MPN: PIC16C622T-04E/SS ✗ Cuối đờiPIC16C622T-04E/SS Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces into one package. Within the broader taxonomy of semiconductors, an MCU belongs to the digital logic / microcontroller class, and the PIC16C series occupies the mid-range 8-bit tier of Microchip's PIC portfolio, offering RISC architecture with a 14-bit instruction word optimized for compact, deterministic control code. OTP program memory allows the device to be programmed once during manufacturing, which lowers unit cost versus flash-based MCUs and is well suited to high-volume, fixed-function consumer and industrial products.
Key features of the PIC16C622T-04E/SS include the 14-bit instruction set, 35 single-word instructions (most single-cycle), a hardware multiplier, Brown-out Detect/Reset, Power-On Reset (POR), Watchdog Timer (WDT) with its own on-chip RC oscillator, an analog comparator, a programmable voltage reference, and a Capture/Compare/PWM (CCP) module. The wide 2.0V to 6.0V supply range allows battery-backed or 5V-rail designs, and the 20-SSOP outline saves board area versus a 20-pin PDIP alternative.
Architecturally, the PIC16C622 uses a Harvard bus with separate program and data paths and a 2-stage pipeline. On-chip peripherals include a 16-bit timer/counter (TMR1) optionally operable in sleep mode with an external crystal, an 8-bit timer/counter (TMR0) with 8-bit prescaler, and synchronous serial port (SSP) for SPI / I2C master-slave communication. Two analog comparators with a programmable reference voltage block add signal-conditioning capability without external op-amps.
Typical applications include white-goods and appliance controls, low-end remote controls, sensor signal conditioning with on-chip comparators, simple sensor-front-end nodes, battery chargers, automotive body controllers, lighting ballasts, and industrial control subsystems where cost dominates over reprogrammability. The extended temperature grade extends use to under-hood and outdoor enclosures.
When designing with this device, ensure that the chosen emulator/programmer (PICMASTER, MPLAB PM3, or PRO MATE II) supports the PIC16C62x OTP windowed/extended parts, and budget for a 25 mA / 6 V absolute maximum on VDD plus proper decoupling with 0.1 uF + 10 uF bulk capacitors. Pin-compatible PIC16C62x family members exist in the same 20-SSOP package, simplifying last-time buys and PCB reuse.

Ứng dụng tiêu biểu
PIC16C622T-04E/SS phù hợp cho 6 Áp dụngs: White Goods and Appliance Control, Automotive Body Electronics, Industrial Sensor Front-Ends, Lighting Ballast and LED Driver Controllers, Remote Control and Consumer IR, Battery Chargers and Power Tools.
White Goods and Appliance Control
The PIC16C622T-04E/SS fits washing-machine, dishwasher, and refrigerator control boards because its 3.5 KB OTP holds a complete state-machine for motor sequencing, sensor polling, and user-interface handling while 128 bytes of RAM covers real-time variables. The two on-chip analog comparators accept 50/60 Hz zero-crossing signals for triac timing without external op-amps, saving both board space and BOM cost. Brown-out Reset and Power-On Reset protect the MCU during the brown-outs common in compressor-driven appliances. The -40 C to +125 C extended grade handles under-cabinet heat and motor-driver proximity.

Automotive Body Electronics
Body controllers for seat adjusters, mirror modules, lighting clusters, and HVAC blend doors are dominated by 8-bit MCUs, and the PIC16C622T-04E/SS targets these directly through its -40 C to +125 C extended grade and 2.0-6.0 V supply, which tolerates cranking transients on the 12 V automotive bus when fed through a pre-regulator. The 13 GPIO lines drive relays, LED strings, and H-bridge enable pins directly. Hardware WDT with its own RC oscillator resets the controller when firmware locks up under EMI stress. Designers should confirm that PIC16C62x in 20-SSOP is qualified by the automaker's component acceptance procedure.

