PIC16C62B-04/SP 概要
An 8-bit OTP microcontroller is a single-chip computer that integrates a CPU, non-volatile program memory (one-time-programmable EPROM in this case), volatile data memory, and peripheral interfaces into one package. OTP means each cell can be programmed once, after which the bit pattern is permanent. Within the broader taxonomy, this device is part of the PIC16C family -> mid-range 8-bit PIC microcontrollers -> 8-bit MCU -> microcontroller -> embedded computing category. The "04" speed suffix indicates the maximum oscillator frequency of 4MHz, equivalent to roughly 1 MIPS of instruction throughput, with one instruction cycle per four clock periods.
Key features of the PIC16C62B-04/SP include the Harvard architecture with separate program and data buses, a 14-bit wide instruction word optimized for compact code, a low-power CMOS process achieving 15 uA typical current at 5V/4MHz and 1 uA typical at 3V/32 kHz, integrated peripherals such as capture/compare/PWM, an 8-bit timer/counter, a watchdog timer, and a synchronous serial port (SSP). The 22 I/O pins can source/sink up to 25 mA each, making them capable of directly driving LEDs and small relays without buffer transistors.
The PIC16C62B-04/SP uses the Microchip mid-range RISC core with 35 single-cycle instructions, two stack levels for subroutine nesting, and interrupt handling with hardware context save. The integrated analog comparator, programmable brown-out reset, and selectable oscillator options (RC, LP, XT, HS) provide flexibility across cost-sensitive and low-power applications. The 28-SPDIP package is 0.300 inch (7.62 mm) wide, making it compatible with standard 0.1 inch pitch through-hole prototyping boards and existing PIC16C6x sockets.
Typical applications for the PIC16C62B-04/SP include appliance control boards, industrial sensor interfaces, low-end remote controls, security keypads, automotive body controllers (industrial grade), and embedded data acquisition nodes. The combination of OTP memory, low quiescent current, and 22 GPIO pins makes this device well-suited for high-volume cost-sensitive products where code stability is verified before programming.
When designing with the PIC16C62B-04/SP, ensure the MCLR reset pin has a proper pull-up and the VDD pins are adequately decoupled with 0.1 uF ceramic capacitors. Because this is an OTP device, code must be fully validated before the production programming step; the device cannot be reprogrammed or erased. Engineers should use MPLAB X IDE and a PM3 programmer for development and production programming.

主な用途
PIC16C62B-04/SP の用途: 7 件s: Appliance Control Boards, Industrial Sensor Interface Modules, Remote Control and Keypad Decoders, Automotive Body Controllers, Security and Access Control Panels, Embedded Data Acquisition Front-Ends, Toy and Hobby Electronics.
Appliance Control Boards
The PIC16C62B-04/SP is well suited for white-goods and small-appliance control boards (washing machines, microwave ovens, coffee makers, rice cookers) where the OTP memory locks the firmware at production and the 22 I/O pins drive 7-segment displays, keypads, relays, and triac interfaces directly. Its 4MHz CPU delivers 1 MIPS, sufficient for sensor polling, button debouncing, and triac zero-crossing control. The 25 mA per-pin sink/source current can drive LED indicators and small relays without buffer transistors. Industrial temperature variants (PIC16C62B-04I/SP) extend the operating range to -40C to +85C, covering the thermal envelope of kitchen and laundry environments.
おすすめ
Industrial Sensor Interface Modules
For 4-20 mA loop-powered sensor transmitters and discrete sensor interface boards, the PIC16C62B-04/SP provides the right balance of analog comparator, 8-bit ADC-less digital I/O, and USART for serial data output. The 3.5KB OTP program memory holds calibration tables, linearization routines, and Modbus-RTU or proprietary protocols. The wide 2.5V to 6.0V supply range accepts 5V industrial rails and battery configurations. The 1 uA sleep current at 3V/32 kHz makes it viable for battery-backed sensor nodes that spend most of their time in sleep mode, waking periodically to take readings.
おすすめ
Remote Control and Keypad Decoders
The PIC16C62B-04/SP serves as the decoding brain in IR remote controls, RF key fobs, and wired security keypads where cost-per-unit is critical and the OTP memory is programmed once at the factory. Its USART module can interface with RF transceiver chips for sub-GHz remote control, while the 22 GPIO pins scan 4x4 or 4x5 key matrices directly. The capture/compare/PWM (CCP) module generates IR carrier frequencies (typically 38 kHz) for remote-control transmitters. Low sleep current of 1 uA extends battery life in handheld units to several years on a single coin cell.
