PIC16C62B-04I/SS - 4MHz 8-Bit OTP MCU, 3.5KB | Microchip
MPN: PIC16C62B-04I/SS ✗ Cuối đờiPIC16C62B-04I/SS Tóm tắt
A PIC microcontroller (Programmable Interrupt Controller, though in Microchip's usage it stands for Peripheral Interface Controller) is a compact, single-chip computer integrating a CPU core, non-volatile program memory, volatile RAM, and configurable peripherals such as timers, comparators, capture/compare/PWM modules, and serial I/O. Within the broader taxonomy, the PIC16C62B sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit RISC MCU -> mid-range PIC16 family -> CMOS OTP variant. The 16C-series OTP parts are one-time-programmable, distinct from the flash-based 16F-series that dominate new designs, making the 16C62B useful for legacy industrial systems, secure applications where firmware must not be field-updateable, and cost-optimised production runs.
Key features include two 8-bit timers (Timer0, Timer2) plus one 16-bit Timer1, a 5-channel 8-bit A/D converter (PIC16C62B variant specific), a USART/SCI module for asynchronous and synchronous serial, an SSP module for SPI/I2C, a watchdog timer with on-chip RC oscillator, brown-out reset, and power-on reset. The device operates across 2.5V to 6.0V (typical 5V) with low-power sleep current. Three I/O ports (PORTA 6 pins, PORTB 8 pins, PORTC 8 pins) provide flexible digital interfacing.
Architecturally, the PIC16C62B uses a Harvard RISC core with separate program and data buses, a 14-bit-wide instruction path, and a hardware stack eight levels deep. The OTP EPROM cell is windowless on plastic SSOP, ensuring firmware cannot be read back optically, a security feature for legacy industrial controls. The CMOS process yields low quiescent current, with sleep currents below 1 microB typical.
Typical applications include industrial motor control (small DC and stepper drives), appliance controllers (washing machines, microwave ovens), security and access control panels, smart sensor signal conditioning with on-chip ADC, automotive body electronics (pre-CAN legacy modules), and instrumentation front-ends where deterministic timing matters. Designers also deploy the PIC16C62B in safety-critical legacy systems because OTP firmware is immune to bit-flip induced corruption.
When designing with the PIC16C62B-04I/SS, ensure the programming firmware is fully validated before mask/OTP commit because OTP parts cannot be re-programmed. Use MPLAB development environment with ICD or PM3 programmer. For new designs consider flash-based PIC16F628 or PIC16F88 equivalents, but for legacy system replacement the C62B remains a drop-in solution.

Ứng dụng tiêu biểu
PIC16C62B-04I/SS phù hợp cho 6 Áp dụngs: Industrial Motor and Solenoid Control, Home Appliance Control Boards, Security and Access Control Panels, Smart Sensor Signal Conditioning, Automotive Body Electronics (Legacy Modules), Instrumentation and Test Equipment Front-Ends.
Industrial Motor and Solenoid Control
The PIC16C62B-04I/SS's 4 MHz deterministic 8-bit RISC core, 22 I/O lines, and 5-channel 8-bit ADC are ideal for small DC and stepper motor controllers in industrial machinery. Its OTP EPROM firmware prevents accidental field reprogramming that could cause unsafe operation, while the Timer0/Timer1/Timer2 trio enables precise PWM generation for servo-loop control. Industrial -40 C to +85 C qualification supports factory-floor deployments without additional thermal hardening.

Home Appliance Control Boards
Washing machines, microwave ovens, dishwashers, and refrigerator controllers benefit from the PIC16C62B-04I/SS's compact 28-pin SSOP footprint, low cost, and OTP firmware that locks control algorithms against reverse engineering. The integrated brown-out reset, watchdog timer, and power-on reset improve appliance reliability against mains brown-outs, while the 5-channel ADC digitises temperature and humidity sensor inputs for thermostatic regulation.
Được đề xuất
Security and Access Control Panels
The PIC16C62B-04I/SS is widely deployed in legacy alarm panels, access controllers, and intrusion-detection systems because OTP EPROM prevents firmware tampering - an attacker cannot re-flash the controller with malicious code via debug interfaces. The PIC16C6xx USART enables keypad-to-host communication, while PORTB interrupts handle PIR motion and door-magnetic sensors. Existing field deployments worldwide remain operational and require ongoing replacement stock.

Smart Sensor Signal Conditioning
Front-end signal conditioning for strain-gauge bridges, thermocouples, and thermistor arrays leverages the PIC16C62B-04I/SS's 5-channel 8-bit ADC and Timer1 capture input for frequency-output sensors. With 3.5 KB OTP firmware, calibration coefficients and linearisation tables are locked at production, preventing field tampering with measurement accuracy. The 5 V operating range matches industrial transducer supplies and simplifies 4-20 mA loop interfaces.

Automotive Body Electronics (Legacy Modules)
Pre-CAN-era automotive body controllers, lighting modules, and seat-position memory systems relied on the PIC16C62B-04I/SS for its industrial -40 C to +85 C temperature range, OTP firmware security, and 22 I/O lines. The PIC16C6xx family is documented in many automotive reference designs from the late 1990s and early 2000s, and the part remains in service for legacy vehicle maintenance and spare-part replacement in commercial fleets.

Instrumentation and Test Equipment Front-Ends
Laboratory bench instruments, multimeters, and oscilloscope front-ends use the PIC16C62B-04I/SS for deterministic control of relay multiplexers, display drivers, and rotary encoder inputs. The PICmicro Mid-Range Reference Manual (DS33023) documents the deterministic 4-cycle instruction timing, allowing accurate time-base generation for measurement instrumentation. The 28-pin SSOP footprint fits dense multi-channel boards.

Ghi chú thiết kế
The PIC16C62B-04I/SS operates from 2.5 V to 6.0 V (typical 5 V) with separate analog and digital supplies on the SSOP package. Place a 100 nF ceramic decoupling capacitor adjacent to each VDD pin (pins 19 and 28) with a 10 microF bulk tantalum or aluminium-polymer capacitor near the regulator output. For ADC accuracy, route AVdd/AVss on the same die through pin 19/18 respectively, and avoid high-current digital traces under the analog references to minimise switching noise coupling into the 5-channel ADC.
OTP EPROM programming requires 13 V on MCLR/VPP with specific timing per the PIC16C6xx datasheet programming specification; the SSOP package is plastic and lacks a UV-erase window, so firmware MUST be fully verified before device commit. Use MPLAB X IDE with PM3 or ICD-compatible programmer. Brown-out reset must be configured (BOREN bit) for industrial deployments; without BOR, slow-rising supplies can latch the MCU in indeterminate states. Watchdog timer postscaler must be cleared in long-running loops to prevent unintended reset.
Place a 4 MHz or resonator crystal within 5 mm of OSC1 (pin 8) and OSC2 (pin 9) with short, symmetric traces to ground. For high-noise environments, add a 1 microF capacitor on MCLR/VPP (pin 1) to ground to prevent spurious resets. The SSOP 5.30 mm body width requires careful solder paste stencil design - use 0.15 mm aperture thickness with 1:1 pad-to-stencil ratio for reliable production assembly per IPC-7525 guidelines.
