PIC16F15223-I/MG 概要
What is an 8-bit microcontroller? An 8-bit MCU is a single-chip computer whose internal ALU, registers, and data bus are 8 bits wide. Within the broader taxonomy, the PIC16F15223 belongs to the PIC16 family (mid-range 8-bit), which itself is part of the Microchip 8-bit PIC microcontroller line under the embedded microcontroller / embedded processing category. Its role in a system is to manage low-level digital I/O, run state machines, handle communication protocols, and interface with analog sensors at very low power.
Key differentiating features include Core Independent Peripherals (CIPs) that offload tasks from the CPU, Intelligent Analog capability (10-bit ADC with internal voltage reference), and Functional Safety documentation suitable for safety-critical designs. The 32 MHz speed delivers 8 MIPS of throughput, sufficient for sensor processing, simple protocol stacks, and PID loops.
Architecturally the device uses a Harvard RISC core with a 14-bit instruction word, an internal 32 MHz HFINTOSC, and a deep-sleep current in the XLP nanoWatt range. PPS allows remapping of digital peripherals onto most I/O pins, dramatically simplifying PCB routing in space-constrained designs such as 16-QFN layouts where every pin matters.
Typical uses include wearable fitness bands, smart sensor tags, low-power IoT end nodes, HVAC sensor transmitters, battery-powered remote controls, and consumer appliances. The wide 1.8-5.5V range allows direct operation from a single lithium cell or 2xAA/AAA batteries.
Design tip: route the exposed pad (EP) of the 16-QFN to a continuous ground copper pour with multiple thermal vias. Without adequate EP soldering the junction-to-ambient thermal resistance rises sharply and the part will derate or fail at higher ambient temperatures.

主な用途
PIC16F15223-I/MG の用途: 6 件s: Wearable Fitness Bands, Smart Sensor Tags, Battery-Powered IoT End Nodes, HVAC Sensor Transmitters, Consumer Appliance Controls, Industrial Remote Controls.
Wearable Fitness Bands
The PIC16F15223-I/MG is well-matched to wearable fitness bands where the 3x3 mm 16-QFN footprint is critical for miniaturized wristband PCBs. Its XLP nanoWatt sleep mode drops quiescent current into the nanoamp range, extending CR2032 coin-cell life beyond a year of typical use. The 10-bit ADC reads heart-rate, skin-temperature, and motion-sensor channels while the EUSART or I2C peripheral streams data to a paired BLE radio. PPS allows remapping the I2C and UART onto any available pin, which is invaluable when routing a dense wearable board. At 32 MHz the core computes basic step-counting and sleep-state algorithms in real time without burdening the radio host. The 1.8-5.5V range allows direct operation from the coin cell with no boost converter. Estimated battery life at one sample per minute exceeds 18 months.

