PIC16F57-I/SP - 20MHz 8-Bit Flash MCU | Microchip
MPN: PIC16F57-I/SP ✓ Hoạt độngPIC16F57-I/SP Tóm tắt
A PIC microcontroller is an embedded processor that combines a compact CPU core, program memory, data memory, and peripherals in one integrated circuit. PIC16 devices form the entry level of the PICmicro family, using a RISC-oriented instruction set and a compact architecture suited to control logic, timers, digital I/O, and small state machines. Microchip describes the PIC16F57 as a FLASH-based member of this family, allowing firmware updates without removing the device from its target circuit.
The supplied data identifies a maximum clock frequency of 20 MHz, a 200 ns instruction execution time, and a 33-single-word instruction set. Its 3 KB FLASH program memory is specified as 2K x 12, while Mouser lists 72 bytes of RAM and 20 I/O-related information. These attributes make the PIC16F57-I/SP suitable for compact embedded controllers where program memory, pin count, and simple firmware execution are more important than high peripheral integration or large data storage.
The part is identified by the I/SP ordering suffix in distributor results, with the verified listing specifying a 28-SPDIP package. The target’s supply and exact electrical limits are not consistently available in the supplied snippets, so any absent technical parameter is marked for verification rather than inferred. A lifecycle result identifies the family as active, but production status and stock should be confirmed with the manufacturer or an authorized distributor before procurement.
Typical use cases include small appliance controllers, industrial automation modules, automotive accessory logic, consumer products, and general-purpose embedded control boards. The 20 MHz operating speed and 8-bit architecture suit periodic sampling, relay or indicator control, key scanning, and simple communication or timing routines. The 28-pin SPDIP package is particularly convenient for prototyping, automated assembly, and educational or legacy designs that already use through-hole footprints.
For PCB design, verify the exact pin assignments from the manufacturer datasheet before assigning signals or power. The MCU requires correct oscillator, reset, programming, decoupling, and I/O routing even though the supplied search results do not provide a complete pin table or application circuit. Firmware should use the PIC16F57 memory and peripheral definitions appropriate to the exact device variant, and production designs should account for the available 3 KB program memory and 72 bytes of RAM.
This page consolidates the verified manufacturer and distributor descriptions, package information, identified alternatives, and practical selection context for engineers comparing PIC16F57 variants. It is intended to make the 20 MHz 8-bit MCU decision faster while preserving uncertainty where the supplied sources do not establish a complete electrical specification.

Ứng dụng tiêu biểu
PIC16F57-I/SP phù hợp cho 6 Áp dụngs: Small Appliance Controller, Industrial Automation Module, Automotive Accessory Logic, Consumer Embedded Product, Educational and Prototype Controller, Timing and Discrete Control Board.
Small Appliance Controller
PIC16F57-I/SP fits compact appliance control because its 20 MHz 8-bit PIC16 RISC core can execute control logic quickly while using 3 KB of FLASH program memory and 72 bytes of RAM. It can manage button inputs, indicators, timers, relays, or simple motor-control sequencing without requiring a high-end processor. The 28-SPDIP package is useful for through-hole prototypes and production assemblies that favor easy inspection and rework. The main design check is whether the selected firmware, I/O count, and timing requirements fit the available memory and device pin budget.
Được đề xuất
Industrial Automation Module
PIC16F57-I/SP is appropriate for entry-level industrial automation functions where a deterministic 8-bit controller must handle discrete I/O, timing, and simple state machines. Its 20 MHz clock and 200 ns instruction execution provide useful headroom for periodic tasks, while FLASH permits firmware updates during development. The MCU does not provide a verified high-speed communication or analog-performance claim in the supplied data, so engineers should confirm peripherals and electrical limits before assigning bus, safety, or precision-control duties.
Được đề xuất
Automotive Accessory Logic
PIC16F57-I/SP can be evaluated for non-safety automotive accessory logic because Microchip describes the PIC16F57 family as adaptable for automotive applications. The 20 MHz 8-bit core and FLASH memory suit relay sequencing, indicator control, switch debouncing, and basic vehicle accessory functions. However, the supplied sources do not verify AEC-Q100 qualification, automotive temperature range, transient protection, or functional-safety suitability. Those items must be confirmed in the full datasheet and system qualification before production use.
Được đề xuất
Consumer Embedded Product
PIC16F57-I/SP suits entry-level consumer products that need reliable local control rather than extensive connectivity. Typical tasks include key scanning, display or indicator sequencing, timeout management, motor or relay control, and compact firmware-driven user interfaces. Its 3 KB FLASH and 72 bytes of RAM impose a clear firmware budget, but the 20 MHz clock provides sufficient timing margin for many control loops. The 28-SPDIP package simplifies educational prototypes and through-hole assemblies, although surface-mount products may prefer a smaller package variant.
Được đề xuất
Educational and Prototype Controller
PIC16F57-I/SP is well suited to learning, prototyping, and small proof-of-concept boards because it combines a simple 33-instruction PIC16 architecture with FLASH program memory and a conventional 28-SPDIP package. Students or engineers can use the MCU to demonstrate timers, digital I/O, interrupts, memory organization, and embedded state-machine design without adopting a complex high-performance MCU. Through-hole assembly also makes breadboard and manually inspected prototype construction practical. Firmware should still be tested against the exact device ID and programming configuration before deployment.
Được đề xuất
Timing and Discrete Control Board
PIC16F57-I/SP can serve as the central controller in a timing or discrete-control board that coordinates switches, lamps, relays, and sequencing logic. The 20 MHz clock allows software timing resolution beyond a slow human-interface application, while the 72-byte RAM is appropriate for modest state variables and the 3 KB FLASH space supports a compact control program. Because the verified snippets do not enumerate timer widths, interrupt sources, or I/O pin assignments, the complete datasheet should guide the implementation and validate timing-critical behavior.

Ghi chú thiết kế
The verified package is 28-SPDIP, so use a through-hole footprint with the correct row spacing, drill size, pin-1 marking, and mechanical clearance specified by Microchip. Do not substitute the PIC16F57-I/SO surface-mount option without changing the PCB footprint. Before layout release, verify every oscillator, programming, reset, supply, and I/O connection against the complete manufacturer pinout because the supplied search results do not provide the full numbered pin table.
Decouple the MCU supply close to the device pins with the capacitance and placement required by the manufacturer datasheet. The supplied data does not establish the operating voltage range, current consumption, or absolute maximum limits, so do not infer a supply value from the PIC16F57 family name. Confirm startup, brownout, oscillator, programming, and I/O voltage behavior before applying power; any estimated power figure should be calculated from verified operating conditions.
Keep oscillator and sensitive timing traces short and route programming signals away from noisy switching nodes. The 20 MHz clock can make short return paths and clean grounding important even though the target is an 8-bit MCU rather than a high-speed communications processor. For designs using external relays, motors, lamps, or long wires, separate noisy power paths from the controller ground and use appropriate protection; those protection requirements are not specified in the verified snippets.
Thông tin tuân thủ
The verified search results do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. The lifecycle result states ACTIVE, but current inventory and qualification should be confirmed directly with Microchip or an authorized distributor.
