PIC16C62A-10/SO Overview
A PIC16C6x-series 8-bit microcontroller is a RISC-based embedded controller built on low-power, high-speed CMOS EPROM/ROM technology. It belongs to the broader product family hierarchy microcontroller -> MCU -> embedded IC -> semiconductor, and is intended for applications that need deterministic instruction execution, low power draw, and a small instruction footprint. The PIC16C6x family is typically used in commercial, industrial, and extended-temperature equipment where OTP (one-time-programmable) memory is acceptable.
Key features of the PIC16C62A-10/SO include a wide operating voltage range of 2.5 V to 6.0 V, with typical low-power consumption figures of 15 µA at 5 V/4 MHz and 1 µA at 3 V/32 kHz. The device is a fully static design and supports an external oscillator. Its 28-pin SOIC outline is compatible with industrial surface-mount manufacturing, and the 22 I/O pins provide ample flexibility for digital interfacing, keypad scanning, LED driving, and parallel bus applications.
The PIC16C62A-10/SO uses a Harvard RISC core with a small instruction set optimized for C and assembly compilers. The 10 MHz clock combined with the PIC instruction pipeline yields roughly 5 MIPS of throughput, which is sufficient for control loops, simple sensor fusion, and human-machine interface logic. The EPROM-based program memory enables factory-programmed, high-volume, low-cost designs.
Typical applications include industrial control logic, appliance control boards, automotive subsystems (non-safety), consumer electronics, security and alarm panels, and low-power sensor read-out systems. Designers choose this part for legacy 8-bit firmware reuse, OTP cost advantages, and the broad availability of PIC development tools.
A primary design consideration is OTP memory: once programmed, the PIC16C62A-10/SO cannot be re-flashed in-circuit. For iterative development, prototype using a windowed or flash sibling (such as PIC16F62x) and migrate to PIC16C62A-10/SO for production. Also confirm whether the part is still recommended for new designs versus mature/legacy use.

Typical Applications
PIC16C62A-10/SO is suitable for 6 applications: Industrial Control Logic, Appliance Control Boards, Consumer Electronics, Security and Alarm Panels, Automotive Subsystems (Non-Safety), Low-Power Sensor Read-Out.
Industrial Control Logic
The PIC16C62A-10/SO fits industrial control logic because its 3.5 KB OTP EPROM stores deterministic firmware for relay drivers, motor starters, and sensor read-out at 10 MHz. Its 22 I/O pins handle digital inputs from limit switches, encoder feedback, and outputs to SSR/MOSFET drivers without external bus expanders. The wide 2.5-6.0 V supply range tolerates 24 V-derived 5 V rails common in industrial cabinets, while the 15 µA active current and 1 µA sleep current suit always-on equipment. Designers benefit from the PIC16C6x instruction set and Harvard RISC core, which deterministically execute control loops in 200 ns per instruction.
Recommended
Appliance Control Boards
The PIC16C62A-10/SO is well-suited to appliance control boards (washing machines, dishwashers, microwave ovens) where the 8-bit RISC core executes user-interface and motor-control firmware deterministically. The 3.5 KB EPROM stores the full control program, while 128 bytes RAM is sufficient for state-machine variables, timer counters, and key debounce buffers. The 22 I/O pins drive LED indicators, keypads, triac outputs for AC loads, and accept sensor inputs. Its 2.5-6.0 V operation accepts 5 V rails from rectified mains, and the 28-SOIC SMT package suits high-volume automated assembly lines.
Recommended
Consumer Electronics
The PIC16C62A-10/SO serves consumer electronics such as remote controls, toys, audio peripherals, and small home appliances, where its 3.5 KB OTP and 10 MHz RISC core deliver responsive user interaction at low BOM cost. The 1 µA sleep current at 3 V extends battery life in remote controls, while the active 15 µA at 4 MHz keeps continuous-draw applications efficient. The 22 I/O lines accommodate key matrices, IR LEDs, piezo buzzers, and serial peripherals. The 28-SOIC package simplifies global SMT assembly, and the OTP memory deters field firmware tampering in branded consumer products.
