PIC16C62A-04/SS - 8-Bit 4MHz OTP MCU 3.5KB | Microchip
MPN: PIC16C62A-04/SS ✗ Cuối đờiPIC16C62A-04/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. The PIC16C62A belongs to the PIC16C family, which sits within the broader category of 8-bit microcontrollers and ultimately under the umbrella of embedded processors. OTP-based MCUs are widely used in cost-sensitive, low-to-medium volume embedded applications where field reprogrammability is not required and per-unit programming cost is the dominant factor.
Key features include a wide operating voltage range of 2.5 V to 6.0 V, commercial, industrial, and extended temperature grades, and ultra-low power consumption of 15 uA typical at 5 V/4 MHz and 1 uA typical at 3 V/32 kHz. The 28-SSOP package supports surface-mount assembly and is footprint-compatible with the broader PIC16C62/62A/63/64/65/66/67 family. The architecture uses a Harvard design with separate program and data buses, a 14-bit instruction word, and a 35-instruction set that simplifies code generation in assembly or C.
Typical applications include appliance control, HVAC interfaces, simple sensor readouts, automotive body controllers (where qualified), remote controls, and low-cost industrial sensor nodes. Designers select the PIC16C62A-04/SS when the program size is fixed at production time and total system cost must be minimized without sacrificing Microchip's mature toolchain (MPLAB, MPASM, ICD).
When designing, confirm the OTP memory limitation upfront - once programmed, the device cannot be re-programmed in-circuit. For prototyping, use the PIC16F62x equivalent or the PIC16C62A JW windowed version. Plan decoupling and oscillator layout per Microchip AN588.

Ứng dụng tiêu biểu
PIC16C62A-04/SS phù hợp cho 6 Áp dụngs: Appliance Control Panels, HVAC Thermostat Interfaces, Remote Control Transmitters, Simple Sensor Readout Modules, Industrial Sensor Nodes (Non-Safety), Automotive Body Controllers (Legacy).
Appliance Control Panels
The PIC16C62A-04/SS fits appliance control panels where the firmware is fixed at production time and per-unit BOM cost dominates design priorities. Its 3.5 KB OTP memory is sufficient for keypad scanning, LED driving via the 22 I/O lines, and timer-based state machines. The 15 uA active current at 5 V/4 MHz keeps total board power under 100 mW even with all I/O switching, while 1 uA standby at 3 V/32 kHz supports battery-backed real-time clock modes in unplugged washers or microwaves.
Được đề xuất
HVAC Thermostat Interfaces
In HVAC thermostat interfaces, the PIC16C62A-04/SS serves as the user-interface controller, scanning temperature sensors, driving LCD or seven-segment displays, and managing relay outputs for compressor, fan, and heat stages. The 4 MHz instruction throughput handles multi-zone scheduling logic and debouncing without external glue logic. The wide 2.5-6.0 V operating range allows direct connection to 5 V wall adapters and 3.3 V battery backup rails.
Được đề xuất
Remote Control Transmitters
For IR or RF remote control transmitters, the PIC16C62A-04/SS handles keypad matrix scanning and protocol encoding (RC5, NEC, or proprietary) within its 3.5 KB OTP budget. The 22 I/O lines support up to an 8x8 matrix or multi-button plus rotary encoder inputs. At 3 V operation the 1 uA standby current enables multi-year battery life in shelf applications - the OTP memory is acceptable because remote firmware is locked at production.
Được đề xuất
Simple Sensor Readout Modules
Sensor readout modules with digital or analog front-ends (temperature, humidity, pressure) use the PIC16C62A-04/SS for ADC sampling, linearization, calibration storage, and digital output formatting. The 128-byte RAM supports modest moving-average filters, while the 22 I/O accommodate SPI or I2C sensor buses plus isolated digital outputs. The OTP memory locks calibration constants and lookup tables at production.
Được đề xuất
Industrial Sensor Nodes (Non-Safety)
Non-safety industrial sensor nodes deploy the PIC16C62A-04/SS to read 4-20 mA or 0-10 V transducer outputs, perform signal conditioning in firmware, and report results over RS-232 or simple GPIO. The wide operating temperature range and 5 V tolerance allow deployment in factory floor cabinets. Designers favor OTP memory when firmware revision control is enforced through hardware BOM, eliminating field-update attack surface.
Được đề xuất
Automotive Body Controllers (Legacy)
In legacy automotive body controllers (window lifts, mirror adjusters, simple lighting controllers), the PIC16C62A-04/SS is used where AEC-Q100 qualification is not strictly mandated or where the design was qualified before AEC-Q100 was required. The 22 I/O lines drive relays and read switches directly, and the OTP memory locks firmware per vehicle variant. For new automotive designs, Microchip recommends PIC16F628A-I/SS (AEC-Q100 grade 1) in the same footprint.

Ghi chú thiết kế
PIC16C62A-04/SS uses OTP (one-time-programmable) EPROM memory, so a programming error permanently bricks the device. Always program production volumes using a verified hex file generated from MPLAB IDE with a stable programmer (Microchip PICSTART Plus, MPLAB PM3, or ICD2/3 for emulation). Estimate a 2-5% programming yield loss into your BOM for OTP-based PIC16C6x designs. For prototypes, use the JW windowed variant or the Flash-based PIC16F62x equivalent in the same 28-SSOP footprint.
PIC16C62A-04/SS draws 15 uA typical at 5 V/4 MHz and 1 uA typical at 3 V/32 kHz per the datasheet. Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 20) with a short trace to VSS (pin 19). For battery-backed applications using the watchdog and sleep modes, the brown-out reset and power-on reset configurations must be set via configuration fuses during programming; verify these in your MPLAB project settings before code generation.
The 28-SSOP package requires careful PCB layout: keep the crystal or resonator within 5 mm of OSC1 (pin 9) and OSC2 (pin 10), with ground guard traces on both sides per Microchip AN588 (PIC16C6x oscillator layout guidelines). Estimated: at 4 MHz, stray capacitance above 20 pF on OSC1/OSC2 can shift the oscillator frequency by 2-5%, potentially violating timing budgets for UART or PWM peripherals. Use a four-layer PCB with a dedicated ground plane if operating in electrically noisy industrial environments.
