PIC10F204-I/P - 8-Bit 4 MHz Flash Microcontroller | Microchip
MPN： PIC10F204-I/P ✓ 啟用中PIC10F204-I/P 概覽
An 8-bit microcontroller is a programmable semiconductor that executes firmware and manages digital inputs, outputs, timers, and other peripherals. PIC10F204-I/P belongs to the Microchip PIC10F family, which sits within the broader hierarchy of embedded microcontroller, embedded processor, and semiconductor product categories. Its fully static operation permits the processor to remain in a stable low-activity state when clocking is stopped, depending on the device configuration.
Verified distributor information identifies 384 bytes of Flash organized as 256 words by 12 bits and four general-purpose I/O lines. The manufacturer describes a compact RISC instruction set with 33 instructions, reducing code-density and learning complexity for basic control products. At the stated 4 MHz operating point, the architecture supports straightforward timing for indicators, simple user interfaces, relay logic, sensing, and low-speed control loops.
The exact operating voltage, memory-map details, oscillator options, reset behavior, I/O electrical limits, and peripheral configuration are not present in the supplied snippets. Those values are therefore marked as data needed rather than inferred. Designers should use the official Microchip documentation for those details before setting operating limits, compiling firmware, or laying out the PCB.
PIC10F204-I/P is appropriate for basic embedded controllers, small sensor interfaces, LED status systems, compact automation controls, and low-power products where a small Flash MCU and through-hole package simplify prototypes or servicing. Through-hole DIP construction also supports educational breadboards and manually assembled control boards. A switching supply, crystal, or larger external circuit is not justified solely from the supplied 4 MHz figure; actual peripheral and clock requirements must be checked in the complete datasheet.
For firmware development, use a programmer and toolchain supported by the selected PIC10F device family. Keep firmware within the verified 384-byte Flash limit and account for bootloader, configuration-word, and application-state requirements. Because only four I/O pins are listed, confirm that the intended interface, programming connector, indicator LEDs, and external controls fit the available pins.
This page consolidates manufacturer architecture details, distributor identification, sourcing links, and design-oriented guidance. It distinguishes verified facts from missing electrical data, helping engineers evaluate PIC10F204-I/P for low-complexity embedded designs without assuming unverified specifications.

典型應用
PIC10F204-I/P 適用於 6 應用s: Basic Sequential Control, LED Status Panel, Compact Sensor Interface, Educational Control Board, Low-Power Timer Module, Appliance User Interface.
Basic Sequential Control
PIC10F204-I/P fits a compact controller that sequences lamps, indicators, or discrete outputs according to a short program. Its verified 384-byte Flash capacity is appropriate for small state machines, while most of the 33 RISC instructions execute in one 1 µs cycle at 4 MHz; branches take two cycles. The design must remain within four verified I/O pins, so confirm output count and active levels against the official pinout. A simple reset, programming interface, output-driver stage, and decoupling network can support a low-power control board without an unnecessary larger MCU.
推薦
LED Status Panel
The four I/O lines and 384 bytes of Flash make PIC10F204-I/P a practical controller for a small LED status panel driven by a short state machine. Its 8-bit RISC core and 4 MHz operation provide deterministic timing without requiring a higher-performance processor. Use suitable current-limiting resistors and verify each LED's forward current against the official I/O limits. The final pin assignment must reserve the pins required by programming or power, and any timer-based blinking behavior should be validated against the complete timing specification.
推薦
Compact Sensor Interface
PIC10F204-I/P can supervise a low-pin-count sensor node when the sensor interface is simple and the program fits within 384 bytes. The four verified I/O pins support basic digital signaling, while the 4 MHz core provides predictable instruction timing. Before selection, confirm whether the target requires an ADC, comparator, timer capture, or another peripheral not documented in the supplied excerpts. Interface voltage levels, sensor supply current, and I/O drive limits must also be checked in the official data sheet before the PCB is finalized.
推薦
Educational Control Board
The 8-pin PDIP package makes PIC10F204-I/P approachable for breadboard prototypes, teaching kits, and manually assembled embedded-control demonstrations. Learners can experiment with the 33-instruction RISC architecture while observing the difference between one-cycle instructions and two-cycle program branches at 4 MHz. The package is convenient for socketed or through-hole construction, but actual pin functions and programming connections must be taken from the official pinout. Include a regulated supply and suitable protection so experiments cannot damage the MCU.
推薦
Low-Power Timer Module
PIC10F204-I/P is suitable for a small timing module whose behavior can be represented with a few timers, state flags, and output transitions. The fully static CMOS architecture and 4 MHz RISC operation support predictable low-complexity control, but the supplied data does not identify timer channels or sleep-current values. Engineers must confirm those specifications in the official documentation, measure worst-case timing, and account for oscillator startup if the design uses a low-power clocking arrangement.
推薦
Appliance User Interface
PIC10F204-I/P can manage a minimal appliance user interface containing a few pushbuttons, status LEDs, and a simple output. Its four I/O pins and 384-byte Flash footprint are useful when the interface is deliberately small, while the PDIP package simplifies repair-oriented through-hole assembly. Confirm debounce, indicator loading, and output functions within the verified pin budget. If the appliance requires a display, buzzer, relay driver, safety monitoring, or more interfaces, move to a larger MCU or add discrete interface circuitry.

選型指南
Do not choose it merely because it is inexpensive. First confirm the required supply voltage, timer and interrupt requirements, analog functions, oscillator arrangement, programming interface, and I/O electrical limits in the official documentation. A larger 8-bit or 32-bit MCU is preferable when firmware, I/O, communications, or mixed-signal requirements exceed what the four verified pins and memory can support. No qualified drop-in substitute was established by the provided cross-reference results, so source risk should be managed through authorized distributors rather than an unverified pin-compatible substitute.

設計說明
Do not treat related PIC10F part numbers as drop-in substitutes without comparing the official pinout, configuration words, memory map, peripheral set, voltage range, and programming interface. The verified cross-reference search mentions PIC10F202-I/P and PIC10F206-I/P as related devices, but it supplies no quantitative compatibility evidence. Use a blank-chip redesign and full firmware review rather than assuming that firmware written for PIC10F204-I/P will execute correctly.
Confirm the supported supply-voltage range, current limits, and decoupling requirements in the official Microchip documentation before laying out the power circuit. The supplied snippets verify an industrial temperature range of -40 °C to +85 °C but do not provide operating or absolute-maximum voltage values. Place the required supply bypass capacitor close to the device pins and ensure the selected source remains within all verified electrical limits over temperature.
Reserve programming access during PCB layout even if only four I/O pins are available. The exact programming pins, power pins, and direction of each I/O were not supplied, so use the official package drawing rather than inferred assignments. For a hand-assembled or repair-oriented product, the PDIP package supports through-hole insertion, but add adequate clearance around the socket and account for lead-bend radius and soldering clearance.
Keep short, low-impedance supply and ground connections, and route any externally switched signals away from sensitive input paths. Because the supplied data does not specify I/O capacitance, output drive, or input thresholds, begin with the official electrical characteristics and validate them under worst-case voltage and temperature. If a sensor or relay interface introduces slow edges or inductive transients, add the protection required by that interface rather than relying solely on MCU internal limits.
合規資訊
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The -I ordering is treated only as the verified industrial-temperature indication and is not expanded into an unprovided qualification claim.
