PIC16C58B-04/SO - 4MHz 8-Bit OTP MCU, 3KB | Microchip
MPN: PIC16C58B-04/SO ✗ اختتامِ زندگیPIC16C58B-04/SO جائزہ
A PIC16C5X microcontroller is a member of the 8-bit microcontroller family that uses a RISC architecture with only 33 single-word, single-cycle instructions, providing 2:1 code compression over other 8-bit microcontrollers in its class. All instructions execute in a single instruction cycle (200 ns at 20 MHz) except for program branches which take two cycles, enabling predictable deterministic control. The architecture includes seven or eight special-function hardware registers, direct/indirect/relative addressing modes, and a watchdog timer for reliable unattended operation.
Key features include the 4 MHz oscillator (the -04 speed grade), brown-out detection support, an 8-bit real-time clock/counter (TMR0) with 8-bit prescaler, power-on reset, and an operating voltage range of 2.5 V to 5.5 V. The OTP (one-time-programmable) program memory allows factory or field programming using a standard device programmer, while the SOIC-18 package supports hand-solderable surface-mount assembly. The wide VDD range and CMOS design also deliver extremely low power consumption, with typical supply current under 2 mA at 5 V/4 MHz and standby current in the microamp range.
The device uses a Harvard architecture with separate code and data buses, a 12-bit wide instruction word, and an 8-bit wide data path. The 12 I/O pins are bidirectional with individually programmable direction registers, and several pins can be configured for alternate functions such as TMR0 clock input, interrupt, or device reset. This architecture is field-proven in millions of low-cost embedded products and is supported by a mature toolchain including MPLAB IDE, MPASM assembler, and ICD/debug tools.
Typical applications include consumer appliance controls, simple sensor interfaces, LED driver controllers, battery chargers, automotive body electronics, industrial timers and counters, and low-cost replacement of discrete logic. The 4 MHz speed grade is well-suited to sub-1 MIPS control tasks where deterministic response and minimal BOM cost matter more than raw throughput.
When designing with this device, the OTP memory must be programmed before final assembly using a compatible device programmer such as MPLAB PM3 or PICSTART Plus. Because OTP parts cannot be reprogrammed in-circuit, firmware validation should be performed on a JW or windowed version during development. The wide operating voltage (2.5 V to 5.5 V) allows direct connection to both 3.3 V and 5 V systems without level shifters.

عام استعمالات
PIC16C58B-04/SO کے لیے موزوں ہے 6 ایپلیکیشنs: Consumer Appliance Control, LED Driver and Lighting Controller, Battery Charger and Power Management, Automotive Body Electronics, Industrial Timer and Counter, Low-Cost Replacement of Discrete Logic.
Consumer Appliance Control
The PIC16C58B-04/SO fits consumer appliance control boards (coffee makers, toasters, washing machines) because its 3 KB OTP memory, 12 I/O pins, and 4 MHz RISC core deliver enough processing power for keypad scanning, LED driving, and simple state-machine logic. The 2.5 V to 5.5 V operating range allows direct connection to 3.3 V or 5 V sensor and triac driver rails without level shifters. With a 250 ns instruction cycle, the MCU can debounce mechanical switches and drive 7-segment displays in real time while leaving headroom for a small user-interface routine. The wide operating voltage and CMOS design also keep standby current low, important for Energy Star-rated appliances.

LED Driver and Lighting Controller
The PIC16C58B-04/SO can drive multi-channel LED arrays in decorative lighting, signage, and architectural fixtures because its 12 I/O pins are sufficient to PWM-control 8-10 LED channels with software bit-banging at 4 MHz. The 8-bit TMR0 with 8-bit prescaler can generate the timebase for software PWM dimming and color-mixing routines. The 2.5 V minimum VDD allows direct operation from a single-cell Li-ion or two-AA battery pack, enabling battery-powered portable lighting products. The OTP memory locks the firmware to prevent field tampering with brightness curves or color-mixing profiles.

