PIC16LC620T-04E/SS Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory, and I/O peripherals. Within the semiconductor hierarchy, MCUs belong to the embedded computing category; the PIC16C sub-family uses a RISC-style Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and operand access. PIC16C devices run 35 single-cycle instructions and are programmed with a 14-bit instruction word, giving higher code density than typical 8-bit CISC cores. The OTP memory makes these parts one-time programmable, suited for production volumes where reprogrammability is not required.
Key features include an internal oscillator option, two 8-bit timers (Timer0 and Timer2) plus one 16-bit Timer1, a 4-channel 8-bit ADC on most PIC16LC620 variants, and a watchdog timer with on-chip RC oscillator for reliable reset behaviour. The device supports in-circuit serial programming via the ICSP interface, reducing manufacturing complexity. The wide 2.5V-6.25V supply range and CMOS process deliver low power consumption suitable for sleep-mode applications.
Typical applications include automotive body controllers (non-AEC-Q100 grades), industrial sensor interfaces, low-end consumer appliance control, security keypads, and small motor control. The 20-SSOP footprint also makes it suitable for space-constrained designs where a 20-pin SOIC variant (PIC16LC620T-04E/SO) is too large.
When designing with this device, ensure decoupling: place a 100 nF capacitor as close as possible to the VDD pin, and reserve the MCLR pin for a proper reset network. Note that the 'E' temperature suffix typically indicates an extended industrial temperature range suitable for harsher environments.

Aplicaciones típicas
PIC16LC620T-04E/SS es adecuado para 7 aplicacións: Automotive Body Controllers, Industrial Sensor Interfaces, Consumer Appliance Control, Security Keypad and Access Panels, Small Motor and Fan Control, Battery-Powered Remote Controls, LED Display and Sign Drivers.
Automotive Body Controllers
The PIC16LC620T-04E/SS fits automotive body controller applications such as seat controllers, mirror adjusters, and lighting drivers where deterministic 8-bit processing is sufficient and the 2.5V-6.25V supply range handles 12V automotive rails after pre-regulation. Its 13 GPIO pins are enough for relay drivers, switch inputs, and PWM outputs for LED dimming. The 4 MHz clock and 14-bit RISC instructions keep interrupt latency low (200 ns per instruction cycle), which is essential for responding to switch events in body-control networks. Compared with flash-based PIC16F alternatives, the OTP PIC16LC620T-04E/SS offers lower unit cost at high production volumes typical of automotive modules.
Recomendado
Industrial Sensor Interfaces
The PIC16LC620T-04E/SS is well-suited to industrial sensor interface modules where 4-20 mA loop transmitters, RTD signal conditioning, or simple limit-switch inputs need local intelligence. The 4 MHz clock and 80-byte RAM handle linearization math for thermocouples or thermistors, while the 13 GPIO pins accept multiple sensor channels plus status LEDs. The extended industrial temperature range ("E" suffix) supports factory-floor environments. Low-voltage operation down to 2.5 V enables battery-backed sensor nodes that need to remain functional during line-power interruptions.
Recomendado
Consumer Appliance Control
For cost-sensitive consumer appliances (coffee makers, microwave ovens, washing-machine user interfaces), the PIC16LC620T-04E/SS provides just enough performance at the lowest per-unit cost in the PIC16C family. Its 896 B OTP memory holds typical user-interface state machines and timer routines, while 80 bytes of RAM is sufficient for keypad scanning and 7-segment multiplexing. The OTP memory prevents firmware theft by competitors, a key advantage in high-volume consumer markets. The 20-SSOP package allows placement on space-constrained UI boards alongside the main appliance MCU.
Recomendado
Security Keypad and Access Panels
The PIC16LC620T-04E/SS is ideal for electronic-lock keypads, access-control panels, and alarm-system user interfaces. Its 13 GPIO pins can scan a 4x4 matrix keypad (8 lines) plus drive status LEDs and a buzzer (3 lines). The OTP memory protects the access-control firmware against reverse engineering. The 2.5V-6.25V supply range supports both battery-powered (3V coin cell or 2xAA) and mains-powered (regulated 5V) installations, while the extended industrial temperature range is required for outdoor access panels.
Recomendado
Small Motor and Fan Control
The PIC16LC620T-04E/SS handles small brushed-DC motor control in fans, pumps, and small appliances via PWM on Timer2 and direction control on a GPIO pin. The 4 MHz clock and 14-bit instructions execute PWM update routines within a few microseconds, well within typical 1 kHz PWM periods. Hall-sensor or back-EMF feedback is supported via the interrupt-on-change feature of PORTB. The OTP memory prevents unauthorized motor-tuning parameters from being read out, protecting OEM calibration IP.
Recomendado
Battery-Powered Remote Controls
The PIC16LC620T-04E/SS operates from a wide 2.5V-6.25V supply, making it ideal for battery-powered remote controls that use 2xAA, 2xAAA, or coin-cell batteries that drop in voltage over their discharge curve. Sleep-mode current at 2.5V is low enough for multi-year battery life in intermittent-use remotes. The 13 GPIO pins accommodate button matrices up to 4x4 plus an IR LED driver. The OTP memory locks in the IR protocol code (RC5, NEC, or proprietary) to prevent cloning by competitors.
Recomendado
LED Display and Sign Drivers
For small LED signs, scrolling-message displays, and indicator panels, the PIC16LC620T-04E/SS multiplexes 7-segment or dot-matrix LED arrays via Timer0 and Timer2 interrupts. Its 80 bytes of RAM store display buffers for up to 10 characters. The 4 MHz clock provides the timing resolution needed for smooth PWM-based LED brightness control. The 20-SSOP package fits on small display-driver PCBs that must fit behind narrow LED bezels. The OTP memory prevents competitors from reading the custom font tables or animation sequences.

Notas de diseño
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 14) and a 10 uF bulk capacitor near the supply input. The PIC16LC620T-04E/SS operates from 2.5V to 6.25V per verified data; at 5V operation, the brown-out detect (BOD) circuitry resets the device if VDD drops below the configured threshold, preventing code corruption. For battery-powered designs, place the MCU in sleep mode between sensor reads to reduce average current to microampere levels.
The 20-SSOP package has a 0.65 mm pin pitch, which is at the limit of standard SMT assembly processes. Use a stencil with adequate aperture size and ensure solder paste deposition is consistent. Keep the MCLR pull-up resistor (typically 10 kOhm) close to the MCLR pin (pin 4) to minimize noise coupling that could cause spurious resets. Route the oscillator traces (OSC1/OSC2, pins 16/15) short and symmetric, with a ground guard ring around the crystal to reduce EMI.
Do not exceed the 6.25V absolute maximum supply voltage - even brief transients above this limit will damage the OTP memory and latch-up the device. Ensure the MCLR pin is never left floating: use a 10 kOhm pull-up to VDD, or add a 100 nF capacitor to VDD for noisy environments. Note that OTP memory can be programmed only once: verify your firmware with a flash-based PIC16F equivalent (such as PIC16F88-I/SS) before committing to the OTP PIC16LC620T-04E/SS for production.
