PIC16F1827T-I/SO - 32MHz 8-Bit Flash MCU | Microchip
MPN： PIC16F1827T-I/SO ✓ 啟用中PIC16F1827T-I/SO 概覽
A microcontroller is a programmable integrated circuit that executes embedded control logic from nonvolatile Flash memory. The PIC16F1827 belongs to the PIC16 family of 8-bit RISC microcontrollers and combines a CPU, GPIO, timers, communication peripherals, analog functions, and nanoWatt XLP technology in one device. This product hierarchy places it between general-purpose 8-bit control and larger embedded systems where low power, compact packaging, and deterministic peripheral integration are important.
The verified listing identifies 32 MHz operation, 7 KB Flash organized as 4K by 14 bits, 384 bytes of SRAM, and 12 I/O ports. Microchip describes the family as PIC16 XLP and mTouch capable. These features support compact embedded-control tasks that need programmable digital I/O and low-power operation without requiring a separate external nonvolatile memory device. Detailed RAM organization, ADC characteristics, timer resources, and electrical limits are not present in the supplied result snippets and therefore remain unverified here.
PIC16F1827T-I/SO can serve as the control center for compact consumer products, industrial modules, automotive-oriented embedded subsystems, and low-power sensing equipment. A designer can use its integrated Flash for firmware, GPIO for external devices, and the 32 MHz clock capability for responsive control loops. The 18-pin SOIC footprint is useful when an existing PCB requires through-hole assembly rather than a fine-pitch QFN layout.
For a new design, verify the complete pinout, peripheral availability, oscillator options, electrical limits, programming configuration, and decoupling requirements in the manufacturer datasheet before layout release. The supplied evidence identifies the product as in production and active, but it does not provide a verified unit-price ladder for this exact order code. LCSC shows a starting price of $2.5305 and three units in stock as of the supplied retrieval date; higher quantity prices require a quote or additional distributor confirmation.
This page combines the verified manufacturer status, distributor specifications, commercial availability, and engineering-oriented selection guidance. Its information value is the separation of confirmed facts from missing parameters: designers get a precise fit for PIC16F1827T-I/SO while retaining clear items that must be checked in the full Microchip datasheet before production design.

典型應用
PIC16F1827T-I/SO 適用於 6 應用s: Compact Industrial Control Module, Low-Power Sensor Node, Consumer Control Panel, Capacitive-Touch Interface, Automotive Accessory Controller, Battery-Charging Controller.
Compact Industrial Control Module
PIC16F1827T-I/SO fits compact industrial control modules that need deterministic 8-bit control, 12 I/O, and a 32 MHz clock in an 18-pin SOIC footprint. Its 7 KB Flash stores application firmware, while 384 bytes of SRAM supports working variables and modest protocol or control buffers. The verified -40C to +85C range is appropriate for many factory environments, subject to enclosure temperature and surge requirements. A designer could allocate GPIO to digital inputs, status indicators, relays, and a serial interface, then validate timing against the slowest required actuator. The SOIC package also simplifies inspection and rework compared with a fine-pitch QFN, although its larger footprint is a constraint on very small boards.
推薦
Low-Power Sensor Node
The PIC16F1827T-I/SO is suitable for a small battery-powered sensor node because its PIC16F1827 family is associated with nanoWatt XLP low-power technology. With 12 I/O, engineers can connect sensors and control a power-gated peripheral without routing every signal through a serial bus. The 2.5 V to 5.5 V supply range supports multiple embedded rails, while 7 KB Flash accommodates compact firmware and 384 bytes of RAM handles sampled data. The principal design tradeoff is that exact sleep and active currents are absent from the supplied snippets, so battery sizing must use manufacturer current data and measured firmware behavior rather than infer savings from the XLP label alone.
推薦
Consumer Control Panel
PIC16F1827T-I/SO can serve as the controller in a compact consumer panel containing buttons, LEDs, relays, and a small display interface. Its 12 I/O reduce the need for an I/O expander, and 32 MHz operation provides ample responsiveness for debouncing, indicator updates, and menu logic. The 18-pin SOIC package is maintainable for product-service teams and can be assembled through conventional surface-mount processes. Firmware should keep timing-sensitive behavior interrupt-driven and leave unused pins configured according to Microchip guidance. Because detailed ADC, timer, and pin data are not present in the supplied excerpts, the complete datasheet must be checked before assigning analog functions or relying on a specific peripheral resource.
