; consult the configuration bits to enable BOD at the appropriate threshold (typically 2.5V for 3.3V systems or 4.5V for 5V systems). SLEEP mode reduces current to single-digit microamps - use it aggressively between sampling events to extend battery life.
Compliance-Informationen
Legacy Microchip OTP part typically ships with SnPb finish on SSOP leads, making it non-RoHS for EU markets. For RoHS-compliant designs in the same SSOP-20 footprint, choose PIC16F627-I/SS or PIC16F628-I/SS flash equivalents. Not AEC-Q100 qualified - for AEC-Q100 automotive requirements, consider PIC16F15344-I/SS or PIC16F18324-I/SS.
