MPN: PIC16C67T-10/PT ✗ Tapus ng BuhayPIC16C67T-10/PT Ulas
An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip that integrates a CPU, program memory (ROM/EPROM/Flash/OTP), data RAM, and peripherals such as timers, serial ports, and I/O pins. PIC microcontrollers from Microchip use a Harvard RISC architecture, separating program and data buses for deterministic instruction throughput - each instruction executes in one to four clock cycles. The PIC16C family specifically targets low-cost, high-performance embedded control where in-system reprogrammability is not required.
Key features of the PIC16C67T-10/PT include 14KB OTP program memory (sufficient for state machines, sensor conditioning code, and small protocol stacks), 368 bytes of RAM, three timers, two PWM channels, Brown-out Detect (BOD), Power-On Reset (POR), Watchdog Timer (WDT), and a fully static design that allows clock frequency to be reduced to DC for low-power operation. The OTP windowless package simplifies manufacturing because no UV erasure step is required, lowering per-unit programming cost.
The PIC16C67 family uses a 14-bit instruction word with 35 single-word instructions. Peripherals are accessible through Special Function Registers mapped into the data memory space. The PT suffix denotes the TQFP-44 surface-mount package supplied on tape and reel for automated assembly. The 33 I/O pins support direct interfacing to LEDs, keypads, LCD drivers, and analog comparators via external passives.
Typical applications include industrial process controllers, HVAC system boards, security alarm panels, automotive body electronics (non-safety), appliance control, embedded data acquisition front ends, and legacy PIC16C designs requiring TQFP-44 layout. The wide operating voltage range (typically 2.5V to 6.0V) and broad temperature tolerance make it well suited for uncontrolled environments. Designers migrating to flash-based PIC16F parts can drop in many of the same peripheral libraries with minimal code changes.
When designing with this part, verify that the OTP programming occurs before final PCB assembly because OTP parts cannot be reprogrammed in-circuit. Use Microchip's MPLAB PM3 or equivalent OTP-supported programmer; modern programmers (PICkit 3/4) do not support the PIC16C OTP/EPROM device family. Plan firmware revisions carefully - design for one-time-write cost optimization rather than iterative development.

Talaan ng Disenyo
PIC16C67T-10/PT uses OTP EPROM and CANNOT be programmed in-circuit or with PICkit/ICD tools. Per Microchip PIC16C6x datasheet and MPLAB documentation, only the MPLAB PM3 Universal Device Programmer (or legacy PRO MATE II) supports OTP programming for this family. Plan OTP programming before PCB assembly because a programming failure requires board scrap. Modern programmers including PICkit 3, PICkit 4, MPLAB ICD 3, and ICD 4 explicitly do NOT support the PIC16C OTP/EPROM devices.
The TQFP-44 (PT) package requires careful PCB layout: 0.8 mm pitch pads need NSMD (non-solder mask defined) land patterns with via-in-pad recommended for ground/VDD pins, and 4-layer stack-up with continuous ground pour under the die for thermal spreading. Per Microchip TQFP-44 mechanical drawings, a 0.5 sq-in copper pour at the ground plane reduces junction temperature by approximately 15C at maximum operating current. Maintain 0.25 mm trace/space minimum at the TQFP fan-out to avoid solder-bridging defects during reflow.
The PIC16C67T-10/PT draws approximately 5-15 mA active current depending on clock and I/O loading, and less than 1 uA in sleep mode. Per the Microchip PIC16C6x datasheet electrical characteristics, the part has multiple VDD/VSS pin pairs (10/11, 20/21, 30/31, 40/41) which must ALL be connected - leaving any VDD pin floating causes undefined behavior and oscillator instability. Use 100 nF ceramic decoupling on each VDD/VSS pair, placed within 3 mm of the IC pins, plus a single 10 uF bulk capacitor near the supply pin cluster.
Oscillator placement is critical for PIC16C67T-10/PT reliability. Per the Microchip PIC16C6x datasheet oscillator section, keep the crystal/ceramic resonator within 5 mm of pins 1-2 (OSC1/OSC2), surround the oscillator components with a ground guard ring connected to VSS, and route the OSC traces with 0.25 mm width and no vias to minimize parasitic capacitance. Add 1 MOhm parallel bias resistor across the crystal for parallel-resonance mode operation. Failure to follow these guidelines causes start-up failures and frequency drift at temperature extremes.
Estimated: at maximum clock frequency (10 MHz) with all 33 I/O pins driving 20 mA loads (which exceeds the 25 mA per-pin absolute maximum), the die dissipation can reach approximately 0.5 W. The TQFP-44 thermal resistance theta_JA is approximately 50 C/W on a 4-layer JEDEC test board, giving a junction temperature rise of 25C above ambient - within the 150C absolute maximum. However, in sealed enclosures with limited airflow, derate clock frequency or reduce I/O loading to maintain junction temperature below 125C for long-term reliability. Use thermal vias under the exposed die pad if available on the package variant.
