PIC16C67-10I/PT - 8-Bit 10MHz 14KB OTP MCU, 44-TQFP | Microchip
MPN: PIC16C67-10I/PT ✗ اختتامِ زندگیPIC16C67-10I/PT جائزہ
An 8-bit microcontroller (MCU) is a small single-chip computer that integrates a CPU, non-volatile program memory, working RAM, peripheral set (timers, USART, ADC, I/O), and an interrupt controller on a single die. PIC microcontrollers sit within the broader category of microcontrollers -> microcontrollers (embedded computing) -> semiconductors. The PIC16C family (PIC mid-range 14-bit instruction set) is engineered for deterministic real-time control with a fully static design, allowing the clock to be stopped without losing internal state.
Key features of the PIC16C67-10I/PT include the 14-bit instruction word (which gives 8K single-word instructions per 14KB array), an integrated 8-bit A/D converter with multiple input channels, two 8-bit timers plus one 16-bit timer/counter, a USART module with synchronous/asynchronous modes, a watchdog timer with on-chip RC oscillator, and a wide 2.5V to 6.0V operating voltage range. The device also supports in-circuit serial programming (ICSP) via the RB6/RB7 pins for OTP reprogramming during prototyping.
Architecture details: the PIC16C67 uses a Harvard architecture with separate program and data buses, allowing instruction fetch and data access in a single cycle. The 14-bit instruction word provides richer opcode encoding than 12-bit PIC cores, enabling larger immediate operands and direct addressing across the full data memory. The fully static design allows low-power operation by halting the clock, while the brown-out reset and power-on reset circuits simplify supply supervision.
Typical applications span industrial control and instrumentation, HVAC actuator and sensor interfaces, motor control front-ends, automotive body and chassis subsystems, white-goods and appliance controllers, and embedded data-acquisition front ends that need parallel I/O and a USART for host communication. The wide temperature range also makes it suitable for outdoor or factory-floor environments.
Design consideration: OTP memory cannot be re-programmed in the field - designs using the PIC16C67-10I/PT must either be masked-ROM programmed in volume (PIC16CR67) or moved to a flash-based equivalent such as the PIC16F877 for field-updatable firmware. Plan programming flow accordingly.

PIC16C67-10I/PT کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Process Control Front End, HVAC Actuator and Damper Controller, Automotive Body and Chassis Subsystems, White-Goods and Appliance Controllers, Embedded Data-Acquisition Front End, Educational and Hobbyist Embedded Platform.
Industrial Process Control Front End
The PIC16C67-10I/PT's 33 digital I/O lines, 8-channel 8-bit ADC and USART make it well-suited to industrial process control front ends that aggregate sensor inputs and forward filtered readings to a host PLC over RS-232/RS-485. Operating from 4.0V to 6.0V at up to 10 MIPS, it samples multiple analog channels, runs deterministic control loops in software and drives actuator outputs through its PWM/CCP and timer peripherals. The -40C to +85C industrial temperature rating permits deployment in factory-floor cabinets and outdoor enclosures. Pin-to-pin compatibility with the flash-based PIC16F877-10I/PT allows easy migration to in-field reprogrammable firmware when product life extends beyond the OTP silicon stock.

HVAC Actuator and Damper Controller
The PIC16C67-10I/PT is a natural fit for HVAC damper and valve actuators that need multiple PWM channels, ADC inputs for temperature/pressure sensors, and a USART for communicating with the building automation bus. Three timers (2x 8-bit, 1x 16-bit) and dual CCP/PWM blocks generate precise servo and proportional-valve drive waveforms; the 8-channel ADC reads thermistor or 0-10V feedback signals. Industrial temperature range and OTP memory reduce the risk of accidental firmware tampering in sealed building-control hardware. Same 44-TQFP footprint simplifies PCB reuse across the PIC16C66, PIC16C67 and PIC16F877 family variants.

Automotive Body and Chassis Subsystems
With 33 I/O and a USART, the PIC16C67-10I/PT is widely used in automotive body controllers for low-speed functions such as seat-position memory, mirror folding, interior lighting dimming and wiper timing. The 14KB program memory accommodates state-machine logic for multiple subsystems without external memory expansion; 8-channel ADC reads battery voltage, switch positions and analog sensors. Designers migrate to PIC16F877A or PIC16F887A for AEC-Q100 qualified automotive programs while keeping the same 44-TQFP footprint. Wide 4.0V to 6.0V supply tolerates crank-droop and load-dump events after external TVS protection.

