PIC16LC558-04/P - 8-bit OTP MCU 3.5KB 4MHz 18-DIP | Microchip
MPN: PIC16LC558-04/P ✗ اختتامِ زندگیPIC16LC558-04/P جائزہ
An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating a CPU, program memory, data RAM, I/O peripherals, and timers on a single die. Within the broader taxonomy, the PIC16LC558 sits in the hierarchy: PIC16C-series OTP MCU -> PIC16 family -> 8-bit PIC microcontroller -> Microchip MCU -> microcontroller -> embedded processor -> semiconductor. The "L" in the prefix denotes a low-power CMOS variant optimized for battery and energy-constrained designs, while the "C" indicates One-Time-Programmable (rather than UV-erasable) EPROM technology.
Key features include a Harvard RISC architecture with a 14-bit instruction word, single-cycle instruction execution except for branches, a 4MHz oscillator input, an 8-bit timer/counter (TMR0), a Watchdog Timer with its own on-chip RC oscillator, Power-on Reset, Brown-out Detection, and In-Circuit Serial Programming™ (ICSP™). The 13 I/O pins support individual direction control, weak pull-ups via OPTION_REG, and direct LED drive capability on PORTA and PORTB. The OTP memory is programmed once via ICSP and cannot be erased, making this part economical for high-volume production where firmware is final.
Typical applications include appliance controls, sensor signal conditioning front-ends, automotive body controllers (non-safety), industrial timers, low-cost remote controls, and small user-interface panels. The 13 I/O pins and 128-byte RAM are sufficient for state-machine-based control loops, simple keypad scanning, and driving multiplexed 7-segment LED or character LCDs without external logic.
When designing with the PIC16LC558-04/P, observe the 4MHz maximum oscillator frequency at 5V (lower at reduced VDD), provide a 100nF decoupling capacitor within 10mm of VDD, and use a bulk 10-100uF capacitor on the supply rail. The 18-pin PDIP footprint is the through-hole industry standard, enabling hand-soldering, breadboard prototyping, and easy firmware rework.

عام استعمالات
PIC16LC558-04/P کے لیے موزوں ہے 6 ایپلیکیشنs: Appliance Control Boards, Industrial Timer and Counter Modules, Remote Control Transmitters, Automotive Body Controllers (Non-Safety), Sensor Signal Conditioning Front-Ends, User Interface Panels with LED/LCD.
Appliance Control Boards
The PIC16LC558-04/P fits appliance control boards because its 13 digital I/O pins are sufficient for keypad scanning, relay/SSR drive, and triac interfacing, while the 4MHz RISC core handles simple state-machine firmware in 3.5KB OTP. Brown-out detection and Power-on Reset protect against supply glitches during motor inrush. Placed as the main controller on the user-interface PCB with 100nF decoupling and a 4MHz crystal on OSC1/OSC2, it provides stable low-cost control without external logic. Compared to flash-based PIC16F alternatives, the OTP version lowers per-unit cost at 50K+ volumes.

Industrial Timer and Counter Modules
The PIC16LC558-04/P fits industrial timer modules because its 8-bit TMR0 with programmable prescaler handles event counting and elapsed-time measurements without external counters. The Watchdog Timer with dedicated RC oscillator resets the MCU on firmware lockup. Placed on a DIN-rail timer PCB with the 18-pin PDIP footprint, it drives LED indicators directly via PORTB and accepts 24V inputs through resistor dividers on PORTA. Brown-out detection ensures clean restart after power dips common in industrial environments.

Remote Control Transmitters
The PIC16LC558-04/P fits IR remote control transmitters because its low-power CMOS 'L' design reduces battery drain and the 13 I/O pins support 4x4 key matrix scanning plus IR LED drive. The 4MHz instruction cycle is fast enough to modulate 38kHz carrier frequencies in software. Placed in a handheld remote with two AAA cells, the Watchdog Timer enables deep sleep via SLEEP instruction to extend battery life. Unlike flash-based alternatives, OTP prevents firmware reverse-engineering of proprietary IR codes.

Automotive Body Controllers (Non-Safety)
The PIC16LC558-04/P fits automotive body control modules for lighting, wiper, and accessory timing because its 13 I/O pins handle relay drive and switch inputs directly. Brown-out Detection protects against load-dump voltage transients when paired with an external TVS. Placed in a sealed under-dash enclosure, the 18-pin PDIP withstands vibration better than surface-mount packages. The PIC16LC558-04I/P industrial-temperature variant extends operation to -40C for under-hood mounting zones.

Sensor Signal Conditioning Front-Ends
The PIC16LC558-04/P fits sensor signal conditioning front-ends because its 8-bit ADC-less design (using comparator + TMR0) measures pulse-width or frequency output sensors like thermistors in RC oscillators. The 13 I/O pins route multiple sensor inputs to a single MCU. Placed between the analog sensor and a higher-level controller, it pre-processes and digitizes signals before UART-style bit-banging transmission. The low-power CMOS design suits battery-powered wireless sensor nodes.

User Interface Panels with LED/LCD
The PIC16LC558-04/P fits small user-interface panels because its PORTB 8-bit bus drives multiplexed 7-segment LEDs or character LCDs directly without external drivers. TMR0 generates LCD refresh or LED multiplexing interrupts at precise intervals. Placed as the sole MCU on a control-panel PCB with the 18-pin PDIP footprint, it scans a 3x4 keypad matrix on PORTA and writes display data to PORTB. The 3.5KB OTP holds table-driven menu logic for typical appliance interfaces.

ڈیزائن نوٹس
Place a 100nF ceramic decoupling capacitor (X7R or X5R) within 10mm of the VDD pin and a bulk 10-100uF electrolytic on the supply rail. The PIC16LC558-04/P can source/sink up to 25mA per I/O pin (200mA total) but the 5V regulator must support the peak load; for relay-driven designs add a flyback diode across each inductive load. The low-power 'L' variant draws approximately 2mA active at 4MHz/5V versus 5mA for the standard 'C' variant, a key advantage in battery designs.
Keep the 4MHz crystal traces short (<10mm) and symmetric, with the load capacitors placed close to OSC1/OSC2. The MCLR pin requires a 10kohm pull-up to VDD and a 100nF capacitor to ground for proper reset; omitting this causes intermittent startup failures. For ICSP programming, route PGD (RB7), PGC (RB6), and MCLR to an in-circuit header or test points to enable field firmware updates before OTP locking.
OTP EPROM cannot be erased - verify firmware on a windowed PIC16C558 UV-erasable emulator before committing code. Brown-out Detect (BOD) and Power-on Reset (POR) must be enabled in the configuration word to prevent code execution at low VDD, which can corrupt EEPROM data and cause latch-up. Do not exceed 4MHz clock at 5V or 1MHz at 3V - the oscillator's internal phase-locked loop fails above these limits.
