PIC16F59-E/PT - 20MHz 8-Bit MCU, 3KB Flash | Microchip
Teilenummer: PIC16F59-E/PT ✓ AktivPIC16F59-E/PT Übersicht
An 8-bit microcontroller is a programmable semiconductor containing a CPU core, program memory, data memory, and peripherals on one integrated circuit. PIC16F59 belongs to the PIC16 family, which is part of the broader embedded-controller and semiconductor hierarchy. Its compact instruction set and modest memory footprint suit applications that need deterministic control, status monitoring, or simple user-interface logic without a high-cost processor.
Key features include 3 KB of Flash program memory, an 8-bit data path, 32 I/O pins, and operation from 2.5 V, 3.3 V, or 5 V according to the verified distributor data. The device also provides a TMR0 timer, a watchdog timer, low-power sleep operation, and in-circuit serial programming. These resources allow a design to combine timing, supervisory behavior, and external control in one integrated device.
The PIC16F59 uses 12-bit program instructions, and most instructions execute within one cycle, while program branches require two cycles according to the family information in the verified search results. Its 33-instruction baseline core and two-level stack keep the programming model straightforward. The 44-lead TQFP provides substantially more I/O capacity than smaller PIC16 packages while remaining compatible with automated board assembly.
Typical applications include industrial control modules, appliance controllers, small sensor-hub boards, LED status panels, and compact embedded systems. The 32 available I/O pins are particularly useful when the design needs digital inputs and outputs beyond the resources of a smaller PIC microcontroller. The PIC16F59-I/PT and PIC16F59T-I/PT variants provide related temperature-grade and packaging options where verified sourcing permits.
Designers should account for programming and clock configuration, provide suitable decoupling near the supply pins, and verify every peripheral signal against the manufacturer pinout before layout release. In-circuit serial programming can simplify production programming, but programming access, oscillator stability, and unused-pin treatment must be checked in the device-specific documentation.
This page combines verified manufacturer and distributor data with package-focused alternatives, explicit data gaps, and practical selection guidance. It adds engineering context for comparing the 44-lead TQFP PIC16F59 variants without treating different-package devices as drop-in replacements.

Typische Anwendungen
PIC16F59-E/PT ist geeignet für 6 Anwendungs: Compact Industrial Control Module, Appliance Controller, LED Status and Sequencer Panel, Small Sensor Hub, Battery-Powered Control Device, Programmable Logic Controller.
Compact Industrial Control Module
PIC16F59-E/PT fits a compact industrial control module because it combines a 20 MHz 8-bit core, 3 KB of Flash, 128 bytes of RAM, and 32 I/O pins in a 44-lead TQFP package. The 32 I/O pins allow discrete sensors, status indicators, relays, and operator inputs to share one controller without an external I/O expander. Its TMR0 timer and watchdog timer support periodic control and supervisory recovery. Before finalizing the layout, verify the exact I/O assignments, oscillator configuration, and E-grade temperature limits against the manufacturer documentation.
Empfohlen
Appliance Controller
The PIC16F59-E/PT is appropriate for an appliance controller when the design needs deterministic low-cost logic rather than a high-performance processor. Its 3 KB Flash accommodates a compact control program, while 32 I/O pins can support buttons, indicators, sensors, and control outputs. The 20 MHz clock provides operational headroom for state-machine control and timing tasks. Because the verified data does not include the detailed timer resolution or output-driver characteristics, the design should verify the relevant electrical limits and use the watchdog timer for recovery from unexpected states.
Empfohlen
LED Status and Sequencer Panel
PIC16F59-E/PT can serve as the controller for a multi-LED status or sequencing panel because its 32 I/O pins provide substantial parallel output capacity. The 3 KB Flash supports stored patterns and control logic, while the 20 MHz 8-bit core can execute finite-state-machine updates efficiently. A designer can use TMR0 for basic timing and the watchdog timer for fault recovery. Validate LED current limits, grounding, switching-noise behavior, and any multiplexed display requirements before assigning the remaining pins because those electrical details are not included in the supplied verified data.
Empfohlen
Small Sensor Hub
The PIC16F59-E/PT offers enough I/O for a small sensor hub that aggregates switches, digital sensors, and local status outputs. Its 128 bytes of RAM is modest, so the application should avoid buffering large datasets and instead process compact state locally. The 20 MHz execution rate supports responsive polling and logic, while sleep mode can reduce consumption between updates. Exact peripheral availability, pin multiplexing, and the operating-temperature limits of the E grade remain to be confirmed from the device-specific manufacturer documentation.
Empfohlen
Battery-Powered Control Device
PIC16F59-E/PT can support a low-duty-cycle control function where the verified 100 nA sleep current is useful between active events. Its 3 KB Flash stores firmware without needing an external memory device, and its 32 I/O pins reduce the need for additional interface components. Wake sources, active current, oscillator startup time, and analog behavior are not quantified in the supplied data, so battery-life calculations must use measured or manufacturer-confirmed values. The watchdog timer can also help recover a device that stalls after a transient fault.
Empfohlen
Programmable Logic Controller
PIC16F59-E/PT is suitable for a small programmable logic controller or fixed-function sequence controller because 32 I/O pins, 3 KB of Flash, TMR0, and a watchdog timer cover many discrete automation tasks. The 20 MHz 8-bit core can implement interlocking logic, operating-state machines, and periodic input sampling in a small board area. For safety-relevant or extended-temperature installations, verify the E-grade limits and consider whether the watchdog and other diagnostics satisfy the required system safety architecture; the supplied data does not establish functional-safety certification.

Wichtigste Unterscheidungsmerkmale
- Verified 44-lead TQFP package with substantial parallel I/O (vs. PIC16F59-I/PT)
- Compact 3 KB Flash controller for cost-sensitive embedded logic (vs. PIC16F59T-I/PT)
- On-chip supervisory and timing resources (vs. PIC16F59-I/PT)
Designhinweise
Place the required supply decoupling capacitors directly beside the PIC16F59-E/PT power and ground pins, using the manufacturer layout and capacitor-selection guidance for the exact operating mode. The verified data confirms 2.5 V, 3.3 V, and 5 V operation but does not specify capacitor values, ESR limits, or maximum supply ramp rates. Those details must be taken from the device datasheet rather than inferred, particularly when the MCU drives relays, LEDs, or other switching loads.
Do not approve a replacement based only on the TQFP dimensions. PIC16F59-I/PT and PIC16F59T-I/PT share the verified 44-pin format, but the ordering-grade suffixes differ and the supplied data does not state their temperature ranges. Check the complete pin names, configuration fuses, programming interface, oscillator configuration, and required qualification for each candidate before releasing a substitute into production.
Reserve access to all in-circuit serial programming signals and keep the programming interface away from high-voltage or noisy switching nodes. Although the PIC16F59-E/PT provides 32 I/O pins, not every I/O function is necessarily available on every package pin. Use the authoritative 44-lead TQFP pin diagram to assign external connections, protect unused inputs according to device guidance, and separate oscillator-sensitive routing from relay or switching-current paths.
Use the watchdog timer as a recoverable supervisory mechanism, but budget for the device's active current, peripheral load, and I/O leakage in addition to the verified 100 nA sleep figure. Estimated battery life should not be calculated from the sleep current alone. Confirm the active current, wake timing, oscillator startup behavior, and brownout thresholds from the manufacturer data or bench measurements before defining the power budget.
Compliance-Informationen
The supplied verified data does not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for the exact ordering code. No compliance status was inferred from the distributor listings.
