PIC16LC65AT-04I/PT - 8-bit MCU, 7KB OTP, 4MHz, 44-TQFP | Microchip
MPN: PIC16LC65AT-04I/PT ✗ اختتامِ زندگیPIC16LC65AT-04I/PT جائزہ
An OTP-based PIC16 microcontroller is a member of the 8-bit microcontroller family (PIC16 -> mid-range 8-bit MCU -> microcontroller -> embedded processor -> semiconductor). The "LC" prefix denotes the low-voltage CMOS variant, allowing operation across 2.5 V to 6.0 V system rails and suiting battery-backed instrumentation. The OTP program memory provides one-time programmable storage - ideal for mature, stable firmware in production where re-programmability is not required.
Key features include a Harvard RISC architecture with 35 single-word instructions, an 8-level deep hardware stack, an integrated Power-on Reset and Brown-out Reset, a Watchdog Timer with its own on-chip RC oscillator, and three I/O ports (PORTA/PORTB/PORTC). The PIC16CXX core delivers deterministic 4 MHz instruction throughput suitable for real-time control loops.
The part's 44-pin TQFP (PT) package exposes 33 digital I/O lines, three timer/counter modules, a synchronous/asynchronous USART, and a 5-channel 8-bit ADC. This peripheral combination supports moderate-complexity embedded designs such as motor control loops, sensor front-ends, and human-machine interfaces.
Typical applications include industrial process controllers, sensor signal conditioning front-ends, low-power instrumentation, motor control PWM drivers, and white-goods control boards. The -04I suffix specifies the 4 MHz speed grade and the industrial -40C to +85C operating temperature range. Designers select this part for mature, low-cost production builds where the OTP cost advantage outweighs the need for in-field re-programmability.

عام استعمالات
PIC16LC65AT-04I/PT کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Process Controllers, Motor Control PWM Drivers, Sensor Signal Conditioning, White Goods Control Boards, Low-Power Instrumentation, Human-Machine Interface (HMI) Controllers.
Industrial Process Controllers
The PIC16LC65AT-04I/PT fits industrial process controllers because its 7 KB OTP program memory, 33 I/O lines, and USART interface deliver enough peripherals to drive sensor front-ends, 4-20 mA loop interfaces, and relay-actuated outputs. The 4 MHz core executes PID control loops at 1 MHz instruction rate with deterministic latency, while the three timer/counter modules support PWM for proportional valve control. The -40C to +85C industrial temperature range and 2.5-6.0 V supply allow deployment on factory floors with 24 V or 5 V system rails. Its low cost supports high-volume production of PLCs, motor starters, and sensor signal conditioners where the OTP cost advantage outweighs the need for in-field re-programmability.

Motor Control PWM Drivers
The PIC16LC65AT-04I/PT fits brushed-DC and stepper motor control because its three timer/counter blocks drive PWMP outputs for PWM generation up to 10 kHz, and the 33 I/O lines handle quadrature encoder feedback, H-bridge control, and current-sense inputs. The 4 MHz core executes the commutation interrupt service routine within 5 microseconds per commutation event, well within the typical 50-microsecond cycle time of motor PWM loops. The 8-bit ADC samples motor current at up to 100 kS/s, while the USART streams telemetry to a host controller. The 2.5-6.0 V supply operates directly from battery or 5 V logic rails, making it ideal for portable and industrial motor drives.

Sensor Signal Conditioning
The PIC16LC65AT-04I/PT fits sensor signal-conditioning front-ends because its 5-channel 8-bit ADC digitizes up to five analog sensors simultaneously at up to 100 kS/s aggregate sample rate. The 7 KB OTP program memory holds calibration coefficients and linearization tables for thermocouples, RTDs, and bridge pressure sensors. The 192-byte RAM buffers 8 samples per ADC channel before triggering a USART transfer, and the 33 I/O lines drive 7-segment displays, button keypads, and indicator LEDs. The 2.5-6.0 V wide supply range allows direct interface to 3.3 V sensors and 5 V actuators on a single PCB, eliminating level-shifters.

White Goods Control Boards
The PIC16LC65AT-04I/PT fits white-goods control boards (washing machines, dishwashers, ovens) because its -40C to +85C industrial temperature range survives appliance thermal stress, and its 33 I/O lines drive buttons, LED indicators, triac-controlled heating elements, and buzzer alarms. The three PWMP channels control motor speed for the drum or pump, while the 8-bit ADC reads thermistor inputs at 100 kS/s. The 7 KB OTP program holds appliance firmware with calibration data, and the 192-byte RAM supports small state-machine buffer. The 2.5-6.0 V supply runs directly from rectified mains, eliminating extra LDO stages.

Low-Power Instrumentation
The PIC16LC65AT-04I/PT fits battery-powered low-power instrumentation because its PIC16CXX core operates at 1 MHz instruction rate from 2.5-6.0 V, consuming under 2 mA active and 1 microamp in Sleep mode. The 7 KB OTP stores calibration routines and measurement cycles, and the 33 I/O lines drive LCD segments and power-management FETs. The 192-byte RAM holds measurement buffers between Sleep cycles, while the Watchdog Timer and Brown-out Reset provide robust recovery from brown-out events. This part enables battery lifetimes of 5+ years in remote data loggers, handheld instruments, and portable meters.

Human-Machine Interface (HMI) Controllers
The PIC16LC65AT-04I/PT fits HMI controllers because its 33 I/O lines scan up to 4x8 matrix keypads and drive multiplexed 7-segment or 14-segment LED displays. The three timer/counters handle display multiplexing, debounce, and backlight PWMP dimming without CPU intervention, freeing the 4 MHz core for application logic. The USART interface streams HMI events to a host PLC, and the 7 KB OTP holds menu structures, font tables, and communication stacks. The 8-bit ADC reads potentiometer inputs for analog adjustments. The 44-TQFP package mounts on compact HMI PCBs with industry-standard footprint.

ڈیزائن نوٹس
The PIC16LC65AT-04I/PT requires a stable VDD supply between 2.5 V and 6.0 V with at least 100 mV peak-to-peak ripple tolerance. Place a 0.1 microfarad ceramic decoupling capacitor as close as possible to the VDD pin, plus a 10 microfarad electrolytic capacitor on the analog supply (AVDD). Brown-out Reset is internally set; do not disable it as the Watchdog Timer may not recover from a noisy VDD event.
Route the oscillator circuit (crystal plus 22 pF load capacitors) within 5 mm of the OSC1/OSC2 pins. Keep high-current traces (motor drivers, relay coils) at least 5 mm away from the oscillator loop to prevent EMI injection. The 44-TQFP package has a center thermal pad; tie it to VSS for mechanical stability and improved thermal dissipation.
The ICSP pins RB6 (PGC) and RB7 (PGD) double as general-purpose I/O. If they are configured as outputs by firmware, in-circuit programming is impossible. Reserve these pins as inputs, or accept that production programming requires sockets. The MCLR pin must be pulled high via a 10 kohm resistor; do not leave it floating as the device will randomly reset.