Smart Sensor Tags
For RFID-style smart sensor tags and inventory telemetry, the PIC16F15223-I/MG provides enough compute to read multiple analog sensors, perform local averaging, and wake a transmitter on threshold events. The 256-byte SRAM is sufficient for sliding-window averaging of temperature/humidity samples while 3.5 KB Flash hosts the application state machine plus a small bootloader. Two PWM channels drive indicator LEDs or haptic elements, and the two CCP modules capture pulse-width events from external flow or rotation sensors. The wide 1.8-5.5V supply range tolerates Energizer lithium primary cells that drift in voltage over their service life. The Functional Safety documentation supports use in safety-instrumented industrial tagging systems. Estimated average current with a 1 Hz sample rate is in the single-digit microamp range.
おすすめ
Battery-Powered IoT End Nodes
The PIC16F15223-I/MG suits battery-powered IoT end nodes that must run for years on AA cells. Its XLP nanoWatt sleep current and 32 MHz HFINTOSC wake-up time let the firmware duty-cycle between deep sleep and active bursts. The 10-bit ADC digitizes battery voltage, environmental sensors, or analog front-end outputs while the SPI peripheral interfaces to sub-GHz transceivers like Microchip's own MRF89XA family. PPS is critical in 16-QFN layouts because it lets designers reassign UART/SPI to whichever pins are not blocked by the radio's SPI bus, simplifying routing. The 8 MIPS throughput is sufficient for AES-light encryption and packet handling in sub-GHz protocols. Estimated: at 0.1% duty cycle with 3V supply, average current stays below 10 microamps.
おすすめ
HVAC Sensor Transmitters
HVAC sensor transmitters benefit from the PIC16F15223-I/MG's industrial -40C to +85C rating and Functional Safety (FuSa) documentation. The 10-bit ADC reads 4-20 mA loop or 0-10V sensor signals with adequate resolution for HVAC control loops. Two PWM outputs drive valve actuators while the EUSART outputs BACnet or Modbus RTU frames over RS-485 transceivers. The 16-QFN package withstands the high-vibration rooftop equipment environment when properly soldered with the exposed pad grounded. Core Independent Peripherals allow the ADC-to-PWM chain to run without CPU intervention, freeing the core to handle the protocol stack. Estimated: at 100 Hz sampling, power consumption stays below 5 mA active.
おすすめ
Consumer Appliance Controls
Small consumer appliances - coffee makers, air purifiers, smart kitchen gadgets - benefit from the PIC16F15223-I/MG's combination of low cost (around $0.43 at qty 1000), compact 16-QFN package, and integrated peripherals. The two CCP modules capture button-press timing and generate IR carrier signals for remote-control functionality. The 10-bit ADC reads NTC thermistors for temperature regulation, while PWM drives TRIAC gates or MOSFET gates for heating elements and fan motors. The 1.8-5.5V supply accepts a wide range of wall-adapter-derived rails. Functional Safety documentation supports white-goods applications where fault detection is required. The small 3 KB-class Flash holds full application code including user-interface state machines.
おすすめ
Industrial Remote Controls
Industrial remote controls for cranes, material-handling equipment, and process-control pendants use the PIC16F15223-I/MG for its low-power XLP modes and industrial temperature range. The 32 MHz core debounces switch matrices and runs safety-critical firmware loops within deterministic timing budgets. Hardware Limit Timer (HLT) provides an independent watchdog-style safety boundary, valuable for SIL-rated pendant designs. The EUSART interfaces to wireless modules or CAN transceivers. Functional Safety documentation assists certification. The 16-QFN package fits compact pendant enclosures while PPS gives layout flexibility when the antenna placement constrains pin choices. Estimated active current at full 32 MHz is around 2 mA, enabling rechargeable coin-cell operation.

主な差別化要因
- Memory headroom for richer firmware （vs PIC16F15224-I/MG)

- Functional Safety documentation （vs PIC16F15243-I/MG)
設計ノート
Estimated: the 16-QFN (3x3 mm) has theta_JA near 50 C/W on a 1 oz 4-layer PCB when the exposed pad (EP) is soldered to a 1 square inch ground copper pour with thermal vias. Solder the EP - the central pad is the primary thermal path and also stabilizes the package against PCB flex. Without EP soldering, junction temperature can rise 30-50% above spec and the part will derate at higher ambient temperatures.
Place decoupling capacitors (100 nF ceramic plus 1-10 uF bulk) within 3 mm of the VDD and VSS pins. The 16-QFN has only one VDD pin (pin 16) and one VSS pin (pin 7), so a wide ground pour and a short, low-inductance VDD trace are essential. Microchip recommends the MPLAB X IDE device-specific BSP for board layout examples.
Do not exceed 5.5V on VDD - the PIC16F15223 is not 5V-tolerant on I/O and overvoltage can damage the internal clamping diodes. Do not omit the MCLR pull-up resistor on RA3 if MCLR is enabled in configuration bits. When using the internal HFINTOSC, verify the OSCTUNE register setting at production temperature because internal oscillator drift can affect UART baud-rate accuracy at the temperature extremes of the -40 to +85 C industrial range.
