MPN: PIC10F220T-I/MC ✓ Hoạt độngPIC10F220T-I/MC Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripherals into one package. Within the broader taxonomy, the PIC10F220 belongs to the 8-bit microcontroller hypernym, the PIC10F family, and the Microchip PIC10F2xx sub-family. It is purpose-built for glue-logic replacement, logic-level translation, and ultra-compact analog or digital control nodes where board area and BOM cost dominate the design.
Key features include 4 MHz internal oscillator calibration within +/-1 percent, an 8-bit timer/counter (TMR0), a watchdog timer with on-chip oscillator, an 8-bit A/D converter with up to 6 input channels, and an in-circuit serial programming (ICSP) interface. The device operates across 2.0V to 5.5V, with a 1.8V brown-out-reset option, and supports industrial -40C to +85C temperature range. The I suffix confirms the industrial operating range; the T suffix denotes tape-and-reel packaging.
The PIC10F220 employs a RISC Harvard architecture with separate program and data buses, a 12-bit instruction word, and a deterministic two-stage pipeline. A comparator and internal voltage reference (0.6V nominal) are integrated for analog signal conditioning without external components. Power management features include an ultra-low-power sleep mode with wake-on-change I/O and selectable oscillator modes for system-level energy optimization.
Typical applications include consumer-electronics remote controls, battery chargers, LED driver controllers, sensor signal conditioning, low-power security sensors, and industrial control logic. The combination of 6 I/O pins, integrated ADC, and tiny DFN package makes it ideal for space-constrained designs.
When designing, ensure decoupling caps are placed close to VDD, avoid using GP3 as input only (it is input-only), and leverage the internal 4 MHz oscillator to minimize external component count. Consider the newer PIC10F322 for new designs, which adds more memory, PWM, and a CWG.

Ứng dụng tiêu biểu
PIC10F220T-I/MC phù hợp cho 6 Áp dụngs: Battery-Powered Remote Control, LED Driver Controller, Sensor Signal Conditioning, Low-Cost Consumer Electronics Logic Replacement, Security and Accessory Sensors, Industrial Control Logic.
Battery-Powered Remote Control
The PIC10F220T-I/MC suits coin-cell or two-AAA powered remote controls where BOM area and quiescent current are tightly constrained. With 384B Flash it can hold a basic key-scan + transmit state machine, while the 4 MHz internal oscillator eliminates an external crystal and the integrated 8-bit ADC reads battery voltage for low-battery indication. The DFN-8 (2x3 mm) package is small enough to fit inside a key-fob housing alongside a single CR2032 cell. Sleep-mode current and the ability to wake on I/O change make it ideal for multi-year battery life.
Được đề xuất
LED Driver Controller
The PIC10F220T-I/MC drives a constant-current LED string by combining its 8-bit ADC (for sensing LED current via a shunt) with a PWM-emulated control loop on a single GPIO. The internal 4 MHz oscillator is accurate enough to maintain 1 percent LED brightness matching without external trim. The wide 2.0V-5.5V supply range supports 3.3V and 5V LED driver rails. With 16B RAM and 384B Flash the part can implement up to four brightness presets and a fade-in/out ramp while leaving code space for thermal protection logic.
Được đề xuất
Sensor Signal Conditioning
The PIC10F220T-I/MC is a strong fit for analog sensor signal conditioning in the smallest possible footprint. The 8-bit ADC and internal voltage reference (0.6V) read resistive sensors such as thermistors, photodiodes, or simple strain gauges, while the integrated comparator triggers threshold-based interrupts without CPU polling. The -40C to +85C industrial temperature range supports outdoor and industrial sensor nodes. The DFN-8 (2x3 mm) package fits inside the sensor housing itself, enabling miniaturized smart-sensor modules.

Low-Cost Consumer Electronics Logic Replacement
The PIC10F220T-I/MC replaces discrete CMOS logic and small PLDs in consumer appliances where firmware configurability cuts BOM cost. With 33 instructions and 384B Flash it can implement 555-style timers, debounced switch inputs, sequence controllers, and motor pulse trains. The 4 MHz internal oscillator is accurate enough for timing-critical consumer tasks such as toy motor speed control or simple alarm-tone generation. The DFN-8 (2x3 mm) package integrates into extremely tight layouts, and the 2.0V-5.5V supply range operates directly from 2xAA alkaline cells.
Được đề xuất
Security and Accessory Sensors
The PIC10F220T-I/MC fits door/window magnetic sensors, PIR motion pre-processors, and tamper-detection modules that need a tiny MCU with analog sensing and a long-life battery. The 8-bit ADC monitors a reed switch or PIR analog output, while sleep mode with wake-on-change I/O extends coin-cell life to multiple years. The watchdog timer with on-chip oscillator provides robust recovery from ESD-induced firmware stalls in field-deployed sensors. The DFN-8 (2x3 mm) footprint sits inside a coin-cell holder alongside a wireless transmitter.
Được đề xuất
Industrial Control Logic
The PIC10F220T-I/MC suits small industrial control nodes such as relay drivers, optocoupler interfaces, and 24V-signal level translators. The 5.5V absolute-maximum supply handles 5V industrial rails with margin, and the input-only GP3 pin works as a hardware interrupt source for fast event capture. The 8-bit ADC reads 4-20 mA current loop sense resistors or 0-10V divided feedback. The -40C to +85C industrial temperature range covers factory-floor and outdoor cabinet environments. Tape-and-reel packaging supports high-volume SMT production.

Ghi chú thiết kế
Place a 0.1 uF decoupling capacitor as close as physically possible to the VDD pin (pin 1) and VSS (pin 5) of the DFN-8 package. For designs operating above 4 MHz with switching loads, add a bulk 1-10 uF tantalum or ceramic on the same supply rail within 5 mm of the MCU. The 2.0V-5.5V wide supply range allows direct connection to 2xAA alkaline cells without a boost converter, but verify brown-out-reset behavior at 1.8V if battery-end-of-life is part of the design. The internal 4 MHz oscillator accuracy is +/-1% at 5V/25C but degrades to +/-2% across the full voltage and temperature range, which matters for UART or IR timing-sensitive applications.
GP3 (pin 6) is input-only and is multiplexed with MCLR. Using it as a digital output will not work and may damage the pin if the corresponding TRIS bit is cleared. When MCLR is disabled in configuration bits, GP3 becomes a regular digital input. Configuration bits must be set explicitly in source code - leaving them at the default may enable the watchdog timer unintentionally, causing unexpected resets. The ADC input channels are shared with digital I/O, so configure the corresponding ANSEL bit before reading analog values to disable the digital input buffer and prevent back-driving.
Estimated: the PIC10F220T-I/MC in the DFN-8 (2x3 mm) package has a typical theta_JA of approximately 70 C/W on a standard 4-layer JEDEC test board. The absolute maximum junction temperature is 150C, but operation above 125C is not recommended. For most low-power digital applications at 4 MHz, self-heating is negligible (< 5 mW dissipation). The exposed pad is the only thermal path and should be soldered to the PCB for reliable operation, even though the pad is electrically floating. In battery-powered designs where ambient temperature swings are large, derate the oscillator accuracy and verify brown-out behavior at cold temperatures.