おすすめ
Automotive Body Controllers
In non-safety automotive body-electronics such as interior lighting controllers, seat-adjustment keypads, mirror-fold modules, and HVAC flap actuators, the PIC16C62B-04/SP and its industrial temperature sibling are widely deployed. The automotive-grade 12V bus is regulated down to 5V for the MCU, and the 22 high-current GPIO pins can drive small motors, LEDs, and solenoids directly. The integrated watchdog timer and brown-out reset provide the reliability needed for under-hood and in-cabin environments. Note: for AEC-Q100 qualified automotive designs, Microchip recommends the PIC16F628 or PIC16F1939 family instead.
おすすめ
Security and Access Control Panels
Security alarm panels, access-control keypads, and intrusion-detection sensors leverage the PIC16C62B-04/SP for its low cost, OTP memory security (firmware cannot be reverse-engineered via reprogramming), and integrated USART for communication with central stations. The 3.5KB program memory stores zone configuration, event-logging routines, and encryption-friendly look-up tables. The watchdog timer and brown-out reset ensure the panel recovers gracefully from power glitches. The 28-SPDIP package through-hole construction is favored for production-line hand-soldering and field-replaceable installations.
おすすめ
Embedded Data Acquisition Front-Ends
Low-speed embedded data-acquisition front-ends for HVAC monitoring, energy-meter pulse counting, and process-control signal conditioning use the PIC16C62B-04/SP as a glue controller between analog front-ends and serial back-haul links. The 8-bit timer/counter captures pulse-train inputs from flow meters and electricity meters, while the USART transmits aggregated readings via RS-485 to a central controller. The 2.5V-6.0V supply range accepts 3.3V and 5V rails. OTP memory prevents firmware tampering, important in metering and regulatory-compliance applications where measurement algorithms must remain immutable.
おすすめ
Toy and Hobby Electronics
Cost-sensitive consumer toys, hobby electronics kits, educational microcontroller platforms, and electronic dice/cube games use the PIC16C62B-04/SP because the OTP memory is the cheapest non-volatile option for high-volume production runs. The 22 I/O pins can drive LED matrices, servo motors, and small DC motors directly. The 4MHz CPU is sufficient for sequential LED animations, sound playback via PWM, and simple game logic. The through-hole 28-SPDIP package is ideal for hobbyist breadboarding and educational kits, where users do not need to reflash the device.

設計ノート
The PIC16C62B-04/SP uses OTP (one-time-programmable) memory that cannot be erased or rewritten after programming. Any firmware bug, lock-bit misconfiguration, or improperly-set configuration word (especially the watchdog, brown-out, or oscillator mode bits) will result in a bricked device requiring a new chip. Always validate the complete firmware image and configuration word in a socketed prototype before committing to production programming with the PM3 or MPLAB PM3. Consider migrating to PIC16F628-04/P for new designs to gain ICSP reprogrammability.
Power supply decoupling is critical: place a 0.1 uF ceramic capacitor as close as physically possible to each VDD/VSS pair (pins 11/12 on the PIC16C62B-04/SP), with trace length under 3 mm. Add a 10 uF bulk tantalum or aluminum electrolytic capacitor at the regulator output. For battery-powered designs, the brown-out reset (BOR) should be enabled in the configuration word to prevent code execution at VDD below the safe threshold (typically 4.0V for 4MHz operation). Sleep current of 1 uA typical at 3V/32 kHz requires careful leakage analysis of any external pull-up resistors on the MCLR and port pins.
The 28-SPDIP package has 0.100 inch (2.54 mm) pin pitch and 0.300 inch (7.62 mm) row spacing. When laying out the PCB, keep the MCLR pull-up resistor (typically 10 kohm) within 5 mm of pin 1, and place the ICSP header (if any) on a separate programming connector. The OSC1/OSC2 traces should be kept short (under 10 mm) and routed away from switching signals to avoid EMI injection into the clock. If using a crystal oscillator, place load capacitors (typically 15-33 pF) immediately adjacent to the crystal pins with a ground pour underneath.
コンプライアンス情報
Through-hole 28-SPDIP package contains lead (Pb) and is NOT RoHS compliant. For RoHS-compliant equivalent, use PIC16C62B-04I/SS or PIC16C62B-04/SO in SOIC-28 package. No AEC-Q100 automotive qualification; choose PIC16F628 for AEC-Q100 requirements.
