PIC16F59-E/P Обзор
A baseline PIC16 microcontroller is an 8-bit RISC processor built around a small instruction set (typically 33 instructions) with a 2-level hardware stack. In the broader taxonomy it sits below mid-range PIC16F1xxx devices in capability but above 6-pin PIC10F parts. Baseline PIC16 devices are commonly used for low-cost, deterministic control tasks where tiny code size and a shallow learning curve matter more than peripheral richness. Flash-based program memory enables field-reprogrammability via ICSP without removing the part from the board.
Key features include a 200 ns instruction execution time, 12-bit-wide instructions, 8-bit-wide data path, low-power 100 nA typical sleep current, and a wide 4.5V to 5.5V supply range. The device has no on-chip data EEPROM, so non-volatile data storage must be implemented with Flash self-write techniques or external storage. Brown-out protection, power-on reset, and watchdog logic are integrated for robust embedded operation.
Typical applications include white-goods and appliance control, simple sensor conditioning, LED drivers, low-cost consumer toys, fan controllers, and remote-control transmitters. Industrial and automotive accessory designs use the extended -40C to +125C variant (E suffix) for cabin and under-hood-tolerant sub-systems. The 40-pin DIP package is also favored for educational, hobby, and breadboard-friendly prototyping due to its large pin pitch and through-hole mounting.
Design consideration: the 2-level hardware stack imposes a strict limit on nested subroutine and interrupt depth - use this device only for flat or shallow call graphs. Designers migrating to PIC16F1xxx mid-range devices gain a deeper stack, more peripherals, and data EEPROM at the cost of higher unit price and slightly more complex peripherals.

Типичное применение
PIC16F59-E/P подходит для 6 применениеs: Appliance Control (Washing Machines, Microwaves), Fan and Pump Speed Controllers, Consumer Remote Control Transmitters, LED Lighting Drivers and Controllers, Industrial Sensor Signal Conditioners, Educational and Hobbyist Microcontroller Learning.
Appliance Control (Washing Machines, Microwaves)
The PIC16F59-E/P is widely used in white-goods and small-appliance control boards where its 3 KB flash, 20 I/O pins, and 20 MHz baseline core handle keypad scanning, LED/buzzer drive, and triac-based load switching. With the E suffix rated -40C to +125C, the part survives the heat of a closed motor-compressor enclosure and the cold of an unheated laundry room. The 100 nA sleep current keeps standby power below 0.5 W, meeting EU eco-design regulations. ICSP enables firmware updates on the production line without removing the part.

Fan and Pump Speed Controllers
The PIC16F59-E/P's 8-bit TMR0 timer and 20 MHz clock generate accurate PWM duty cycles for DC brushless fan or small DC pump control. Its 20 I/O pins support tachometer input, pushbutton setpoint, status LEDs, and an analog reference for closed-loop speed regulation via an external op-amp. The extended -40C to +125C rating suits fan controllers mounted near CPU heatsinks or inside sealed pump housings. Program space accommodates lookup-table-based PI control without external memory.
Рекомендуется
Consumer Remote Control Transmitters
Battery-powered IR/RF remote controls benefit from the PIC16F59-E/P's 100 nA sleep current, 4.5-5.5 V supply (compatible with a single Li-ion cell + LDO), and 3 KB flash for multi-protocol key maps. TMR0 serves as wake-up timer so the part sleeps between button presses. The 40-pin PDIP is favored in low-volume remote designs for hand-soldering and rapid prototyping; high-volume production migrates to the TQFP-44 sibling (PIC16F59-E/PT) sharing the same firmware.
Рекомендуется
LED Lighting Drivers and Controllers
Architectural and decorative LED strips often use a PIC16F59-E/P to drive multiple PWM channels for color mixing, chase patterns, and DMX-512-like protocols. The 20 MHz clock generates smooth 8-bit PWM at refresh rates above 100 Hz to avoid visible flicker. Extended-temperature operation supports enclosed outdoor luminaires. 3 KB flash stores multi-scene programs with non-volatile settings persisted via external I2C EEPROM since the device has no on-chip data EEPROM.
Рекомендуется
Industrial Sensor Signal Conditioners
The PIC16F59-E/P's deterministic 200 ns instruction cycle and 20 MHz clock enable tight sampling loops for digital filtering of slow analog sensor signals (temperature, humidity, 4-20 mA loop). Its 4.5-5.5 V supply is compatible with industrial 24V bus rails after a small linear regulator. The extended temperature rating supports factory-floor enclosures. With 20 I/O, multiple sensors can be multiplexed on one MCU, lowering BOM cost versus discrete logic controllers.
Рекомендуется
Educational and Hobbyist Microcontroller Learning
Universities, technical schools, and Maker communities use the PIC16F59-E/P as a teaching vehicle for assembly and C programming on the baseline PIC16F5X architecture. The 40-pin PDIP fits breadboards with 0.1 inch pitch, the ICSP interface allows in-circuit programming without chip removal, and Microchip's free MPLAB X IDE supports the device natively. Its small 33-instruction set and 2-level stack simplify classroom exercises on interrupts, timers, and I/O while remaining representative of modern 8-bit embedded design.

Заметки по проектированию
The PIC16F59 baseline core has a 2-level hardware stack. Calling a subroutine from within a subroutine that itself handles an interrupt will overwrite the previous return address and crash. Keep the call graph flat or upgrade to a mid-range PIC16F1xxx part if multi-level nesting is required. Always wrap critical sections with banksel-correct register access; the baseline core uses banking that easily corrupts state if forgotten.
Decouple Vdd (pin 19) with a 100 nF ceramic capacitor placed within 5 mm of the pin and a 10 uF bulk capacitor on the same rail. According to the Microchip datasheet, the /MCLR reset pin requires a 10 kohm pull-up to Vdd and a small (around 100 nF) decoupling cap to ground for noise immunity; missing /MCLR decoupling is a common cause of spurious resets near switching loads.
Keep ICSP traces RB6/ICSPCLK and RB7/ICSPDAT short and away from switching load traces to ensure reliable in-circuit programming on the production line. Route the quartz or ceramic resonator within 5 mm of pins OSC1/OSC2 (if external oscillator is used) with a grounded guard trace. Place the 100 nF Vdd cap adjacent to the MCU before any peripheral decoupling caps so the MCU sees the lowest possible impedance at power-up.
Estimated: with 20 I/O pins sourcing or sinking up to 25 mA each, total pin current must remain within the package dissipation budget of approximately 800 mW for the PDIP-40 variant (per Microchip absolute maximum ratings). For LED-matrix or relay-bank loads, use external driver ICs such as ULN2003 or TPIC6B595 to keep per-pin currents within spec and avoid ground-bounce-induced resets.
