PIC16LC62A-04/SP 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, non-volatile data storage, and programmable I/O peripherals on one die. Within the Microchip taxonomy, the PIC16 series is a mid-range 8-bit RISC architecture using a 14-bit-wide instruction word, a small register file, a hardware stack, and a RISC instruction set designed for deterministic, low-MIPS embedded control. The 'LC' suffix indicates a low-voltage CMOS variant (as opposed to the higher-voltage 'C' or 'F' Flash family), making the PIC16LC62A a member of the power-management-optimized branch of the PIC16C sub-family.
Key features include 35 single-word instructions, a 200 ns instruction cycle at 4 MHz, a two-level deep hardware call/return stack, and seven or eight Special Function Registers (SFRs). Addressing modes cover direct, indirect, and relative, supporting efficient C and assembly code generation. The 22 I/O ports can be individually configured for digital input or output, with several pins multiplexed for timer, comparator, or external interrupt functions typical of PIC16C-series MCUs.
Typical applications span industrial automation controllers, sensor signal-conditioning front ends, appliance control boards, automotive body and chassis subsystems, and consumer white-goods embedded controls where a proven 8-bit core, OTP memory for low-cost unit production, and a DIP package for serviceability outweigh the need for in-system reprogrammability or higher analog integration. Designers valuing pin-compatibility with newer Flash-based PIC16F replacements can migrate without PCB rework. Lifecycle status is reported as ACTIVE by distributors, confirming continued availability for both new designs and long-life maintenance programs as of 2026-09-22.

일반적인 애플리케이션
PIC16LC62A-04/SP 적합 용도: 6 애플리케이션s: Industrial Sensor Interface Controller, Appliance Control Board, Automotive Body and Chassis Subsystem, Consumer Remote Control and IR Receiver, Educational and Hobbyist Embedded Platform, Legacy Maintenance and Field Replacement.
Industrial Sensor Interface Controller
The PIC16LC62A-04/SP is well-suited for industrial sensor interface boards where multiple digital sensors (limit switches, proximity sensors, encoders) must be polled and conditioned. Its 22 programmable I/O lines let the MCU read up to 22 discrete inputs directly, while the 4 MHz clock and 200 ns instruction cycle provide enough MIPS to debounce, count, and forward sensor state via UART or SPI. The 2.5 V to 6.25 V supply range accommodates both 3.3 V digital sensors and legacy 5 V industrial backplanes without level shifting. The OTP-EPROM program memory locks firmware at production, preventing accidental field reprogramming of safety-relevant logic. The 28-SPDIP package simplifies hand-soldered prototypes and field-serviceable control cabinets where through-hole replacement is preferred over SMD rework.
추천
Appliance Control Board
The PIC16LC62A-04/SP fits white-goods appliance control boards such as washing machines, dishwashers, and microwave oven user interfaces. The 22 I/O lines drive keypads, LED indicators, seven-segment displays, and relay coils, while the 35-instruction PIC16 RISC core executes timing, sequencing, and user-input state machines with deterministic 200 ns instruction cycles. The 3.5 KB OTP-EPROM holds full appliance firmware at low per-unit cost, since OTP parts are typically priced below Flash equivalents for high-volume production. The 2.5 V to 6.25 V supply lets the MCU share a rectified 5 V or 3.3 V rail with the appliance's power supply. The 28-SPDIP through-hole package survives the vibration and thermal cycling of consumer appliance environments.
추천
Automotive Body and Chassis Subsystem
The PIC16LC62A-04/SP is used in automotive body and chassis subsystems such as lighting controllers, HVAC blend-door actuators, and simple dashboard switch readers, where a small 8-bit MCU with 22 I/O lines, deterministic interrupt handling, and a wide supply range are sufficient. The PIC16 RISC core's 200 ns instruction cycle supports real-time debouncing of mechanical switches and PWM generation for LED dimming or motor speed control. The 3.5 KB OTP-EPROM locks the application firmware at production, preventing warranty-affecting field reprogramming. The 28-SPDIP package is favored for prototyping and aftermarket service, where through-hole parts are easier to field-replace than fine-pitch SMD. For under-hood modules requiring AEC-Q100 qualification and extended temperature, designers should pair this with an automotive-grade variant or migrate to PIC16F882-I/SP.
