PIC16LC64A-04/L 개요
A PIC microcontroller is a family of 8-bit RISC microcontrollers built around the Harvard architecture, where program and data memories are physically separate. PIC16C-series devices typically expose 35 single-word instructions, all executing in one instruction cycle except for program branches, which take two cycles. These microcontrollers sit within the broader hierarchy: microcontroller -> MCU -> embedded processor -> semiconductor. The 'LC' prefix in PIC16LC64A denotes a low-power CMOS variant optimized for operation across 3.0 V to 5.5 V, extending battery-backed and portable use cases.
Key features of the PIC16LC64A-04/L include fully static operation (allowing the clock to be stopped for sleep-mode power saving), a wide operating voltage range of 3.0 V to 5.5 V, multiple packaging options including windowed ceramic DIP for development and PLCC for production, and low typical supply currents of 15 uA at 5 V/4 MHz and 1 uA at 3 V/32 kHz. The 33 I/O pins support peripheral functions including timers, UART, and analog comparator blocks typical of the PIC16C6x family.
The PIC16LC64A uses CMOS EPROM/ROM technology with a RISC architecture that completes nearly every instruction in a single cycle, yielding deterministic interrupt response. Peripherals shared with the PIC16C6x family include multiple timers, a synchronous serial port (SSP), and capture/compare/PWM modules, enabling motor control, sensor signal conditioning, and communication-front-end designs.
Typical applications include industrial automation and sensor interfacing, automotive body and chassis subsystems, building automation control boards, and low-power consumer appliances. Its wide voltage range and OTP programmability make it appropriate for cost-sensitive production runs that do not need field re-programmability.
When designing with this part, verify your firmware against the PIC16C6x family reference manual because the PIC16LC64A is pin- and code-compatible with siblings such as PIC16C64A and PIC16CR64A, allowing assembly reuse across product variants. Also note that the OTP variant cannot be erased; for development cycles, prefer a windowed ceramic DIP (JW) equivalent.

일반적인 애플리케이션
PIC16LC64A-04/L 적합 용도: 6 애플리케이션s: Industrial Automation Control, Automotive Body Electronics, Building Automation & HVAC, Low-Power Sensor Hubs, Consumer Appliance Control, Communication Front-End & Modem Glue.
Industrial Automation Control
The PIC16LC64A-04/L suits industrial control boards where 33 I/O lines can drive relays, opto-isolators, and sensor front-ends in 24 V-sourced chassis. Its 3.0-5.5 V supply tolerance lets it ride through noisy DC rails without complex regulation, while the 128-byte RAM and 3.5 KB OTP cover typical ladder-replacement logic for pumps, conveyors, and HVAC dampers. The fully static core lets the clock stop in standby, dropping system current to single-digit microamps during idle periods. Engineers should add an external watchdog timer and bulk decoupling per Microchip's PIC16C6x hardware design checklist for factory-floor reliability.
추천
Automotive Body Electronics
The PIC16LC64A-04/L operates across -40C to +85C and integrates 33 I/O pins, which map directly to body-control tasks such as mirror adjustment, lighting drivers, and seat-memory switches. Its 4 MHz core and 15 uA active current keep quiescent drain low in always-on automotive networks, and the PLCC-44 package supports selective solder-through-hole reflow profiles used in under-dash modules. The 3.5 KB OTP code space accommodates typical BCM subroutines with room for diagnostic routines. AEC-Q100 qualification should be confirmed at the variant level before production release in passenger-vehicle subsystems.
추천
Building Automation & HVAC
Building-automation controllers use the PIC16LC64A-04/L to handle multiple sensor inputs (temperature, humidity, occupancy) and actuator outputs (fans, dampers, valves) within a single 44-pin package. The wide 3.0-5.5 V supply range is convenient for 24 VAC-derived DC rails, and the OTP program memory prevents inadvertent firmware erasure during field service. With 35 single-word instructions, the 4 MHz core executes control loops in well under a millisecond, supporting PID loops for zone temperature regulation. The PIC16C6x timer and capture peripherals simplify zero-cross detection for triac-driven AC loads.
추천
Low-Power Sensor Hubs
Battery-powered sensor hubs benefit from the PIC16LC64A-04/L's static CMOS design, which lets the system clock be gated to sub-1 uA standby. The PIC16C6x timers can wake the core from sleep on a GPIO change or overflow, enabling duty-cycled sensing schedules that extend battery life into the multi-year range. The 33 I/O lines accommodate multi-channel ADC scanning via external ADC plus on-chip comparators. Production OTP programming locks firmware against tampering, suitable for metering deployments where field upgrade risk outweighs the benefit of Flash flexibility.
추천
Consumer Appliance Control
White-goods controllers in washing machines, dishwashers, and microwave ovens leverage the PIC16LC64A-04/L's 33 I/O to drive seven-segment displays, keypads, and motor-control triacs from a single MCU. The 3.5 KB OTP fits typical appliance state machines plus diagnostic subroutines for service mode. Industrial temperature ratings and a wide supply range tolerate the warm enclosures of kitchen equipment and the noise of universal-motor PWM. Designers appreciate the compatibility of the LC64A pinout with PIC16F74 prototypes that accelerate firmware bring-up.
추천
Communication Front-End & Modem Glue
For legacy serial-communication front ends (RS-232/RS-485 protocol converters, modem glue logic, simple protocol bridges), the PIC16LC64A-04/L provides ample UART modules and interrupt flexibility to handle framing, retransmission, and watchdog duties. The 4 MHz clock is adequate for bit-banged half-duplex protocols at common 9.6 to 115.2 kbaud rates. The wide supply range lets the device share 3.3 V or 5 V rails with mixed-logic PHYs without level shifters. OTP code ensures design IP is not easily extracted from deployed units, an advantage for industrial gateways.

주요 차별점
- OTP EPROM with 3.5 KB code space (vs PIC16C64A-04/L)
- Wide 3.0-5.5 V supply including low-power CMOS (vs PIC16C64A-04/L)
- Single-supply 33 I/O with broad peripheral set (vs PIC16LC65A-04I/L)
설계 노트
Place a 100 nF decoupling capacitor within 5 mm of the Vdd pin (pin 20) and a bulk 10 uF aluminum-polymer capacitor on the supply rail. The PIC16LC64A-04/L draws 15 uA typical at 5 V/4 MHz active per Microchip family data; Vdd droop during high-I/O switching can cause spurious resets if bulk capacitance is undersized. Consider a low-Iq LDO such as MCP1702 for battery applications where the input rail is shared with RF or motor loads.
Because the PIC16LC64A-04/L uses OTP EPROM, in-system firmware upgrades are impossible once the device is programmed. Reserve a sufficient code margin (target ~70 percent of 3.5 KB) and code-protect unused areas. For field-serviceable designs, prototype with the Flash-based PIC16F74-I/L in the same PLCC-44 footprint and only transition to OTP after firmware freeze. Always confirm MCLR pull-up resistor value (typically 10 kOhm) to prevent leakage-induced resets in low-power circuits.
Route the oscillator traces (OSC1 pin 9, OSC2 pin 10) as short, symmetric traces and guard them from switching signals. Use a four-layer stack-up with a continuous ground plane beneath the PLCC-44 footprint to reduce EMI susceptibility on the 33 I/O pins. Keep ICSP pins RB6 (pin 27) and RB7 (pin 28) accessible on the PCB edge or test pads; otherwise, in-circuit programming during manufacturing becomes difficult, forcing socketed programming which adds cost.
