PIC16C67-10E/PQ - 8-bit OTP MCU, 14KB, 10MHz, 44-MQFP | Microchip
MPN: PIC16C67-10E/PQ ✓ Hoạt độngPIC16C67-10E/PQ Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripheral I/O on one silicon die, intended for embedded control applications. PIC16C-series parts sit within the broader taxonomy: 8-bit microcontroller -> CMOS microcontroller -> RISC microcontroller -> microcontroller -> embedded processor -> semiconductor. The PIC16C6x family specifically delivers low-cost OTP/UV-erasable EPROM program memory with a small instruction set (35 instructions) optimized for compact code density and deterministic interrupt latency.
Key features include a wide 2.5V to 6.0V supply range, ultra-low power consumption of 15 µA typical at 5V/4 MHz and 1 µA typical at 3V/32 kHz, fully static design supporting operation down to DC clock, and three timer/counter modules, a USART, and a parallel slave port as standard PIC16C6x peripherals. Industrial and Extended temperature grades are supported per the "-E" (Extended) suffix.
The device uses an EPROM-based Harvard architecture with a 14-bit program word and 8-bit data path, allowing a single 8-bit ALU to fetch and execute from a 14-bit-wide instruction memory in a single cycle. This dual-bus arrangement eliminates the Von Neumann fetch/decode bottleneck and yields deterministic instruction timing critical for real-time control loops.
Typical applications include industrial process controllers, motor and stepper control, automotive body electronics (premium-tier nodes), appliance controls, sensor signal conditioning front-ends, and embedded serial-communication bridges. The 33 I/O and USART simplify keypad/LCD and RS-232 interface designs.
Designers should note that the "-E" suffix denotes the Extended temperature range (-40C to +125C), the "-10" suffix denotes 10 MHz maximum clock, and the "/PQ" suffix denotes the 44-pin Metric QFP (MQFP) package. Because the program memory is OTP (one-time programmable), in-circuit firmware upgrades are not possible; provision a windowed or flash-based sibling such as PIC16F877 for development and field-revision work.

Ứng dụng tiêu biểu
PIC16C67-10E/PQ phù hợp cho 6 Áp dụngs: Industrial Process Controller, Appliance Control Board, Automotive Body Electronics, Sensor Signal Conditioning Front-End, RS-232/RS-485 Serial Bridge, Stepper / DC Motor Controller.
Industrial Process Controller
The PIC16C67-10E/PQ suits industrial process controllers because its 33 programmable I/O, USART, and three timer/counters provide the deterministic timing needed for PID loops and sensor multiplexing at 10 MHz / 200 ns cycle. The 14 KB OTP program space holds a complete Modbus RTU slave plus proportional/integral/derivative calculation tables. Extended -40C to +125C temperature operation permits placement inside unventilated control cabinets. The 368-byte RAM accommodates 30+ process variables and stack depth, while the wide 2.5V-6.0V supply tolerates 24V-bus-derived rails after regulation.

Appliance Control Board
Consumer and white-goods control boards benefit from the PIC16C67-10E/PQ's 8K x 14 OTP program memory for washing-machine, dishwasher, and HVAC sequence logic, plus 33 I/O for keypad scanning, seven-segment LED multiplexing, and triac-fired load control. Ultra-low 15 µA active current at 5V/4 MHz extends standby time in battery-buffered appliances, while 1 µA sleep current at 3V/32 kHz is ideal for power-button wake circuits. The 200 ns cycle supports real-time current zero-crossing detection for phase-angle dimming, and the 44-MQFP package fits standard 50 mm x 50 mm control board outlines.

