PIC16C67T-10/L Обзор
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and peripheral set on one silicon die. Within the system taxonomy, the PIC16C67 sits below 16-bit and 32-bit MCUs but above simple 8-bit controllers in raw throughput. The PIC16C series uses a RISC-style 35-instruction set, where most instructions execute in a single 200 ns cycle at 20 MHz clock input, making code density high and developer ramp-up shallow. The OTP sub-family allows one-time-only programming - cheaper than flash, suitable for mature production where firmware revisions are unnecessary.
Key features of the PIC16C67T-10/L include integrated communication peripherals (I2C, SPI, and UART/USART), on-chip Brown-out Detect/Reset, Power-On Reset (POR), Pulse Width Modulation (PWM), and a Watchdog Timer (WDT). The 33 I/O ports support direct interfacing with sensors, displays, and actuator drivers, reducing external component count. The 10 MHz clock input rating at 4.5 V–5.5 V (vs. the 20 MHz -10 part) maps directly to applications where EMI-sensitive or lower-power operation is acceptable in exchange for a wider timing margin.
Architecturally, the device uses Harvard-bus design with separate program and data paths, allowing instruction fetch and operand access to occur in the same instruction cycle. The 14-bit-wide instruction word (compared to 12-bit for the baseline PIC) yields more efficient encoding of immediate values and jump targets. This generation predates PIC18 and PIC24/dsPIC; code compatibility stops at PIC16F/PIC16C with the same 14-bit core.
Typical applications include industrial control logic nodes, appliance control boards, automotive body-electronics modules (subject to AEC-Q100 evaluation), and embedded instrumentation. The PLCC-44 socketed form factor suits legacy designs and easy field replacement. When designing with this part, note that OTP memory cannot be erased; engineering samples must be windowed CERDIP variants (PIC16C67-10/L not -JW), and production programming must use a gang programmer such as MPLAB PM3.

Типичное применение
PIC16C67T-10/L подходит для 6 применениеs: Industrial Control Logic Nodes, Appliance Control Boards, Automotive Body Electronics Modules, Embedded Instrumentation and Data Loggers, Legacy Replacement and Field Service, Educational and Development Platforms.
Industrial Control Logic Nodes
The PIC16C67T-10/L fits industrial control logic nodes because its 33 I/O pins, 14 KB OTP program memory, and integrated peripherals (PWM, WDT, Brown-out Reset) cover most discrete control tasks in one chip. With 10 MHz core speed and 400 ns instruction cycles, it executes ladder-logic-equivalent state machines with ample timing margin at industrial 5 V rails. The OTP memory enforces production firmware stability - critical for safety-of-function nodes where field reprogramming is undesirable.
Рекомендуется
Appliance Control Boards
The PIC16C67T-10/L is a strong fit for appliance control boards (washers, dryers, dishwashers) where its 5 V operating range, 33 I/O lines, and PWM output directly drive relays, triacs, valve solenoids, and LED/LCD displays. The 14 KB OTP holds complex user-interface state machines, while the on-chip WDT and Brown-out Detect protect against motor-induced supply dips. The PLCC-44 socketed package simplifies service and field replacement in long-life appliances.
Рекомендуется
Automotive Body Electronics Modules
The PIC16C67T-10/L is used in non-safety automotive body-electronics modules (interior lighting, seat controllers, mirror adjusters) where its 4.5 V to 5.5 V supply tolerates 12 V battery transients after regulation. The integrated UART/USART and SPI connect to body-network gateways. For under-hood or AEC-Q100 required applications, the commercial 0 C to 70 C temperature grade is insufficient - select PIC16C67T-10I/L (industrial) or migrate to a PIC18/dsPIC AEC-Q100 part.
Рекомендуется
Embedded Instrumentation and Data Loggers
The PIC16C67T-10/L supports embedded instrumentation and slow-speed data loggers because its 14 KB OTP, 368-byte RAM, UART/USART, and I2C peripheral set connect directly to sensors and EEPROM/FRAM storage. The 10 MHz clock and single-cycle 35-instruction RISC core efficiently runs acquisition loops at sub-kHz rates. OTP enforces that the calibration coefficients burned at production are never overwritten in the field.
Рекомендуется
Legacy Replacement and Field Service
The PIC16C67T-10/L serves legacy replacement and field-service roles where 44-pin PLCC sockets are already installed in long-lifecycle equipment. Its drop-in compatibility with PIC16C67-10/L, PIC16C67-20/L, and PIC16C67T-20/L allows service technicians to substitute with speed-grade or carrier variants without PCB rework. The OTP memory also makes it attractive as a counterfeit-resistant alternative to flash parts - genuine PIC16C67 cannot be reprogrammed with malicious code.
Рекомендуется
Educational and Development Platforms
The PIC16C67T-10/L is a useful educational platform for embedded-systems curricula that teach 8-bit MCU fundamentals, OTP programming economics, and legacy PLCC soldering techniques. The 35-instruction RISC architecture is small enough for full mastery in one semester, while the 33 I/O pins and PWM/ADC/WDT peripheral set provide enough complexity for non-trivial labs. Microchip MPLAB PM3 and PICSTART Plus programmers natively support this device for classroom lab use.

Заметки по проектированию
The PIC16C67T-10/L operates from 4.5 V to 5.5 V nominal with a broader 4 V to 6 V tolerance window. Place a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 37 and 38) and a single 10 uF bulk capacitor near the package. The PIC16C67 has two VDD and two VSS pins - both must be connected for proper POR operation. Use a watchdog timer (WDT) enabled in software to recover from supply-brownout conditions in industrial environments.
OTP program memory cannot be electrically erased - once programmed, the PIC16C67T-10/L is committed permanently. For development and debugging, use a windowed CERDIP PIC16C67-10/JW sample that allows UV erasure, then burn production firmware into the PLCC OTP parts only after code is finalized. If you accidentally program incorrect firmware into an OTP unit, the part is scrap - this is the key trade-off versus flash-based PIC16F equivalents.
The 44-pin PLCC (J-lead) package is socketed and field-replaceable. Use a quality PLCC-44 surface-mount socket (e.g., 3M 8444-21B1-RK or equivalent) when designing service-friendly boards. Reserve a clear keep-out area around the package for socket insertion/extraction tools. The PLCC outline is significantly larger than the equivalent TQFP-44 footprint - if board area is critical, consider migrating to PIC16F887-I/PT in TQFP-44.