推薦
Capacitive-Touch Interface
The mTouch identity associated with the PIC16F1827 family makes PIC16F1827T-I/SO a candidate for compact capacitive-touch keypads and sliders. The controller combines programmable logic with Flash firmware, allowing touch scanning, debouncing, and LED-state updates in one device while retaining the same compact 8-bit platform. Layout quality is critical because sensor traces, ground planes, shield electrodes, and analog grounding affect sensitivity. Designers should follow the relevant Microchip touch-controller guidance, preserve clean sensor return paths, and validate against the actual enclosure and human-interface materials. Exact touch-channel count and electrical timing are not established by the supplied search snippets and must be confirmed from the official family datasheet.
推薦
Automotive Accessory Controller
PIC16F1827T-I/SO can evaluate small accessory-controller functions such as switches, lamps, lock logic, or sensor interfaces where an 8-bit CPU and 12 I/O are adequate. The verified -40C to +85C range covers many interior environments, and the 18-pin SOIC package may simplify prototype assembly. However, the supplied data does not establish AEC-Q100 qualification or automotive-grade ordering for this exact suffix, so it must not be treated as production-qualified without manufacturer confirmation. Development work should include transient immunity, load-dump, ESD, brownout, watchdog, and failure-state review. The selected automotive order code and qualification documentation take priority over a superficially similar temperature range.
推薦
Battery-Charging Controller
PIC16F1827T-I/SO can implement a small battery-charging or power-management controller when the design requires programmable state machines, status LEDs, button input, and relay or transistor control. Its 32 MHz class supports responsive control code, while 7 KB Flash and 384 bytes RAM are enough for compact supervisory logic. The 2.5 V to 5.5 V operating range aligns with many low-voltage embedded systems, but charger safety depends on exact analog capabilities, current limits, thermal monitoring, and reference accuracy that are not provided in the supplied excerpts. Prototype only after confirming those functions in the datasheet, then include calibration, fault handling, and worst-case component tolerances in validation.

主要差異化特點
- Exact 18-pin SOIC integration with 32 MHz control (對比PIC16F1827T-I/SO QFN-package variants)
- Substantial code memory in a compact control MCU (對比smaller-memory 8-bit MCUs)
- Low-power family positioning with compact packaging (對比higher-power general-purpose microcontrollers)
- Established active sourcing position (對比unconfirmed or legacy MCU families)
設計說明
Treat the 18-pin SOIC footprint and pin assignment as device-specific rather than copying another PIC16 package mechanically. Place all decoupling capacitance at the device power pins with very short ground returns, route sensitive analog or oscillator inputs away from switching nodes, and follow the exact Microchip layout guidance. The supplied snippets do not contain the pin table or recommended land pattern, so these details must be taken from the current official datasheet before PCB release.
Estimate worst-case supply current from the complete MCU datasheet, external loads, pull resistors, and enabled peripherals before selecting the regulator. Estimated: at a 3.3 V rail, total current demand equals MCU current plus sensor, communications, indicator, and actuator loads; regulator dissipation equals the output voltage times current minus efficiency losses. Because active, sleep, and peripheral currents are not included in the verified snippets, do not substitute assumed current values into production power sizing.
Do not infer a drop-in replacement from a similar PIC16 family name. A valid substitution must preserve the 18-pin SOIC footprint, exact I/O and power pins, 2.5 V to 5.5 V electrical limits, memory availability, peripheral multiplexing, oscillator behavior, and programming requirements. The supplied search results do not verify distinct pin-compatible substitutes, so reuse existing firmware and PCB only after a complete pin-by-pin and timing review plus bench validation.
For a low-power or capacitive-touch implementation, minimize leakage around sensor traces and preserve the ground reference recommended by Microchip. Keep oscillator components and sensitive analog nodes compact, keep high-current return paths away from precision inputs, and test the assembled board in its final enclosure. These layout measures matter because the product's family-level XLP and mTouch positioning does not guarantee low-power or touch performance if external leakage, grounding, or enclosure coupling is poor.
合規資訊
The supplied search results do not explicitly provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification claims for the exact order code. Compliance fields are therefore unknown rather than inferred.
