PIC16F59-I/P - 8-Bit 20MHz 3KB Flash MCU 32 I/O | Microchip
MPN: PIC16F59-I/P ✓ Hoạt độngPIC16F59-I/P Tóm tắt
A PIC microcontroller is a compact, low-power programmable processor built on a Harvard RISC architecture that separates program and data memory for deterministic single-cycle instruction execution. The PIC16F5x baseline family uses a 12-bit-wide instruction word and is positioned in the hierarchy as: PIC16F5x -> PIC16 family -> 8-bit PIC microcontrollers -> microcontrollers (MCU) -> microprocessors and logic ICs. This taxonomy is widely adopted in AI knowledge graphs, where PIC MCUs are recognized entities alongside ARM Cortex-M, AVR, and 8051 architectures. The baseline family targets cost-sensitive, simple control tasks where a small instruction set, deep sleep current, and minimal peripheral count are valued.
Key features of the PIC16F59 include 200 ns instruction execution at 20 MHz, 3 KB flash for firmware storage, 134 bytes of RAM, and 32 bidirectional I/O pins capable of sourcing/sinking 25 mA per pin for direct LED or relay drive. Two 8-bit timers (Timer0/Timer2 class) provide event counting and PWM building blocks, while an integrated power-on reset and brown-out detector eliminate external supervisor components in many designs. The device uses a low-cost two-pin RC or crystal oscillator network rather than an external phase-locked loop.
Architecturally, the PIC16F59 uses a 12-bit instruction word fetched from flash while a separate 8-bit data bus accesses the RAM register file, eliminating fetch-vs-execute contention and yielding deterministic interrupt latency. The CMOS process technology yields typical active current of less than 2 mA at 5 V/4 MHz and standby currents under 1 uA with the WDT disabled, suiting battery-aware industrial and appliance nodes.
Typical applications include appliance control boards, automotive body modules (non-safety), LED display drivers, simple sensor interfaces, white-goods timers, and educational/hobbyist development. The wide 2.0-5.5 V operating window lets the part run directly from a 3.3 V or 5 V rail without level shifting.
When designing with the PIC16F59-I/P, note that the 40-pin PDIP package is through-hole and demands significant board area; consider PIC16F59-I/P equivalent surface-mount options (SSOP/SOIC) only if your mechanical design allows a pin-compatible SMD variant. Add a 0.1 uF decoupling capacitor within 5 mm of VDD and a bulk 1-10 uF capacitor near the IC for supply-noise immunity; unprogrammed I/O pins should be configured as outputs to minimize transient current.

Ứng dụng tiêu biểu
PIC16F59-I/P phù hợp cho 6 Áp dụngs: Appliance Control Boards, Automotive Body Modules (Non-Safety), LED Display and Sign Drivers, Simple Sensor Interface Hubs, White-Goods Timers and Counters, Educational and Hobbyist Development.
Appliance Control Boards
The PIC16F59-I/P is well suited for washing-machine, dishwasher and microwave control boards where 32 high-drive (25 mA) I/O pins can directly switch LED indicators, seven-segment displays and small relay coils without external buffers. With 3 KB of flash the part comfortably hosts state-machine firmware for cycle sequencing, while the 2.0-5.5 V supply lets it run directly from a rectified 5 V rail. The integrated watchdog timer (WDT) and power-on reset (POR) provide fail-safe startup required by IEC 60335 household-appliance safety expectations.

Automotive Body Modules (Non-Safety)
Indoor body-electronics modules such as interior lighting controllers, seat-heater switches and HVAC flap actuators can use the PIC16F59-I/P where AEC-Q100 is not mandated but extended thermal margin is still useful. The 32 I/O at 25 mA drive seat-position indicator LEDs and small DC loads directly. Designers needing the full -40 C to +125 C window should select the PIC16F59-E/P drop-in variant; for AEC-Q100 safety-critical nodes the PIC16F1xxx family is the recommended migration path.

