PIC16C62BT-04I/SS - 8-Bit 4MHz OTP MCU 3.5KB | Microchip
MPN: PIC16C62BT-04I/SS ✓ Hoạt độngPIC16C62BT-04I/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and programmable I/O peripherals. The PIC16C62B family belongs to the PIC16C mid-range lineup, which sits hierarchically under Microchip's 8-bit MCU portfolio (PIC10/12/16/24) and the broader class of CMOS RISC controllers. Unlike Harvard-architecture competitors, the PIC16C series uses a 14-bit instruction word with only 35 single-word instructions to learn, all single-cycle except program branches that take two cycles. This makes the PIC16C62B family attractive for cost-sensitive, deterministic control tasks where code density and predictable interrupt latency are valued over raw throughput.
Key features include a fully static design supporting DC to 20MHz operation, a wide operating voltage range from 2.5V to 6.0V across the family, low-power consumption of 15 uA typical at 5V/4MHz and 1 uA typical at 3V/32 kHz, and three timer/counter modules (Timer0, Timer1, Timer2). The 22 I/O ports can source/sink 25 mA per pin, enabling direct LED drive without external transistors. The device includes an analog comparator module, a USART for serial communication, and a Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation.
Technically, the PIC16C62BT-04I/SS uses Microchip's classic EPROM/ROM process with windowed (JW) variants for prototype development. The 4MHz speed grade (suffix -04) targets DC to 4MHz instruction execution, while family members extend to 20MHz. The integrated Power-on Reset, Brown-out Reset, and Power-up Timer reduce external component count. Industrial temperature range is -40C to +85C.
Typical applications include motor control, security systems, appliance control, automotive body electronics (non-safety), and industrial automation. This part is suitable for brownfield designs requiring 28-pin SSOP with OTP memory and PIC mid-range instruction set compatibility.
When designing with the PIC16C62BT-04I/SS, verify the EPROM window vs OTP trade-off against your production volume. The -04 speed grade limits instruction throughput to 4 MIPS maximum, and you may need a faster grade (e.g., -20) for time-critical loops.

Ứng dụng tiêu biểu
PIC16C62BT-04I/SS phù hợp cho 6 Áp dụngs: Industrial Motor Control, Security and Alarm Panels, White Goods / Appliance Control, Automotive Body Electronics (Non-Safety), HVAC Control Modules, Lighting Control and DMX.
Industrial Motor Control
The PIC16C62BT-04I/SS suits small DC motor and stepper control loops in industrial equipment. Its 22 I/O pins (each capable of 25 mA source/sink) directly drive H-bridge gate signals, encoder inputs, and limit-switch sensing without external buffers. The 4MHz instruction rate delivers 1 MIPS, adequate for trapezoidal commutation at moderate RPM. Industrial -40C to +85C operation tolerates control cabinet environments.

Security and Alarm Panels
The PIC16C62BT-04I/SS fits hard-wired security control panels where deterministic response time is critical. Its 35 single-word PIC instructions execute predictably in 1 cycle (4 clocks), enabling tight interrupt latency for sensor polling. Brown-out Reset and Watchdog Timer ensure the panel recovers from brownouts or firmware lockups. OTP memory secures the firmware against external read-back, important for anti-tamper requirements.
Được đề xuất
White Goods / Appliance Control
The PIC16C62BT-04I/SS is well-suited to washing machine, dishwasher, and microwave oven controllers. The 22 I/O pins handle keypad scanning, LED/relay drivers, and triac-firing outputs. Wide 4.0-5.5V supply tolerance tolerates rectified mains-rail variation. Low-power modes (15 uA at 4 MHz, 1 uA at 32 kHz) support standby power targets. Industrial temp range covers behind-panel thermal environment.
Được đề xuất
Automotive Body Electronics (Non-Safety)
The PIC16C62BT-04I/SS drives non-safety body modules like seat controllers, mirror adjusters, and accessory timers. The 4 MHz MIPS, 22 I/O pins, and PIC 40C instruction compatibility suit LIN-bus slaves and PWM-driven actuators. Brown-out Reset is critical for crank-cold-start transients. Industrial temp range covers cabin-mounted electronics. (Not AEC-Q100 qualified - choose PIC16F equivalent for AEC-Q100 designs.)

HVAC Control Modules
The PIC16C62BT-04I/SS controls thermostat and HVAC zone dampers. Its analog comparator enables thermistor sensing without an external ADC, lowering BOM cost. The 22 I/O drive port expansion pins fan relay triac drivers, valve actuators, and LCD segment drivers. OTP locks firmware to prevent unauthorized HVAC reconfiguration. Industrial temperature grade covers attic/equipment-room installations.
Được đề xuất
Lighting Control and DMX
The PIC16C62BT-04I/SS handles architectural lighting and DMX-512 receiver nodes. The integrated USART supports DMX-512 (250 kbaud) receive directly, freeing CPU cycles for fade math. PWM outputs (via Timer2) generate 8-bit dimming without external logic. The 22 I/O drive port pins control 0-10V dimmers, relay packs, and status LEDs. Industrial temp range covers indoor fixtures.

Ghi chú thiết kế
The PIC16C62BT-04I/SS draws approximately 15 uA at 5V/4MHz active and 1 uA typical at 3V/32 kHz standby. Decouple VDD with a 100 nF ceramic capacitor placed within 5mm of pin 27, plus a bulk 10 uF tantalum at the regulator output. Brown-out Reset is enabled by clearing the BODEN bit in the configuration word to detect supply droops below 4.0V.
The 28-SSOP package has 0.65 mm pitch - route signals on a 0.1 mm grid with at least 8 mil traces and 8 mil spaces. Place the decoupling capacitor on the same layer as the MCU to minimize via inductance. Keep the OSC1/OSC2 traces short and surrounded by ground pour for EMI suppression. SSOP leads are fragile; use proper footprint with adequate solder mask slivers.
Do not confuse the -04 grade (4 MHz) with the -20 grade (20 MHz) - the configuration word is identical, but the timing budget differs by 5x. When programming OTP, ensure VPP (pin 1, MCLR/VPP) reaches 13V during the programming pulse; insufficient VPP causes verify errors. The 'T' suffix on T-suffix variants denotes Tape and Reel packaging, not a silicon variant.
Each PORTB and PORTA pin can source or sink 25 mA, but the total port current should not exceed 200 mA across all pins simultaneously. For PWM-controlled loads, use Timer2 with a postscaler to generate 8-bit PWM at typical 1-10 kHz rates. The analog comparator shares pins with PORTA, so configure analog functions before enabling digital I/O on those pins.
