PIC16LC62BT-04I/SO - 8-Bit 4MHz OTP MCU, 28-SOIC | Microchip
MPN： PIC16LC62BT-04I/SO ✓ 啟用中PIC16LC62BT-04I/SO 概覽
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU, program memory, data RAM, and peripherals on one die. The PIC16LC62B is part of Microchip's mid-range PIC16 family, sitting within the broader taxonomy of microcontroller -> embedded controller -> semiconductor device. These MCUs excel in cost-sensitive embedded control applications where deterministic instruction execution and low power consumption matter more than raw throughput.
Key features include a 35-instruction RISC architecture with single-cycle execution (except program branches, which take two cycles), 200ns instruction cycle at 4MHz, integrated Brown-out Detect/Reset, Power-on Reset, PWM module, Watchdog Timer, and an industrial operating temperature range of -40C to +85C. The 'LC' suffix indicates the low-voltage CMOS variant optimized for 3V operation, while 'B' denotes the enhanced revision with more memory and 'T' indicates the tape-and-reel packaging. The 04 suffix marks the 4MHz speed grade.
The device uses a Harvard architecture with separate program and data buses, allowing instruction fetch and operand access to occur simultaneously. This architectural choice delivers predictable execution timing that simplifies real-time control loop design. The 22 I/O pins can be individually configured as digital input or output, with several pins multiplexed to the analog comparator, PWM, and serial peripheral interfaces.
Typical applications include consumer electronics remote controls, appliance control boards, sensor signal conditioning, low-cost motor control, and battery-powered instrumentation. The industrial temperature grade and EPROM-based program memory make it particularly suitable for legacy designs, replacement of older PIC16C62 units, and field-programmable low-volume production runs where the OTP windowing option is not required.
When designing with this MCU, ensure your programmer supports the 28-SOIC package variant or use an adapter socket. The internal RC oscillator option can reduce BOM cost by eliminating an external crystal, but the 04 speed grade specifies a 4MHz external clock input. Code compatibility with the PIC16C62 and PIC16F62 family simplifies firmware migration.

典型應用
PIC16LC62BT-04I/SO 適用於 6 應用s: Consumer Remote Control, Appliance Control Board, Sensor Signal Conditioning, Low-Cost Motor Control, Battery-Powered Instrumentation, Industrial Sensor Interface Module.
Consumer Remote Control
The PIC16LC62BT-04I/SO fits remote control designs where its 35-instruction RISC core, 200ns instruction cycle at 4MHz, and 22 I/O pins deliver responsive button-scanning and IR-LED modulation without external logic. With 3.5KB OTP, the MCU can store complex IR protocols like RC5/RC6 or NEC with checksum generation, while 128 bytes of RAM holds the state machine. Brown-out Detect prevents latch-up during battery insertion on coin-cell powered units, and the 3.0V to 5.5V range supports both alkaline and lithium chemistries directly. Compared to a 32-bit Cortex-M0 alternative, the PIC16LC62B uses roughly 1/10 the active current, extending battery life in always-on standby designs.
推薦
Appliance Control Board
In washing machines, dishwashers, and microwave oven control boards, the PIC16LC62BT-04I/SO drives multiplexed LED or LCD displays, reads keypad matrices, and generates PWM signals for motor speed or heater control. The integrated PWM module plus 22 I/O pins handle triac firing, relay switching, and sensor inputs (temperature, water level) on a single chip. The industrial -40C to +85C temperature grade tolerates kitchen and laundry-room thermal stress. Hardware Brown-out Reset and Power-on Reset ensure the appliance starts in a defined safe state after power interruption, and 3.5KB OTP is sufficient for the state-machine firmware without external memory.
推薦
Sensor Signal Conditioning
The PIC16LC62BT-04I/SO works well as a low-cost sensor signal conditioner for thermocouples, thermistors, RTDs, and bridge-type pressure sensors. Its analog comparator plus 22 digital I/Os allow software-implemented sigma-delta ADC with oversampling, achieving 12-bit effective resolution from a single comparator pin. With 3.5KB OTP and 128 bytes RAM, the firmware can implement linearization tables, EEPROM emulation (using internal program-memory writes), and UART-based sensor reporting. The 3.0V to 5.5V range accommodates both 3.3V digital sensors and legacy 5V analog front-ends without level shifters.
推薦
Low-Cost Motor Control
For small brushed-DC motors, solenoids, and valve actuators, the PIC16LC62BT-04I/SO generates the PWM output to drive MOSFET H-bridges or low-side switches directly from its I/O pins. The integrated PWM peripheral supports frequency and duty-cycle modulation with hardware auto-shutdown on fault inputs, simplifying BLDC commutation and current limiting. With 22 I/O pins, the MCU can read Hall sensors, encoder feedback, and end-stop switches while driving the power stage. The 4MHz clock provides 200ns instruction granularity for 50kHz PWM frequency, and the wide 3.0V to 5.5V supply range allows direct connection to 4-cell battery packs.

Battery-Powered Instrumentation
Handheld multimeters, portable data loggers, and field measurement instruments benefit from the PIC16LC62BT-04I/SO's low-voltage 3.0V operation and CMOS power efficiency. The LC process variant draws only microamps in sleep, and the integrated Watchdog Timer plus Brown-out Detect ensure reliable wake-from-sleep data acquisition. With 3.5KB OTP, the firmware can implement calibration constants, linearization, and simple text-based LCD driving routines. The 22 I/O pins interface to 4x4 keypad matrices, segment LCDs, and SPI-connected ADC front-ends for multi-channel measurement.
推薦
Industrial Sensor Interface Module
In factory automation, the PIC16LC62BT-04I/SO serves as a slave I/O expander or protocol converter, translating between 4-20mA analog loops, RS-485 links, and digital fieldbus networks. The I2C and SPI peripherals allow direct connection to sensor front-ends and EEPROM storage, while 22 I/O pins drive status LEDs, relay outputs, and optocoupler inputs. With the industrial -40C to +85C temperature grade, the module operates in unheated control cabinets. The 3.5KB OTP hosts Modbus RTU or proprietary protocol stacks, making this MCU a versatile bridge between legacy 4-20mA instrumentation and modern digital control networks.

設計說明
Place a 100nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 20) with the ground return tied directly to the VSS pin (pin 19) to minimize supply inductance. For applications with significant digital switching noise, add a 10uF tantalum or electrolytic bulk capacitor near the MCU. Keep the MCLR/VPP trace short and avoid routing it near PWM or high-frequency signals to prevent inadvertent reset during switching transients.
Do not exceed the absolute maximum VDD of 7.0V or apply voltage to any pin before VDD is powered, as the PIC16LC62B uses EPROM technology that can latch up. Ensure MCLR is pulled high through a 10k resistor and not left floating, otherwise spurious resets will occur. For ICSP programming, isolate the MCLR pull-up from any large external capacitance, which can interfere with the high-voltage VPP programming pulse.
Route the OSC1/OSC2 (or RC oscillator) traces short and symmetrically to avoid stray capacitance that shifts the oscillator frequency. If using a high-Q crystal, keep the crystal traces within a ground guard ring and place load capacitors within 3mm of the MCU. For cost-sensitive designs using the internal RC oscillator, the calibration constant must be loaded from program memory at startup to compensate for voltage and temperature drift.
