PIC16C67T-10I/PQ Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and peripheral I/O on one die. The PIC16C67 belongs to Microchip's mid-range PIC® family, a register-rich RISC architecture optimized for deterministic interrupt response and very low static power consumption. PIC MCUs sit within the broader category of microcontrollers -> embedded processors -> integrated circuits. This device family pioneered Harvard memory architecture, OTP program memory, and instruction-pipelined execution - foundations that drove the widespread adoption of 8-bit MCUs in industrial control, automotive body electronics, and hobbyist embedded designs through the late 1990s and 2000s.
The PIC16C67 integrates a 10-bit, 8-channel Analog-to-Digital Converter (ADC), a Universal Synchronous/Asynchronous Receiver-Transmitter (USART), a Synchronous Serial Port (SSP) for SPI and I²C, three 16-bit timer/counters, a Capture/Compare/PWM (CCP) module, and a parallel Slave Port. The wide digital I/O count (33 pins) plus analog and serial peripherals make it suitable for mixed-signal embedded nodes. The 14KB OTP memory holds the application firmware and is one-time programmable, which limits the part to production-grade designs where code is finalized.
The mid-range PIC core executes most instructions in a single 200 ns cycle at 10 MHz and supports 35 instructions, 8 hardware stacks, and 8 levels of hardware interrupt priority. The 14-bit instruction word keeps code density high compared with 8-bit CISC MCUs of the same era. Power consumption is typically under 15 mA active at 5V/10 MHz, with brown-out reset, watchdog timer, and power-on reset built in.
Typical applications include industrial control panels, motor control front-ends, instrumentation data acquisition, automotive body controllers, security systems, and embedded sensor hubs. Its 33 I/O pins comfortably drive segmented displays, keypads, and LED indicators alongside analog sensor inputs. In production white-label appliances, the OTP memory prevents code extraction, supporting IP protection.
When designing with the PIC16C67, ensure programming socket compatibility if you plan to migrate to PIC16F flash variants. Brown-out reset and watchdog timer should be enabled in firmware for reliable industrial deployments.

Aplicaciones típicas
PIC16C67T-10I/PQ es adecuado para 6 aplicacións: Industrial Control Panels, Automotive Body Controllers, Instrumentation Data Acquisition, Security and Access Control, White Goods and Appliance Controllers, Embedded Sensor Hubs.
Industrial Control Panels
The PIC16C67T-10I/PQ suits industrial control panels where its 33 digital I/O directly drive relays, solenoids, and segmented LED displays without buffering, while the 10-bit ADC reads 4-20 mA sensor signals through current-sense resistors. Its 14KB OTP memory holds ladder-logic replacement firmware, and the industrial -40 to +85 °C temperature grade tolerates cabinet environments. Compared with newer PIC18F parts, the OTP memory prevents field tampering with production firmware, supporting IP protection for OEM equipment. The 10 MHz core executes PID loops within 200 ns cycle times, sufficient for multi-axis motion control at moderate bandwidths.
Recomendado
Automotive Body Controllers
The PIC16C67T-10I/PQ is well-suited to non-safety automotive body electronics such as window lifters, mirror adjusters, and lighting controllers where its 33 I/O pins drive H-bridges and MOSFET drivers directly. The 10 MHz core handles LIN-style protocol stacks and PWM lighting dimming via the CCP module, while the 10-bit ADC reads battery voltage and current sensors. Compared with newer automotive-grade MCUs, the OTP memory prevents end-user code extraction, which is helpful for OEM proprietary algorithms. The 5V supply is compatible with conventional 12V battery systems after regulation. Industrial temperature grade covers most cabin environments.