Battery Charger and Power Management
The PIC16C58B-04/SO serves as the supervisory controller in single-cell NiMH or Li-ion charger designs where it monitors battery voltage through an ADC-less comparator scheme using a digital I/O pin and reference. Its low standby current (microamp range) and 2.5 V to 5.5 V VDD make it well-suited to always-on battery management circuits. The 4 MHz speed is sufficient to implement CC/CV charge profiles, temperature monitoring, and safety timer logic in firmware. The OTP memory ensures the charge profile cannot be corrupted in the field, a regulatory requirement for many consumer battery products.

Automotive Body Electronics
The PIC16C58B-04/SO is used in low-end automotive body modules (interior lighting controllers, seat-position sensors, simple HVAC actuators) where its automotive-qualified -04I extended temperature grade handles -40C to +85C under-hood and cabin environments. The 4 MHz CPU is fast enough for LIN-bus software emulation or simple switch-matrix scanning at automotive switch-bounce rates. The 12 I/O pins can directly drive automotive relays, LEDs, and small solenoids through Darlington buffers. The OTP memory locks the calibration data and OEM firmware, preventing unauthorized field modifications of safety-relevant control logic.

Industrial Timer and Counter
The PIC16C58B-04/SO is well-suited to industrial timer, counter, and pulse-generator applications (conveyor-belt controllers, batch counters, machine run-time accumulators) where its 8-bit TMR0 with 8-bit prescaler provides accurate timebase generation and the 12 I/O pins can interface to 24 V industrial signals through optocouplers. The 4 MHz instruction rate is sufficient to debounce noisy mechanical inputs and count pulses at rates up to several kHz. The integrated watchdog timer and brown-out reset are essential for unattended industrial installations where firmware hangs or power glitches must trigger automatic recovery.

Low-Cost Replacement of Discrete Logic
The PIC16C58B-04/SO can replace dozens of 74-series logic gates in glue-logic consolidation, providing configurable I/O, timing, and state-machine behavior in a single SOIC-18 package. The 4 MHz CPU and 33-instruction RISC set are sufficient to implement custom encoders, decoders, sequence detectors, and protocol converters in firmware, replacing entire boards of discrete CMOS logic. The 2.5 V to 5.5 V VDD range and CMOS inputs are directly compatible with 74HC/74HCT logic signal levels. The OTP memory locks the logic function at programming time, eliminating the need for in-system firmware updates in the final product.

ڈیزائن نوٹس
The PIC16C58B uses OTP (one-time-programmable) memory and cannot be erased or reprogrammed in-circuit. Validate firmware on a JW (windowed) PIC16C58B or on the flash-based PIC16F57 development board before committing to OTP production parts. A single code bug locked into OTP memory results in scrapped inventory. Use a socketed programmer such as MPLAB PM3 or PICSTART Plus to allow easy re-programming during prototyping.
The PIC16C58B has a wide 2.5 V to 5.5 V operating voltage but does not include an internal voltage regulator; the VDD pin must be bypassed with a 100 nF ceramic capacitor placed within 5 mm of the package, plus a 10 uF bulk capacitor if VDD is supplied from a long trace or remote LDO. Brown-out reset and power-on reset are enabled by configuration bits and should be left enabled for reliable startup in noisy industrial environments. Watchdog timer (WDT) should also be enabled with a typical 18 ms timeout to recover from firmware hangs.
The /MCLR pin (pin 4) must be pulled up to VDD through a 10 kohm resistor for normal operation, and a 100 nF capacitor from /MCLR to VSS provides hardware reset debouncing. The OSC1/OSC2 pins (16/15) can drive a 4 MHz crystal with two 22 pF load capacitors, or accept an external CMOS clock signal on OSC1 with OSC2 left open. Place the crystal within 5 mm of the MCU and keep OSC traces short to minimize EMI. Unused I/O pins should be configured as outputs (low) to minimize current draw, never left floating.
The 18-SOIC package has 1.27 mm (50 mil) pin pitch, requiring 8-mil traces and 8-mil spaces for escape routing. The exposed pad (thermal pad) on the bottom is not present on the SOIC-18 PIC16C58B but is present on DFN/QFN variants - confirm the package code from the part marking before laying out the footprint. For high-noise industrial environments, route the OSC1/OSC2 traces over a continuous ground plane and place a guard ring of ground vias around the crystal to prevent capacitive coupling from switching signals.
