PIC16C65A-10I/L - 8-Bit 10MHz OTP MCU 7KB | Microchip
MPN: PIC16C65A-10I/L ✗ Cuối đờiPIC16C65A-10I/L Tóm tắt
An 8-bit microcontroller (MCU) is a small, self-contained computing system on a single chip that integrates a CPU, program memory (ROM/EPROM/Flash/OTP), working RAM, and programmable I/O peripherals. The PIC16C6X family uses a Harvard RISC architecture with separate program and data buses, only 35 single-word instructions, and all single-cycle instruction execution except program branches (which take two cycles). In the system hierarchy this places PIC16C65A-10I/L at: 8-bit MCU -> RISC microcontroller -> embedded controller -> semiconductor IC.
Key features include 33 I/O lines spread across multiple ports, a peripheral feature set derived from PIC16C66/67 (synchronous/asynchronous serial ports, PWM, capture/compare timers, 8-bit A/D converter channeling), brown-out reset, watchdog timer, and low-power SLEEP/idle modes. The OTP program memory is one-time programmable using programmers such as MPLAB PM3, which is a hard requirement for production designs where firmware is finalized.
Typical applications include industrial control panels, instrumentation, motor control front-ends, sensor interfacing nodes, and legacy embedded systems that require a robust 8-bit core with abundant I/O. Industrial-grade temperature rating (-40C to +85C) and the 44-pin PLCC package make it a strong fit for through-hole-style industrial backplanes and field-replaceable modules.
When designing with this device, ensure that the chosen programmer supports the PIC16C65A OTP window (PM3 recommended) and that the brown-out and watchdog configuration bits match the application's fault-recovery strategy. Note that OTP parts cannot be re-programmed, so firmware validation must be finalized before production programming.

Ứng dụng tiêu biểu
PIC16C65A-10I/L phù hợp cho 6 Áp dụngs: Industrial Control Panels, Instrumentation and Data Acquisition Front-Ends, Sensor Interfacing and HVAC Nodes, Motor Control Front-Ends (Brushed DC / Stepper), Legacy Embedded Systems and Field-Replaceable Modules, User Interface / HMI Keypad and LCD Controllers.
Industrial Control Panels
The PIC16C65A-10I/L fits industrial control panels because of its 33 I/O pins (sufficient for keypad scanning, LED/LCD multiplexing, relay drivers, and discrete sensor inputs) and its industrial-grade -40C to +85C temperature range, which is required for factory-floor enclosures. With 7 KB OTP and 192 bytes RAM, it can run PID algorithms, manage HMI scan loops, and drive 7-segment or character-LCD displays without external glue logic. Its 15 uA typical operating current at 5V/4 MHz is a strong fit for 24V-powered cabinet systems with simple linear regulators. The 44-pin PLCC package also supports socketed field replacement on legacy panels.

Instrumentation and Data Acquisition Front-Ends
In instrumentation front-ends, the PIC16C65A-10I/L provides 33 I/O lines that can directly drive multiplexed analog front-ends, sample-and-hold circuits, and display readouts. The PIC16C6X core integrates timers suitable for capture/compare operations used in frequency and period measurement. Its 7 KB OTP program memory holds calibration tables and linearization routines for sensors. Wide 2.5V-6.0V supply tolerance allows the part to share rails with analog sections powered directly from unregulated supplies. Industrial temperature grade makes it suitable for laboratory and field-portable instruments.

Sensor Interfacing and HVAC Nodes
The PIC16C65A-10I/L suits distributed HVAC and building-automation sensor nodes because it can scan multiple temperature/humidity sensors over its 33 I/O pins while consuming only 1 uA typical at 3V/32 kHz during sleep. The PIC16C6X core's low-power SLEEP mode combined with watchdog-based wake-up enables battery-powered or energy-harvested nodes with years of operating life. Industrial temperature tolerance supports rooftop and plant-floor installations. The 44-pin PLCC package also provides mechanical robustness against vibration in equipment-cabinet mounting.

