PIC16C62B-04/SS Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and programmable peripherals. Within the broader taxonomy, the PIC16C62B belongs to the 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC hierarchy. OTP variants are programmed once at production or during the first board bring-up and cannot be re-programmed, which differentiates them from Flash-based PIC16F parts and makes them suitable for cost-sensitive, fixed-function, high-volume products where firmware is finalized.
Key features include 22 I/O pins with individually configurable direction registers, a 20 MHz maximum operating frequency across the family (this 04-speed grade is specified for 4 MHz), an operating voltage range compatible with 5V systems, and standard PIC16C6x peripherals including timers, a watchdog timer, and a synchronous/asynchronous serial port. The device uses an external oscillator input. The 28-SSOP package has a 5.30 mm body width and is supplied in tubes for programming houses and production lines.
The architecture is a Harvard-design RISC CPU with 35 single-word instructions and a 14-bit instruction word. Program branches take two cycles; all other instructions are single-cycle, so most code paths run at one instruction per four clock cycles. The 8-bit data path with 128 bytes of RAM targets modest embedded tasks such as sensor reading, simple state machines, keypad scanning, and low-rate serial bridging rather than DSP or graphics workloads.
Typical applications include consumer white goods control boards, industrial sensor interfaces, simple motor drivers, HVAC auxiliary controls, security panel keypads, and battery chargers. The OTP memory is well-matched to mature designs that do not need firmware updates after release. The 28-SSOP footprint is hand-solderable but better suited to reflow processes during PCB assembly.
When designing with the PIC16C62B-04/SS, plan firmware development around OTP constraints: code is finalized and burned in production, so verify all logic on equivalent Flash PIC16F parts or emulator devices before committing to the OTP mask. Use the external oscillator input with a 4 MHz crystal or resonator, and follow Microchip's recommended decoupling and reset-circuit layout guidelines.

Applications typiques
PIC16C62B-04/SS convient pour 6 applications: Consumer White Goods Control Board, Industrial Sensor Interface Module, Security Panel Keypad Controller, HVAC Auxiliary Control Board, Simple Motor Driver Control, Battery Charger Controller.
Consumer White Goods Control Board
The PIC16C62B-04/SS is well suited to consumer white goods such as washing machines, dishwashers, and microwave ovens where the control firmware is finalized at production and never updated in the field. The 3.5KB OTP program memory holds appliance state machines, timer routines, and sensor polling loops for buttons, temperature sensors, and motor relay drivers. The 22 I/O pins accommodate keypad scanning inputs, seven-segment LED drive outputs, and buzzer PWM control. OTP memory keeps BOM cost low compared to Flash parts at million-unit volumes, while the 4 MHz throughput (1 MIPS) easily handles typical appliance control cycles. The 28-SSOP footprint fits compact control boards alongside power relays. Designers should develop on a Flash-based PIC16F627A or PIC16F88x equivalent before committing to the OTP mask for mass production.
Recommandé
Industrial Sensor Interface Module
The PIC16C62B-04/SS functions as a low-cost sensor interface MCU for industrial 4-20 mA loop readers, thermistor signal conditioning, and digital counter modules. Its 8-bit ADC inputs and 22 I/O lines handle multiple analog sensors simultaneously, with the 4 MHz CPU cycle providing 1 MIPS throughput adequate for sample rates up to several kHz. The 128-byte RAM stores conversion buffers and trend history. The PIC16C6x mid-range core's deterministic single-cycle instruction execution suits real-time polling of sensor arrays. The SSOP-28 package fits DIN-rail mounted interface boards. For new designs, Microchip's PIC16F88x family with enhanced ADC and PWM offers improved sensor signal processing while keeping the same SSOP-28 footprint.