Recommended
Security and Alarm Panels
The PIC16C62A-10/SO is appropriate for security alarm panels, keypads, and PIR sensor read-out where its 22 I/O lines interface with reed switches, PIR sensors, sirens, and 4x4 keypads. The 10 MHz clock provides responsive debounce and event logging, and the deterministic RISC core ensures predictable response to alarm events. The 3.5 KB OTP EPROM protects tamper-resistant firmware, while the 128 bytes RAM stores event logs and zone states. The 2.5-6.0 V operation accepts 12 V battery-backed 5 V rails typical of alarm systems.
Recommended
Automotive Subsystems (Non-Safety)
The PIC16C62A-10/SO handles non-safety automotive subsystems such as interior lighting controllers, seat heaters, and accessory drivers, leveraging its 22 I/O pins and wide 2.5-6.0 V supply range that tolerates load-dump transients when paired with proper regulators. The 10 MHz execution handles PWM dimming and switch debounce in real time, while 3.5 KB EPROM stores lookup tables for lighting profiles. The 28-SOIC SMT package is compatible with automotive-grade assembly lines, though this specific variant is commercial temperature; select the -I suffix for industrial-temp designs. For safety-critical paths, migrate to AEC-Q100-qualified PIC16F equivalents.
Recommended
Low-Power Sensor Read-Out
The PIC16C62A-10/SO works in low-power sensor read-out nodes where its 1 µA sleep current at 3 V/32 kHz enables multi-year battery life. The 22 I/O pins connect to analog sensors via external ADCs or comparators, and the 10 MHz active mode processes sensor bursts before returning to sleep. The 128 bytes RAM is adequate for short data buffers and averaging windows, while the 3.5 KB EPROM stores calibration coefficients and IIR filter constants. The 2.5-6.0 V supply range accepts 3.6 V lithium or 3.3 V regulated rails typical of remote sensor nodes.

Design Notes
The PIC16C62A-10/SO uses One-Time-Programmable (OTP) EPROM for program storage. Once programmed, the firmware cannot be altered in-circuit; every firmware revision requires a new part. For iterative development, prototype on a flash-based PIC16F628A-I/SO (same 28-SOIC footprint) and migrate to PIC16C62A-10/SO only when firmware is locked. Estimated: assuming firmware lock at production release, plan for a flash-based pre-production batch to validate the code base.
Decouple VDD/VSS with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin (pin 15) and a bulk 10 µF tantalum or aluminum polymer on the supply rail. Add a 10 kΩ pull-up on MCLR (pin 4) to prevent spurious resets. The PIC16C62A-10/SO has two VDD pins (15 and 28) and two VSS pins (5 and 14); both must be connected for proper operation and to meet the 10 MHz timing margins under load.
Keep the crystal (or external clock) traces between OSC1 (pin 17) and OSC2 (pin 16) short and symmetric, with a ground guard ring around the oscillator components to reduce EMI coupling. The 28-SOIC package has good thermal dissipation for a 10 MHz industrial design, but ensure the PCB copper pour under the device provides at least 1 sq cm of VSS plane for heat spreading. Avoid routing high-speed digital signals adjacent to the oscillator traces.
For ICSP (In-Circuit Serial Programming) during manufacturing test, expose pins RB6 (clock) and RB7 (data) to test pads. The 28-SOIC land pattern is standardized at 1.27 mm pitch; follow IPC-7351 nominal footprints for reliable assembly. If your design uses the PIC16C62A-10/SO alongside an external analog comparator or ADC, keep analog grounds separate and join them at a single point near the PIC's VSS pin to avoid digital switching noise coupling into precision analog readings.
Estimated: at 5 V supply, 10 MHz clock, and 50% I/O toggle load, the PIC16C62A-10/SO dissipates approximately 25 mW internally. Junction-to-ambient thermal resistance (θJA) for the 28-SOIC is approximately 80 °C/W (per Microchip package thermal data, 4-layer JEDEC test board), giving a self-heating temperature rise of 2 °C - well within commercial operating range. No external heatsink is required.
