PIC16C62A-20/SS 概述
An 8-bit microcontroller is a small, single-chip computer built around an 8-bit data bus and a RISC (Reduced Instruction Set Computer) core optimized for deterministic, low-latency embedded control. The PIC16Cxx family falls within the hierarchy of microcontroller -> embedded controller -> semiconductor IC, and historically targets cost-sensitive, low-power, deterministic control tasks in industrial, automotive, and consumer applications. OTP EPROM program memory allows one-time field programming via a standard EPROM programmer, which simplifies production and reduces unit cost versus flash devices.
Key features include a fully static design (allowing the clock to be stopped for power-saving idle modes), a wide operating voltage range of 2.5V to 6.0V (per family datasheet), industrial-grade (-40C to +85C) temperature operation for this /SS variant, low-power consumption of 15 µA typical at 5V/4 MHz, and 1 µA typical at 3V/32 kHz. Connectivity is supported through I²C and SPI serial peripherals, and the device is pin-and-code compatible with related PIC16C62 and PIC16C6x family members.
Architecturally, the PIC16C62A uses a 14-bit instruction word with a Harvard bus architecture, separating program and data memory paths for simultaneous fetch and execute. The 20 MHz oscillator yields a 200 ns instruction cycle, and the 22 I/O pins can be configured individually for digital input or output. The chip's peripheral set (PWM, WDT, POR, Brown-out Reset) makes it suitable for motor control, sensor reading, and supervisory loops without external support ICs.
Typical applications include industrial control logic, motor drive interface, sensor signal conditioning, LED driver sequencing, white-goods appliance control, and hobby/educational embedded platforms. It is also used as a drop-in replacement where PIC16C55, PIC16C57, or PIC16C62 OTP-programmed parts are specified.
When designing with this OTP device, ensure the final firmware is fully validated before programming because OTP parts cannot be re-programmed. Add a decoupling capacitor of 0.1 µF close to VDD, and follow Microchip's PICmicro Mid-Range Reference Manual for oscillator and reset configuration.

典型应用
PIC16C62A-20/SS 适用于 6 应用s: Industrial Control Logic, Motor Drive Interface, Sensor Signal Conditioning, LED Driver Sequencing, White-Goods Appliance Control, Hobby and Educational Embedded Platforms.
Industrial Control Logic
The PIC16C62A-20/SS fits industrial control logic boards because its 22 I/O pins drive relays, switches, and indicator LEDs without external I/O expanders, and the 20 MHz core handles 200 ns instruction cycles for fast deterministic control loops. The integrated Brown-out Detect/Reset and Power-on Reset ensure reliable startup in noisy 24V-derived 5V industrial rails. OTP EPROM program memory keeps unit cost low for high-volume machine control boards once firmware is finalized, making it ideal for programmable logic controllers, conveyor controllers, and sensor interface boards where price dominates over re-programmability.
推荐
Motor Drive Interface
The PIC16C62A-20/SS suits motor drive interface boards because its PWM peripheral generates variable-duty drive signals for DC motor speed control, and its 22 I/O pins can read encoders, limit switches, and current-sense signals. The 20 MHz clock provides tight control loop timing, while OTP EPROM ensures the firmware cannot be accidentally overwritten by voltage transients common on motor power buses. The SSOP-28 surface-mount package fits compact BLDC driver boards, and the wide 2.5V-6.0V supply range accepts standard 5V motor logic rails without regulation. Designers should add flyback diodes on all PWM outputs to protect against inductive kickback.
推荐
Sensor Signal Conditioning
The PIC16C62A-20/SS is well-suited to sensor signal conditioning boards where the MCU reads analog or digital sensors, applies calibration, and outputs formatted data via I²C or SPI. The integrated I²C and SPI peripherals directly interface with temperature sensors, accelerometers, and EEPROMs, while the 22 I/O pins handle discrete sensor flags and status LEDs. OTP EPROM program memory provides tamper-resistance for calibrated production units, and the 128-byte RAM is sufficient for small sensor data buffers. Use the Watchdog Timer to recover from sensor bus lockups in unattended field deployments.
推荐
LED Driver Sequencing
The PIC16C62A-20/SS fits LED driver sequencing applications because its PWM outputs drive multiple LED channels at varying brightness levels and its 20 MHz clock supports complex chase and fade patterns. The 22 I/O pins can individually control status LED arrays, RGB channels, and seven-segment displays without external driver ICs. The low-power 15 µA typical current at 5V/4 MHz keeps idle sequencer power low, and the SSOP-28 footprint is small enough for compact signage controller PCBs. OTP memory locks the final lighting pattern against accidental field reprogramming.
推荐
White-Goods Appliance Control
The PIC16C62A-20/SS is appropriate for white-goods appliance control boards including washing machines, dishwashers, and microwave oven interfaces. Its integrated Brown-out Detect handles power dips during motor inrush, and the Watchdog Timer recovers from firmware lockups in harsh electrical environments. The 22 I/O pins drive seven-segment displays, keypad matrices, and relay control outputs, while PWM modulates motor speed or heater elements. OTP EPROM keeps per-unit cost low for high-volume appliance production runs, and the wide 2.5V-6.0V supply tolerance accepts unregulated rectified mains-derived rails.
推荐
Hobby and Educational Embedded Platforms
The PIC16C62A-20/SS is a classic educational microcontroller used in PIC training kits, university embedded systems courses, and DIY hobby projects. Its 14-bit mid-range instruction set is well-documented in the Microchip PICmicro Mid-Range Reference Manual, and the 28-pin SSOP package is easy to breadboard with breakout adapters. The 20 MHz clock, 22 I/O pins, and I²C/SPI peripherals cover the full range of beginner projects from LED blinking to sensor interfacing and serial communications. OTP EPROM makes it ideal for take-home student projects where final code must be locked.

设计说明
Add a 0.1 µF ceramic decoupling capacitor as close as possible to the VDD pin (pin 23/24 on the SSOP-28) and a bulk 10 µF tantalum or electrolytic capacitor on the supply rail. The PIC16C62A draws 15 µA typical at 5V/4 MHz and 1 µA typical at 3V/32 kHz per the family datasheet; ensure the supply can deliver peak current during ADC and I/O switching without sagging.
Because this is an OTP (One-Time-Programmable) EPROM device, the firmware cannot be erased or re-programmed once written. Always validate the firmware on a windowed or flash-equivalent development part (e.g., PIC16F62x family) before committing to OTP programming. EPROM programming requires the MCLR/VPP pin to be raised to VPP (~13V) - verify your programmer supports the PIC16C62A OTP algorithm.
Place the external oscillator crystal or resonator within 1 cm of the OSC1/OSC2 pins (pins 25/26) and route the oscillator traces symmetrically with a ground guard ring to reduce EMI coupling. Keep high-current PWM traces (CCP1 on RC2) short and away from analog sensor inputs on RA0-RA5 to minimize digital switching noise injection into ADC conversions.
Estimated: At 20 MHz and 5V supply, the PIC16C62A-20/SS typical core current is approximately 5-10 mA. With VDD = 5V, estimated power dissipation is 25-50 mW - well within the SSOP-28 thermal limits without a heatsink, even at the upper commercial temperature range. No thermal management is required for typical embedded applications.
合规信息
Lifecycle is obsolete per Microchip product status; original OTP EPROM parts predate modern RoHS/REACH compliance disclosures. Compliance status not confirmed in available data - request a certificate of compliance from the distributor when ordering legacy stock.