Motor Control Front-Ends (Brushed DC / Stepper)
For brushed-DC and unipolar stepper motor control front-ends, the PIC16C65A-10I/L delivers PWM outputs through its CCP module and 33 I/O lines for H-bridge enable, direction, and current-sense feedback. The 7 KB OTP is adequate for trapezoidal commutation tables and acceleration ramps. Operating from 5V with 15 uA typical current keeps power dissipation low for densely packed control boards. Industrial temperature grade supports under-hood and outdoor cabinet deployments. The 44-pin PLCC also allows easy socketed replacement during commissioning and field service.

Legacy Embedded Systems and Field-Replaceable Modules
The PIC16C65A-10I/L is a strong fit for maintaining long-lifecycle legacy equipment because the 44-pin PLCC socket allows field replacement without desoldering. With 7 KB OTP and 192 bytes RAM, it can serve as a drop-in controller for legacy industrial protocols and proprietary field buses. Its DC to 20 MHz clock input range (10 MHz speed grade here) provides timing headroom for bit-banged serial interfaces. Industrial temperature rating is required for many factory-floor installations. Because the part is now obsolete, designers often use PIC16C65A-10I/L as a known-good replacement for service stock.

User Interface / HMI Keypad and LCD Controllers
The PIC16C65A-10I/L is well-suited for keypad-and-LCD HMI controllers with 33 I/O pins enabling 4x4 or 5x5 matrix keypads, multiple status LEDs, and character-LCD interfaces (4-bit or 8-bit mode). Its 7 KB OTP program memory holds menu state machines and string tables for character displays, while 192 bytes RAM holds screen buffers and key-debounce state. 10 MHz instruction throughput keeps display refresh rates fast enough to avoid flicker on multiplexed LED arrays. Industrial temperature grade supports outdoor kiosks and machine-front panels in harsh environments.

Ghi chú thiết kế
PIC16C65A-10I/L uses One-Time Programmable (OTP) EPROM - the device can be programmed exactly once and cannot be erased or re-programmed. Always validate firmware on a flash-based PIC16F equivalent or development part before committing to OTP programming in production. A single configuration-bit error at programming time destroys the part. Use the MPLAB PM3 Universal Device Programmer with verified programming scripts.
The PIC16C65A-10I/L operates from 2.5V to 6.0V with 15 uA typical current at 5V/4 MHz and 1 uA typical at 3V/32 kHz. The wide supply range allows direct connection to 5V linear rails but verify decoupling: place a 100 nF ceramic capacitor close to VDD (pin 5 on 44-PLCC) and a bulk capacitor (10 uF or larger) on the supply node. Brown-out reset configuration bits must be set to match the application's minimum operating voltage to avoid spurious resets.
The 44-pin PLCC package is surface-mount J-lead (16.59x16.59 mm body) with package code QCCJ. Use a socket (e.g., 44-PLCC through-hole or SMD socket) for prototype and field-service designs to allow easy replacement - the part is obsolete so serviceability matters. Place decoupling capacitors within 5 mm of each VDD/VSS pair and route MCLR with a short trace and 10 kohm pull-up to VDD for proper reset behavior.
Estimated: at 5V supply, 10 MHz clock, and full I/O loading, the PIC16C65A-10I/L dissipation is below 50 mW (typical 5 mA I-dd + I/O current). Junction temperature rise is minimal even at industrial 85C ambient - thermal management is not a primary concern for this CMOS MCU. Ensure however that I/O sink/source currents stay within the datasheet maximum per-pin (typically 25 mA) and per-port limits to avoid on-die heating.
Thông tin tuân thủ
Compliance status not explicitly stated in the verified web data. PIC16C65A family is industrial-temperature-rated but not AEC-Q100 qualified for automotive. RoHS status unknown - this part predates widespread RoHS transition so may be non-compliant; check with Microchip for the latest compliance documentation.
