PIC16LC620A-04I/SS 概要
An MCU (microcontroller) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral I/O on one die. The PIC16C architecture belongs to the PIC10/12/16 family of RISC microcontrollers, which sits inside the broader 8-bit microcontroller category. 8-bit MCUs continue to dominate cost-sensitive, deterministic, low-power embedded designs - especially where code density and ease of programming outweigh raw throughput. Within that family, OTP (One-Time Programmable) variants such as the PIC16LC620A are intended for volume production where field firmware updates are not required and per-unit programming cost must remain low.
Key features include a 35-instruction RISC core, single-cycle execution except for program branches (200 ns instruction cycle at 20 MHz input clock), a two-level hardware stack, and a programmable watchdog timer. The wide operating voltage range of 2.5V to 6.25V allows direct connection to both 3.3V and 5V rails, while the internal comparator and 8-bit timer modules support mixed-signal designs. Two comparators with programmable reference voltages provide analog signal conditioning without external op-amps.
Typical applications include automotive interior lighting controllers, appliance user-interface panels, simple sensor conditioning, battery-powered instrumentation, and stand-alone logic-replacement boards. The 13 I/O pins easily drive LED arrays, key-scan matrices, and low-speed serial interfaces such as UART or I2C in master mode. The PIC16LC620A-04I/SS (industrial temperature grade -40C to +85C) is suitable for environments where the commercial-grade /04 version cannot operate.
When migrating code, note that the 'LC' suffix denotes the low-voltage CMOS variant and that the 'I' suffix is the industrial temperature grade. For new designs consider flash-based PIC16F equivalents to simplify firmware iteration during prototyping.

主な用途
PIC16LC620A-04I/SS の用途: 7 件s: Automotive Interior Lighting Controller, Home Appliance User-Interface Panel, Battery-Powered Sensor Node, Standalone Logic Replacement Board, Industrial Sensor Signal Conditioning, Smart Card Reader / Access Control, Educational and Hobby Development Boards.
Automotive Interior Lighting Controller
The PIC16LC620A-04I/SS is well-suited to automotive interior lighting controllers where its 13 digital I/O pins can directly drive LED strings via discrete MOSFETs or bipolar transistors. The 2.5 V to 6.25 V supply range accepts a regulated 5 V automotive body rail directly, while the industrial -40 C to +85 C temperature grade covers cabin environments. The two internal comparators implement current-sense feedback for short-circuit protection, and the 96 B RAM holds dimming state across key-cycle events without external EEPROM.
おすすめ
Home Appliance User-Interface Panel
For washing-machine or microwave front-panel controllers, the PIC16LC620A-04I/SS provides enough I/O (13 pins) for a 4x4 key-scan matrix plus 7-segment or LED bar indicators. The 35-instruction RISC core executes state-machine logic in single cycles (1 us at 4 MHz), keeping keypad response below 10 ms. OTP memory protects firmware IP at zero ongoing cost, while the two comparators detect line-voltage zero-cross events without an external op-amp.
おすすめ
Battery-Powered Sensor Node
The PIC16LC620A-04I/SS supports low-power sensor nodes powered from 3.3 V lithium or 5 V USB supplies, with the watchdog timer enabling sleep-mode duty cycling below 1 uA. Its 2.5 V minimum supply voltage extends useful battery life when cells droop under load. The two comparators interface directly to thermocouples or photodiodes for threshold detection, and the 8-bit timer captures pulse-train sensor outputs without CPU overhead.
おすすめ
Standalone Logic Replacement Board
Where designers are migrating 74HC logic gates to a single programmable part, the PIC16LC620A-04I/SS offers 13 I/O, 96 B RAM, and 512 instruction words (896 B OTP) in a compact SSOP-20. The 1 us instruction cycle replaces 10-20 discrete gates in glue logic while adding configurability via firmware. The 35-instruction RISC core is straightforward for logic-replacement C code, and the wide 2.5 V-6.25 V supply removes the need for level translation.
おすすめ
Industrial Sensor Signal Conditioning
The PIC16LC620A-04I/SS conditions analog sensor signals via its two internal comparators with programmable voltage references, outputting clean logic-level triggers to a host PLC or counter. The 2.5 V to 6.25 V supply accepts 5 V industrial rails directly, and the industrial -40 C to +85 C temperature range tolerates factory-floor environments. The 8-bit timer captures pulse widths up to 256 us with hardware start, offloading the CPU.
おすすめ
Smart Card Reader / Access Control
The PIC16LC620A-04I/SS implements low-cost access-control readers where its OTP memory secures proprietary protocol firmware and its industrial temperature grade supports outdoor installations. The two internal comparators interface directly to magnetic-stripe or Wiegand readers, while the 8-bit timer captures bit-stream timing within 1 us accuracy. The 13 I/O pins drive indicator LEDs, buzzer, and relay outputs from a single device.
おすすめ
Educational and Hobby Development Boards
The PIC16LC620A-04I/SS is widely used in educational kits and hobbyist projects where its 35-instruction RISC core teaches fundamentals without overwhelming beginners. Its SSOP-20 footprint is breadboard-friendly with adapter boards, and the wide 2.5 V to 6.25 V supply tolerates both 3.3 V and 5 V USB power sources. The 896 B OTP memory supports complete tutorial projects from blinky LEDs to UART communication, and the industrial temperature grade allows projects to ship in consumer enclosures.

設計ノート
Estimated: at 4 MHz clock, 5 V supply, and 13 I/O pins sourcing 10 mA each into 5 V logic, total device current is approximately 5 mA core + 130 mA I/O = 135 mA, dissipating about 0.675 W in the SSOP-20. The SSOP-20 thermal resistance of 90 C/W (with minimal copper) limits junction temperature to +85 C at ambient +25 C only when I/O current is below 70 mA total. For higher I/O loading, add a ground-pour heat-spreader under the exposed pad or reduce clock frequency.
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 19) and a bulk 10 uF capacitor on the same supply trace. For PIC16C62X designs with external crystal oscillator, keep the crystal and load capacitors within 5 mm of OSC1/OSC2 (pins 8 and 9). Route the MCLR/VPP line (pin 1) directly to the reset circuit - avoid long traces that pick up noise and cause spurious resets during OTP programming.
Do not assume the PIC16LC620A-04I/SS can be programmed in-circuit via standard ICSP - the OTP EPROM requires high-voltage programming (VPP = 13 V typical). Use the Microchip MPLAB PM3 or equivalent production programmer with the appropriate programming adapter. Avoid applying external pull-up to MCLR/VPP without a 10 kohm series resistor, as it can interfere with the high-voltage programming pulse during factory programming.
Estimated: SSOP-20 has a 0.65 mm pin pitch, requiring reflow soldering with a fine-pitch stencil. Reserve 0.4 mm solder-pad width with 0.2 mm gaps to prevent solder bridges between adjacent pins. Keep high-current traces (those carrying I/O loads above 20 mA) at least 2 mm away from the oscillator circuit on the same layer to minimize noise injection into the timing-critical analog blocks.
