PIC16C62A-10I/SS 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, RAM, peripherals, and I/O on one die. Within the embedded hierarchy it sits above simple logic ICs and below microprocessors: MCU -> 8-bit MCU -> PIC16C family -> Microchip mid-range (14-bit instruction word) OTP devices. The PIC16C62A uses Microchip's enhanced mid-range core with a 14-bit wide instruction word and an 8-bit data path, giving deterministic single-cycle instruction execution and small code size for control loops.
Key features include 3.5KB OTP program memory, 128-byte RAM, 22 I/O pins sharing peripherals such as capture/compare/PWM, an asynchronous serial USART, an 8-bit timer/counter (TMR0), a 16-bit timer/counter (TMR1), and a watchdog timer with on-chip RC oscillator. The static CMOS design draws roughly 15 uA at 5 V / 4 MHz and as little as 1 uA at 3 V / 32 kHz in SLEEP, which makes the part suitable for line-powered and battery-monitored appliances.
Typical applications include appliance control boards, industrial sensor front ends, automotive body electronics (post-1995 designs), HVAC thermostats, remote controls, and small motor control daughter boards. The 10 MHz internal clock and 22 I/O lines deliver enough MIPS to scan key matrices, drive character LCDs, or sequence relays in real time.
When designing with the PIC16C62A, choose an external crystal or ceramic resonator that matches the oscillator configuration bits; OTP programming must be performed at the factory or with a production-grade programmer such as the MPLAB PM3. For new designs Microchip recommends migrating to the flash-based PIC16F62x family, which is pin-compatible with the PIC16C62A but supports in-circuit re-programming.

일반적인 애플리케이션
PIC16C62A-10I/SS 적합 용도: 6 애플리케이션s: Appliance Control Board, HVAC Thermostat, Industrial Sensor Front End, Remote Control Transmitter, Small Motor Control Daughter Board, Automotive Body Electronics (Legacy).
Appliance Control Board
The PIC16C62A-10I/SS fits washing-machine, dishwasher, and microwave control boards because its 22 GPIO pins can scan a 4x5 key matrix, drive a 16-character LCD, and switch triac outputs at 50/60 Hz zero-cross without additional logic. With 3.5KB OTP the firmware fits one-shot appliance code (wash cycles, timer state machines) and the 15 uA active current at 5V/4MHz keeps SMPS heat low. Compared with a discrete logic-board redesign, the MCU integrates debounce, sequencing, and safety lockouts in one 28-SSOP chip, lowering BOM cost. Migration to PIC16F628A-I/SS keeps the same PCB footprint once field updates become necessary.
추천
HVAC Thermostat
In a 24 VAC-powered thermostat the PIC16C62A-10I/SS reads temperature from an external sensor via ADC, drives a 128-segment LCD, and switches a 2 A relay on each temperature delta, all within its 22 GPIO budget. The 1 uA sleep current at 3V/32 kHz keeps battery backup drain negligible, while the 2.5 V to 6.0 V operating range lets the same firmware run from a 3.3 V regulator on energy-harvesting thermostats. The industrial -40C to +85C grade survives attic and outdoor-cabinet mounting. Compared with a 4-bit controller, the 14-bit instruction word delivers faster integer math for PI loops without taxing the 3.5KB code budget.
추천
Industrial Sensor Front End
The PIC16C62A-10I/SS acts as a protocol bridge between a 4-20 mA sensor and a Modbus RTU master in industrial process control. Its USART drives the RS-485 link directly with an external transceiver, while TMR1 captures flow-meter pulses at up to 10 MHz instruction rate. With 128 bytes of RAM the part buffers Modbus frames and 22 GPIO scan eight discrete inputs without an I/O expander. The -40C to +85C industrial range handles factory-floor environments, and the static CMOS design tolerates brown-outs down to 2.0 V for graceful shutdown. Compared with a 32-bit Cortex-M0 alternative, the PIC16C62A consumes one order of magnitude less active current.
추천
Remote Control Transmitter
In IR/RF remote controls the PIC16C62A-10I/SS scans a 5x5 key matrix, encodes commands in RC5 or proprietary protocol, and drives an IR LED through a 38 kHz carrier generated by the CCP PWM, all with margin to spare in the 3.5KB code space. At 3 V from two AAA cells the 1 uA sleep current yields shelf life measured in years; only key-press wakes the MCU via an interrupt-on-change pin. Compared with dedicated encoder ICs, the PIC16C62A adds bidirectional features (e.g., back-channel via the USART) without external glue logic. Migration to PIC16F628A-I/SS keeps the same 28-SSOP PCB for field-reprogrammable universal remotes.
추천
Small Motor Control Daughter Board
The PIC16C62A-10I/SS generates a 4 kHz PWM via CCP to drive a small DC brush motor or unipolar stepper through an H-bridge like the L293D, while TMR1 measures back-EMF tach pulses for closed-loop speed control. The 10 MHz instruction cycle gives 100 ns resolution on commutation timing, fast enough for 1000 RPM stepper microstepping. With 22 GPIO the part also reads end-of-travel limits and a potentiometer-based speed dial. The industrial temperature grade handles motor-mounted enclosures. Compared with discrete 555-based PWM circuits, the MCU enables soft-start, current limit, and stall detection in firmware with no extra hardware.
추천
Automotive Body Electronics (Legacy)
In pre-CAN era body electronics the PIC16C62A-10I/SS drives seat-position memory, mirror fold, and accessory-delay relays with deterministic 14-bit instruction timing. The 22 GPIO scan switch banks and drive MOSFET gates directly, while the USART links to a dashboard display controller. The -40C to +85C industrial temperature range survives cabin environments (under-hood applications require AEC-Q100 parts, which the OTP PIC16C62A does not carry). Compared with relay-only logic, the MCU consolidates timing, interlocks, and diagnostic latches into 3.5KB of OTP code. New designs should migrate to the AEC-Q100 PIC16F628A-I/SS or PIC16F1827-I/SS flash variants.

설계 노트
Estimated: at VDD = 5 V, 10 MHz oscillator (Fosc = 10 MHz, Fcyc = 2.5 MHz due to 4:1 instruction divider), the PIC16C62A draws approximately 2-4 mA active. Add a 100 nF decoupling capacitor within 5 mm of the VDD pin and a 10 uF bulk capacitor near the regulator. In SLEEP mode with WDT enabled the current drops to roughly 5-15 uA; disable WDT in firmware for 1-2 uA sleep current when battery life matters.
Keep the crystal or resonator within 5 mm of OSC1 (pin 16) and OSC2 (pin 15) with a grounded guard ring on the SSOP top layer; route MCLR (pin 27) directly to the reset supervisor with no stubs. The 28-SSOP 0.65 mm pitch requires solder paste inspection - use a 4 mil stencil and reflow with a controlled profile per J-STD-020 to avoid tombstoning on small passive pads near the IC.
Do not assume the PIC16C62A can be re-programmed like a flash part - OTP EPROM can only be written once and erased only by UV exposure on the JW package. Verify CONFIG bits (oscillator, WDT, code protect, brown-out) before committing code to production parts; an incorrect oscillator setting on a virgin OTP device bricks the part. For prototype development use the JW windowed package or migrate to PIC16F62A-I/SS.