Industrial Sensor Front-Ends
Sensor transmitters for pressure, level, flow, and temperature often need a microcontroller that can run 4-20 mA loop-powered or 24 V industrial-bus powered, condition analog signals, run a PID-style control loop, and drive an HART or MODBUS interface. The PIC16C622T-04E/SS's 13 GPIO, two analog comparators with programmable reference, and 16-bit TMR1 with capture register fit 4-20 mA loop-smart sensors where the OTP memory locks the calibration coefficients at programming. The wide 2.0-6.0 V supply allows the same MCU to be used across 3.3 V and 5 V sensor variants.

Lighting Ballast and LED Driver Controllers
Fluorescent and HID ballasts use 8-bit MCUs to manage lamp warm-up, dimming, power-factor correction, and fault detection. The PIC16C622T-04E/SS runs the ballast state machine at 4 MHz with deterministic instruction timing, while its Capture/Compare/PWM module generates the lamp-drive switching waveform directly. The Brown-out Reset trips cleanly when the rectified mains drops below regulation. The 20-SSOP footprint simplifies high-density ballast PCB layouts where the controller sits next to the power MOSFETs. Extended temperature supports enclosed luminaire environments that exceed 70 C ambient.
Được đề xuất
Remote Control and Consumer IR
Universal remote controls and simple IR transceivers need a low-cost, low-power MCU that runs a fixed IR protocol stack. The PIC16C622T-04E/SS's 3.5 KB OTP accommodates complete RC5/RC6 or NEC protocol decoders plus user-button matrix scanning on the 13 GPIO. The 16-bit TMR1 captures IR carrier edges accurately, while the SSP block talks to external EEPROM for learned-code storage. Sleep current is well under 1 uA with WDT running, supporting multi-year battery life on a coin cell.
Được đề xuất
Battery Chargers and Power Tools
Cordless-drill and battery-charger controllers need an MCU that runs a charge algorithm (CC/CV for Li-ion, delta-V for NiMH, timer for SLA) and monitors pack thermistors. The PIC16C622T-04E/SS uses its on-chip analog comparators to detect end-of-charge voltage and temperature cutoffs without external op-amps. Brown-out Reset and the hardware WDT recover from inductive transients produced by brushed DC motors. The extended temperature range tolerates the elevated operating temperatures inside a charger housing that sits behind a high-current rectifier.

Ghi chú thiết kế
The PIC16C622T-04E/SS uses One-Time Programmable (OTP) memory. Once a program is written, the device CANNOT be reprogrammed or code-erased, so a single bit error during development requires scrapping the part. Always build prototypes with PIC16C62x windowed (JW) or PIC16F62x flash parts and migrate to PIC16C622T-04E/SS only after firmware is fully validated. OTP also means field firmware updates are impossible - if your application needs field upgrades, choose PIC16F622 instead.
Place a 0.1 uF decoupling capacitor as close as possible between VDD (pin 20) and VSS (pin 14), with a 10 uF bulk tantalum or ceramic on the same rails. The PIC16C622 is sensitive to supply ripple during EEPROM/OTP programming and to ADC comparator noise during analog acquisition. Keep crystal traces short (<5 mm) and guard-pin the OSC1/OSC2 area with a ground ring to reduce EMI susceptibility from adjacent switching power stages.
The MCLR pin (pin 19) on PIC16C62x is active-low reset and MUST be pulled high through a 10 kohm resistor for normal operation. Do not leave it floating. If in-circuit serial programming (ICSP) is needed, the ICSP connector should sit on MCLR/RB6/RB7/VSS/VDD only and share no other MCU pins. RB6 and RB7 are used as ICSP clock/data and must remain unused in the application or be isolated from external drivers during programming.
The two on-chip analog comparators share their inputs with RA0-RA3 and are not multiplexed to dedicated ADC channels; their offset is +/- 5 mV typical and +/- 25 mV worst-case. For sub-25 mV threshold detection, calibrate the comparator reference in firmware or use an external op-amp. The programmable voltage reference block provides selectable reference steps between 0.31 V and VDD in 7 levels - choose the step that places the comparator threshold above the offset to avoid chatter.
Thông tin tuân thủ
PIC16C62x family predates RoHS adoption. SSOP finish is typically lead-based. AEC-Q100 qualification is not published for this commercial/industrial part; automotive designs should confirm acceptance at the OEM level.
