PIC10F204-E/P - 8-Bit Flash MCU, 384B, 4MHz | Microchip
MPN: PIC10F204-E/P ✓ सक्रियPIC10F204-E/P अवलोकन
An 8-bit microcontroller such as the PIC10F204 is a complete computing element: a CPU core, program Flash, working data RAM, I/O ports, and oscillator all integrated on one chip. Within the product hierarchy it sits at the lowest-cost tier of embedded processing, below 16-bit and 32-bit MCUs, where the design goal is minimal component count and minimal board area for simple control, sensing, and signal-shaping tasks rather than high-throughput computation.
Key features of the PIC10F204-E/P include a RISC core with only 33 single-word, single-cycle instructions, a 12-bit wide instruction word that typically yields 2:1 code compression over competing 8-bit architectures, a fully static design that holds state in low-power operation, and an on-chip internal oscillator that eliminates an external crystal or resonator. The device operates across a 2.5 V to 5 V supply range, giving design headroom for both 3.3 V and 5 V systems.
Technically, the PIC10F204 executes single-cycle instructions in approximately 1 us at 4 MHz, with only program branches taking a second cycle. Program memory is organized as 256 words of 12 bits, while the data RAM is organized as 16 x 8 bits, which defines how much working state a design can hold. Because the core is fully static, the instruction clock can be stopped without losing register contents, a feature used for wake-on-activity designs.
Typical uses include low-cost on/off control for appliances and lighting, small sensor and threshold modules, timer-based control for pumps and fans, battery-backed keypads and remote controls, and simple LED indicator or relay driver boards where only a handful of I/O pins and a few hundred bytes of code are required.
Design guidance: keep the I/O pins close to their loads, add 100 nF decoupling at VDD, and remember that the 384-byte Flash budget fills quickly if you use library-heavy C code; the PIC10F204-I/P is the industrial-temperature option if you do not need -40 C to +125 C range. This page combines verified distributor data, drop-in alternatives, and design notes that are not consolidated in the manufacturer datasheet itself.

सामान्य अनुप्रयोग
PIC10F204-E/P के लिए उपयुक्त है 6 अनुप्रयोगs: Low-Cost Appliance Control Board, Simple Sensor and Threshold Module, Battery-Powered Remote and Keypad Controller, LED Driver and Lighting Controller, Motor, Pump and Timer Control Module, Serial Interface and Protocol Bridge.
Low-Cost Appliance Control Board
The PIC10F204-E/P fits appliance sub-assemblies such as fans, mixers, kettles, and small kitchen tools where the control task is a state machine over a handful of switches and indicators. Its 384 bytes of Flash and 16 bytes of RAM are enough for debounce logic, timer sequences, and a relay or triac drive, while the internal 4 MHz oscillator removes the cost and board area of a crystal. Because the core is fully static, the MCU can idle between events without losing state, cutting standby current in mains-powered products that must meet standby limits. The 8-pin PDIP footprint keeps assembly simple on hand-soldered or through-hole production lines, and the -E grade covers -40 C to +125 C for designs near ovens, motors, or heated compartments. The tradeoff is that any feature growth pushes past 256 words of program memory quickly, so plan the feature set carefully before committing.

Simple Sensor and Threshold Module
The PIC10F204-E/P is a natural fit for standalone sensing modules that convert an analog or discrete input into a switch or serial output, such as water-leak detectors, door contacts, temperature threshold switches, and simple level probes. Only 3 to 4 I/O lines are needed to read a comparator or sensor output, drive an indicator LED, and report status over a one-wire or UART-style link. Its 16 bytes of RAM imposes a deliberate design discipline, so designers typically run a rolling filter rather than buffering samples, which suits slow-changing physical quantities. The 2.5 V to 5 V operating range allows direct operation from a 3.3 V sensor rail without a level shifter, and the internal oscillator is adequate because threshold modules do not need precise timekeeping. Extended temperature from -40 C to +125 C supports deployment in cabinets, vehicles, and outdoor enclosures.

Battery-Powered Remote and Keypad Controller
The PIC10F204-E/P works well in handheld remotes, small keypads, and battery-backed access controllers where the device wakes briefly, scans a matrix of a few keys, sends a code, and returns to sleep. Its fully static core lets the designer stop the instruction clock between scans without losing register contents, and the low 2.5 V minimum supply permits a single-cell or coin-cell source with direct drive of the I/O pins. The 384-byte Flash budget is appropriate for short fixed code sequences rather than elaborate key decoding, and the 16 bytes of RAM must cover the scan buffer plus the transmit frame. Through-hole PDIP packaging is advantageous here because these products are often hand-assembled and field-replaceable. Honest limitation: internal oscillator accuracy is coarse, so any design requiring time-based anti-passback or rolling codes should move to a part with a timer and a more accurate clock source.
अनुशंसित
LED Driver and Lighting Controller
The PIC10F204-E/P is used in small LED lighting controllers, indicator panels, and decorative light drivers where the task is sequencing channels and applying simple fade or strobe patterns. Its 16-byte RAM is enough to hold a small pattern table and a timing index, and the single-cycle instruction throughput at 4 MHz provides enough resolution for flicker-free PWM-style effects implemented in software. The device's small 8-pin PDIP footprint suits densely packed LED boards and reduces board area compared with larger controllers. If the design is mains-adjacent, note that the PIC10F204-E/P is not isolated; a certified off-line supply and optocoupled drive stage should be used, with the MCU on the isolated secondary side driving MOSFET or transistor stages through the I/O pins. The 2.5 V to 5 V range also allows it to be powered directly from a regulated LED driver output rail, further simplifying the secondary side.

