PIC16C62AT-10/SS Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. Within the broader semiconductor taxonomy, the PIC16C62A sits as a member of Microchip's PIC16 mid-range 8-bit MCU family, which itself belongs to the larger PICmicro 8-bit microcontroller category and the wider universe of microcontrollers and embedded processors. The PIC16C6x family is the OTP-programmable predecessor of the Flash-based PIC16F6x series, sharing the same core instruction set, peripheral set, and pinout so legacy designs can move from windowed/OTP to flash without code changes.
Key features include a Harvard RISC architecture with only 35 single-word instructions, a hardware 8-bit timer/counter (TMR0) with 8-bit prescaler, a 16-bit timer/counter (TMR1), an 8-bit Capture/Compare/PWM (CCP) module, an analog comparator, a Watchdog Timer with its own on-chip RC oscillator, and a 5-channel 8-bit A/D converter. The CMOS design delivers low power consumption with typical standby current in the microamp range, making it suitable for both battery and line-powered applications.
Technically, the PIC16C62A uses a 14-bit instruction word and a separate 8-bit data path, enabling single-cycle instruction fetch except for branches which take two cycles. The 22 I/O pins are arranged on PORTB (8 pins) and PORTC (8 pins) plus 6 additional pins on PORTA. The ADC supports up to 5 analog inputs and operates from the device VDD, while the analog comparator provides rail-to-rail input capability for low-side or high-side sensing tasks.
Typical applications include appliance control, automotive body electronics (non-AEC-Q100), industrial control logic, security and alarm panels, sensor signal conditioning, low-end data loggers, and consumer electronics requiring reliable 8-bit processing. The wide commercial temperature range and proven PIC16C core make it well suited to cost-sensitive designs that have already been qualified on this part number.
When designing with this part, note that the OTP memory is one-time programmable and cannot be erased; code must be fully verified before committing. For new designs, Microchip generally recommends the flash-based PIC16F62x or PIC16F88x family as the modern equivalent; the PIC16C62AT-10/SS is best reserved for sustaining legacy production.

Typical Applications
PIC16C62AT-10/SS is suitable for 6 applications: Appliance Control Boards, Security and Alarm Panels, Industrial Sensor Conditioning, Automotive Body Electronics (Non-Safety), Consumer Electronics Remote Controls and HMI, Data Logging and Standalone Instrumentation.
Appliance Control Boards
The PIC16C62AT-10/SS is well suited to legacy appliance control designs including washing machines, dishwashers, microwave ovens, and HVAC controls. The 10 MHz PIC16C core executes the sensor-polling and relay-actuation loops with sufficient margin, while the 8-bit ADC reads thermistor, water level, and pressure sensor inputs. The 22 I/O pins drive relay banks, triac triggers, and LED indicators. The wide 5V tolerance simplifies integration with TRIAC optocouplers, and the commercial temperature range covers kitchen and laundry environments.
Recommended
Security and Alarm Panels
For alarm control panels, PIR sensor conditioning, and keypad scanners, the PIC16C62AT-10/SS provides the deterministic PIC16C core needed for time-critical loop supervision. The analog comparator enables window-comparator based PIR signal processing, while the 8-bit ADC digitizes battery voltage and zone loop current. The brown-out reset ensures clean restart on power dips, and the watchdog timer protects against firmware lockup in unattended panels. The 28-pin SSOP footprint is well suited to compact wall-mount enclosures.
Recommended
Industrial Sensor Conditioning
Industrial sensor front-ends and slow control loops benefit from the PIC16C62AT-10/SS combination of an 8-channel-capable ADC (5 active channels), analog comparator, and 10 MHz CPU core. The device reads 4-20 mA loop receivers via shunt voltage, conditions RTD or thermocouple signals with external amplifiers, and drives isolated output stages. The hardware USART-less design relies on software bit-banging for field buses, making this MCU best for asynchronous polling loops at baud rates up to 9600 bps.
Recommended
Automotive Body Electronics (Non-Safety)
The PIC16C62AT-10/SS is widely deployed in non-safety automotive body electronics such as window lift modules, seat controllers, mirror adjusters, and lighting controls, although it is NOT AEC-Q100 qualified. The 5V supply tolerates the 12V battery bus after regulation, and the PIC16C core handles LIN-like software-UART bit-banging for body control networks. For new automotive designs, Microchip recommends AEC-Q100 qualified PIC16F or dsPIC variants in the same SSOP-28 footprint.
Recommended
Consumer Electronics Remote Controls and HMI
In consumer remote controls, small appliances, and HMI panels, the PIC16C62AT-10/SS delivers responsive button scanning and LED feedback at very low cost. The 22 I/O accommodate matrix keypads, rotary encoders, and 7-segment or LCD multiplexing. Low-power CMOS standby modes extend battery life in remote-style products, and the SSOP-28 package fits inside handheld enclosures. The OTP memory is acceptable for high-volume consumer products where firmware is locked.
Recommended
Data Logging and Standalone Instrumentation
Low-speed standalone data loggers benefit from the PIC16C62AT-10/SS combination of a 10 MHz CPU, 8-bit ADC, and 22 I/O. The device samples sensor inputs at intervals controlled by TMR1, writes records to external EEPROM or FRAM via bit-banged I2C, and toggles status LEDs. Brown-out reset and watchdog timer are essential for unattended logger reliability. The SSOP-28 footprint keeps the design compact for portable logger enclosures.

Key Differentiators
- Higher speed grade versus lower-cost alternative (vs PIC16C62A-04/SS)
- Wider temperature range than commercial-only competitor (vs PIC16C62A-10/SS)
- Field-reprogrammable memory type vs OTP (vs PIC16F627A-I/SS)
Design Notes
Estimated: OTP memory cannot be erased once programmed. Before programming production units, fully verify firmware on a flash-based equivalent such as PIC16F627A-I/SS to avoid bricking inventory. A code-size check (sum of instruction words vs 2048 available) and a checksum verify step must be included in the production programming flow. Carry out at least 100 engineering-trial units to validate end-customer use cases before committing OTP stock.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 20) and a bulk 10 uF tantalum or ceramic capacitor near the VSS pin (pin 10). Add a 10 kohm pull-up on MCLR/VPP (pin 1) to VDD with a 100 nF cap for noise immunity; do not float MCLR or the part will reset intermittently. Brown-out reset should be enabled in the configuration word to guarantee clean startup on power dips.
The 28-pin SSOP package has 0.65 mm pitch pads and a thermal pad slug; route power traces with at least 0.3 mm width and avoid routing noisy signals under the IC. Keep the crystal or resonator within 10 mm of OSC1/OSC2 (pins 8-9) with short, symmetric traces and a guard ground to prevent jitter. Maintain a continuous ground plane on the bottom layer and stitch vias around the IC perimeter for EMI suppression.
Compliance Information
PIC16C62A family is generally non-RoHS due to original OTP lead finish; some factory-lot variants may carry RoHS finish and must be confirmed at order. Not AEC-Q100 qualified; for automotive designs use AEC-Q100 PIC16F or dsPIC equivalents.
