PIC16LC58B-04/P Übersicht
An 8-bit PIC microcontroller is a Harvard-architecture RISC processor with separate program and data buses, executed from a fixed instruction set. PIC microcontrollers occupy the hypernym hierarchy 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. They are widely used in cost-sensitive embedded applications due to their small footprint, deterministic instruction timing, and simple development tooling.
Key features of the PIC16LC58B-04/P include 12 I/O pins, a two-level deep hardware stack, direct/indirect/relative addressing modes, seven or eight special-function hardware registers, 12-bit-wide instructions with an 8-bit data path, and 33 single-word instructions. The reduced instruction set executes in a single instruction cycle (except branches which take two cycles), giving an effective throughput of 4 MIPS at 4 MHz.
Typical applications include low-cost consumer appliances, battery-powered remote controls, sensor signal conditioning front-ends, simple LED drivers, and legacy industrial control replacements where pin-compatibility with older PIC16C5X designs is required. The OTP program memory allows single-pass programming for production units, lowering per-unit cost compared to flash variants.
When designing with this device, ensure the MCLR reset pin is pulled high through a 10 kohm resistor and that a proper decoupling capacitor (100 nF) is placed within 5 mm of VDD. Note that OTP parts cannot be reprogrammed - design firmware thoroughly before committing to production volumes.

Typische Anwendungen
PIC16LC58B-04/P ist geeignet für 6 Anwendungs: Battery-Powered Remote Controls, Consumer Appliance Control Boards, LED Lighting Controllers, Sensor Signal Conditioning Front-Ends, Toy and Hobby Electronics, Legacy Industrial Control Replacements.
Battery-Powered Remote Controls
The PIC16LC58B-04/P is well suited to handheld infrared remote controls due to its low-voltage 2.5-6.25 V supply range, which allows operation directly from two or three AA alkaline cells without a boost regulator. Its 12 I/O pins can drive IR LEDs directly through a transistor, while the 33-instruction RISC core executes key-scan and IR protocol encoding with deterministic timing. The 4 MHz clock and 4 MIPS throughput easily handle RC5, NEC, or SIRC protocols in real time. With the SLEEP mode and Watchdog Timer, average quiescent current drops below 10 uA, extending battery life to multiple years. The 3 KB OTP memory holds a full protocol stack plus device-specific code.

Consumer Appliance Control Boards
In cost-sensitive consumer appliances such as washing machines, microwave ovens, and rice cookers, the PIC16LC58B-04/P provides reliable 8-bit control with its 12-bit-wide instruction set delivering compact code density. The 12 I/O pins interface directly to relays, triac drivers, LED indicators, and seven-segment displays. The 3 KB OTP memory holds appliance state machines and user-interface firmware. The industrial-temperature LC variant (PIC16LC58B-04I/P) extends operation to garage and outdoor installations. The 2-level hardware stack is sufficient for simple state-machine firmware without nested interrupts.

LED Lighting Controllers
The PIC16LC58B-04/P can drive multi-channel LED lighting products such as decorative strips, signage, and architectural fixtures. With 12 I/O pins capable of 25 mA sink current, the MCU can directly PWM-drive LED channels without external driver ICs. The 4 MIPS throughput supports software PWM at refresh rates above 100 Hz, eliminating visible flicker. The 2.5-6.25 V supply range accepts power directly from a 3.3 V regulator or 2-3 cell battery pack. The OTP memory prevents firmware tampering, an advantage for commercial lighting installations where field-modification is undesirable.

Sensor Signal Conditioning Front-Ends
Simple sensor signal conditioning applications, such as thermocouple cold-junction compensation, humidity sensor linearization, and analog threshold detectors, can be implemented using the PIC16LC58B-04/P with an external ADC. The 4 MHz clock and 12-bit instruction width allow efficient lookup-table-based linearization routines stored in the 3 KB OTP memory. The 73 bytes of RAM provide scratch space for moving-average filters and calibration constants. The 2-level hardware stack and 33-instruction RISC set ensure deterministic response times, important for safety-critical sensor applications.

Toy and Hobby Electronics
High-volume toy and hobby products benefit from the PIC16LC58B-04/P's combination of low unit cost (approximately $1.86 at qty 1000), compact 18-pin PDIP package, and 3 KB OTP memory. The MCU drives hobby servos, sound chips, and small DC motors through H-bridge drivers using its 12 I/O pins. The 4 MHz clock generates precise servo PWM signals at 50 Hz with 1 us resolution. The OTP memory prevents firmware piracy in competitive toy markets. The wide 2.5-6.25 V supply range accommodates single-cell Li-ion (3.7 V) and 4.5 V battery packs alike.
Empfohlen
Legacy Industrial Control Replacements
Industrial control systems designed in the late 1990s and early 2000s around the PIC16C5X family can be maintained with the PIC16LC58B-04/P as a drop-in replacement, since the OTP-programmed parts in the field must match byte-for-byte to avoid re-certification. The 18-pin PDIP footprint is identical to the original PIC16C58B and PIC16CR58B parts, allowing direct PCB insertion without layout changes. The 2.5-6.25 V supply range accommodates 24 V industrial rails with a simple linear regulator. The 0-70 C commercial temperature range is sufficient for control cabinet environments.

Wichtigste Unterscheidungsmerkmale
- Low-voltage CMOS operation down to 2.5V (vs. PIC16C58B-04/P)
- Industrial temperature range option in identical footprint (vs. PIC16LC58B-04/P)
- Flash reprogrammability for modern designs (vs. PIC16F57-I/P)
Designhinweise
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 14) and a 10 uF bulk capacitor on the same supply rail. The PIC16LC58B-04/P draws typical operating current of 1-2 mA at 4 MHz and 5 V; with SLEEP mode enabled, current drops below 1 uA. Estimated: at 5 V VDD and 4 MHz clock, ICC active is approximately 1.7 mA per Microchip datasheet curves, so the decoupling network must handle this transient current without creating voltage droop above 50 mV.
For the 18-pin PDIP package, route the oscillator traces (OSC1/OSC2, pins 15-16) as short as possible and keep them away from high-current switching traces to avoid clock corruption. If using a crystal oscillator, place the two load capacitors (typically 15-33 pF) symmetrically and as close to the oscillator pins as possible. The MCLR pin (pin 4) must have a 10 kohm pull-up to VDD; do not leave it floating or the part may intermittently reset.
Critical pitfalls when designing with the PIC16LC58B-04/P: (1) OTP memory cannot be rewritten - verify firmware thoroughly before programming; (2) the 2-level hardware stack means deeply nested subroutines will overwrite the return address - keep nesting to 2 levels maximum; (3) the part has NO in-circuit debugger (ICD) interface - use a PIC16F57 or PIC16F1503 for development and prototype verification; (4) ports are NOT 5V-tolerant when VDD is below 5V - level-shift any external 5V signals; (5) brown-out detection is NOT present on the C5X family - design external POR circuitry if needed.
Compliance-Informationen
