PIC16LC63AT-04I/SS Übersicht
A PIC16 mid-range microcontroller is a Harvard-architecture RISC device with separate program and data buses, a fixed instruction set of 35 single-word instructions, and a two-stage pipeline that lets most instructions execute in a single instruction cycle (200 ns at 20 MHz / 1 us at 4 MHz). It belongs to the broader 8-bit MCU category (PIC, 8051, AVR), positioned below 16-bit dsPIC/PIC24 and 32-bit MCU families in Microchip's portfolio, and is used wherever deterministic control, low power, and small footprint matter more than raw compute.
Key features include 22 digital I/O pins, two 8-bit timers plus one 16-bit Timer1 with capture/compare, a USART with addressable Receive Interrupt, an SPI/I2C-compatible Synchronous Serial Port (SSP), five analog input channels with 8-bit resolution, and a Watchdog Timer with its own on-chip RC oscillator. Brown-out Reset, Power-on Reset, and an extended 14-bit instruction word complete the integrated peripheral set.
The architecture is fully static CMOS with on-chip oscillator support for crystal, ceramic resonator, and RC modes. The 'LC' designation denotes the low-voltage (3.0-5.5 V) variant, while 'T' marks the Tape & Reel packaging option, '-04' the 4 MHz speed grade, 'I' the industrial -40 C to +85 C temperature range, and 'SS' the 28-pin SSOP outline (0.209 inch / 5.30 mm body width).
Typical applications include industrial control, motor control front-ends, sensor signal conditioning, low-power portable instruments, and consumer appliance user interfaces. Its 5-channel ADC and USART make it a natural fit for serial-connected remote sensor nodes and small protocol bridges in factory and building automation.
When designing with this part, note that the OTP program memory cannot be re-programmed in-circuit; plan firmware revision strategy around a Flash-based sibling such as PIC16F873 if field updates are required. Decouple VDD with a 0.1 uF ceramic close to the pins and follow Microchip's recommended MCLR pull-up and ICSP layout if in-system programming is desired.

Typische Anwendungen
PIC16LC63AT-04I/SS ist geeignet für 6 Anwendungs: Industrial Sensor Interface Module, Low-Power Portable Instrument, Consumer Appliance User Interface, Motor Control Front-End, Building Automation Protocol Bridge, Automotive Body Electronics (Non-Safety).
Industrial Sensor Interface Module
The PIC16LC63AT-04I/SS fits industrial sensor interface designs where deterministic control, 3.3-5 V tolerance, and 5-channel 8-bit ADC suffice. With its 7 KB OTP code space, 192 B RAM, and USART plus SSP, it can host a serial sensor protocol stack and process up to five analog inputs. Compared with a Flash MCU it offers OTP security at lower unit cost in high-volume deployments, but field firmware updates require device replacement; the -40 C to +85 C industrial range covers factory floor environments. Designers should pair it with a 0.1 uF VDD bypass capacitor and follow Microchip's PIC16C63A reference layout for stable A/D readings.
Empfohlen
Low-Power Portable Instrument
For battery-powered portable instruments (handheld meters, simple data loggers, temperature probes) the PIC16LC63AT-04I/SS provides low CMOS quiescent draw, a wide 3.0-5.5 V supply window compatible with single-cell Li-ion or 3 x AA stacks, and a sleep-friendly RISC core. The 4 MHz speed grade (1 us instruction cycle) keeps active current modest while still handling USART-based telemetry. Designers should use the watchdog timer and the LC variant's brown-out reset for unattended battery operation; the 5-channel ADC is sufficient for thermistor, voltage, and current-sense channels typical in portable meters.
Empfohlen
Consumer Appliance User Interface
The PIC16LC63AT-04I/SS is well-suited to consumer appliance user-interface modules: washing-machine control panels, microwave keypads, and dishwasher status displays. Its 22 I/O pins drive 7-segment displays and key matrices directly, while the 5-channel ADC reads potentiometer knobs or thermistor inputs. OTP memory locks firmware at production cost, and the SSOP-28 footprint suits compact appliance PCBAs. The 4 MHz grade keeps EMI low enough to pass typical CE/FCC appliance immunity tests without aggressive filtering, and the LC voltage band handles the 5 V and 3.3 V rails common in modern appliance controllers.