Motor, Pump and Timer Control Module
The PIC10F204-E/P is well matched to compact timer-driven modules such as irrigation timers, small pump controllers, fan speed sequencers, and dispensing counters, where a countdown and a single actuator output are all that is required. A single timer interrupt with a 16-byte RAM is adequate for counting and debouncing, and the internal oscillator is normally sufficient because the timing accuracy required is on the order of seconds, not microseconds. The 8-pin PDIP construction is mechanically robust for vibration-prone industrial enclosures and simplifies replacement in the field. If the module sits near a motor or a long cable run, transient protection on the I/O pins and bulk decoupling at VDD are essential, since the device provides no internal protection diodes beyond its general GPIO structure. Design headroom is tight: adding more channels or faster timing means stepping up to the larger PIC10F family members that keep the same 8-pin footprint.
अनुशंसित
Serial Interface and Protocol Bridge
The PIC10F204-E/P can act as a small protocol translator or a simple UART/one-wire repeater in accessories that must adapt a legacy serial port to a modern host. Three or 4 I/O lines are sufficient for a UART TX/RX pair plus one handshake or indicator output, and 384 bytes of program memory can hold a compact byte-level state machine that buffers, reformats, or echoes traffic. This is a typical use for the internal oscillator, since UART tolerance at moderate bit rates does not demand crystal accuracy. The 2.5 V to 5 V range lets the same design sit on either a 3.3 V logic rail or a legacy 5 V port. Realistic limitation: with 16 bytes of RAM there is no room for large frame buffers, so protocols requiring full-frame storage should use a higher-end UART-equipped MCU. The PDIP package also keeps prototyping and rework simple for one-off interface boxes.

डिज़ाइन नोट्स
Decouple VDD with a 100 nF ceramic capacitor placed as close as possible to pin 5, with a 1 uF bulk capacitor in parallel if the supply wiring runs more than a few centimeters. The PIC10F204 operates from 2.5 V to 5 V, but the internal oscillator and core current draw rise with supply voltage, so operating from 3.3 V rather than 5 V reduces dissipation in battery designs. If the device is powered from a switched source, add a reverse-blocking or discharge path so that residual charge on the supply rail does not leave the MCU in an indeterminate state at power-down.
The 8-pin PDIP footprint gives generous lead spacing (100 mil), which simplifies hand soldering and rework but consumes more board area than the surface-mount members of the PIC10F200/2/4/6 family. Keep the DIP away from heat sources such as linear regulators or power converters, and orient it with the pin-1 notch or dimple toward the board edge for easy inspection. If the product volume justifies a layout change, migrating to the SOIC-8 or SOT-23 version of the same die is straightforward at the schematic level but requires a new footprint and layout.
The two most common mistakes with the PIC10F204 are underestimating code size and miscounting usable I/O. Program memory is only 384 bytes organized as 256 words of 12 bits, so library-heavy C code can overflow the image; verify the compiled size for every build. Second, the available I/O count is reported as 3 by some distributors and 4 by others because dedicated input-only and output-only port lines are counted differently. Map your signals to the published GP0/GP1/GP2/GP3/GP4/GP5 pin function table in the family datasheet rather than relying on the listing headline.
Although the internal oscillator removes the need for a crystal, the supply pins still need a clean return path. Route the VSS connection directly to the ground plane rather than through the same trace that carries relay or motor currents, and keep switching-node copper at least a few millimeters from the DIP leads. If an I/O drives an inductive or long cable run, add series damping and a clamp to ground so that ESD and switching transients do not exceed the port ratings of the device.
Estimated power consumption: with a 5.0 V supply, a 4 MHz internal oscillator, and the MCU active in a typical I/O polling loop, average supply current is on the order of a few hundred microamps, giving roughly 1 to 2 mW of dissipation. With the core stopped between events, average current falls to microamps. This estimate is derived from the 4 MHz clock rate and the 2.5 V to 5 V supply range published for the device, not from a datasheet power table, so validate it in your own firmware duty cycle before sizing a coin cell.
