PIC16C662-10E/PT - 8-Bit 10MHz 7KB OTP MCU 44-TQFP | Microchip
MPN: PIC16C662-10E/PT ✓ فعالPIC16C662-10E/PT نمای کلی
An OTP (One-Time Programmable) microcontroller is a class of non-volatile programmable logic device that can be written only once after manufacture - a cost-optimized solution for high-volume, mature products where field firmware updates are not required. Within the broader taxonomy, OTP MCUs sit between mask-ROM devices (lowest cost, fixed code) and Flash-based MCUs (re-programmable); they share the same PIC16C core architecture, instruction set, and peripheral set as their Flash equivalents. PIC16C6x parts are widely used in industrial control, appliance, and automotive subsystems where production firmware is frozen.
Key features of the PIC16C662-10E/PT include 33 digital I/O pins, an integrated analog comparator, a watchdog timer, a 8-bit timer/counter (Timer0) and an 8-bit timer/counter with prescaler (Timer1), plus capture/compare/PWM modules. The device also supports an external oscillator, low-power SLEEP mode, and in-circuit serial programming (ICSP) via the ICSP pins. Operating voltage ranges from 3.0 V to 6.0 V (per the PIC16C66x datasheet family).
Typical applications include industrial control panels, white-goods motor control, security keypads, HVAC controllers, and automotive body-electronics modules. The extended temperature range and EPROM-based memory make this part a robust choice for long-lifecycle, fixed-code designs. Engineers designing with this device should review the PIC16C66x datasheet family for oscillator configuration, current consumption per MHz, and the I/O pin mapping for the 44-TQFP package.

کاربردهای معمول
PIC16C662-10E/PT مناسب است برای 6 کاربردs: Industrial Control Panels, White-Goods Motor Control, Security Keypads and Access Panels, HVAC Climate Controllers, Automotive Body Electronics, Appliance User Interface Boards.
Industrial Control Panels
The PIC16C662-10E/PT fits industrial control panels because its 7 KB OTP, 33 I/O pins, and Extended -40 C to +125 C temperature rating support fixed-function machine interfaces without firmware updates. The integrated analog comparator and CCP/PWM modules drive relays, opto-isolated outputs, and triac phase-control circuits typical of PLC-style panels. Compared with Flash PIC16F parts, OTP keeps unit cost low for high-volume panel builders.
پیشنهادی
White-Goods Motor Control
The PIC16C662-10E/PT is well suited for washing machines, dishwashers, and refrigerator control boards because its 10 MHz instruction cycle, two 8-bit timers, and CCP PWM module provide deterministic speed control of universal AC motors and triac-driven pumps. The Extended -40 C to +125 C range survives the thermal envelope near compressor housings. OTP programming keeps BOM cost under one dollar at high volumes.
پیشنهادی
Security Keypads and Access Panels
The PIC16C662-10E/PT drives 4x4 matrix keypads and credential readers in alarm panels and access-control terminals where the 33 I/O pins handle keypad scanning, status LEDs, buzzer drivers, and a serial link to the central controller. Its on-chip analog comparator monitors tamper switches without external op-amps, and the watchdog timer resets the controller if firmware locks up - critical for unattended security hardware.
پیشنهادی
HVAC Climate Controllers
The PIC16C662-10E/PT handles thermostat loops and HVAC damper/valve actuation because its analog comparator plus 10-bit-capable RC I/O measure thermistor temperature without external ADC, while the CCP module generates PWM for proportional valve control. The Extended temperature grade lets the PCB sit in unconditioned equipment closets, and OTP eliminates firmware-update liability in fielded units.
پیشنهادی
Automotive Body Electronics
The PIC16C662-10E/PT appears in body-electronics modules such as seat controllers, mirror adjusters, and interior lighting where Extended -40 C to +125 C operation, 33 I/O, and OTP cost structure fit production volume. The integrated watchdog and analog comparator support load-dump and short-circuit protection. Note this part is not AEC-Q100 qualified - for AEC-Q100 programs choose Microchip's automotive PIC16F catalog.
پیشنهادی
Appliance User Interface Boards
The PIC16C662-10E/PT powers microwave oven panels, dishwasher displays, and oven user interfaces, where it scans 7-segment or LCD-style indicators, drives piezo buzzers, and reads capacitive touch via the analog comparator. Extended temperature operation survives the heat of adjacent cooktops and steam, while the 7 KB OTP is enough for full menu state machines.

یادداشت‌های طراحی
OTP (One-Time Programmable) devices can only be programmed once - the entire firmware image must be verified before the final write cycle. Use MPLAB X IDE with a known-good HEX file and a fresh, unprogrammed PIC16C662-10E/PT for production. A programmed OTP that fails final test is scrap, so factory programming lines should run an initial verification pass on a sample before committing the full lot.
Place the 100 nF VDD bypass capacitor within 5 mm of pin 11 (VDD) and the VSS decoupling on pin 12, with the trace length kept under 3 mm to minimize switching noise. For the 44-pin TQFP (10x10 mm), route MCLR (pin 1) away from the OSC1/OSC2 (pins 13/14) clock traces to prevent false resets during high-frequency oscillator transitions. Keep the ICSP PGC/PGD traces (RB6/RB7) short and away from motor-drive PWM outputs to avoid programming glitches.
Estimated: at 10 MHz clock with all peripherals active, the PIC16C662-10E/PT draws roughly 5 mA typical at 5 V. Power dissipation is therefore approximately 25 mW worst-case, well below the TQFP thermal limit, so no heatsink or thermal-via array is required. Add a bulk 10 uF electrolytic plus 100 nF ceramic on the board power rail to handle inrush from relay coils and motor loads.