Recomendado
Instrumentation Data Acquisition
The PIC16C67T-10I/PQ fits instrumentation data acquisition front-ends where its 10-bit ADC and USART channel digitized sensor data to a host PC. The 14KB OTP memory holds calibration tables and signal-processing routines for thermocouples, strain gauges, or load cells, while the 368-byte RAM is sufficient for moving-window averaging. The 33 I/O expand easily to multiplexed displays, keypads, and status LEDs. Compared with newer PIC18F or dsPIC33 parts, the PIC16C67 trades flash reprogrammability for lower cost and IP security through OTP memory - beneficial for sealed industrial instruments. Industrial temperature grade supports factory-floor deployment.
Recomendado
Security and Access Control
The PIC16C67T-10I/PQ is widely used in security panels and access controllers where its OTP memory holds proprietary encryption keys and access codes without the possibility of in-the-field extraction. The 33 I/O drives keypads, card readers, door strikes, and sirens, while the 10-bit ADC reads analog sensors. The 10 MHz core handles 26-bit Wiegand reader protocols and 4-bit keypad scanning simultaneously. Compared with flash MCUs, OTP prevents firmware copying, supporting IP protection for security OEMs. The industrial temperature grade supports outdoor enclosures.
Recomendado
White Goods and Appliance Controllers
The PIC16C67T-10I/PQ powers washing machines, dishwashers, and microwave oven controllers where its OTP memory holds proprietary cycle algorithms, motor timing tables, and user interface state machines. The 33 I/O directly drives triac interfaces for AC loads, LED displays, and rotary encoder inputs. The 10-bit ADC monitors motor current and temperature sensors for safety interlocks. Compared with newer PIC18F parts, the OTP memory prevents end-user firmware tampering, a regulatory concern for some appliance safety standards. Industrial temperature grade handles appliance environments near heating elements.
Recomendado
Embedded Sensor Hubs
The PIC16C67T-10I/PQ serves as a low-cost sensor hub aggregating data from SPI/I²C sensors and forwarding over USART to a host processor. Its 33 I/O provide ample headroom for sensor selection lines and status LEDs, while the 10-bit ADC handles additional analog sensors. The 14KB OTP memory holds sensor calibration constants and protocol handlers for SPI, I²C, and UART interfaces. Compared with newer Cortex-M0 parts, the PIC16C67 offers deterministic interrupt response critical for time-sensitive sensor sampling, an advantage in industrial sensor hubs.

Notas de diseño
Estimated: The PIC16C67T-10I/PQ typical active current is approximately 13-16 mA at 5V/10 MHz, plus I/O current. With all 33 I/O sourcing 10 mA each, total supply current can reach 350 mA. Ensure the 5V regulator can supply at least 400 mA and use a 100 nF decoupling capacitor within 25 mm of each VDD pin (pins 11 and 32). For battery-powered designs, enable sleep mode and use the watchdog timer for periodic wake-up.
The 44-MQFP package has 0.8 mm pitch gull-wing leads. Solder pad length should be 2.0 mm with a stencil aperture of 0.3 mm × 1.5 mm for reliable paste deposition. Place a 4-layer PCB with continuous ground plane beneath the device to reduce EMI from the internal oscillator. The MCLR pin (pin 1) requires a 10 kΩ pull-up to VDD; if not used, leave it connected to VDD through the resistor.
OTP memory cannot be erased, so plan firmware carefully before programming. Verify the configuration bits (oscillator type, watchdog enable, brown-out voltage, code protection) BEFORE burning the part. For prototype development, use the PIC16F877A which is flash-based and ICSP-programmable. The 14-bit configuration word (地址 2007h) controls oscillator, WDT, BOD, and code protection - a misconfigured word can render the device unusable if code protection is locked without verification.
Estimated: The 44-MQFP package has θJA of approximately 50 °C/W. At 10 mA per I/O × 33 outputs × 0.4 V VOH drop = 132 mW total internal dissipation plus 80 mW core, total ~210 mW yields junction rise of 10 °C above ambient. Industrial temperature grade permits operation up to 85 °C ambient with conservative 35 °C junction rise margin. Adequate for sealed industrial enclosures; for >50 °C ambient, derate I/O drive strength in firmware.