Recommandé
Security Panel Keypad Controller
The PIC16C62B-04/SS integrates keypad scanning, LED status indication, and piezoelectric buzzer control in compact security alarm panels. The 22 I/O pins accommodate a 4x4 matrix keypad, multiple zone-status LEDs, and a sounder driver output. OTP memory prevents firmware tampering, providing a security advantage by making it harder to extract code via re-programming interfaces. The 3.5KB program memory holds debounce routines, password comparison logic, and communication framing for the alarm panel's main controller. The 4 MHz instruction rate handles the keypad polling rate of 50-100 Hz typical for entry panels. The SSOP-28 form factor fits slim wall-mount enclosures. Designers targeting new panels should consider Flash-based PIC16F88x for firmware update capability during certification cycles.
Recommandé
HVAC Auxiliary Control Board
The PIC16C62B-04/SS serves as an auxiliary control MCU in HVAC systems for damper actuators, filter status indicators, and auxiliary relay sequencing. Its 8-bit core executes thermostat-style hysteresis control, runtime accumulation, and service-interval counters within 3.5KB of code space. The 128 bytes of RAM hold setpoint values and current operating mode state. The 22 I/O lines interface with thermistor inputs, TRIAC drive outputs for fan speed control, and status LEDs. The 4 MHz throughput handles HVAC sample rates in the 1 Hz range comfortably. OTP memory is appropriate because HVAC firmware rarely changes after UL/CE certification. The SSOP-28 package suits the compact PCB layout of wall-mounted thermostat backplates.
Recommandé
Simple Motor Driver Control
The PIC16C62B-04/SS drives small DC motors and stepper motor indexers in appliance and automation applications. Its PWM output and timer peripherals generate phase-control signals for brushed DC motors at speeds up to several thousand RPM, while 22 I/O pins handle direction logic, end-stop sensor inputs, and enable lines. The 4 MHz instruction rate provides the timing resolution needed for trapezoidal acceleration profiles in stepper indexers. OTP memory suits high-volume motor control products where firmware stabilizes early. The SSOP-28 package mounts near motor driver ICs on compact control PCBs. For development, Microchip recommends prototyping on PIC16F627A before committing to OTP mask charges for production runs.
Recommandé
Battery Charger Controller
The PIC16C62B-04/SS implements charge profile control for small sealed lead-acid and NiMH battery chargers in consumer and backup-power products. The MCU reads battery voltage via ADC, controls charge current through a PWM-driven MOSFET switch, and monitors temperature via thermistor input. The 3.5KB OTP memory holds multi-stage charge algorithms (bulk, absorption, float) and safety timeout routines. The 22 I/O lines interface with status LEDs, mode-select buttons, and the power-stage control signals. OTP memory suits mature designs where charge profiles are well-validated. The SSOP-28 package fits compact charger wall-wart and desktop form factors. Engineers should validate on Flash-based PIC16F627A or PIC16F88x before OTP mask production.

Notes de conception
The PIC16C62B uses One-Time-Programmable (OTP) EPROM, which cannot be erased or re-programmed. Develop firmware on a Flash-based PIC16F627A-04/SS or PIC16F88-I/SS emulator first, then commit the validated hex image to the OTP part only after full qualification. Bit failures or code bugs in OTP parts are non-recoverable, so a single programming error can scrap an entire production batch. Use Microchip's MPLAB PM3 programmer with the correct SSOP-28 socket for production programming.
The PIC16C62B-04/SS operates from a single 5V nominal supply; add a 100 nF decoupling capacitor close to the VDD pin and a bulk capacitor (typically 10 uF) at the board input. The MCLR/VPP pin requires a 10 kohm pull-up to VDD for normal operation; during in-circuit programming, MCLR is driven to the high-voltage VPP level (typically 13V) by the programmer. Failure to isolate the MCLR pull-up from the programming line can cause programming failures or unreliable resets.
Place the external 4 MHz crystal or ceramic resonator as close as physically possible to the OSC1 and OSC2 pins, with the load capacitors returned to ground within a few millimeters. Keep oscillator traces short and routed away from high-current digital outputs and switching power sections to minimize clock jitter. The 28-SSOP package has a 5.30 mm body width and 0.65 mm pitch; reflow profiles should follow JEDEC J-STD-020 with peak temperature below 260C for lead-free or 240C for leaded solder.
