PIC16C67-04E/PT 概要
A PIC microcontroller (Programmable Interface Controller) is a family of 8-bit, 16-bit, and 32-bit RISC-based microcontrollers originally developed by General Instrument's Microelectronics Division and popularized by Microchip Technology. PIC MCUs occupy the broader taxonomy of microcontrollers (MCU) -> embedded microprocessors -> semiconductors. They integrate a CPU core, program memory (ROM/EPROM/Flash), data memory (RAM), non-volatile EEPROM, timers, capture/compare/PWM peripherals, analog-to-digital converters, and serial communication peripherals (USART, SPI, I²C) on a single chip. The PIC16C family is the mid-range line, sitting between the baseline PIC10/12/16 families and the enhanced PIC17/18 families, and is the family from which the later flash-based PIC16F series evolved.
Key features of the PIC16C67-04E/PT include its 14-bit instruction word architecture, Harvard bus structure, 8-level deep hardware stack, and four interrupt sources. The device supports a wide operating voltage range and offers three timer/counter modules, a Capture/Compare/PWM (CCP) module, a synchronous serial port (SSP) supporting SPI and I²C, a USART for asynchronous serial communication, an 8-bit parallel slave port, and a watchdog timer with its own on-chip RC oscillator for reliable operation.
Typical applications for the PIC16C67-04E/PT include industrial control systems, automotive body electronics, consumer appliance control, sensor signal conditioning front-ends, low-speed data acquisition, and embedded control subsystems requiring up to 33 I/O lines. The wide operating voltage range and external oscillator support make it adaptable to systems with non-standard clock sources, while the 44-pin TQFP package provides a compact footprint for space-constrained designs.
When designing with this device, engineers should note that PIC16C67 is OTP (one-time programmable) and the -04 speed grade limits the oscillator to 4 MHz (vs. the -10 and -20 speed grades available). The 'E' temperature grade designates the extended temperature range (-40°C to +125°C) versus the standard industrial range (-40°C to +85°C of the 'I' suffix).

主な用途
PIC16C67-04E/PT の用途: 6 件s: Industrial Process Control, Automotive Body Electronics, Consumer Appliance Control, Sensor Signal Conditioning, Low-Speed Data Acquisition, Embedded Control Subsystems.
Industrial Process Control
The PIC16C67-04E/PT fits industrial process control applications where deterministic 8-bit control is needed with up to 33 I/O for sensor interfacing and actuator driving. Its 14KB OTP program memory accommodates complex ladder-logic-style state machines, while the USART enables Modbus RTU communication with PLCs and HMIs. The 4 MHz clock provides sufficient bandwidth for PID loop execution at 10 ms control intervals, and the extended -40C to +125C temperature grade handles factory-floor environments. Use the PIC16C67-04E/PT when legacy fieldbus protocols or 5V-only signal chains are required; migrate to PIC16F877A for new designs.
おすすめ
Automotive Body Electronics
The PIC16C67-04E/PT serves automotive body electronics modules such as climate control panels, lighting controllers, and seat adjustment systems. Its 33 I/O lines multiplex well with switch matrices and LED driver arrays, and the CCP module generates PWM for motor speed control and dimming. The extended -40C to +125C temperature grade exceeds automotive under-hood requirements and matches cabin-electronics specs. However, for new automotive designs the AEC-Q100-qualified PIC16F877A-I/PT is preferred over the PIC16C67-04E/PT, which lacks automotive qualification and uses obsolete OTP memory.
おすすめ
Consumer Appliance Control
The PIC16C67-04E/PT is well suited to consumer appliance controllers like washing machines, microwave ovens, and air conditioners where cost-sensitive 8-bit control dominates. Its USART interfaces with inverter boards and sensor modules, while the parallel slave port connects to HMI display controllers. The 14KB OTP holds full appliance state-machine firmware with self-test routines. At 5V operation and 4MHz, power consumption stays under 20 mA active, meeting energy-star standby targets. For modern appliances with touch interfaces, consider the PIC16F877A or PIC18F equivalents.
おすすめ
Sensor Signal Conditioning
The PIC16C67-04E/PT handles sensor signal conditioning front-ends for industrial measurement systems, combining analog comparator inputs with digital I/O for sensor multiplexing. Its 4 MHz clock supports 1 kHz sample rates on multiplexed RTD and thermocouple inputs, and the USART streams processed data to upstream SCADA systems. The 368-byte RAM buffers 16-bit ADC data from external sigma-delta converters like the MCP3551. The wide 2.5V to 6.0V supply range accommodates 3.3V and 5V sensor rails directly, simplifying power tree design in distributed measurement nodes.
おすすめ
Low-Speed Data Acquisition
The PIC16C67-04E/PT forms the core of low-speed multi-channel data acquisition systems where 8-bit resolution and 1 kSPS aggregate throughput are sufficient. Its 33 I/O lines drive analog multiplexer selection logic for up to 32 single-ended input channels, and the SSP module reads external ADC results over SPI at up to 1 MHz clock. The 14KB OTP stores channel calibration coefficients and linearization tables, while the USART streams acquired data to a host PC. The extended temperature grade supports outdoor and industrial cabinet installations without additional thermal management.
おすすめ
Embedded Control Subsystems
The PIC16C67-04E/PT functions as a satellite controller in distributed embedded systems, handling local I/O expansion and serial gateway duties between field devices and a central processor. Its USART bridges RS-232 or RS-485 to a main controller, while the SSP supports SPI peripherals like EEPROM and real-time clocks. With 33 I/O and three timers, it can independently manage local closed-loop control tasks such as motor speed regulation or PWM solenoid driving. The 44-pin TQFP package fits on compact 50 mm x 50 mm satellite PCBs common in modular industrial architectures.

設計ノート
The PIC16C67-04E/PT operates from 2.5V to 6.0V, with 5V being the typical industrial design target. Place a 100 nF decoupling capacitor as close as possible to each VDD pin (pins 11 and 43) and a single 10 uF bulk capacitor at the board's power entry. For battery-backed applications, the brown-out detect circuit triggers a reset when VDD drops below approximately 4V (at 5V nominal), preserving RAM contents. Add a series ferrite bead or 10 ohm resistor on the VDD trace if the supply is shared with inductive loads like relays or motors.
Route the OSC1/OSC2 traces (pins 13 and 14) as short and symmetric as possible, with the crystal or resonator placed within 10 mm of the MCU. Keep these traces away from high-current switching nodes such as relay driver outputs. The MCLR/VPP pin (pin 1) should be pulled up to VDD through a 10 kohm resistor with a 100 nF capacitor to ground for noise immunity; this RC time constant also sets the power-on reset delay. The ICSP pins RB6/PGC (pin 39) and RB7/PGD (pin 40) must be accessible in the final layout for in-circuit programming and debugging.
Do not confuse the PIC16C67 (14KB OTP, 368 RAM) with the PIC16C66 (8KB OTP, 368 RAM) when ordering; the package suffix is identical but the firmware exceeds 8KB on PIC16C66. The '-04' speed grade limits the oscillator to 4 MHz; attempting to drive the device at 20 MHz will result in erratic execution. PIC16C OTP parts cannot be erased or reprogrammed - any code bug requires physical replacement of the IC. For new designs requiring field updates, always choose the flash-based PIC16F877A instead. Watch out for counterfeit PIC16C parts from unauthorized brokers; always verify via Microchip's part marking decoder.
