PIC16C62A-10/SP - 8-Bit 10MHz OTP MCU 3.5KB | Microchip
MPN: PIC16C62A-10/SP ✗ انتهى عمره الإنتاجيPIC16C62A-10/SP نظرة عامة
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, and peripheral interfaces on one die. Within the broader semiconductor taxonomy, MCUs sit under microcontrollers, then embedded processors, then semiconductors. The PIC16C62A specifically belongs to Microchip's mid-range PIC16C family, which uses a 14-bit instruction word and Harvard architecture to deliver deterministic single-cycle execution for most instructions, making these parts a workhorse for cost-sensitive industrial and consumer control.
Key features of the PIC16C62A-10/SP include a 10 MHz maximum operating frequency (the "-10" speed grade), 22 general-purpose I/O pins, 128 bytes of data RAM, integrated I²C and SPI synchronous serial ports, a 10-bit-resolution capture/compare/PWM module, an 8-bit timer/counter, a watchdog timer with on-chip RC oscillator, brown-out reset, power-on reset, and an operating voltage range of 2.5 V to 6.0 V. The OTP program memory enables low-cost, one-time field programming for high-volume production runs.
Architecturally, the device separates program and data memory spaces (Harvard) and uses a 14-bit-wide instruction word with only 35 single-word instructions, simplifying code generation in assembly while supporting C compilers via Microchip's MPLAB XC8 toolchain. The high-performance RISC core executes most instructions in one instruction cycle (200 ns at 20 MHz, 400 ns at 10 MHz), and the 8-level hardware stack plus on-chip oscillator reduce external component count.
Typical applications for the PIC16C62A-10/SP include industrial control and sensor interfacing, automotive body and chassis subsystems, appliance motor control, low-cost remote sensor nodes, HVAC damper and valve control, and battery-powered instrumentation. Its combination of OTP memory, through-hole SPDIP package, and wide operating voltage makes it well suited to legacy designs and field-replaceable modules where socketed reprogrammability is not required.
When designing with this part, note that OTP memory cannot be erased, so firmware must be fully validated before programming. Programming voltage (typically 13 V on the VPP/MCLR pin) is required during device programming via Microchip's MPLAB PM3 or ICD tools. For new designs, Microchip designates the PIC16C62A as "Not Recommended for new designs" (NRND) and recommends the flash-based PIC16F62x family as the modern equivalent.

التطبيقات النموذجية
PIC16C62A-10/SP مناسب لـ 6 التطبيقs: Industrial Sensor Interfacing, Automotive Body and Chassis Control, Appliance Motor Control, Low-Cost Remote Sensor Nodes, HVAC Damper and Valve Control, Battery-Powered Instrumentation.
Industrial Sensor Interfacing
The PIC16C62A-10/SP suits industrial sensor interfaces that read analog and digital sensors, debounce switch inputs, and report data via I²C or SPI to a host controller. Its 10 MHz core provides 100 ns instruction cycle for fast polling loops, and 22 digital I/O lines support multiple sensor channels. Brown-out reset and watchdog timer improve field reliability. The 28-SPDIP package is socketable, simplifying field service.

Automotive Body and Chassis Control
The PIC16C62A-10I/SP variant (industrial -40°C to +85°C) and the PIC16C62A-10/SP support automotive body modules including seat controllers, mirror actuators, lighting drivers, and HVAC damper positioning. The integrated CCP/PWM module generates accurate servo drive signals; brown-out reset handles automotive load-dump conditions. For new automotive designs, however, Microchip recommends AEC-Q100-qualified dsPIC33 or PIC18 families rather than this NRND OTP part.
موصى به
Appliance Motor Control
The PIC16C62A-10/SP drives small universal and DC brushless motors in washing machines, dishwashers, fans, and small pumps. Its 10-bit CCP/PWM module generates variable-duty-cycle drive signals at frequencies up to 20 kHz, well above audible range for quiet operation. 22 I/O lines support direction, brake, tachometer, and protection signals. The 2.5-6.0 V supply range covers both 3.3 V logic and 5 V power stages.
موصى به
Low-Cost Remote Sensor Nodes
In remote sensor networks using SPI or I²C slave interfaces, the PIC16C62A-10/SP acts as a local data concentrator that reads sensors, performs averaging or threshold detection, and reports via synchronous serial port. The 128-byte RAM supports small circular buffers, and the 35-instruction RISC core keeps firmware compact. Low-cost OTP programming fits disposable or one-time-use sensor installations.
موصى به
HVAC Damper and Valve Control
Building HVAC systems use the PIC16C62A-10/SP to drive proportional damper actuators and valve stepper motors. The CCP module generates precise PWM signals for proportional control, while additional I/O lines read position feedback and end-stop switches. Brown-out reset protects against line-voltage brownouts, and the wide 2.5-6.0 V supply range accepts common 5 V and 3.3 V logic levels from HVAC controllers.
موصى به
Battery-Powered Instrumentation
Battery-powered measurement instruments such as portable multimeters, handheld data loggers, and field calibration tools use the PIC16C62A-10/SP for low-power control and display multiplexing. The CMOS process and low-frequency 32 kHz sleep-mode operation support multi-year battery life. The 22 I/O lines drive LCD segments, button matrices, and serial ports. Industrial-temp variants extend operation to outdoor environments.

ملاحظات التصميم
PIC16C62A uses OTP (one-time programmable) memory that cannot be erased. Always validate firmware on a flash-based equivalent (PIC16F628A-I/P) or windowed UV-erasable part (PIC16C62A-JW) before committing to the OTP device. Once programmed, an incorrectly programmed OTP device must be physically replaced. Allow for a programming voltage of approximately 13 V on the MCLR/VPP pin during device programming via Microchip's MPLAB PM3 or ICD tools.
The PIC16C62A-10/SP operates from 2.5 V to 6.0 V. Brown-out reset (BOR) is enabled by configuration fuse to reset the device when VDD drops below the BOR threshold, preventing code execution at low voltage. For battery-powered designs, disable the BOR via configuration bit to operate down to 2.0 V, but accept the risk of code corruption at low VDD. The PIC16C62A's CMOS design draws only microamps in sleep mode, making it suitable for battery applications.
The 28-SPDIP package is socketable, simplifying field service and in-circuit firmware updates during development. Place a 0.1 µF decoupling capacitor within 5 mm of the VDD pin (pin 12) and a bulk capacitor (1-10 µF) at the board's power entry. For the 28-SSOP variant (PIC16C62A-10I/SS), use a 4-layer PCB with ground plane to manage the reduced thermal mass. Crystal or ceramic resonator should be placed within 10 mm of OSC1/OSC2 (pins 8-9) with short traces to minimize EMI.
ICSP programming requires the PGC (RB6, pin 19) and PGD (RB7, pin 20) lines to be accessible in-circuit. Per Microchip's ICSP design guide, avoid large capacitive loads (>50 pF) on these pins and consider adding a 4.7 kΩ pull-up on MCLR/VPP. For low-voltage (3.3 V) ICSP programming, verify that the configuration bits are set for LVP (low-voltage programming) to avoid needing 13 V on VPP during development.
معلومات الامتثال
PIC16C62A-10/SP is a legacy OTP part originally released before RoHS-mandated lead-free compliance. The device uses SnPb lead finish. For RoHS-compliant designs, migrate to the PIC16F628A-I/P. AEC-Q100 qualification is not available; for automotive designs, use AEC-Q100-qualified PIC18 or dsPIC33 family.