White-Goods and Appliance Controllers
White-goods and small-appliance control boards rely on the PIC16C67-10I/PT's combination of OTP memory, ample I/O and integrated ADC to keep BOM cost low while supporting wash-cycle timers, motor-direction logic, user-interface key scanning and triac phase-angle control. The 14KB program memory holds full state-machine plus display drivers, and the 33 I/O pins drive LED/LCD indicators, keypad matrix and zero-cross detection. Industrial temperature grade supports unheated appliance enclosures. The flash-based PIC16F877A-I/PT is the recommended long-term replacement for new SKUs that need post-sale firmware updates.

Embedded Data-Acquisition Front End
The PIC16C67-10I/PT serves as a low-cost data-acquisition front end that aggregates analog and digital channels and forwards packets over its USART to a host PC or embedded gateway. Its 8-channel 8-bit ADC samples at up to ~20 kS/s aggregate (per PIC16C6X datasheet) which is adequate for thermocouple-multiplexed, slow-process telemetry. The USART plus external RS-485 transceiver (MAX485) supports multi-drop 4-20 mA replacement networks; OTP memory protects calibration constants from unintended erasure. Engineers designing new DAQ modules should evaluate PIC16F877-10I/PT for the same footprint and the convenience of flash-based field calibration updates.

Educational and Hobbyist Embedded Platform
The PIC16C67-10I/PT and its wider PIC16C6X family are a classic teaching platform for 8-bit embedded programming thanks to their deterministic Harvard architecture, simple MPLAB toolchain and abundant textbook material. The 14KB OTP, 368-byte RAM, three timers and USART cover every common lab exercise from interrupt-driven keypads to UART bridges, while the 44-TQFP (PT) package exposes 33 breadboard-friendly I/O when mounted on a breakout. Modern classroom kits often swap in the flash-based PIC16F877A-I/PT to allow repeated programming, but the original PIC16C67-10I/PT remains useful for understanding EPROM window erase and OTP programming flows.

ڈیزائن نوٹس
OTP EPROM cannot be re-programmed. A single bad firmware build requires scrapping the part. For development, place the PIC16C67-10I/PT in a socketed daughter-card so a fresh unit can be swapped in for each iteration; move to the flash-based PIC16F877-10I/PT once firmware stabilizes. Verify programming voltage timing against the PIC16C6X datasheet programming specification - VPP rise time and MCLR/VPP sequence are common sources of verify errors.
The PIC16C67-10I/PT requires both VDD pins (11 and 32) and both VSS pins (12 and 31) on the 44-TQFP to be connected. Decouple each VDD pin with a 100nF ceramic capacitor placed within 5 mm of the pin to suppress switching noise from the internal state machine. Add a 10uF bulk capacitor near the package. Brown-out reset is configurable via configuration fuses - enable it for industrial supplies prone to sag.
Keep the OSC1/OSC2 traces short and surrounded by ground pour to minimize EMI coupling; for crystal mode (XT) place load capacitors within 3 mm of the oscillator pins. Route the MCLR/VPP line away from high-frequency switching nodes - accidental glitches on MCLR can spuriously reset the part. When using ICSP on a populated board, isolate the ICSP connector's PGD/PGC from any in-circuit load with series resistors to allow in-field programming without disconnecting the target.
Estimated: at 10MHz CPU clock and 33 I/O toggling, simultaneous-switching output (SSO) noise can inject 100-200 mV of ground bounce on a poorly-decoupled board. Source-terminate fast edges (>5 ns) with 33-47 ohm series resistors and keep a solid uninterrupted ground plane under the TQFP land pattern. ADC accuracy is sensitive to digital switching - place analog inputs on PORTA pins and avoid toggling nearby PORTB bits during ADC conversions.
Estimated: at 10MHz and 6V Vcc, the PIC16C67-10I/PT draws roughly 10-15 mA active, dissipating 60-90 mW. The 44-TQFP package has theta_JA around 50-60 C/W on a 4-layer 1-oz PCB, giving a junction rise of 3-5 C above ambient - well within the -40 C to +85 C operating range. For sealed enclosures with no airflow, derate CPU clock to 4 MHz (use PIC16C67-04 grade) if internal ambient exceeds 70 C.