Empfohlen
Motor Control Front-End
The PIC16LC63AT-04I/SS serves in motor control front-ends that pre-process Hall sensors and quadrature encoders before a higher-tier dsPIC takes over closed-loop commutation. Its 16-bit Timer1 with capture input decodes encoder edges, while the 5-channel ADC reads phase currents and bus voltage. The PIC16LC63A's deterministic instruction timing and fast interrupt response suit real-time sensor sampling; designers should migrate to a dsPIC30F device when full sensorless vector control is required. The -40 C to +85 C industrial temperature range covers motor compartment environments.
Empfohlen
Building Automation Protocol Bridge
In building automation, the PIC16LC63AT-04I/SS bridges between sensors on a simple RS-485 link and a higher-tier controller. Its USART with addressable receive interrupt supports 9-bit protocol addressing for multi-drop RS-485 networks, and the SSP peripheral interfaces with sensor front-ends over SPI or I2C. The 5-channel ADC reads local analog sensors (light, occupancy, CO2 reference). With 7 KB of code and 192 B of RAM, the LC63A can host a basic Modbus RTU slave, and its 3.3-5 V tolerance accepts common 24 V-to-5 V building-automation rails via a linear post-regulator.
Empfohlen
Automotive Body Electronics (Non-Safety)
Although not AEC-Q100 qualified, the PIC16LC63AT-04I/SS supports non-safety automotive body modules such as interior lighting, seat-position memory, and accessory controllers when qualified at the module boundary. Its -40 C to +85 C temperature range covers cabin environments, and its 22 I/O pins drive relays, LED strings, and switch inputs directly. The LC voltage band tolerates cranking transients when paired with external TVS protection. Designers targeting safety-critical modules should instead select AEC-Q100 qualified dsPIC30F or PIC18F K-series parts.

Wichtigste Unterscheidungsmerkmale
- Same-die drop-in compatibility with tube-packaged PIC16LC63A-04I/SS (vs. PIC16LC63A-04I/SS)
- Flash alternative available with same pinout and active lifecycle (vs. PIC16F873A-I/SS)
- SSOP-28 outline common across the PIC16LC63A family (vs. PIC16LC63A-04I/SO)
Designhinweise
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 11) and a bulk 10 uF tantalum or aluminum capacitor on the supply rail. The PIC16LC63A's analog supply current and digital supply current share VDD; insufficient decoupling introduces ADC noise and can cause spurious brown-out resets. For battery-powered designs, take advantage of the Sleep mode (current typically < 1 uA) and the watchdog timer to wake the part periodically and maximize battery life.
MCLR (pin 9) must be tied to VDD through a 10 kohm pull-up resistor for normal operation; leaving it floating causes the device to randomly reset. If in-circuit serial programming (ICSP) is required, route RB6/PGC (pin 18) and RB7/PGD (pin 19) to an ICSP header and ensure no low-impedance load on these pins during programming. OTP memory cannot be erased or rewritten - verify firmware with a Flash equivalent (PIC16F873A-I/SS) before committing to OTP production orders.
Estimated: the 28-pin SSOP package has a theta_JA of approximately 95 C/W on a 2-layer 1-oz test PCB, versus 70 C/W on a 4-layer board. At the maximum industrial operating temperature of +85 C, the die junction should remain under +125 C derating limit, leaving roughly 40 C of margin (i.e. ~0.4 W dissipation). The PIC16LC63A's active current at 4 MHz and 5 V is roughly 2 mA, so dissipation stays well under the derating limit; OTP programming draws peak currents up to ~20 mA but should not exceed thermal limits.
The PIC16LC63AT-04I/SS USART supports both synchronous and asynchronous modes; in RS-485 networks configure the 9-bit addressable Receive Interrupt mode to enable multi-drop addressing. For I2C buses, use 4.7 kohm pull-ups on SDA/SCL (pins 24/23) at 100 kHz Standard mode, or 2.2 kohm at 400 kHz Fast mode. The analog inputs AN0-AN4 (pins 1-6) should have source impedances below 10 kohm to settle the internal sample-and-hold within the acquisition window; higher source impedances cause ADC gain errors.
Compliance-Informationen
RoHS compliant per Microchip ordering information (Pb-free finish). Not AEC-Q100 qualified - not recommended for safety-critical automotive applications. Halogen-free per JEDEC JS709B / IEC 61249-2-21.