Automotive Body Electronics
The Extended temperature grade (-40C to +125C) of the PIC16C67-10E/PQ enables body-electronics modules such as seat controllers, mirror adjusters, and lighting multiplex nodes where the operating environment exceeds commercial temperature ranges. The 33 I/O handle multiple LIN sub-nodes and PWM-driven motor bridges; the 14-bit instruction word simplifies encoding multi-channel state machines. Note that the PIC16C67 is not AEC-Q100 qualified; for AEC-Q100 critical safety nodes, migrate to PIC16F1939 or dsPIC33 variants. The wide supply range (2.5V to 6.0V) absorbs automotive crank/battery transients to within part specifications.

Sensor Signal Conditioning Front-End
The PIC16C67-10E/PQ integrates sensor signal conditioning tasks for strain-gauge bridges, thermocouples, and RTD arrays by combining its 33 I/O with the on-chip 8-bit ADC channel routing. The 10 MHz core provides 200 ns deterministic ADC-trigger timing, and the 368-byte RAM buffers oversampled averages before UART forwarding to a host. The fully static CMOS design permits low-clock 32 kHz operation during sleep windows between conversions, drawing just 1 µA, making this MCU suitable for solar/battery-powered field sensors. Its OTP program memory locks the calibration coefficients at production time.

RS-232/RS-485 Serial Bridge
With a hardware USART plus PSP port, the PIC16C67-10E/PQ functions as a protocol-translation bridge between RS-232 sensors and RS-485 multi-drop backbones. The 14 KB OTP holds full Modbus master and slave stacks plus command queues, while the 33 I/O provide status LEDs and dip-switch configuration. The 200 ns cycle handles 115200 baud without missing bits, and the wide 2.5V-6.0V supply tolerates field-installed 24V industrial rails. Surface-mount MQFP packaging suits compact DIN-rail module enclosures.
Được đề xuất
Stepper / DC Motor Controller
The PIC16C67-10E/PQ drives 4-phase stepper motors or dual H-bridge DC motors via its three timer/counters generating PWM and pulse-trains, while the 33 I/O handle end-stop switches, encoder inputs, and LED status. The 10 MHz instruction cycle produces microstepping waveforms up to 20 kHz step rates with 50 µs timer-tick granularity. Extended temperature range supports enclosed cabinet installations. The 14 KB OTP program memory stores acceleration/deceleration profile tables, and the USART interfaces with an HMI panel or PLC host.

Ghi chú thiết kế
Decouple VDD/VSS pairs (pins 10/11 and 27/26) with 100 nF ceramic + 10 µF bulk capacitors placed within 5 mm of the package. The PIC16C67-10E/PQ transitions rapidly between active and sleep modes; insufficient decoupling causes VDD droop that may trigger spurious brown-out resets or instruction corruption. For EMI-sensitive environments add a ferrite bead in series with the supply rail.
Route the OSC1/OSC2 traces as a short, symmetric pair with a grounded guard trace. For a 10 MHz crystal, keep trace length below 10 mm to minimize parasitic capacitance and stray EMI pickup. Place C1/C2 load capacitors as close to the crystal pins as possible; values depend on crystal specification, but 22 pF is a typical starting point for fundamental-mode AT-cut crystals.
PIC16C67-10E/PQ is OTP - the program memory cannot be erased or rewritten once programmed. Verify firmware with a windowed CERDIP PIC16C67-10E/L sample during development before committing to MQFP OTP for production. Migration to flash-based PIC16F877 requires code changes for the F877-specific configuration bits and may need register-init differences for the 10-bit vs 8-bit ADC.
Estimated: the 44-pin MQFP package has a typical theta_JA around 50 C/W in still air. At full 10 MHz active mode drawing 15 mA and full I/O load, internal dissipation is below 100 mW, well within thermal limits. However, in sealed enclosures above 70C ambient, derate clock frequency or reduce I/O drive duty cycle to keep junction temperature below 125C.
Thông tin tuân thủ
RoHS and lead-free status not stated in retrieved distributor listings; verify with Microchip environmental compliance documentation. The PIC16C6x family predates widespread AEC-Q100 qualification programs; use PIC16F1939 or dsPIC33 for AEC-Q100 designs.