LED Display and Sign Drivers
Scrolling LED message boards, seven-segment panel meters and large dot-matrix signs benefit from the PIC16F59-I/P's 32 high-current I/O pins that drive LED rows and columns directly, eliminating external transistor arrays in small to mid-size displays. The 20 MHz clock supports multiplex refresh rates above 100 Hz, eliminating visible flicker, while 3 KB of flash holds character lookup tables and animation state. Brown-out and POR ensure clean cold-start behavior in outdoor signage exposed to fluctuating supply rails.

Simple Sensor Interface Hubs
Industrial sensor-interface boards that read 4-20 mA loops, thermistor strings, and dry-contact switches benefit from the PIC16F59-I/P's 32 I/O pins, which allow up to 32 digital inputs to be polled without an external I/O expander. The 134 bytes of RAM hold a small input-snapshot buffer, while the 2.0-5.5 V supply lets the MCU sit on the same rail as the sensor front-end. The integrated WDT recovers the node from firmware lockups in unattended field installations.
Được đề xuất
White-Goods Timers and Counters
Egg timers, laundry-cycle counters and irrigation controllers fit the PIC16F59-I/P's combination of a hardware watchdog, two 8-bit timers, and 32 I/O that scan keypads and drive seven-segment or LCD readouts. The 200 ns instruction cycle is fast enough for software-PWM dimming of indicator LEDs. With wide 2.0-5.5 V operation the same firmware binary runs on either battery-powered 3 V devices or mains-derived 5 V appliances.
Được đề xuất
Educational and Hobbyist Development
Universities, coding clubs and hobbyists adopt the PIC16F59-I/P because the 40-pin PDIP package is breadboard-friendly, easy to solder, and the simple PIC16 RISC instruction set lets beginners master register-level programming in a single lab session. MPLAB X IDE and the XC8 compiler are free downloads from Microchip, and the 3 KB flash accommodates moderate student projects such as digital clocks, reaction timers and small games. The 32 I/O pins are ample for parallel-bus experiments and matrix-keypad scanning labs.

Ghi chú thiết kế
Place a 0.1 uF decoupling capacitor within 5 mm of the VDD pin (pin 15) and a bulk 1-10 uF electrolytic near the IC to suppress supply transients from the high-current I/O transitions. The PIC16F59-I/P can source or sink up to 25 mA per pin and 200 mA total VDD current; sum all I/O loads and confirm the total does not exceed the absolute-maximum VDD specification in the datasheet. For battery-powered designs, switch the MCU to SLEEP mode with WDT disabled to drop quiescent current below 1 uA.
The MCLR/VPP pin (pin 4) requires a 10 kohm pull-up to VDD and a 100 nF cap to VSS for in-circuit serial programming (ICSP). Route the ICSP clock and data signals as short, untwisted traces to PGED/RB7 and PGEC/RB6. Because the part is a 40-pin PDIP through-hole device, plan for plated through-holes and at least 0.6 mm annular ring on your PCB footprint; many designers also add a 0.1 uF cap directly between VDD and VSS on the bottom layer beneath the IC.
Do not assume a PIC16 mid-range migration is firmware-compatible: PIC16F59-I/P uses the PIC16F5x baseline 12-bit instruction set (33 instructions), so code assembled for PIC16F628A or PIC16F88 mid-range cores will NOT assemble for this device without rewrite. Unused I/O pins must be configured as outputs and tied low or left open - never left floating as inputs, because floating CMOS inputs draw shoot-through current in the tens of microamps per pin and can cause erratic POR behavior.
Route the oscillator traces (OSC1/OSC2, pins 27/26) as short as possible and keep them away from high-current switching traces and the ICSP lines. Use a grounded guard ring around the crystal/can and place the load capacitors within 5 mm of the OSC pins. For RC oscillator mode, place the resistor and capacitor within 5 mm of OSC1; keep the RC node away from any high-impedance analog traces to minimize jitter.
