PIC16C67T-04/PT Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces into one package. The PIC16C6x family is classified as a low-power, high-speed CMOS 8-bit RISC MCU family in Microchip's PIC16C mid-range line, itself part of the broader category of microcontrollers, embedded processors, and finally integrated circuits. The 'OTP' program-memory type means the firmware is written once at production and cannot be field-erased, which lowers unit cost in high-volume applications.
Key features include a Harvard RISC architecture with 35 single-cycle instructions, 14-bit wide instruction word, 8-bit data path, four 8-bit timer/counters, two capture/compare/PWM modules, a synchronous serial port (SSP) supporting SPI and I2C, a USART with addressable asynchronous mode, 8-channel 8-bit analog-to-digital converter, and a programmable watchdog timer with on-chip RC oscillator for reliable operation.
The PIC16C67T-04/PT is built on Microchip's low-power CMOS EPROM/ROM process, enabling commercial, industrial, and extended temperature grades with brown-out reset and power-on reset options. Compared with flash-based PIC16F parts, the OTP variant targets cost-sensitive high-volume applications where firmware is finalized before assembly.
Typical applications include industrial control systems, automotive body and chassis subsystems, consumer appliances, security and alarm panels, and smart sensor front-ends where deterministic real-time response and small footprint matter. The wide 2.5 V to 6.0 V supply range also supports battery-backed instrumentation.
When designing with the OTP variant, plan firmware carefully because the program memory cannot be reprogrammed in-circuit. Ensure emulator/ICE support (MPLAB ICE2000/ICE4000) is available during prototype development, or migrate to the pin-compatible PIC16F877 flash variant for prototypes.

Aplicações típicas
PIC16C67T-04/PT é adequado para 6 aplicaçãos: Industrial Process Control, Automotive Body Electronics, Consumer Appliance Control, Security and Alarm Panels, Smart Sensor Front-Ends, Battery-Backed Instrumentation.
Industrial Process Control
The PIC16C67T-04/PT is well suited to industrial process control PLCs and sensor hubs where deterministic real-time response is mandatory. Its 8-bit RISC core executes 35 single-cycle instructions at 4 MHz, giving a 1 microsecond instruction cycle that simplifies PID loop timing. The integrated 8-channel 8-bit ADC reads temperature, pressure, and flow sensors directly, while the two CCP modules generate PWM outputs for valve and motor control.
Recomendado
Automotive Body Electronics
The PIC16C67T-04/PT powers body and chassis modules such as central locking, window lift, mirror control, and HVAC blend actuators. The 33 digital I/O pins drive relays, half-bridges, and LED indicators without external expanders, and the USART interfaces with body control LIN/CAN transceivers. For under-hood applications use the industrial -40C to +85C grade variant. The OTP memory locks firmware at production for security.
Recomendado
Consumer Appliance Control
White goods such as washing machines, dishwashers, and microwave ovens adopt the PIC16C67T-04/PT for its low cost and deterministic control. The integrated 14 KB OTP memory holds the user interface, motor sequencing, and safety logic, while the 368-byte RAM supports real-time state machines. The wide 2.5 V to 6.0 V supply directly accepts rectified 5 V rails without additional regulation, simplifying BOM.
Recomendado
Security and Alarm Panels
Alarm control panels use the PIC16C67T-04/PT to monitor multiple zones, drive piezo sirens, and manage keypad/LED user interfaces. The 33 I/O lines easily handle 16-zone loops, status LEDs, and a 4x4 keypad matrix without external logic. The programmable watchdog timer with on-chip RC oscillator resets the MCU on firmware lockup, critical for unattended security installations. OTP memory prevents firmware tampering.
Recomendado
Smart Sensor Front-Ends
Distributed smart sensor nodes use the PIC16C67T-04/PT as a low-cost analog front-end that digitizes sensors and communicates via SPI or I2C to a host controller. The 8-channel 8-bit ADC samples thermocouples, photodiodes, or load cells, while the MSSP peripheral streams results over a 400 kHz I2C bus. With a 4 MHz clock and CMOS design, the part draws only a few milliamps, suitable for loop-powered 4-20 mA instruments.
Recomendado
Battery-Backed Instrumentation
Portable test instruments and data loggers benefit from the PIC16C67T-04/PT's wide 2.5 V to 6.0 V supply range and fully static CMOS design. Brown-out reset cleanly shuts down on battery sag, protecting 368-byte RAM contents. The 4 MHz clock draws only a few milliamps, while sleep mode drops consumption to microamp levels. OTP memory secures calibration constants and prevents firmware reverse engineering.

Notas de projeto
The PIC16C67T-04/PT uses One-Time Programmable EPROM which cannot be erased or reprogrammed. Validate firmware on a flash-based PIC16F877-04/PT prototype first, then commit the final image to OTP for production. Estimated: each blank OTP unit costs ~USD 5.72 at 1k quantity, so rework is expensive. Always generate CRC checksums on the programmed image and read-back-verify before sealing the device.
Power the PIC16C67T-04/PT from a low-dropout regulator such as the MCP1700 to keep VDD clean within 2.5 V to 6.0 V. Decouple VDD with 100 nF X7R ceramic placed within 5 mm of the VDD pins (11 and 32), plus a bulk 10 uF tantalum. The MCLR/VPP pin requires a 10 kohm pull-up to VDD and a 100 nF decoupling capacitor for reliable brown-out reset operation.
Route the 4 MHz crystal traces between OSC1 (pin 13) and OSC2 (pin 14) symmetrically, with a ground guard ring, to suppress radiated EMI. Place the crystal within 10 mm of the MCU. Keep the MCLR trace short and isolated from high-current switching nodes. The 44-TQFP package has a thermal pad-less bottom; copper pour under the package improves heat dissipation but is not strictly required at 4 MHz speeds.