추천
Consumer Remote Control and IR Receiver
The PIC16LC62A-04/SP is well-matched to consumer IR remote controls, IR receiver base stations, and RF remote encoder boards that need a small 8-bit MCU with low power consumption and 22 flexible I/O lines. The LC CMOS core draws less operating current than the standard PIC16C variant, helping extend battery life in handheld transmitters. The 4 MHz clock is more than adequate for generating 38 kHz carrier modulation for IR or for decoding RC5/ NEC protocol frames in a receiver. The 3.5 KB OTP-EPROM stores protocol tables, button maps, and device pairing IDs without the per-unit cost overhead of Flash. The 28-SPDIP package is preferred for low-volume specialty remotes where hand assembly and through-hole rework dominate the bill of materials.
추천
Educational and Hobbyist Embedded Platform
The PIC16LC62A-04/SP is a popular educational and hobbyist embedded platform because the 28-pin SPDIP package fits standard 0.300 inch DIP sockets and breadboards, the 4 MHz clock supports straightforward timing tutorials, and the 35-instruction PIC16 RISC set is widely documented in textbooks and university curricula. Students can program the OTP-EPROM using low-cost PIC programmers and the MPLAB IDE, learning assembly and C embedded fundamentals on a mature, well-characterized architecture. The 22 I/O lines drive LEDs, buttons, seven-segment displays, character LCDs, and simple sensors without external multiplexers. The 2.5 V to 6.25 V supply tolerates either USB-powered 3.3 V or battery-powered 5 V lab supplies, making the part forgiving in classroom and maker settings where power rails are improvised.
추천
Legacy Maintenance and Field Replacement
The PIC16LC62A-04/SP is a critical maintenance and field-replacement part for installed industrial, appliance, and automotive controllers shipped in the late 1990s and early 2000s on the original PIC16C-series architecture. The OTP-EPROM and 28-SPDIP through-hole package were industry-standard at that time, so field service depots, repair shops, and aftermarket rebuilders stock this part for repairing out-of-warranty units where redesigning for a newer MCU is uneconomical. Microchip's ACTIVE lifecycle status as of 2026-09-22 confirms continued catalog availability, sparing maintenance engineers from forced PCB redesigns. The pin-compatibility with later Flash-based PIC16F882-I/SP also enables a low-risk migration path when legacy volume falls below OTP economic thresholds.

설계 노트
The PIC16LC62A-04/SP operates from 2.5 V to 6.25 V supply, supporting both 3.3 V and 5 V rails. Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk capacitor (>= 10 uF) at the board supply input. The LC CMOS core draws substantially less current than the standard PIC16C variant, so a low-dropout regulator is generally not required for the MCU rail - the supply can be tapped directly from the system rail. Always hold MCLR (pin 4) high through a 10 kohm pull-up for normal operation; pull MCLR low only for reset or programming.
For the 28-SPDIP package, route the oscillator pins OSC1 (pin 16) and OSC2 (pin 15) with short traces and keep them away from high-current switching nodes to minimize EMI coupling into the system clock. Use a 4 MHz ceramic resonator with built-in capacitors, or a crystal with two 22 pF load capacitors to GND. Port B and Port C pins are the primary digital I/O; reserve RB0 (pin 6) for the external interrupt input INT and configure it with a 10 kohm pull-up if used as a wake-up source.
PIC16LC62A-04/SP uses One-Time-Programmable EPROM, not Flash - once programmed, the code cannot be erased or rewritten. Do not use this part for prototypes that require iterative firmware updates; reserve it for production-bound designs where the firmware is locked at factory programming. The two-level hardware stack limits call nesting to two levels, so deeply nested subroutines must be flattened or rewritten iteratively to avoid stack overflow. The 35 single-word instruction set is upward-compatible with the wider PIC16 family but does not include hardware multiply - implement multiplication in software if required.
규정 준수 정보
Detailed compliance information (RoHS, REACH, lead-free, halogen-free) for PIC16LC62A-04/SP was not present in the verified distributor snippets and is set to 'unknown' rather than assumed. The 'LC' OTP-EPROM process is a mature, long-life Microchip product family. AEC-Q100 is not applicable for the standard PIC16LC62A-04/SP; choose automotive-qualified AEC-Q100 parts explicitly when designing under-hood automotive modules.
