PIC10F222-E/P - 8-Bit 8MHz Flash MCU | Microchip Technology
MPN： PIC10F222-E/P ✓ 啟用中PIC10F222-E/P 概覽
A microcontroller is a programmable semiconductor system that integrates a CPU core, program memory, data memory, and peripherals on one chip. The PIC10F222 belongs to the Microchip PIC10 family and combines a general-purpose 8-bit microcontroller architecture with flash-based configuration storage. Its fully static CMOS implementation is appropriate for embedded products that operate from a fixed supply and must maintain deterministic low-power behavior between external events.
The principal features of the PIC10F222-E/P include an 8-bit CPU, 33 RISC instructions, a 20-word program memory page structure, 768 bytes of flash program memory, and 16 bytes of data RAM. The device includes one 8-bit Analog-to-Digital Converter, four general-purpose I/O pins, a general-purpose input pin, and a multifunction MCLR/VPP pin. These resources allow a compact controller to combine digital control and analog measurement without requiring a separate ADC.
The CPU executes most instructions in one cycle, corresponding to 1 microsecond at the 8 MHz operating frequency. Program branches require two cycles, and the 12-bit instruction word provides code density for a small embedded controller. The flash-based architecture allows application firmware and configurable control parameters to be programmed or rewritten according to Microchip's programming specifications, supporting product customization and field updates where the end application permits reprogramming.
Typical uses include compact appliance controls, simple sensor interfaces, low-cost timers, LED sequencers, small motor or relay-control systems, battery-operated products, and general-purpose embedded-control boards. The PIC10F222-E/P is especially appropriate when a PCB requires a through-hole package, modest processing capacity, one ADC channel, and only a small number of I/O lines. The LCSC listing identifies the device as an 8-bit MCU and reports availability from $0.3689 in stock, subject to market movement.
Designers should preserve the MCLR/VPP behavior required by the selected programming method and confirm the oscillator, reset, and I/O configuration against the manufacturer data sheet before layout release. Because this is an 8-pin device with four general-purpose I/O pins, pin multiplexing must be checked in software. PCB artwork should follow the official 8-pin DIP footprint, and production programming should use the manufacturer's validated programming specification.
This page consolidates verified manufacturer and distributor information, separates the target grade from related catalog entries, identifies the verified 8 MHz, flash, RAM, package, and ADC characteristics, and explains where exact pin, packaging, and procurement data must still be confirmed. It also records the available same-family drop-in candidate without presenting cross-package or functional equivalents as direct replacements.

典型應用
PIC10F222-E/P 適用於 6 應用s: Compact Appliance Control, Single-Channel Sensor Interface, LED Sequencer and Indicator, Relay and Discrete Control, Battery-Operated Embedded Product, Programmable Timer and Sequencer.
Compact Appliance Control
PIC10F222-E/P fits compact appliance controls where an 8 MHz 8-bit processor, 768 bytes of flash, and 16 bytes of RAM are sufficient for a small state machine. The 8-pin DIP package simplifies through-hole prototyping and repair, while four general-purpose I/O lines can drive indicators, buttons, or a simple relay stage. The principal design constraint is memory: application firmware must fit inside 768 bytes, and all working variables must fit inside the confirmed 16 bytes of RAM. The device's one ADC channel should be reserved for a simple analog measurement rather than a multi-sensor acquisition system.
Single-Channel Sensor Interface
PIC10F222-E/P is suitable for a single-channel sensor interface when the measurement can be handled by its one 8-bit ADC channel. The microcontroller can acquire an analog value, apply thresholding or simple filtering within the available program memory, and update an output through one of its four general-purpose I/O pins. With only 16 bytes of RAM, the firmware should avoid large sample buffers and stream or process values individually. Designers should also verify the analog input voltage limits and acquisition timing in the official Microchip data sheet.
LED Sequencer and Indicator
PIC10F222-E/P can implement a compact LED sequencer, status indicator, or programmable signaling controller using its four general-purpose I/O outputs and 8 MHz operating clock. Most instructions execute in one cycle, allowing deterministic timing without a complex real-time operating system. The 768-byte flash area is sufficient for moderate lookup tables and timing sequences, whereas the 16-byte RAM limit favors compact state variables over frame buffering. Through-hole assembly also makes the controller practical for prototypes, hobby products, and low-volume production boards requiring easy manual service.
Relay and Discrete Control
PIC10F222-E/P is appropriate for small relay, latch, or discrete-load controllers when the logic remains modest. Four general-purpose I/O pins can operate driver inputs, indicator circuits, or interlock signals, and the 8 MHz RISC core provides more timing capability than a basic fixed-function timer. The controller should keep timing-critical debouncing and state management within the 16-byte RAM limit and place the available ADC channel where useful, such as supply or feedback monitoring. External transistor, flyback, isolation, and safety components remain outside the MCU and must be rated for the load.
Battery-Operated Embedded Product
PIC10F222-E/P can serve as the controller in a small battery-operated embedded product because it combines a fully static CMOS implementation with a modest 8 MHz clock and 768 bytes of flash. The device is better suited to intermittent event-driven operation than applications needing large data buffers, since its RAM is limited to 16 bytes. Low-power behavior still requires explicit configuration of oscillator, peripheral, and I/O states, as the supplied excerpts do not provide a complete current-consumption table. Validate sleep currents and wake-up behavior against the manufacturer data sheet for the selected configuration.
Programmable Timer and Sequencer
PIC10F222-E/P supports compact timer and sequencer products that combine elapsed-time counting with a small number of discrete outputs. Its 8 MHz clock and single-cycle instruction execution provide a straightforward timing base, while program branches remain limited to two cycles. The 768-byte program memory can hold substantial control logic for a small timer, and four I/O pins are adequate when the product does not need a display matrix or many status indicators. Use flash for nonvolatile settings and keep volatile timing state within the 16-byte RAM allocation.

設計說明
Use the official Microchip 8-pin DIP package drawing rather than estimating pad spacing from the body width. Confirm the hole diameter, row spacing, pin-1 orientation, and solder clearances against the current package drawing. Leave adequate spacing around MCLR/VPP for programming access, and check the selected oscillator component layout against the manufacturer's recommended application circuit.
Place the input bypass capacitor and required decoupling directly between VDD and VSS pins on the PCB. Follow the capacitor value, voltage rating, and ESR guidance in the official PIC10F220/222 data sheet. Because the supplied excerpts do not provide verified operating-voltage limits or current-consumption figures, these values must be obtained from the manufacturer data sheet before selecting the supply and power components.
Do not treat PIC10F222-E/OT, PIC10F222T-I/OT, or other surface-mount order codes as direct replacements for the 8-PDIP target. Also do not assume that every suffix change preserves the commercial temperature grade. Verify the exact suffix, package drawing, programming method, pin configuration, and environmental requirements when changing from PIC10F222-E/P to PIC10F222-I/P.
Keep the eight-pin controller's functional signals short and isolate the analog input from switching nodes and high-current traces. If the ADC input is used, provide a stable source impedance and follow the manufacturer sample-and-hold guidance. Where an oscillator is used, maintain the recommended placement and grounding arrangement to avoid coupling clock noise into the measurement path.
合規資訊
The supplied excerpts confirm an operating-temperature listing of -40 C to +125 C but do not provide product-specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed from the current Microchip product material or manufacturer declarations.
