PIC16LC62B-04/SP Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer containing a CPU, program memory (ROM/EPROM/Flash), data memory (RAM), and configurable I/O peripherals on one die. Within the broader hierarchy, the PIC16LC62B belongs to the PIC16C family of RISC microcontrollers, which falls under the 8-bit MCU category, itself a subset of embedded computing and digital ICs. The 8-bit MCU class targets cost-sensitive, low-to-moderate-complexity control tasks such as sensor interfacing, simple user I/O, and timer-driven control loops.
Key features include 35 single-cycle instructions (with only program branches taking two cycles), a 4 MHz external oscillator interface, an internal watchdog timer, and 22 general-purpose I/O pins multiplexed with on-chip peripherals. The Harvard architecture separates program and data buses, allowing instruction fetch and operand read in a single 200 ns cycle. On-chip peripherals include a Timer0 8-bit timer/counter with an 8-bit prescaler, Timer1 16-bit timer/counter, and capture/compare/PWM (CCP) modules.
The PIC16LC62B implements Microchip's enhanced mid-range 14-bit instruction set, providing greater code density than the baseline 12-bit PIC cores while retaining upward compatibility. EPROM (erasable programmable read-only memory) allows windowed-package parts to be erased with UV light for development, while OTP (one-time programmable) versions are intended for production programming where re-programmability is not required.
Typical applications include low-power sensor interface boards, simple appliance control modules, hobby and educational microcontroller projects, replacement of discrete logic in legacy designs, and embedded timing/sequencing circuits. The wide 3.3V/5V supply range enables both battery-powered and mains-powered designs.
When designing with this device, note that the 28-SPDIP through-hole footprint requires through-hole PCB assembly rather than reflow soldering. Programming requires a Microchip device programmer (e.g., PICkit or MPLAB PM3) and the OTP variant can only be programmed once.

Aplicações típicas
PIC16LC62B-04/SP é adequado para 6 aplicaçãos: Low-Power Sensor Interface Boards, Simple Appliance Control Modules, Hobby and Educational Microcontroller Projects, Replacement of Discrete Logic in Legacy Designs, Embedded Timing and Sequencing Circuits, Industrial Control Logic Modules.
Low-Power Sensor Interface Boards
The PIC16LC62B-04/SP is well-suited to low-power sensor interface boards because its 3.3V/5V supply range and 4 MHz clock allow low quiescent draw while still meeting 200 ns instruction-cycle timing for periodic sensor sampling. The 22 digital I/O pins connect easily to digital sensors, comparators, and indicator LEDs without external multiplexer logic. Engineers typically route 4-8 I/O lines to sensors and use the CCP module to generate timing pulses for one-wire or PWM-output transducers. Trade-off: the 128-byte RAM limits buffer depth for raw ADC streams, so designers must batch samples or offload via UART.
Recomendado
Simple Appliance Control Modules
The PIC16LC62B-04/SP fits simple appliance control modules - washing machine timers, microwave keypads, fan speed controllers - where 22 I/O pins can drive 7-segment displays, keypads, relays, and triac interfaces simultaneously. Its 3.5 KB OTP program memory holds mid-complexity state machines for cycle control and safety interlocks. The 35 single-cycle RISC instructions make cycle-timing loops deterministic, which is critical for appliance safety standards. Designers pair this MCU with opto-isolated triac drivers (e.g., MOC3041) on the AC side and a small EEPROM for user settings.
Recomendado
Hobby and Educational Microcontroller Projects
The PIC16LC62B-04/SP is a classic teaching vehicle in university embedded-systems courses because the 28-SPDIP through-hole package fits breadboards and 0.1-inch perfboards without SMD soldering. Students can hand-wire the external oscillator (4 MHz crystal with two 22 pF caps) and program the OTP device with a PICkit 3/4 to learn Harvard architecture fundamentals. Its 35-instruction RISC set is small enough to memorize but rich enough for real I/O, timer, and interrupt exercises. Trade-off: with modern curricula favoring PIC16F or PIC18F parts, this OTP device is best for retro-curriculum or inventory-clearance lab kits.
Recomendado
Replacement of Discrete Logic in Legacy Designs
The PIC16LC62B-04/SP is often used as a single-chip replacement for legacy designs built from 74-series TTL/CMOS glue logic, where 22 I/O pins can absorb 10-20 discrete gates, latches, and counter packages. With 3.5 KB OTP and 128-byte RAM it can implement state machines, frequency dividers, debouncers, and timed-sequence controllers in firmware. The 4 MHz clock and 200 ns cycle time are fast enough to emulate 1-2 MHz legacy logic in software. Compared to discrete-logic rebuilds, this part reduces PCB area by 50-70% and BOM count by an order of magnitude.
Recomendado
Embedded Timing and Sequencing Circuits
The PIC16LC62B-04/SP suits timing and sequencing circuits that previously used 555 timers, CD4541, or discrete RC networks. Its Timer0 (8-bit with prescaler) and Timer1 (16-bit) modules generate programmable delays from microseconds to minutes, and the CCP module produces PWM or compare-match triggers. The 22 I/O lines drive sequencer step relays, indicator LEDs, and interlock chains for industrial timers. Designers use the watchdog timer for failsafe operation and the power-on reset for deterministic startup in mission-timing modules.
Recomendado
Industrial Control Logic Modules
The PIC16LC62B-04/SP fits industrial control-logic modules where deterministic GPIO state machines replace PLC-style ladder logic for low-cost sub-systems. The 3.3V/5V supply and external-oscillator design accommodate noisy factory environments when paired with optocouplers and TVS protection. Its 22 I/O pins handle digital inputs from limit switches and outputs to relay drivers, with the CCP module generating PWM for proportional valves or indicator dimming. Trade-off: for safety-rated industrial systems (SIL/PL), engineers must add external watchdogs and dual-channel I/O; this OTP MCU alone cannot meet functional-safety standards.

Notas de projeto
Estimated: at 4 MHz clock and 5V supply, the PIC16LC62B typical active current is approximately 2-5 mA depending on peripheral activity. Add a 100 nF decoupling capacitor within 5 mm of the VDD pin and a bulk 10 uF electrolytic on the supply rail. The /MCLR pin requires a 10 kohm pull-up to VDD and a 100 nF capacitor to ground for brown-out protection. Without these components the MCU may enter undefined reset states on power-up.
The 28-SPDIP through-hole package requires 0.1-inch (2.54 mm) pitch through-hole pads and 0.6-0.8 mm drill holes. Keep the oscillator traces (OSC1, OSC2) shorter than 20 mm and route them away from high-current traces to minimize EMI coupling. Add a guard ring around the analog inputs (RA0-RA5) if connecting to analog signals, and place a ground pour beneath the MCU to reduce thermal gradient and provide low-impedance return paths.
Do not confuse the OTP (one-time programmable) PIC16LC62B with Flash-based PIC16F or PIC18F siblings - the OTP variant cannot be erased and re-programmed. Engineers debugging firmware should buy CERDIP windowed packages (PIC16C62B-04/JW) for development. Also note: the analog inputs (RA0-RA5) share pins with digital I/O and require explicit TRIS/ANSEL configuration before ADC reads; leaving them as digital inputs can damage the analog source if driven above VDD.
The external 4 MHz crystal oscillator needs two 15-33 pF load capacitors (typical 22 pF) placed within 5 mm of the OSC1 and OSC2 pins. For higher-noise environments, use a four-pin crystal module with built-in capacitors rather than a discrete two-pin crystal. The CLKOUT output on OSC2 can drive other PIC devices in a master-slave configuration but should be buffered if it drives more than one slave to avoid signal degradation.
